Getting Started with Network Design 🧠🌐

#coding#programming#orhanergun#webdev

Are you building a scalable and secure network for the first time? Here's a beginner-friendly guide to get you started with network design fundamentals.

🧩 What Is Network Design? Network design is the process of planning the structure of a computer network—whether it's for a small office, a campus, or a global enterprise. It involves identifying business needs, selecting hardware/software, and defining how devices will communicate.

Think of it as an architect’s blueprint—only for data, not buildings.

🧱 Core Components of a Network Before diving into design, it’s important to know what makes up a network:

Routers: Connect different networks together.

Switches: Connect devices within the same network.

Firewalls: Protect your network from unauthorized access.

Access Points: Allow wireless devices to connect to the network.

Cabling or Wireless Links: Physical or radio-based communication paths.

🗺️ Step-by-Step: Designing a Basic Network Here’s a simplified roadmap to start designing a small to medium-sized network:

Define Requirements Ask:

How many users or devices will connect?

What are the performance needs? (e.g., speed, uptime)

Are there remote or mobile users?

What applications will run on this network?

Create a Network Topology Choose a logical layout:

Star topology: Common and simple (e.g., one central switch).

Mesh topology: High redundancy (used in critical systems).

Hybrid: A mix of both, which is common in larger setups.

Tip: Use tools like draw.io or Cisco Packet Tracer to visualize your design.

Select Hardware and IP Schema Choose devices based on your budget and needs:

Cisco, Juniper, MikroTik (enterprise)

TP-Link, Ubiquiti (SMBs)

Plan IP addressing:

Use private IP ranges (e.g., 192.168.1.0/24)

Avoid IP conflicts using DHCP or static planning.

Add Security Layers Firewalls, VLANs, and ACLs (Access Control Lists)

Enable port security on switches

Use VPNs for remote access

Plan for Scalability and Redundancy Design with future growth in mind

Consider redundant links and failover strategies (e.g., dual routers)

🧪 Test Your Design Use simulation tools:

Cisco Packet Tracer

GNS3

EVE-NG

Before deploying a real network, simulate traffic, check for bottlenecks, and validate security.

🛠️ Tools to Help You Design Tool Purpose Cisco Packet Tracer Network simulation SolarWinds IPAM IP address management Wireshark Network traffic analysis draw.io Network diagrams

📌 Final Thoughts Network design is more than just connecting wires—it's about planning for performance, security, and growth. Whether you’re building a home lab or laying out an enterprise infrastructure, starting with a solid design can save you from major headaches later.

If you're just getting started, experiment, document everything, and stay curious. 💡

Load Balancing and High Availability for Full-Stack Applications

In a modern web development landscape where users expect 24/7 accessibility and rapid performance, full-stack applications must be designed for both scalability and resilience. Two critical components that ensure this reliability are load balancing and high availability (HA). Comprehending and applying these concepts is essential for any developer, and they form a vital part of the curriculum in a full-stack developer course, especially a full-stack developer course in Mumbai.

What is Load Balancing?

This is the process of distributing incoming network traffic across multiple servers or services to prevent any one component from becoming a bottleneck. When properly implemented, it ensures that:

No single server becomes overwhelmed

Resources are used efficiently

Applications remain responsive even under high traffic

Load balancers can operate at different layers:

Layer 4 (Transport Layer): Balances traffic based on IP address and port.

Layer 7 (Application Layer): Makes decisions based on content like URL paths, cookies, or headers.

Why Load Balancing is Important for Full-Stack Applications

A typical full-stack application includes a frontend (React, Angular), a backend (Node.js, Django), and a database. If the backend becomes overwhelmed due to increased requests—say, during a product launch or seasonal sale—users might face delays or errors.

A load balancer sits between users and the backend servers, routing requests intelligently and ensuring no single server fails under pressure. This approach improves both performance and reliability.

For frontend traffic, Content Delivery Networks (CDNs) also act as a form of load balancer, serving static files, for e.g. HTML, CSS, and JavaScript from geographically closer nodes.

What is High Availability (HA)?

This refers to systems designed to be operational and accessible without interruption for a very high percentage of time. It typically involves:

Redundancy: Multiple instances of services running across different nodes.

Failover Mechanisms: Automatic rerouting of traffic if a service or server fails.

Health Checks: Regular checks to ensure servers are active and responsive.

Scalability: Auto-scaling services to meet increased demand.

Incorporating HA means building systems that can survive server crashes, network failures, or even regional outages without affecting the end-user experience.

Tools and Techniques

Here are key technologies that support load balancing and high availability in a full-stack setup:

NGINX or HAProxy: Commonly used software load balancers that distribute requests across backend servers.

Cloud Load Balancers: AWS Elastic Load Balancer (ELB), Google Cloud Load Balancing, and Azure Load Balancer offer managed solutions.

Docker and Kubernetes: Deploy applications in container clusters that support automatic scaling, failover, and service discovery.

Database Replication and Clustering: Ensures data availability even if one database node goes down.

Auto Scaling Groups: In cloud environments, automatically launch or terminate instances based on demand.

Real-World Application for Developers

Imagine an e-commerce platform where the homepage, product pages, and checkout system are all part of a full-stack application. During a major sale event:

The frontend receives heavy traffic, served efficiently through a CDN.

Backend servers handle search, cart, and payment APIs.

A load balancer routes incoming requests evenly among multiple backend servers.

Kubernetes or cloud instances scale up automatically as traffic increases.

In the event that a server fails for any reason, the load balancer automatically directs traffic to functioning servers, guaranteeing high availability..

This kind of architecture is precisely what students learn to build in a full-stack developer course in Mumbai, where practical exposure to cloud platforms and containerisation technologies is emphasised.

Conclusion

Load balancing and high availability are no longer optional—they're essential for any production-ready full-stack application. These strategies help prevent downtime, improve user experience, and ensure scalability under real-world conditions. For learners enrolled in a java full stack developer course, especially those in dynamic tech hubs like Mumbai, mastering these concepts ensures they’re well-prepared to build and deploy applications that meet the performance and reliability demands of today’s digital economy.

Creating Immersive Pixel Art Displays for Live Events

Ever walked into a concert venue and felt like the visuals were alive—rippling in time with the beat or changing colors as the crowd moved? That’s the magic of an immersive pixel art display: a dynamic canvas built from thousands of little LED pixels that react, evolve, and invite interaction. In this post, we’ll explore how LED pixel displays are transforming pixel art live events, and how you can design an installation that feels both mesmerizing and meaningful.

What Is an LED Pixel Display?

An LED pixel display is made of individual light modules—think tiny RGB LEDs arranged in grids or strips. Each LED can change color and brightness independently, forming a pixel. When animated cohesively, these pixels form moving images, text, or abstract stories that dance across a stage or backdrop. For designers, the challenge is to turn static visuals into interactive pixel art that responds to sound cues, audience movement, or timecode, creating a fully immersive experience.

Why Pixel Art Displays Captivate Audiences

High Visual Impact Pixel arrays can render bold graphics and motion visuals that would be impossible with static sets.

Customization & Interactivity Integrate sensors or music triggers so the art reacts in real time—light pulses synced to bass drops, or waves that follow the crowd.

Versatility     From linear LED strips to massive wall-mounted grids, pixel art       displays can fit stages, domes, trusses—or even handheld gear.

Building Blocks of an Immersive Pixel Art Display

LED Pixel Modules & Pitch

Pixel pitch refers to the distance between center points of LEDs: smaller pitch (~4 mm) gives crisp, sharp images; larger pitches (>10 mm) are ideal for long-throw setups.

Choose modules rated for outdoor use (IP65+) for durability at outdoor live events or festivals.

Controllers & Protocols

Controllers drive animations via WS2812, SK6812, or DMX protocols. These bridge the gap between creative content and hardware. A reliable pixel controller can come from a reputable professional shop—ensuring quality performance and continued tech support.

Power & Signal Management

LEDs need steady power—usually 5 V or 12 V—so calculate amps per segment and add power injection points.

Extend signal using buffers or data repeaters to maintain sync across your entire display.

Designing the Content

Concept & Storyboarding

Start with a visual concept—synth-wave animation, audio-reactive waves, or VR-integrated graphics. Sketch storyboards and run test animations in software like TouchDesigner or Processing.

Mapping Your Grid

Accurate grid mapping—drawing each pixel's real-life position in your software setup—is critical. Even a small offset can skew the entire display.

Audio-Visual Integration

Link visuals to music using MIDI, OSC, or SMPTE timecode so the animation responds seamlessly to every beat, vocal cue, or lighting change.

Rigging & Setup Tips

Modular Structure Build your display from panels or strips that connect easily on-site. This makes installation smooth and maintenance easier.

Cable OrganizationLabel data and power lines. Use Velcro or cable ties to keep everything neat and trip hazards at bay.

Testing & CalibrationAlways do a full tech rehearsal. Look for dead or dim pixels, color shifts, or lag between triggers and playback.

Real-World Use Case

Take a mid-sized festival: festival-goers wear LED wristbands that light up with crowd cheers, while a massive pixel art wall echoes those patterns behind the stage. The result: a unified, reactive stage design that visually bonds the audience to the performance.

Best Practices for Success

Plan for failure: keep spare strips, controllers, and power supplies on hand.

Use compression-friendly content: looped animations or GIF-style visuals keep playback smooth.

Label everything: from IP addresses on networked controllers to physical cable runs, clarity speeds up setup and troubleshooting.

Document your setup: a labeled wiring diagram helps future iterations go faster and safer.

Final Thoughts

The future of pixel art live events is bright—literally. LED pixel displays let you build immersive, interactive shows that stand out and resonate deeply. Whether it’s a club, concert hall, or outdoor festival, these displays combine creative design with technical precision to deliver truly memorable experiences.

When you're ready to source your LED strips, controllers, and power gear, working with a reputable professional shop ensures hardware reliability and the kind of expert advice that helps you push creative boundaries—and deliver shows that truly shine.

With careful planning, thoughtful design, and thorough testing, you're on your way to creating spectacular pixel-powered experiences that wow crowds and elevate your production game.

Setting up a Raspberry Pi is always an adventure, and our latest project has been no exception! We've been diving deep into the world of network configuration, and after a bit of head-scratching (and a few "aha!" moments), we've made some significant progress in understanding how to get our Pi to share its internet connection.

Initially, like many, we fell into a common trap. Our goal was to share the internet connection from our Raspberry Pi, and our first thought was to assign a static IP address to wlan0 – the wireless interface. The logic seemed sound: wlan0 is how the Pi connects to the internet (via a hotspot, in our case), so surely that's where the magic needed to happen, right?

Not quite!

After some experimentation and a healthy dose of troubleshooting, we realized a crucial distinction. While wlan0 receives the internet connection, it's not the ideal interface for sharing it in the way we envisioned. Think of it this way: wlan0 is like the person receiving a package at the door. They've got the package, but they're not the ones distributing it to everyone else in the house.

This led us to eth0 – the trusty wired Ethernet port. And that's where the real breakthrough happened! We had a lightbulb moment: eth0 is perfectly suited for sharing the connection.

Here's why eth0 is our new best friend for internet sharing:

* Dedicated Connection: eth0 allows for a direct, dedicated connection to another device, like a router or even another computer. This is ideal for creating a stable and reliable shared network.

* Logical Separation: By using eth0 to share, we can keep the wlan0 interface focused on its primary job: connecting to the internet. This simplifies the network topology and makes it easier to manage.

* Foundation for a Robust Setup: With eth0 as our sharing interface, we can now configure it to act as a DHCP server, enable IP forwarding, and set up Network Address Translation (NAT). These are the essential ingredients for turning our Raspberry Pi into a powerful internet gateway.

So, what's the plan moving forward?

Our focus has now shifted to configuring eth0. We'll be looking at:

* Assigning a static IP address to eth0: This will be the gateway for any devices connected to it.

* Enabling IP forwarding: This is the key to telling the Pi to route traffic between our wlan0 internet source and our eth0 shared network.

* Setting up a DHCP server (like dnsmasq) on eth0: This will allow devices connected to eth0 to automatically get an IP address from our Pi.

* Configuring iptables for NAT: This crucial step will ensure that devices on our eth0 network can access the internet through our wlan0 connection.

This project has been a fantastic learning experience, highlighting the importance of understanding the fundamental roles of different network interfaces. We're excited to get eth0 fully configured and unlock the full potential of our Raspberry Pi as an internet sharing hub.

Stay tuned for more updates as we continue to build out this network!

How Dynamic IPs Improve the Sustainability of Multi-Account Operations

In today’s digital landscape, managing multiple accounts on social media, e-commerce, or automation platforms often triggers strict anti-bot and anti-abuse systems. These systems are designed to detect unusual patterns—such as repeated logins from the same IP address—and may lead to account bans, verification loops, or shadowbans. That’s where dynamic IPs, especially residential ones, come into play.

Dynamic residential IPs mimic real user behavior by rotating legitimate IP addresses sourced from actual internet users. This provides geographic diversity and helps avoid the red flags that come with static data center IPs. For businesses and growth hackers running multi-account strategies, using a dynamic IP setup ensures each account appears to be operated by a unique individual.

Additionally, dynamic IP rotation can be automated, aligning with scheduled tasks, login intervals, or interaction triggers. This enhances operational efficiency and significantly reduces the risk of triggering security thresholds. Whether you're managing hundreds of social media accounts or conducting market research through automation tools, a dynamic IP infrastructure offers both scalability and resilience.

In short, leveraging dynamic IPs is not just a technical trick—it’s a strategic necessity for long-term, sustainable multi-account operations in a hyper-regulated digital world.

Why Every Crypto Wallet User Should Use a VPN (2025 Guide)

Managing your crypto wallet without a VPN is like leaving your house with the door wide open. Whether you're using MetaMask, Trust Wallet, or Ledger Live, your real IP address can expose your activity to trackers, exchanges, governments, and hackers — even when you think you're secure.

This guide explains why a VPN is essential in 2025 for anyone who takes wallet privacy seriously.

🦊 MetaMask, Phantom, Trust Wallet — They're All Leaking Your Location

DApps and Web3 interfaces load directly in your browser, and unless you’re actively hiding your IP, your location is visible with every transaction or interaction.

Even if your wallet is secure, the network layer often isn’t. This makes it easy for snoopers to tie your crypto wallet activity to your physical identity, especially on public WiFi or mobile networks.

🔐 The Benefits of Using a VPN for Your Wallet

Here’s what a reliable VPN does when you're sending, receiving, or just checking your balances:

✅ Hides your IP address from DApps and analytics trackers

✅ Encrypts wallet sync activity (like on Ledger Live)

✅ Prevents location-based verification triggers on exchanges

✅ Protects against data sniffing on public WiFi

✅ Adds an extra wall against phishing redirections

Whether you're buying an NFT on OpenSea or managing a multisig wallet on Gnosis Safe, your privacy is vulnerable without a tunnel encrypting all network traffic.

🛠️ Best VPN Features for Wallet Users

Not all VPNs are built the same — if you’re managing serious crypto funds, look for these:

No-Logs Policy: Your VPN provider shouldn’t log any of your browsing or IP history

Kill Switch: Automatically shuts off traffic if VPN disconnects mid-session

WireGuard Support: Fastest, most stable modern encryption protocol

Static IP Option: Keeps wallet sync errors and login re-verifications down

Multi-device Access: Run VPN protection across your mobile, desktop, and browser

📱 Use Cases Where a VPN Is Essential

MetaMask on Browser Block fingerprinting and RPC leaks by routing all traffic through a VPN first.

Trust Wallet on Public WiFi Hotel, airport, or coffee shop internet is notoriously dangerous. VPN encryption fixes that.

Ledger Live on Desktop Syncing with Ledger’s servers through a VPN ensures you’re safe even on compromised networks.

DApp Interactions Want to mint an NFT or sign a contract from a restricted region? A VPN lets you do it without geo-blocks or logging.

🚫 Risks of Using Wallets Without a VPN

IP Address Leaks DApps and analytics tools can easily tie your activity to a real-world identity.

DNS Leaks or WebRTC Exposure Even with HTTPS, your browser may still leak identifiable info unless tunneled.

Login Triggers Some exchanges or DeFi dashboards flag wallets logged in from multiple IPs — especially abroad.

WiFi Snooping Hotspots like Starbucks or hotel lobbies are prime hunting grounds for packet sniffers and MITM attackers.

🔍 Trusted VPNs That Work Great With Wallets

After testing across multiple chains and wallets, these are top picks:

PIA (Private Internet Access) – great for open-source fans and wallet compatibility

PureVPN – ideal for consistent IP and high-speed wallet syncing

FastestVPN – perfect if you want a reliable, budget-friendly wallet VPN setup

If you're serious about crypto in 2025, you can’t afford to expose your wallet to unnecessary risk.

Start using a VPN and make sure your wallet stays private — always.

How To Change Your Aws Ec2 Instance Type For A Seamless Hosted Ui-To-Backend Integration

In the world of web applications, linking a hosted user interface (UI) with a secure backend on an AWS EC2 instance is essential for creating a seamless, scalable, and secure user experience. This guide covers each step in the process, from launching and configuring an EC2 instance to implementing HTTPS for secure communication. By the end of this tutorial, you’ll have a practical understanding of how to connect a hosted UI to an EC2 backend, troubleshoot common issues, and maximize the power of AWS for a robust setup.

AWS EC2 instance types are categorized based on optimized use cases like compute, memory, storage, or GPU performance. Choosing the right instance type ensures efficient resource allocation and cost-effective application performance.

Step 1: Launch and Configure the EC2 Instance

The first step in setting up a backend server on AWS is creating an EC2 instance suited to handle your application’s workload. With AWS, you have full control over the instance, including scaling resources as traffic grows. Here’s how we set up the instance:

Select an Instance Type: Head over to the EC2 Dashboard in AWS, where you can launch a new instance. The t2.micro instance type is often a good choice for smaller projects or testing environments, but as application needs grow, selecting a larger instance type may be necessary for enhanced performance.

Assign an Elastic IP: Once the instance is launched, assign an Elastic IP to ensure that it maintains a static public IP address, even if the instance restarts. This makes it easy for your hosted UI to consistently access the backend without needing to update the endpoint.

Set Up Security Groups: AWS security groups act as a virtual firewall for your EC2 instance. Configuring inbound and outbound rules in these security groups is crucial to ensure that only trusted traffic reaches your server. We configured rules to allow incoming traffic on:

Port 80 (HTTP): Used to redirect traffic to HTTPS.

Port 443 (HTTPS): Enables secure encrypted connections.

Application-Specific Port (6879): The port where our application’s backend listens for requests.

By setting up these rules, we created a secure pathway for communication between our hosted UI and the EC2 instance.

Step 2: Retrieve Instance Metadata with IMDSv2

To simplify dynamic configurations, AWS provides the Instance Metadata Service (IMDS), which is especially useful for obtaining information about the instance itself, like its public IP. AWS recently enhanced the security of this service with IMDSv2, which requires a session token to access metadata.

We created a script that retrieves the public IP address of the instance. Here’s a quick look at how it’s done:goCopy codefunc getPublicIP() (string, error) { tokenReq, err := http.NewRequest("PUT", "http://169.254.169.254/latest/api/token", nil) if err != nil { return "", err } tokenReq.Header.Set("X-aws-ec2-metadata-token-ttl-seconds", "21600") client := &http.Client{} tokenResp, err := client.Do(tokenReq) if err != nil { return "", err } defer tokenResp.Body.Close() token, err := io.ReadAll(tokenResp.Body) if err != nil { return "", err } req, err := http.NewRequest("GET", "http://169.254.169.254/latest/meta-data/public-ipv4", nil) if err != nil { return "", err } req.Header.Set("X-aws-ec2-metadata-token", string(token)) resp, err := client.Do(req) if err != nil { return "", err } defer resp.Body.Close() body, err := io.ReadAll(resp.Body) if err != nil { return "", err } return string(body), nil }

By accessing metadata directly within the instance, this approach ensures that necessary details are always available, even if instance information changes.

Step 3: Generate and Embed SSL Certificates for HTTPS

A key part of connecting a UI to a backend is ensuring secure data transmission, which we accomplish by configuring HTTPS on the EC2 instance. We generated SSL certificates using OpenSSL and embedded them directly within the code.

Generate SSL Certificates with OpenSSL

We created a self-signed certificate and private key, which were then embedded within the application. This way, there’s no need to handle the certificates externally.bashCopy codeopenssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout server.key -out server.crt -subj "/CN=yourdomain.com"

Embed Certificates in the Code

With Go’s embed package, we could easily include the certificate and key within the application:goCopy code//go:embed certs/server.crt var serverCrtFile []byte //go:embed certs/server.key var serverKeyFile []byte

Embedding the certificates directly in the code makes deployment more straightforward, especially for EC2 instances that may be frequently restarted or replaced.

Step 4: Configure HTTPS with TLS in Go

Once the certificates were embedded, the next step was to configure HTTPS in our Go server to serve secure connections. We set up the server to serve HTTPS requests only when a public IP was available, using TLS to provide strong encryption.

Here’s how we configured the Go server to listen for secure connections on port 443:goCopy codeif ip != "" { cert, err := tls.X509KeyPair(serverCrtFile, serverKeyFile) if err != nil { log.Fatalf("Failed to load TLS certificates: %v", err) } httpSrv.TLSConfig = &tls.Config{ Certificates: []tls.Certificate{cert}, MinVersion: tls.VersionTLS12, } if err := httpSrv.ListenAndServeTLS("", ""); err != http.ErrServerClosed { log.Fatalf("GraphQL server failed to start with HTTPS: %v", err) } } else { if err := httpSrv.ListenAndServe(); err != http.ErrServerClosed { log.Fatalf("GraphQL server failed to start with HTTP: %v", err) } }

With this configuration, the server listens over HTTPS, ensuring that all communications between the UI and the backend are encrypted.

Step 5: Testing and Troubleshooting Common Issues

After setting up the server, thorough testing was essential to confirm that everything worked as expected.

Using OpenSSL for Certificate Validation

To ensure the certificate was properly configured, we validated it using OpenSSL:bashCopy codeopenssl x509 -in server.crt -text -noout

Testing the Connection with CURL

Using curl, we confirmed that the server was accessible over HTTPS:bashCopy codecurl -vk https://<public_ip>:6879/healthz

Common Issues and Solutions

TLS Handshake Errors:

This usually indicates a mismatch in TLS versions between the client and server. To resolve this, we enforced TLS 1.2 on the server.

Connection Refused:

This can happen if ports aren’t correctly opened. We confirmed that our security group allowed inbound traffic on all necessary ports (80, 443, 6879).

Certificate Warnings:

Since we used a self-signed certificate, some browsers and tools may show a warning. For production setups, consider using a certificate issued by a trusted Certificate Authority (CA).

Final Integration and Testing with the UI

With the EC2 backend fully configured, we tested end-to-end integration with the UI to ensure seamless communication between the frontend and backend. By securing each step, from security groups to TLS encryption, we created a setup that ensures both security and reliability.

AWS offers a robust EC2 API through which developers can control instances programmatically. You can use the API to launch, stop, start, terminate, and resize instance types without resorting to the AWS Console. This is particularly convenient for automation, scaling, and integrating EC2 management with custom applications or DevOps pipelines. All these tools such as the AWS CLI, SDKs, and CloudFormation operate using this API in the background to efficiently and securely communicate with EC2 resources.

How to monitor frequency of replacement of aws ec2 instances?

Here's a brief 6-line tutorial to monitor the frequency of EC2 instance replacement:

Tag instances with launch timestamps via instance metadata or automation tools.

Turn on AWS CloudTrail to record EC2 instance start/terminate events.

Monitor instance lifecycle changes using Amazon CloudWatch Logs/Events.

Build a CloudWatch Dashboard with custom metrics or filters for instance IDs.

Export logs to S3 and query with Athena or utilize AWS Config to monitor changes over time.

With AWS’s powerful infrastructure and EC2’s flexibility, this setup provides a robust foundation for web applications ready to grow and adapt to future needs.

FAQ’s

1. When I modify the instance type of an EC2 instance?

When you modify the instance type, AWS temporarily stops the instance.

You can then change its type and restart it with the new type.

All the data in the root volume is preserved unless deleted intentionally.

Ensure that the new instance type is supported by the current AMI and networking.

2. Will my Elastic IP be the same after instance type change?

Yes, if you have an Elastic IP associated, it will remain attached during the type change.

Elastic IPs persist through instance stops and starts.

Just make sure the instance is in the same region.

Without an Elastic IP, the public IP will change on restart.

3. How do I select the correct EC2 instance type for my application?

Evaluate your workload requirements: compute-intensive, memory-hungry, or storage-intensive.

Consult AWS's instance type recommendations and perform benchmarking if necessary.

Begin with general-purpose types such as t3 for development or low load.

Observe performance and grow vertically (change type) or horizontally (increase instances).

4. Can I automate changing EC2 instance types depending on usage?

Yes, you can do it automated with CloudWatch alarms and Lambda functions.

Set thresholds on CPU, memory, or network metrics.

When the threshold is breached, fire a Lambda script to terminate, reconfigure, and restart the instance.

Optimizes cost and performance with automated intervention.

LAN network covers small geographical area like homes, office or a school up to a range of 1km. Tamara, (2009) says that WAN covers a broad area of metropolitan, regional boundaries up to a distance of 10000km. LAN uses a peer to peer network topology while WAN, on the other hand, uses a Client to Server model of the topology. LAN uses Ethernet standard while WAN uses T1. LAN uses layer two devices switches and bridges and Layer 1 devices like hubs and repeaters. WAN mostly uses layer three devices like routers, multi-layer switches and other devices like ATM and Frame Relay switches. Question 3 The user that gave the request might not have correct access rights to the application given, and it will result into the request failing. The issues can be avoided by setting the client and server to be in the same Windows domain. Make sure the user id of the customer is configured on both the client and server computers. There might be a failed communication between the client and server due to faulty connection hardware or no internet. No connection problems can be avoided by first establishing if there is a link to the server through the ping command. Problems might arise from weak firewall configurations. Firewalls might deny a client access to certain resources on the server, (Tamara, 2009). The problem can be avoided by first disabling firewall to ascertain if that is the cause of the problem and then configuring the firewall setting for the client in question. The transmission might not be successful due to power or electricity interruptions of either the client or server or both. Power interruptions can be avoided by having power backups. Transmission problems might arise due to change of IP addresses. The problem can be solved when using DHCP by setting client lease time to at list 24hrs. The problem can also be solved assigning static IP addresses to client, server or both.Question 4 Setting up of the a WAN that covers a large area has a lot of challenges during the initial setup. The major challenges are staffing, existing applications, network equipment and managing connectivity outside of the primary organization location. Staffing and personnel implications to consider include; making sure that the correct employees with the required skills are available at every global location. The senior network designer should make sure there is constant communication with all the teams in all the locations. The personnel should have the correct motivation in terms of pay. Another staff implication from different regions is the situation of the working environment in their area. Barriers to an effective global team include: time restrictions where the working times are different which might create problems in coordination. Language barrier can also be a major challenge since there will be a lack of adequate understanding between the personnel. Other barriers include effective communication like challenges of video conferencing and coordination of all the staff and having the same schedule to adhere to is very hard.Question 5 Setting up an effective WAN network requires powerful equipment and servers to implement the network (Tamara, 2009). The devices that will be needed include; several workstations, printers Ethernet cables, layer three devices like routers and multilayer switches. Each location in Peru, France, Hungary will have several servers preferably windows server 2012. Tere shall be a windows server 2012 standard and data center edition. Since the main office will be in USA, the servers to be used will be mainly data center edition. Each of the global locations will have a primary server, file sharing server and print server. The location in the USA will also have a web server to handle the website of the company. Users in each location will be able to access specific files from any of the locations if they have the correct access rights. Read the full article

How Static ISP Proxies Help You Avoid CAPTCHA and Bans by Proxy Lust, Inc.

In the age of intelligent bot detection and hyper-vigilant web security, getting past CAPTCHA screens and IP bans is more challenging than ever. Businesses, marketers, and automation specialists are constantly battling access blocks and rate limits, especially when using traditional proxies.

Enter Static ISP Proxies—the sweet spot between residential authenticity and datacenter performance.

In this blog post, we’ll explore what static ISP proxies are, why they’re so powerful, and how they help you avoid CAPTCHA triggers, bans, and blocks.

🌐 What Are Static ISP Proxies?

Static ISP Proxies are IP addresses assigned by real Internet Service Providers (ISPs), hosted on powerful datacenter infrastructure. Unlike traditional datacenter IPs, which are often flagged due to known ranges, static ISP proxies appear as real residential connections to websites—but with the reliability and speed of datacenter networks.

Key characteristics:

IPs registered to real ISPs (e.g., Comcast, AT&T, Verizon)

Hosted on physical servers with high uptime

Assigned a static (non-rotating) IP address

Geolocated like typical home user connections

🛡️ Why CAPTCHA and Bans Happen

Websites and platforms use anti-bot technologies to protect themselves from abuse. These systems analyze patterns like:

Too many requests from a single IP

Use of known proxy/datacenter IPs

Repetitive or scripted actions

Inconsistent browser fingerprints

If a system suspects a bot or scraper, it will:

Present a CAPTCHA challenge

Trigger rate limiting

Temporarily or permanently ban the IP address

✅ How Static ISP Proxies Help You Stay Under the Radar

1. Residential Trust, Datacenter Stability

Because static ISP proxies are tied to real ISPs, they look like residential traffic, which reduces suspicion from web services. But unlike real residential proxies, they are always online, faster, and more reliable.

2. Avoid Triggering Anti-Bot Systems

Static ISP proxies don’t rotate like mobile or residential proxies, which means no IP jumping. This reduces fingerprint inconsistency and makes your requests look more natural to the target website.

3. Bypass CAPTCHA Screens

CAPTCHA triggers are often linked to:

Datacenter IPs

High activity from one source

Suspicious browser behavior

Static ISP proxies eliminate the first issue and can be paired with real browser environments (e.g., Puppeteer, Selenium with stealth plugins) to solve the others.

4. Reduce Account Lockouts

For users managing multiple social media, eCommerce, or ad accounts, static ISP proxies reduce the risk of login verifications, phone number checks, or temporary bans.

5. Persistent Sessions

Unlike rotating proxies, static ISP proxies maintain a single IP throughout a session or task. This makes them perfect for:

Logging in to accounts

Running long-term bots

Interacting with platforms that rely on consistent IP fingerprints
