Implementing Cost-Aware Architecture on AWS: Tagging, Budgets, and Rightsizing

Implementing Cost-Aware Architecture on AWS: Tagging, Budgets, and Rightsizing

Managing cloud cost efficiency is no longer optional—it is a core architectural responsibility. As organizations move deeper into AWS, the focus shifts from simply deploying infrastructure to doing so in a cost-efficient, predictable, and measurable way. Cost-aware architecture ensures that engineering teams maintain visibility, accountability, and control over spending without Read more

Infrastructure as Code with Terraform: A Practical Guide for Java Developers

Introduction Infrastructure as Code (IaC) has transformed the way software is delivered. Instead of manually configuring servers and cloud services, developers can define their infrastructure in version‑controlled code, which makes deployments consistent, repeatable and auditable. Java developers, who often work on complex enterprise systems, can benefit tremendously from adopting IaC Read more

Role of Service Discovery in Microservices and How to Implement It with Eureka & Consul

Role of Service Discovery in Microservices and How to Implement It with Eureka & Consul

Introduction In modern cloud-native architectures, microservices have become the preferred style for building scalable, resilient, and independently deployable applications. However, this architectural model introduces dynamism and distribution: services may scale up or down, move between hosts or containers, and network addresses may change. In this context, service discovery emerges as Read more

How to Handle Schema Evolution in Microservices Communication

How to Handle Schema Evolution in Microservices Communication

In microservices architecture, services often evolve independently. Over time, this leads to changes in data contracts—commonly referred to as schema evolution. If not handled carefully, even minor schema changes can break inter-service communication, leading to data loss, runtime errors, or system outages. This article explores how to safely manage schema Read more

Implementing Distributed Tracing with OpenTelemetry in Java Microservices

Implementing Distributed Tracing with OpenTelemetry in Java Microservices

As microservices scale in complexity, debugging issues across multiple services becomes increasingly difficult. Traditional logging falls short when tracking a request across boundaries. This is where distributed tracing plays a crucial role. In this blog, we’ll explore how to implement distributed tracing in Java microservices using OpenTelemetry, an open-source observability Read more
