SysNotes devlog 1

Hiya! We're a web developer by trade and we wanted to build ourselves a web-app to manage our system and to get to know each other better. We thought it would be fun to make a sort of a devlog on this blog to show off the development! The working title of this project is SysNotes (but better ideas are welcome!)

What SysNotes is✅:

A place to store profiles of all of our parts

A tool to figure out who is in front

A way to explore our inner world

A private chat similar to PluralKit

A way to combine info about our system with info about our OCs etc as an all-encompassing "brain-world" management system

A personal and tailor-made tool made for our needs

What SysNotes is not❌:

A fronting tracker (we see no need for it in our system)

A social media where users can interact (but we're open to make it so if people are interested)

A public platform that can be used by others (we don't have much experience actually hosting web-apps, but will consider it if there is enough interest!)

An offline app

So if this sounds interesting to you, you can find the first devlog below the cut (it's a long one!):

(I have used word highlighting and emojis as it helps me read large chunks of text, I hope it's alright with y'all!)

Tech stack & setup (feel free to skip if you don't care!)

The project is set up using:

Database: MySQL 8.4.3

Language: PHP 8.3

Framework: Laravel 10 with Breeze (authentication and user accounts) and Livewire 3 (front end integration)

Styling: Tailwind v4

I tried to set up Laragon to easily run the backend, but I ran into issues so I'm just running "php artisan serve" for now and using Laragon to run the DB. Also I'm compiling styles in real time with "npm run dev". Speaking of the DB, I just migrated the default auth tables for now. I will be making app-related DB tables in the next devlog. The awesome thing about Laravel is its Breeze starter kit, which gives you fully functioning authentication and basic account management out of the box, as well as optional Livewire to integrate server-side processing into HTML in the sexiest way. This means that I could get all the boring stuff out of the way with one terminal command. Win!

Styling and layout (for the UI nerds - you can skip this too!)

I changed the default accent color from purple to orange (personal preference) and used an emoji as a placeholder for the logo. I actually kinda like the emoji AS a logo so I might keep it.

Laravel Breeze came with a basic dashboard page, which I expanded with a few containers for the different sections of the page. I made use of the components that come with Breeze to reuse code for buttons etc throughout the code, and made new components as the need arose. Man, I love clean code 😌

I liked the dotted default Laravel page background, so I added it to the dashboard to create the look of a bullet journal. I like the journal-type visuals for this project as it goes with the theme of a notebook/file. I found the code for it here.

I also added some placeholder menu items for the pages that I would like to have in the app - Profile, (Inner) World, Front Decider, and Chat.

i ran into an issue dynamically building Tailwind classes such as class="bg-{{$activeStatus['color']}}-400" - turns out dynamically-created classes aren't supported, even if they're constructed in the component rather than the blade file. You learn something new every day huh…

Also, coming from Tailwind v3, "ps-*" and "pe-*" were confusing to get used to since my muscle memory is "pl-*" and "pr-*" 😂

Feature 1: Profiles page - proof of concept

This is a page where each alter's profiles will be displayed. You can switch between the profiles by clicking on each person's name. The current profile is highlighted in the list using a pale orange colour.

The logic for the profiles functionality uses a Livewire component called Profiles, which loads profile data and passes it into the blade view to be displayed. It also handles logic such as switching between the profiles and formatting data. Currently, the data is hardcoded into the component using an associative array, but I will be converting it to use the database in the next devlog.

New profile (TBC)

You will be able to create new profiles on the same page (this is yet to be implemented). My vision is that the New Alter form will unfold under the button, and fold back up again once the form has been submitted.

Alter name, pronouns, status

The most interesting component here is the status, which is currently set to a hardcoded list of "active", "dormant", and "unknown". However, I envision this to be a customisable list where I can add new statuses to the list from a settings menu (yet to be implemented).

Alter image

I wanted the folder that contained alter images and other assets to be outside of my Laravel project, in the Pictures folder of my operating system. I wanted to do this so that I can back up the assets folder whenever I back up my Pictures folder lol (not for adding/deleting the files - this all happens through the app to maintain data integrity!). However, I learned that Laravel does not support that and it will not be able to see my files because they are external. I found a workaround by using symbolic links (symlinks) 🔗. Basically, they allow to have one folder of identical contents in more than one place. I ran "mklink /D [external path] [internal path]" to create the symlink between my Pictures folder and Laravel's internal assets folder, so that any files that I add to my Pictures folder automatically copy over to Laravel's folder. I changed a couple lines in filesystems.php to point to the symlinked folder:

And I was also getting a "404 file not found" error - I think the issue was because the port wasn't originally specified. I changed the base app URL to the localhost IP address in .env:

…And after all this messing around, it works!

(My Pictures folder)

(My Laravel storage)

(And here is Alice's photo displayed - dw I DO know Ibuki's actual name)

Alter description and history

The description and history fields support HTML, so I can format these fields however I like, and add custom features like tables and bullet point lists.

This is done by using blade's HTML preservation tags "{!! !!}" as opposed to the plain text tags "{{ }}".

(Here I define Alice's description contents)

(And here I insert them into the template)

Traits, likes, dislikes, front triggers

These are saved as separate lists and rendered as fun badges. These will be used in the Front Decider (anyone has a better name for it?? 🤔) tool to help me identify which alter "I" am as it's a big struggle for us. Front Decider will work similar to FlowCharty.

What next?

There's lots more things I want to do with SysNotes! But I will take it one step at a time - here is the plan for the next devlog:

Setting up database tables for the profile data

Adding the "New Profile" form so I can create alters from within the app

Adding ability to edit each field on the profile

I tried my best to explain my work process in a way that wold somewhat make sense to non-coders - if you have any feedback for the future format of these devlogs, let me know!

~~~~~~~~~~~~~~~~~~

Disclaimers:

I have not used AI in the making of this app and I do NOT support the Vibe Coding mind virus that is currently on the loose. Programming is a form of art, and I will defend manual coding until the day I die.

Any alter data found in the screenshots is dummy data that does not represent our actual system.

I will not be making the code publicly available until it is a bit more fleshed out, this so far is just a trial for a concept I had bouncing around my head over the weekend.

We are SYSCOURSE NEUTRAL! Please don't start fights under this post

Structured Query Language (SQL): A Comprehensive Guide

 Structured Query Language, popularly called SQL (reported "ess-que-ell" or sometimes "sequel"), is the same old language used for managing and manipulating relational databases. Developed in the early 1970s by using IBM researchers Donald D. Chamberlin and Raymond F. Boyce, SQL has when you consider that end up the dominant language for database structures round the world.

Structured query language commands with examples

Today, certainly every important relational database control system (RDBMS)—such as MySQL, PostgreSQL, Oracle, SQL Server, and SQLite—uses SQL as its core question language.

What is SQL?

SQL is a website-specific language used to:

Retrieve facts from a database.

Insert, replace, and delete statistics.

Create and modify database structures (tables, indexes, perspectives).

Manage get entry to permissions and security.

Perform data analytics and reporting.

In easy phrases, SQL permits customers to speak with databases to shop and retrieve structured information.

Key Characteristics of SQL

Declarative Language: SQL focuses on what to do, now not the way to do it. For instance, whilst you write SELECT * FROM users, you don’t need to inform SQL the way to fetch the facts—it figures that out.

Standardized: SQL has been standardized through agencies like ANSI and ISO, with maximum database structures enforcing the core language and including their very own extensions.

Relational Model-Based: SQL is designed to work with tables (also called members of the family) in which records is organized in rows and columns.

Core Components of SQL

SQL may be damaged down into numerous predominant categories of instructions, each with unique functions.

1. Data Definition Language (DDL)

DDL commands are used to outline or modify the shape of database gadgets like tables, schemas, indexes, and so forth.

Common DDL commands:

CREATE: To create a brand new table or database.

ALTER:     To modify an present table (add or put off columns).

DROP: To delete a table or database.

TRUNCATE: To delete all rows from a table but preserve its shape.

Example:

sq.

Copy

Edit

CREATE TABLE personnel (

  id INT PRIMARY KEY,

  call VARCHAR(one hundred),

  income DECIMAL(10,2)

);

2. Data Manipulation Language (DML)

DML commands are used for statistics operations which include inserting, updating, or deleting information.

Common DML commands:

SELECT: Retrieve data from one or more tables.

INSERT: Add new records.

UPDATE: Modify existing statistics.

DELETE: Remove information.

Example:

square

Copy

Edit

INSERT INTO employees (id, name, earnings)

VALUES (1, 'Alice Johnson', 75000.00);

three. Data Query Language (DQL)

Some specialists separate SELECT from DML and treat it as its very own category: DQL.

Example:

square

Copy

Edit

SELECT name, income FROM personnel WHERE profits > 60000;

This command retrieves names and salaries of employees earning more than 60,000.

4. Data Control Language (DCL)

DCL instructions cope with permissions and access manage.

Common DCL instructions:

GRANT: Give get right of entry to to users.

REVOKE: Remove access.

Example:

square

Copy

Edit

GRANT SELECT, INSERT ON personnel TO john_doe;

five. Transaction Control Language (TCL)

TCL commands manage transactions to ensure data integrity.

Common TCL instructions:

BEGIN: Start a transaction.

COMMIT: Save changes.

ROLLBACK: Undo changes.

SAVEPOINT: Set a savepoint inside a transaction.

Example:

square

Copy

Edit

BEGIN;

UPDATE personnel SET earnings = income * 1.10;

COMMIT;

SQL Clauses and Syntax Elements

WHERE: Filters rows.

ORDER BY: Sorts effects.

GROUP BY: Groups rows sharing a assets.

HAVING: Filters companies.

JOIN: Combines rows from  or greater tables.

Example with JOIN:

square

Copy

Edit

SELECT personnel.Name, departments.Name

FROM personnel

JOIN departments ON personnel.Dept_id = departments.Identity;

Types of Joins in SQL

INNER JOIN: Returns statistics with matching values in each tables.

LEFT JOIN: Returns all statistics from the left table, and matched statistics from the right.

RIGHT JOIN: Opposite of LEFT JOIN.

FULL JOIN: Returns all records while there is a in shape in either desk.

SELF JOIN: Joins a table to itself.

Subqueries and Nested Queries

A subquery is a query inside any other query.

Example:

sq.

Copy

Edit

SELECT name FROM employees

WHERE earnings > (SELECT AVG(earnings) FROM personnel);

This reveals employees who earn above common earnings.

Functions in SQL

SQL includes built-in features for acting calculations and formatting:

Aggregate Functions: SUM(), AVG(), COUNT(), MAX(), MIN()

String Functions: UPPER(), LOWER(), CONCAT()

Date Functions: NOW(), CURDATE(), DATEADD()

Conversion Functions: CAST(), CONVERT()

Indexes in SQL

An index is used to hurry up searches.

Example:

sq.

Copy

Edit

CREATE INDEX idx_name ON employees(call);

Indexes help improve the performance of queries concerning massive information.

Views in SQL

A view is a digital desk created through a question.

Example:

square

Copy

Edit

CREATE VIEW high_earners AS

SELECT call, salary FROM employees WHERE earnings > 80000;

Views are beneficial for:

Security (disguise positive columns)

Simplifying complex queries

Reusability

Normalization in SQL

Normalization is the system of organizing facts to reduce redundancy. It entails breaking a database into multiple related tables and defining overseas keys to link them.

1NF: No repeating groups.

2NF: No partial dependency.

3NF: No transitive dependency.

SQL in Real-World Applications

Web Development: Most web apps use SQL to manipulate customers, periods, orders, and content.

Data Analysis: SQL is extensively used in information analytics systems like Power BI, Tableau, and even Excel (thru Power Query).

Finance and Banking: SQL handles transaction logs, audit trails, and reporting systems.

Healthcare: Managing patient statistics, remedy records, and billing.

Retail: Inventory systems, sales analysis, and consumer statistics.

Government and Research: For storing and querying massive datasets.

Popular SQL Database Systems

MySQL: Open-supply and extensively used in internet apps.

PostgreSQL: Advanced capabilities and standards compliance.

Oracle DB: Commercial, especially scalable, agency-degree.

SQL Server: Microsoft’s relational database.

SQLite: Lightweight, file-based database used in cellular and desktop apps.

Limitations of SQL

SQL can be verbose and complicated for positive operations.

Not perfect for unstructured information (NoSQL databases like MongoDB are better acceptable).

Vendor-unique extensions can reduce portability.

Pinball Machine: Cloud-Connected Retro Sandbox Gameplay

Pinball Machines

Google cloud frequently take for granted how simple it is to link apps with a wide range of robust cloud services in today’s cloud-centric world. Nonetheless, integration remains difficult in a great number of legacy systems and other restricted situations.

When creating Backlogged Pinball, a unique pinball game that created as a demonstration for integrating cloud services in unusual locations, they took on this difficulty head-on. A real pinball machine called Backlogged Pinball can be connected to the cloud for a number of purposes, such as updating leaderboards and tracking information about finished and ongoing games.

In order to concentrate on game coding and cloud integration, built it on the foundation of a commercially available programmable pinball machine. The computer’s software environment was constrained, though, as it was using a sandboxed version of the.NET Framework 3.5, which was initially made available 17 years ago. In practice, this meant that were unable to install tools like gcloud to facilitate communication with the cloud and utilize any of the current Google cloud SDKs that were available for C#.

There’s a catch

It knew wanted to use the cloud for logging of game events and results, databases for high scores and game statistics, and a custom service to modify the game experience on the fly. However, creating software for such a limited setting came with a number of difficulties that you may be familiar with:

Limited library support: There are plenty of excellent libraries available to assist you in connecting to cloud services if you have complete control over your stack. However, there are instances when you are unable to choose where your software runs. Finding appropriate libraries to connect Google cloud pinball machine to the desired cloud services proved to be challenging.

For instance, they were aware that in order to power a real-time display of every event occurring in the game, needed to add entries into a Firestore database. Although Firestore has excellent SDKs, they were unable to handle anything prior to the 8.-year-old.NET Framework 4.6.2. Google could have been able to use a TCP connection to access a conventional relational database, but didn’t want to be restricted in Google cloud options for cloud services and tools. Building a real-time web application with MySQL instead of Firestore, which is built from the ground up to push data to the browser in real-time, is obviously far less viable.

Difficult deployment process: You may wish to add new features and cloud integrations, but updating your on-device software may be challenging due to various constraints. Google cloud had to use a USB stick to manually install every version of game while it was being developed because third-party developers. Testing, deploying, and shipping new versions of your code is slowed down by this type of restriction, which is never good. In a contemporary, adaptable cloud platform, adding new features is far simpler.

In essence, discovered that utilizing contemporary cloud services in an unpredictable legacy setting was difficult.

Flipper-ing the script

Initially, it seemed impossible to incorporate all of the services desired into the code that would operate on the pinball machine. However, what if there was an alternative? What if it gave the pinball machine a single simple integration and transformed it into a service? They might then arrange the outcomes in a contemporary cloud environment and have it send a message each time something occurred in the game.

Google cloud concluded that Pub/Sub would be a great approach to accomplish this. It offered a simple method of transferring data to the cloud via a single interface. It was really a simple HTTP POST with any message format desired.Image credit to Google cloud

It created a unique Pub/Sub messaging mechanism to accomplish this. To manage authentication and message delivery via the REST API, created a lightweight Pub/Sub framework just for the pinball machine. This made it incredibly simple to submit events anytime a player struck a target, fired a ball, or even pressed a flipper button. Visit GitHub to view a condensed version of that code!

Google cloud team processed these events in real time on the cloud side by using numerous Cloud Run subscribers. Additionally, stored data and powered visualizations using Firestore.

Jackpot! Benefits of the cloud

There were many benefits of pushing integration complexity into the cloud:

One interface: Authentication alone might be a blog entry in and of itself, so creating own Pub/Sub client was no easy feat. But when it was finished, it was finished! After it was operational, Google could concentrate on employing whichever contemporary client libraries and tools desired to process every event in the cloud.

Real-time updates: At Google Cloud Next, assisted users in creating custom Cloud Run services that can process pinball machine, send messages back to the machine, and receive them. You could theoretically alter the game while a friend was playing it because it took less than a minute to build and deploy these services!

Rich insights from data: In the end, they had a detailed record of every event that took place throughout a game. Playtest-based scoring adjustments and development-related troubleshooting were greatly aided by this.

Leaping ahead

The next version of Backlogged Pinball is already in the works, and it will include features hadn’t initially thought of. For instance, its’re including AI-driven Gameplay and player-style-based recommendations. Instead of struggling with dependencies on a historical system, nearly all of the work will be done in a contemporary cloud environment because of this adaptable cloud-based design.

Furthermore, any limited environment can benefit from the lessonsz learnt from this project. You can overcome the constraints of your environment and realize the full potential of the cloud by utilizing Pub/Sub messaging and embracing a cloud-first mindset, regardless matter whether it’s an embedded system, an Internet of Things device, or an outdated server running older software.

Olibr’s Expert Answer: InnoDB and MyISAM are two commonly used storage engines in MySQL. InnoDB is transactional and ACID-compliant, supporting features like foreign keys, row-level locking, and crash recovery. MyISAM, on the other hand, is non-transactional, faster for read-heavy workloads, but lacks features such as foreign keys and crash recovery.

3. What are indexes in MySQL, and how do they improve query performance?

Olibr’s Expert Answer: Indexes are data structures that improve query performance by allowing faster retrieval of rows based on indexed columns. They reduce the number of rows MySQL must examine when executing queries, speeding up data retrieval operations, and optimizing database performance.

4. Explain the difference between INNER JOIN and LEFT JOIN in MySQL.

Olibr’s Expert Answer: INNER JOIN and LEFT JOIN are SQL join types used to retrieve data from multiple tables. INNER JOIN returns rows where there is a match in both tables based on the join condition. LEFT JOIN returns all rows from the left table and matching rows from the right table, with NULL values for non-matching rows in the right table.

5. What are the advantages of using stored procedures in MySQL?

Olibr’s Expert Answer: Stored procedures in MySQL offer several advantages, including improved performance due to reduced network traffic, enhanced security by encapsulating SQL logic, code reusability across applications, easier maintenance and updates, and centralized database logic execution.

Conclusion

By mastering these MySQL interview questions and understanding Olibr’s expert answers, candidates can demonstrate their proficiency in MySQL database management, query optimization, and best practices during interviews. Olibr’s insights provide valuable guidance for preparing effectively, showcasing skills, and unlocking success in MySQL-related roles.

i wanted to try out using SQL for managing my work data because Python is a real bitch about putting different data types into one table most of the time, but so far it is so frustrating i'm close to tearing every object around me to shreds. every step of the way, i run into some new problems. and stackexchange is mostly unhelpful because they just go "it's simple just execute these 20 commands" WHERE. BITCH WHERE. cmd doesn't know what "mysql" is. mysql command line doesn't have "global" defined WHAT ARE YOU TALKING ABOUT TELL MEEEEEEEEE I'M SHTUPID

Scaling Secrets: The Architecture That Made 1 Million Users Possible.

Picture this: you launch an app, thinking it'll be a cool side project. But then, something unexpected happens—boom, a viral post, a feature takes off, and suddenly, you're not just handling a few hundred users… you're scrambling to manage 1 million.

It’s every startup’s dream, right? But when reality hits, it's more like a nightmare.

How do you keep your app running smoothly as it rockets to 1 million users? Is there a magic formula, or are you just riding on sheer luck? Spoiler: It’s the architecture—the unsung hero of scaling that most people never talk about.

Let’s dive into the secret sauce that makes all that user growth possible without your app crumbling into oblivion. Trust us, it’s not as simple as throwing money at servers. This is how the pros do it.

Choosing the Right Tech Stack: Building a House with Strong Foundations Okay, first things first: Tech stack matters. Like, a lot. You wouldn't try to build a skyscraper on sand, right? So why would you choose a tech stack that can't handle the weight of millions of users?

The magic happens when you combine the right tools, like a killer backend framework and a database that grows with you.

Backend Frameworks like Node js or Go are the go-to for handling tons of requests. They’re built for speed and efficiency—perfect for a fast-growing app.

For databases, you’ve got to pick wisely. NoSQL (think MongoDB or Cassandra) can handle huge amounts of unstructured data, while SQL (like PostgreSQL or MySQL) is your best friend if you need relationships and transactions in your data.

Caching with tools like Redis or Memcached? A must. Speeding things up by storing frequently accessed data right where it’s needed is a game changer.

Pro Tip: Always choose a tech stack that can scale horizontally, meaning you can add more servers as you grow, rather than upgrading a single, overworked one. (That’s vertical scaling—it's not ideal.)

Horizontal Scaling: More Servers, More Power, No Drama When your app starts attracting millions of users, you’ll quickly discover that vertical scaling—just adding more juice to a single server—doesn’t cut it. It’s like trying to get 10,000 people into a restaurant that only has 10 tables.

Horizontal scaling is where the magic happens. You add more servers to handle the load. It’s like spreading out your resources instead of cramming them into one spot.

Here’s how it works:

A load balancer (like HAProxy or Nginx) distributes the traffic evenly across servers, so no single server crashes from a flood of traffic.

With auto-scaling, your system can automatically add or remove servers based on demand. Got a huge spike in traffic? The system scales up. A quieter day? It scales down. Simple, smart, and flexible.

Outcome: Your app keeps running fast, even when things get crazy.

Sharding: Breaking Up Your Database So It Doesn’t Break You As your app grows, your database grows with it. But here’s the thing: Databases can’t just keep growing forever. At some point, they get too big to handle efficiently. So, how do you keep things running smoothly?

Enter sharding. Think of it like slicing a giant cake into manageable pieces. Instead of storing everything on one massive database, you break it down into smaller, more manageable chunks (called shards).

This way, no one shard gets overloaded. Requests are distributed across multiple database instances, which dramatically speeds things up.

Pro Tip: You can shard your database by horizontal partitioning (e.g., splitting it based on user regions or data types). This reduces database bottlenecks and keeps everything running smoothly.

Microservices: Because One Big App Is a Disaster Waiting to Happen Remember when apps used to be monolithic? Everything was packed into one giant codebase, and you couldn’t change anything without breaking the whole thing. It was a developer's nightmare, and it didn’t scale.

Instead of trying to make one giant app work for everyone, microservices break your app down into smaller, independent pieces. Each microservice does one thing really well, and you can scale those individual pieces separately.

For example, you can have separate services for:

User authentication

Payments

Notifications

Search

These can all run independently, and you can scale them up or down based on specific needs. No more overloading the entire app when just one piece needs more power.

Pro Tip: Use API gateways to handle communication between your microservices and route traffic where it needs to go. This keeps things organized and efficient.

CDNs: Because Speed Kills (In a Good Way) Speed is everything when you’ve got millions of users. Think about it: If your app’s taking more than a few seconds to load, users will bounce faster than you can say “goodbye.” So, how do you speed things up? The answer is simple: CDNs (Content Delivery Networks).

A CDN caches static content (like images, CSS files, and scripts) on multiple servers around the world. So, no matter where your users are, they’re always getting content from the closest server to them. Faster load times = happy users.

Pro Tip: Use Cloudflare or AWS CloudFront to distribute your static assets. This also reduces the load on your primary servers, leaving more resources for dynamic content.

Asynchronous Processing: Don’t Make Your Users Wait Nobody likes waiting. So when your app has background tasks (like sending emails, processing payments, or generating reports), don’t make your users wait around for them to finish.

Instead of handling these tasks synchronously (i.e., right during the user’s request), you process them asynchronously in the background.

This keeps your app responsive, letting users go about their business while those tasks run in the background.

How it works:

Use message queues (like RabbitMQ or Kafka) to send tasks to a queue.

Then, set up worker processes to pull tasks from the queue and process them at their own pace.

Outcome: Your app is faster and more responsive, which means a better experience for your users.

Proactive Monitoring: Because You Don’t Want to Be Caught Off Guard Here’s a brutal truth: things will break. It’s not if—it’s when. The key is to catch issues early before they cause a domino effect of failures.

Proactive monitoring with tools like Prometheus, Datadog, or New Relic keeps an eye on your app’s health in real-time. You’ll get alerts for anything that seems off—like a spike in response times or a server that’s about to crash—so you can fix it before it affects users.

Pro Tip: Set up alerting systems that notify you about potential issues (e.g., high traffic, slow queries). This lets you scale or fix things on the fly.

Failover and Redundancy: Plan for the Worst, Hope for the Best A million users means that even a single point of failure can cause major issues. That’s why you need redundancy and failover built into your architecture. Think of it like a safety net.

Have multiple data centers in different locations.

Replicate your databases and services to ensure that if one fails, the others can pick up the slack.

Use health checks to automatically route traffic to healthy servers.

Outcome: Your app stays up and running 24/7—even if something goes wrong. Users stay happy, and you sleep easy.

The Million-User Blueprint: Scale Smart, Scale Right Getting to 1 million users isn’t magic. It’s a combination of smart design, the right tech stack, and the architecture that lets you scale gracefully. Horizontal scaling, microservices, sharding, CDNs, and asynchronous processing are just a few of the building blocks that power apps with massive user bases.

So, the next time your app goes viral, don’t panic. Instead, focus on scaling smart with these strategies. Because handling 1 million users doesn’t just require hard work—it requires building the right foundation from the start.

Ready to scale? Let’s get building! 🚀

AEserver UAE - .ae Domains & Web Hosting Provider

AEserver is not just a hosting provider. It is the mainstay of the UAE's digital infrastructure, focused on entrepreneurs, startups, international brands, and ambitious technology projects that need stable, predictable results rather than abstract "support." Since 2005, AEserver has been providing hosting in the UAE with legal registration, DED license, full localization and SLA, where uptime is kept at 99.9%. And all this is not on paper.

The company's data center is located in Dubai. Not just anywhere, but right in the key technological zone of the region, closer to the customer, closer to the user, closer to the traffic entry point. This means fewer delays, higher throughput, and more control. Inside there are dedicated servers with NVMe, VPS virtual machines with custom configuration, cloud solutions with vertical scaling and fault tolerance. All servers are monitored, with automatic updates, overheating protection, and backup power supplies.

Security? Yes, at the infrastructure level: BitNinja, SSL certificates, firewall, white-list IP, database encryption, two-factor authentication. Access control and rights settings via SSH/SFTP are implemented flexibly. Control panels are supported: cPanel, DirectAdmin, ISPmanager. Redis, Memcached, and Varnish caching systems are enabled by default on advanced plans. For working with content — LAMP/LEMP stacks, Apache, NGINX, PHP-FPM, MySQL, MariaDB. And all this is easily connected to a CMS, including WordPress.

In AEserver, you can register a domain in the zone.ae, get a free domain when activating the tariff, connect business mail, transfer the site from another hosting without downtime. There is multisite support, tariff plans for different types of workloads, and, importantly, flexible billing with an Islamic payment method and support for cryptocurrencies. Support works 24/7 through the ticket system — quickly, to the point, with attention to the technical essence.

AEserver is more than a web hosting service. This is a service with a human face and iron discipline in the server room. This is an opportunity to scale a startup in Dubai, comply with legal requirements, work legally and stably, without losing either speed or flexibility. This is where IT becomes a pillar of business, not a headache.
