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…

Building Multi-Tenant Applications with Spring Boot

Building Multi-Tenant Applications with Spring Boot

As businesses scale and serve multiple customers, building multi-tenant applications becomes a core architectural need. A multi-tenant application is designed to serve more than one client (tenant), while maintaining data isolation, security, and performance efficiency. In this blog, we explore the strategies and implementation techniques to build multi-tenant applications using Read more…

A Guide to Resilience4j in Spring Boot for Fault-Tolerant Systems

A Guide to Resilience4j in Spring Boot for Fault-Tolerant Systems

Modern distributed systems must be resilient in the face of network failures, service downtime, and unpredictable latencies. As microservices architecture becomes the standard, building systems that can gracefully handle such failures is not just a feature—it’s a requirement. Resilience4j, a lightweight fault-tolerance library inspired by Netflix Hystrix, is designed for Read more…

Building Event-Driven Architectures Using Spring Boot and Kafka

Building Event-Driven Architectures Using Spring Boot and Kafka

As applications scale in complexity and volume, traditional request-response models often fall short in terms of responsiveness, decoupling, and scalability. Event-driven architecture (EDA) has emerged as a powerful paradigm to address these challenges, enabling reactive, resilient, and loosely coupled systems. In this blog, we will explore how to build event-driven Read more…
