Audit Logging in Java Microservices: Techniques and Compliance Tips

Audit Logging in Java Microservices: Techniques and Compliance Tips

In the era of distributed systems, microservices introduce agility and scalability — but they also dramatically increase complexity in tracking user actions and system changes. Audit logging plays a crucial role in ensuring traceability, accountability, and compliance with regulations such as GDPR, HIPAA, PCI-DSS, SOX, and ISO 27001. In this Read more

API Rate Limiting & Throttling in Spring Boot with Bucket4j

API Rate Limiting & Throttling in Spring Boot with Bucket4j

As modern systems continue to embrace microservices, public APIs, and high-volume traffic, controlling how consumers access APIs becomes critical. Without proper rate limiting, even a single misbehaving client can overwhelm your application—leading to degraded performance, increased latency, and potential downtime. Rate limiting and throttling safeguard your APIs by controlling the Read more

Integrating AWS SQS and SNS in Java Applications for Reliable Messaging

Integrating AWS SQS and SNS in Java Applications for Reliable Messaging

Modern distributed systems rely heavily on asynchronous communication to maintain resilience, scalability, and fault isolation. AWS offers two widely adopted managed messaging services—Amazon Simple Queue Service (SQS) and Amazon Simple Notification Service (SNS)—that simplify building event-driven architectures in Java applications. SNS enables pub/sub messaging with multiple subscribers, while SQS provides 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
