If you're aiming to reduce time-to-market and enhance software performance, hiring DevOps professionals is no longer optional—it's strategic.

Understanding DevOps and Its Value

DevOps is a set of practices that merges software development (Dev) and IT operations (Ops). The goal is simple: shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business goals. When you hire DevOps developers, you're investing in automation, continuous integration and deployment (CI/CD), infrastructure as code (IaC), and monitoring—all critical for scaling efficiently.

Why Businesses Need to Hire DevOps Developers

Organizations that hire DevOps developers gain a competitive edge through streamlined workflows and fewer manual errors. Whether you're a startup or an enterprise, these professionals help build robust CI/CD pipelines, enforce code quality standards, and integrate tools like Docker, Kubernetes, Jenkins, and Terraform.

Software Development—everything you need to know indicates that companies embracing DevOps are 46x more likely to deploy code faster and 96x quicker at recovering from failures than those that don’t. The ROI on DevOps is clear: speed, stability, and security.

What DevOps Developers Actually Do

When you hire DevOps developers, you’re not just bringing on someone to write scripts—they architect entire systems. These engineers are responsible for configuring servers, automating processes, and ensuring scalability across cloud platforms like AWS, Azure, or GCP. Their job is to enable development teams to push code that’s stable and production-ready, faster.

A Custom Software Development Company that integrates DevOps in its delivery model tends to produce higher-quality apps with better user satisfaction and retention.

Kubernetes vs. Traditional Infrastructure: Why Clusters and Pods Win

In today’s fast-paced digital landscape, agility, scalability, and reliability are not just nice-to-haves—they’re necessities. Traditional infrastructure, once the backbone of enterprise computing, is increasingly being replaced by cloud-native solutions. At the forefront of this transformation is Kubernetes, an open-source container orchestration platform that has become the gold standard for managing containerized applications.

But what makes Kubernetes a superior choice compared to traditional infrastructure? In this article, we’ll dive deep into the core differences, and explain why clusters and pods are redefining modern application deployment and operations.

Understanding the Fundamentals

Before drawing comparisons, it’s important to clarify what we mean by each term:

Traditional Infrastructure

This refers to monolithic, VM-based environments typically managed through manual or semi-automated processes. Applications are deployed on fixed servers or VMs, often with tight coupling between hardware and software layers.

Kubernetes

Kubernetes abstracts away infrastructure by using clusters (groups of nodes) to run pods (the smallest deployable units of computing). It automates deployment, scaling, and operations of application containers across clusters of machines.

Key Comparisons: Kubernetes vs Traditional Infrastructure

Feature

Traditional Infrastructure

Kubernetes

Scalability

Manual scaling of VMs; slow and error-prone

Auto-scaling of pods and nodes based on load

Resource Utilization

Inefficient due to over-provisioning

Efficient bin-packing of containers

Deployment Speed

Slow and manual (e.g., SSH into servers)

Declarative deployments via YAML and CI/CD

Fault Tolerance

Rigid failover; high risk of downtime

Self-healing, with automatic pod restarts and rescheduling

Infrastructure Abstraction

Tightly coupled; app knows about the environment

Decoupled; Kubernetes abstracts compute, network, and storage

Operational Overhead

High; requires manual configuration, patching

Low; centralized, automated management

Portability

Limited; hard to migrate across environments

High; deploy to any Kubernetes cluster (cloud, on-prem, hybrid)

Why Clusters and Pods Win

1. Decoupled Architecture

Traditional infrastructure often binds application logic tightly to specific servers or environments. Kubernetes promotes microservices and containers, isolating app components into pods. These can run anywhere without knowing the underlying system details.

2. Dynamic Scaling and Scheduling

In a Kubernetes cluster, pods can scale automatically based on real-time demand. The Horizontal Pod Autoscaler (HPA) and Cluster Autoscaler help dynamically adjust resources—unthinkable in most traditional setups.

3. Resilience and Self-Healing

Kubernetes watches your workloads continuously. If a pod crashes or a node fails, the system automatically reschedules the workload on healthy nodes. This built-in self-healing drastically reduces operational overhead and downtime.

4. Faster, Safer Deployments

With declarative configurations and GitOps workflows, teams can deploy with speed and confidence. Rollbacks, canary deployments, and blue/green strategies are natively supported—streamlining what’s often a risky manual process in traditional environments.

5. Unified Management Across Environments

Whether you're deploying to AWS, Azure, GCP, or on-premises, Kubernetes provides a consistent API and toolchain. No more re-engineering apps for each environment—write once, run anywhere.

Addressing Common Concerns

“Kubernetes is too complex.”

Yes, Kubernetes has a learning curve. But its complexity replaces operational chaos with standardized automation. Tools like Helm, ArgoCD, and managed services (e.g., GKE, EKS, AKS) help simplify the onboarding process.

“Traditional infra is more secure.”

Security in traditional environments often depends on network perimeter controls. Kubernetes promotes zero trust principles, pod-level isolation, and RBAC, and integrates with service meshes like Istio for granular security policies.

Real-World Impact

Companies like Spotify, Shopify, and Airbnb have migrated from legacy infrastructure to Kubernetes to:

Reduce infrastructure costs through efficient resource utilization

Accelerate development cycles with DevOps and CI/CD

Enhance reliability through self-healing workloads

Enable multi-cloud strategies and avoid vendor lock-in

Final Thoughts

Kubernetes is more than a trend—it’s a foundational shift in how software is built, deployed, and operated. While traditional infrastructure served its purpose in a pre-cloud world, it can’t match the agility and scalability that Kubernetes offers today.

Clusters and pods don’t just win—they change the game.

As organizations continue to scale containerized workloads across hybrid cloud environments, Red Hat OpenShift Container Storage (OCS) stands out as a critical component for managing data services within OpenShift clusters—whether on-premises or in the cloud.

🔧 What makes OCS powerful?

At the heart of OCS are three main operators that streamline storage automation:

OCS Operator – Acts as the meta-operator, orchestrating everything for a supported and reliable deployment.

Rook-Ceph Operator – Manages block, file, and object storage across environments.

NooBaa Operator – Enables the Multicloud Object Gateway for seamless object storage management.

🏗️ Deployment Flexibility: Internal vs. External

1️⃣ Internal Deployment

Storage services run inside the OpenShift cluster.

Ideal for smaller or dynamic workloads.

Two modes:

Simple: Co-resident with apps—great for unclear storage needs.

Optimized: Dedicated infra nodes—best when storage needs are well defined.

2️⃣ External Deployment

Leverages an external Ceph cluster to serve multiple OpenShift clusters.

Perfect for large-scale environments or when SRE/storage teams manage infrastructure independently.

🧩 Node Roles in OCS

Master Nodes – Kubernetes API and orchestration.

Infra Nodes – Logging, monitoring, and registry services.

Worker Nodes – Run both applications and OCS services (require local/portable storage).

Whether you're building for scale, resilience, or multi-cloud, OCS provides the flexibility and control your architecture demands.

📌 Curious about how to design the right OpenShift storage strategy for your org? Let’s connect and discuss how we’re helping customers with optimized OpenShift + Ceph deployments at HawkStack Technologies.

Measuring ROI in an AI Proof of Concept

Return on investment (ROI) guides organizations in deciding whether new initiatives justify resources. With an ai proof of concept, the stakes often feel higher—machine learning models, specialized data sets, and new infrastructure can rack up costs. Yet success can yield major wins, from operational gains to deeper user engagement. This blog explores how to systematically measure ROI in AI pilot projects and ensure those insights translate into more confident, data-driven expansions.

1. Defining Success Indicators

Cost-Reduction Metrics: E.g., “15% decrease in manual review time per day.”

Performance Upgrades: E.g., “Automated suggestions improved accuracy by 30%.”

User Engagement: E.g., “Chatbot usage soared by 40% after launch.”

Clear definitions let you quantify how the pilot aligns with strategic goals. If none of the metrics show improvement, the pilot might need rethinking.

2. Cost Components

Data Preparation: Labeling, cleaning, or merging data from scattered sources.

Model Development: ML engineering overhead—like CPU/GPU usage, specialized data scientists, or dev tools.

Pilot Deployment: Docker, Kubernetes, or cloud hosting charges.

Maintenance: Fixes, updates, and model re-training if performance drifts.

Tracking these helps you isolate each expense, forming a robust cost baseline for your ROI calculations.

3. Quantifying Benefits

Efficiency Gains: Did the pilot reduce manual steps? For instance, a helpdesk AI might cut average resolution time from 12 minutes to 6 minutes, saving labor hours.

Revenue Uplift: In some cases, a well-targeted AI pilot—like product recommendations—may boost cross-sales or conversions.

Quality Improvements: If AI-led inspection or analytics yields fewer defects or better forecasts, the resulting cost avoidance translates to real business value.

While intangible benefits like brand innovation or team morale matter, tangible metrics usually take precedence in ROI justification.

4. Data-Driven Approaches to ROI Tracking

4.1 A/B Testing Compare user interactions or processes in an AI pilot group vs. a control group. For example, half your site visitors see the AI-driven feature, half do not. Differences in behavior or outcomes highlight pilot benefits.

4.2 Real-Time Dashboards Visualizing cost usage, time saved, or user uptake as the pilot runs ensures immediate feedback. If metrics stall, you can adapt quickly—like adjusting model hyperparameters or focusing on new data sets.

4.3 Post-Pilot Analysis After the pilot, compile key stats into a final report: cost savings, success rates, or user opinions. This summary shapes the argument for further expansions or more advanced AI features.

5. Bridging the Gap Between Pilot and Full-Scale Implementation

Refine the Model: If the pilot’s accuracy was borderline acceptable, further data or re-training might close the gap for enterprise usage.

Enhance Architecture: For large-scale usage, add better DevOps integration or advanced orchestration with microservices.

Stakeholder Buy-In: Present the pilot’s ROI. If a chatbot saved 200 staff-hours monthly, scaling across more teams multiplies that advantage.

6. Potential Challenges in ROI Analysis

Attribution Issues: Distinguishing which gains come directly from the AI pilot vs. outside factors like seasonal demand spikes.

Overlapping Initiatives: If multiple transformations happen at once, it may be tough to isolate the pilot’s contribution.

Long-Term vs. Short-Term Gains: A short pilot might show minimal immediate gains, but set the foundation for bigger future returns.

7. Finalizing ROI-Focused Recommendations

Document Everything: Each cost item, from labeling hours to pipeline integration, ensures transparent budgeting.

Emphasize Quick Wins: Even small improvements can encourage broader stakeholder acceptance.

Propose Next Steps: If ROI is positive, highlight immediate expansions or features that could amplify results.

Conclusion

Calculating ROI for an ai proof of concept involves analyzing cost inputs meticulously against measurable improvements. By zeroing in on efficiency, accuracy, or revenue metrics, you can gauge the pilot’s tangible value. A well-structured ROI evaluation not only justifies the pilot’s budget but provides a roadmap for scaling AI across the enterprise—where real transformation, market competitiveness, and sustainable growth are realized. With data-driven ROI insights, your organization can confidently move from pilot success to broad-scale AI adoption.

The Future of Load Balancing: Trends and Innovations in Application Load Balancer

The future of load balancing is rapidly evolving with advancements in technology, particularly in the realm of application load balancers (ALBs). As businesses increasingly shift to cloud-native architectures and microservices, ALBs are becoming more crucial in ensuring efficient traffic distribution across applications. Innovations such as AI-powered load balancing, real-time traffic analytics, and integration with containerized environments like Kubernetes are enhancing the scalability and performance of ALBs. Additionally, the rise of edge computing is pushing ALBs closer to end-users, reducing latency and improving overall user experience. As security concerns grow, ALBs are also incorporating advanced threat detection and DDoS protection features. These trends promise a more reliable, efficient, and secure approach to managing application traffic in the future.

What is an Application Load Balancer (ALB) and How Does It Work?

Application Load Balancer (ALB) is a cloud-based service designed to distribute incoming network traffic across multiple servers, ensuring optimal performance and high availability of applications. ALBs operate at the application layer (Layer 7) of the OSI model, which means they can make intelligent routing decisions based on the content of the request, such as URL, host headers, or HTTP methods. This differs from traditional load balancers that operate at the network layer. ALBs offer more sophisticated features for modern web applications, making them essential for scalable, highly available cloud environments.

Key Features of Application Load Balancer (ALB)

ALBs provide several features that make them highly suitable for distributed applications:

Content-Based Routing: ALBs can route traffic based on the URL path, host headers, or HTTP methods, enabling fine-grained control over the distribution of requests.

SSL Termination: ALBs can offload SSL termination, decrypting HTTPS requests before forwarding them to backend servers, thus improving performance.

Auto Scaling Integration: ALBs integrate seamlessly with auto-scaling groups, ensuring that traffic is evenly distributed across new and existing resources.

WebSocket Support: ALBs support WebSocket connections, making them ideal for applications requiring real-time, two-way communication.

Advantages of Using an Application Load Balancer in Cloud Environments

Application Load Balancers offer several benefits, particularly in cloud environments:

Improved Availability and Fault Tolerance: ALBs distribute traffic to healthy instances, ensuring high availability even if some backend servers fail.

Better Performance and Latency Optimization: By routing traffic based on specific parameters, ALBs can reduce response times and ensure efficient resource utilization.

Scalability: With ALBs, applications can scale horizontally by adding or removing instances without affecting performance, making them ideal for elastic cloud environments like AWS and Azure.

Security Enhancements: ALBs provide SSL termination, reducing the load on backend servers and offering better security for user data during transmission.

Application Load Balancer vs. Classic Load Balancer: Which One Should You Choose?

When choosing a load balancer for your application, understanding the difference between an Application Load Balancer (ALB) and a Classic Load Balancer (CLB) is crucial:

Layer 7 vs. Layer 4: ALBs operate at Layer 7 (application layer), while CLBs work at Layer 4 (transport layer). ALBs offer more sophisticated routing capabilities, whereas CLBs are simpler and more suitable for TCP/UDP-based applications.

Routing Based on Content: ALBs can route traffic based on URLs, headers, or query parameters, whereas CLBs route traffic at the IP level.

Support for Modern Web Apps: ALBs are designed to support modern web application architectures, including microservices and containerized apps, while CLBs are more suited for monolithic architectures.

SSL Offloading: ALBs offer SSL offloading, whereas CLBs only support SSL pass-through.

How to Set Up an Application Load Balancer on AWS?

Setting up an ALB on AWS involves several steps:

Step 1: Create a Load Balancer: Begin by creating an Application Load Balancer in the AWS Management Console. Choose a name, select the VPC, and configure listeners (typically HTTP/HTTPS).

Step 2: Configure Target Groups: Define target groups that represent the backend services or instances that will handle the requests. Configure health checks to ensure traffic is only sent to healthy targets.

Step 3: Define Routing Rules: Configure routing rules based on URL paths, hostnames, or HTTP methods. You can create multiple rules to direct traffic to different target groups based on incoming request details.

Step 4: Configure Security: Enable SSL certificates for secure communication and set up access control policies for your load balancer to protect against unwanted traffic.

Step 5: Test and Monitor: Once the ALB is set up, monitor its performance via AWS CloudWatch to ensure it is handling traffic as expected.

Common Use Cases for Application Load Balancer

Application Load Balancers are suitable for various use cases, including:

Microservices Architectures: ALBs are well-suited for routing traffic to different microservices based on specific API routes or URLs.

Web Applications: ALBs can efficiently handle HTTP/HTTPS traffic for websites, ensuring high availability and minimal latency.

Containerized Applications: In environments like AWS ECS or Kubernetes, ALBs can distribute traffic to containerized instances, allowing seamless scaling.

Real-Time Applications: ALBs are ideal for applications that rely on WebSockets or require low-latency responses, such as online gaming or live chat systems.

Troubleshooting Common Issues with Application Load Balancer

While ALBs offer powerful functionality, users may encounter issues that need troubleshooting:

Health Check Failures: Ensure that the health check settings (like path and response code) are correct. Misconfigured health checks can result in unhealthy targets.

SSL/TLS Configuration Issues: If SSL termination isn’t set up properly, users might experience errors or failed connections. Ensure SSL certificates are valid and correctly configured.

Routing Misconfigurations: Ensure that routing rules are properly defined, as incorrect routing can lead to traffic being sent to the wrong target.

Scaling Issues: If targets are not scaling properly, review auto-scaling group configurations to ensure they align with the ALB's scaling behavior.

Conclusion

Application Load Balancers are critical in optimizing the performance, availability, and scalability of modern web applications. By providing intelligent routing based on content, ALBs enable efficient handling of complex application architectures, such as microservices and containerized environments. Their ability to handle high volumes of traffic with low latency, integrate seamlessly with auto-scaling solutions, and enhance security makes them an invaluable tool for businesses looking to scale their operations efficiently. When setting up an ALB, it is essential to understand its key features, use cases, and best practices to maximize its potential. Whether deployed on AWS, Azure, or other cloud platforms, an Application Load Balancer ensures your applications remain responsive and available to users worldwide.

Pods in Kubernetes Explained: The Smallest Deployable Unit Demystified

As the foundation of Kubernetes architecture, Pods play a critical role in running containerized applications efficiently and reliably. If you're working with Kubernetes for container orchestration, understanding what a Pod is—and how it functions—is essential for mastering deployment, scaling, and management of modern microservices.

In this article, we’ll break down what a Kubernetes Pod is, how it works, why it's a fundamental concept, and how to use it effectively in real-world scenarios.

What Is a Pod in Kubernetes?

A Pod is the smallest deployable unit in Kubernetes. It encapsulates one or more containers, along with shared resources such as storage volumes, IP addresses, and configuration information.

Unlike traditional virtual machines or even standalone containers, Pods are designed to run tightly coupled container processes that must share resources and coordinate their execution closely.

Key Characteristics of Kubernetes Pods:

Each Pod has a unique IP address within the cluster.

Containers in a Pod share the same network namespace and storage volumes.

Pods are ephemeral—they can be created, destroyed, and rescheduled dynamically by Kubernetes.

Why Use Pods Instead of Individual Containers?

You might ask: why not just deploy containers directly?

Here’s why Kubernetes Pods are a better abstraction:

Grouping Logic: When multiple containers need to work together—such as a main app and a logging sidecar—they should be deployed together within a Pod.

Shared Lifecycle: Containers in a Pod start, stop, and restart together.

Simplified Networking: All containers in a Pod communicate via localhost, avoiding inter-container networking overhead.

This makes Pods ideal for implementing design patterns like sidecar containers, ambassador containers, and adapter containers.

Pod Architecture: What’s Inside a Pod?

A Pod includes:

One or More Containers: Typically Docker or containerd-based.

Storage Volumes: Shared data that persists across container restarts.

Network: Shared IP and port space, allowing containers to talk over localhost.

Metadata: Labels, annotations, and resource definitions.

Here’s an example YAML for a single-container Pod:

yaml

CopyEdit

apiVersion: v1

kind: Pod

metadata:

name: myapp-pod

spec:

containers:

- name: myapp-container

image: myapp:latest

ports:

- containerPort: 80

Pod Lifecycle Explained

Understanding the Pod lifecycle is essential for effective Kubernetes deployment and troubleshooting.

Pod phases include:

Pending: The Pod is accepted but not yet running.

Running: All containers are running as expected.

Succeeded: All containers have terminated successfully.

Failed: At least one container has terminated with an error.

Unknown: The Pod state can't be determined due to communication issues.

Kubernetes also uses Probes (readiness and liveness) to monitor and manage Pod health, allowing for automated restarts and intelligent traffic routing.

Single vs Multi-Container Pods

While most Pods run a single container, Kubernetes supports multi-container Pods, which are useful when containers need to:

Share local storage.

Communicate via localhost.

Operate in a tightly coupled manner (e.g., a log shipper running alongside an app).

Example use cases:

Sidecar pattern for logging or proxying.

Init containers for pre-start logic.

Adapter containers for API translation.

Multi-container Pods should be used sparingly and only when there’s a strong operational or architectural reason.

How Pods Fit into the Kubernetes Ecosystem

Pods are not deployed directly in most production environments. Instead, they're managed by higher-level Kubernetes objects like:

Deployments: For scalable, self-healing stateless apps.

StatefulSets: For stateful workloads like databases.

DaemonSets: For deploying a Pod to every node (e.g., logging agents).

Jobs and CronJobs: For batch or scheduled tasks.

These controllers manage Pod scheduling, replication, and failure recovery, simplifying operations and enabling Kubernetes auto-scaling and rolling updates.

Best Practices for Using Pods in Kubernetes

Use Labels Wisely: For organizing and selecting Pods via Services or Controllers.

Avoid Direct Pod Management: Always use Deployments or other controllers for production workloads.

Keep Pods Stateless: Use persistent storage or cloud-native databases when state is required.

Monitor Pod Health: Set up liveness and readiness probes.

Limit Resource Usage: Define resource requests and limits to avoid node overcommitment.

Final Thoughts

Kubernetes Pods are more than just containers—they are the fundamental building blocks of Kubernetes cluster deployments. Whether you're running a small microservice or scaling to thousands of containers, understanding how Pods work is essential for architecting reliable, scalable, and efficient applications in a Kubernetes-native environment.

By mastering Pods, you’re well on your way to leveraging the full power of Kubernetes container orchestration.

Class E IP Address Space Helps GKE Manage IPv4 Depletion

Using Class E IPv4 Address space to help GKE address IPv4 depletion problems. The need for private IPv4 addresses is growing along with the amount of services and apps hosted on Google Kubernetes Engine (GKE) (RFC 1918). The RFC1918 address space is becoming harder to come by for a lot of big businesses, which makes IP address depletion a problem that affects their application scalability.

This precise address depletion problem is resolved by IPv6, which offers a large number of addresses. But not every business or application is prepared for IPv6 just yet. You may continue to expand your company by entering the IPv4 address space (240.0.0.0/4), which can handle these problems.

Class E addresses (240.0.0.0/4) are set aside for future usage, as indicated in RFC 5735 and RFC 1112, as stated in Google VPC network acceptable IPv4 ranges; nevertheless, this does not preclude you from using them in certain situations today. Google will also provide tips for organizing and using GKE clusters with Class E.

Recognizing Class E addresses

IPv4 addresses

Some typical criticisms or misunderstandings about the use of Class E addresses are as follows:

Other Google services do not function with class E addresses. This is untrue. Class E addresses are included in the acceptable address ranges for IPV4 that Google Cloud VPC offers. Furthermore, private connection techniques using Class E addresses provide access to a large number of Google controlled services.

Communicating with services outside of Google (internet/on-premises/other clouds) is limited when using Class E addresses. False. You may use NAT or IP masquerading to convert Class E addresses to public or private IPv4 addresses in order to access destinations outside of Google Cloud, since Class E addresses are not routable and are not published over the internet or outside of Google Cloud. Furthermore,

a. Nowadays, a large number of operating systems support Class E addresses, with Microsoft Windows being the prominent exception.

b. Routing the addresses for usage in private DCs is supported by several on-premises suppliers (Cisco, Juniper, Arista).

There are scale and performance restrictions on Class E addresses. This is untrue. Regarding performance, there is no difference between the addresses and other address ranges used by Google Cloud. Agents can grow to accommodate a high number of connections without sacrificing speed, even with NAT/IP Masquerade.

Therefore, you may utilize Class E addresses for private usage inside Google Cloud VPCs, for both Compute Engine instances and Kubernetes pods/services in GKE, even though they are reserved for future use, not routable over the internet, and shouldn’t be publicized over the public internet.

Advantages

Class E IP Addresses

Despite these limitations, Class E addresses provide some benefits:

Large address space: Compared to standard RFC 1918 private addresses (around 17.9 million addresses vs. about 268.4 million addresses for it), Class E addresses provide a much bigger pool of IP addresses. Organizations experiencing IP address depletion will benefit from this abundance as it will enable them to expand their services and applications without being constrained by a finite amount of address space.

Growth and scalability: It addressing’s wide reach facilitates the simple scalability of services and apps on Google Cloud and GKE. IP address restrictions do not prevent you from deploying and growing your infrastructure, which promotes innovation and development even during times of high consumption.

Effective resource utilization: By using Class E addresses to enhance your IP address allocation procedures, you may reduce the possibility of address conflicts and contribute to the efficient use of IP resources. This results in reduced expenses and more efficient operations.

Future-proofing: Although it is not supported by all operating systems, its use is anticipated to rise in response to the growing need for IP addresses. You can future-proof your infrastructure scalability to enable company development for many years to come by adopting Class E early on.

Class E IP addresses

Things to be mindful of

Even though Class E IP addresses provide many advantages, there are a few crucial things to remember:

Compatibility with operating systems: At the moment, not all operating systems enable Class E addressing. Make sure your selected operating system and tools are compatible before putting Class E into practice.

Software and hardware for networking: Check to see whether your firewalls and routers (or any other third-party virtual appliance solutions running on Google Compute Engine) are capable of handling the addresses. Make sure any programs or software that use IP addresses are updated to support it as well.

Migration and transition: To ensure there are no interruptions while switching from RFC 1918 private addresses to it, meticulous preparation and execution are needed.

How Snap implemented Class E

Network IP management is becoming more difficult due to the growing use of microservices and containerization systems such as GKE, particularly by major clients like Snap. Snap’s finite supply of RFC1918 private IPv4 addresses was rapidly depleted with hundreds of thousands of pods deployed, impeding cluster scalability and necessitating a large amount of human work to release addresses.

Originally contemplating an IPv6 migration, Snap ultimately opted to deploy dual-stack GKE nodes and GKE pods (IPv6 + Class E IPv4) due to concerns over application readiness and compatibility. In addition to preventing IP fatigue, this approach gave Snap the scale of IP addresses it required for many years to accommodate future expansion and cut down on overhead. Furthermore, this technique was in line with Snap’s long-term plan to switch to IPv6.

Fresh clusters

Requirement

Construct native VPC clusters.

Steps

Make a subnetwork with supplementary ranges for services and pods, if desired. It range (240.0.0.0/4) has CIDRs that may be used in the secondary ranges.

When creating the cluster for the pod and services CIDR ranges, use the previously generated secondary ranges. This is an example of the user-managed secondary range assignment mechanism.

Setup IP masquerading to source network address translation (SNAT) to map the IP address of the underlying node to the source network address.

Migrating clusters

Requirement

The clusters need to be native to the VPC.

Steps

It is not possible to modify the cluster’s default pod IPv4 range. For more recent node pools that support Class E ranges, you may add pod ranges.

Workloads from earlier node pools may potentially be moved to newer node pools.

IPv4 Vs IPv6

Making the switch from IPv4 to IPv6 Class E

For enterprises experiencing IP depletion, switching to dual-stack clusters with the IPv4 and IPv6 addresses now is a wise strategic step. By increasing the pool of IP addresses that are accessible, it offers instant relief and permits expansion and scalability inside Google Cloud and GKE. Furthermore, implementing dual-stack clusters is an essential first step toward a more seamless IPv6-only transition.
