Setting Up a Production-Grade Kubernetes Cluster
Kubernetes is a powerful system for managing containerized applications, but setting up a production-grade Kubernetes cluster involves more than just running kubeadm init. This article walks you through the key considerations and steps to deploy a secure, scalable, and maintainable cluster that’s ready for real-world workloads. 1. Define Your Requirements Before provisioning anything, you must…

Understanding the CAP Theorem: Consistency, Availability, and Partition Tolerance in Distributed Systems
Distributed systems are designed to be scalable, resilient, and efficient. However, building such systems often involves trade-offs. One of the most important theoretical frameworks for understanding these trade-offs is the CAP Theorem. In this article, we will explore what the CAP Theorem is, what each of its components means, and how real-world systems navigate the…

What Is Reactive Spring Boot?
Reactive Spring Boot (via Spring WebFlux) is a non-blocking, asynchronous programming model built on Project Reactor. It supports event-driven execution, making it ideal for handling thousands of concurrent requests without being limited by traditional thread-per-request constraints. It is different from the traditional Spring MVC (which is synchronous/blocking and servlet-based). Key Benefits of Reactive Spring Boot…

Why Java Garbage Collection Becomes Slow When Memory Is Paged to Disk
When Memory Is Paged to Disk Paging occurs when the operating system runs out of physical memory (RAM) and uses a portion of the disk (swap space) to simulate additional memory. This happens under the following conditions: How to Prevent Paging and Slow GC Conclusion Garbage collection slows significantly when memory is paged to disk…

Active Active Deployment
Part-1 Scalable Architectures Series Active-Active deployment architecture, also known as load balancing or horizontal scaling, involves deploying multiple instances of an application or service, with each instance actively handling requests. This approach provides high availability, scalability, and fault tolerance. However, accomplishing an Active-Active deployment architecture poses several challenges: Biggest Challenges Architectural Changes Needed at the…
