As developers, we understand the pain of configuration chaos — different settings scattered across various services, leading to maintenance nightmares. Settings like dependent services end points urls, Database configurations, application properties and profiles and environment related properties to name a few. It’s like juggling flaming swords blindfolded! But, here’s the…

Have you ever noticed that your application needs help from another application to fulfill certain requests? In a banking project I worked on, we faced a similar situation where one of our authentication components relied on another one to send out one-time passwords (OTP). The problem was that this other…

In the past, garbage collection was a bit of a performance bottleneck. It could cause your application to pause for a few milliseconds while the garbage collector was running. …

Why Distributed Tracing As a Web developer, you’ve likely encountered the challenges of managing a web application that handles everything in one place called monolith. While tracing incoming requests within such an application might have been relatively straightforward at the beginning, as time goes on and the codebase grows, it becomes increasingly difficult…

What is Custom Observability Custom observability refers to the practice of tailoring monitoring and instrumentation to specific needs and requirements of an application or system. It involves the strategic collection of metrics, logs, and traces to gain valuable insights into the system’s performance, health, and behavior. This is 3rd article in Spring boot Observability…

Monitoring plays a crucial role in ensuring the health and optimal performance of Spring Boot applications. It provides insights into the application’s behavior, identifies potential issues, and helps maintain high availability. In this article series on Spring observability, we will explore the importance of monitoring and how it can be…

What is Cyclic Barrier Imagine you and a group of friends decide to go on a hike together. You all start at the same time but decide to take different paths to reach a common meeting point. Along the way, you encounter various obstacles such as streams, hills, and dense forests. A cyclic barrier…

In a my previous project I worked on with an investment bank, we faced a challenge of efficiently limiting the number of threads executing a costly operation. We couldn’t use the `synchronized` keyword because it would restrict the method to be executed by only one thread, which would impact performance…

Why PerformanceMonitorInterceptor is important? In one of my previous project, we worked on a system that consisted of 25 microservices in the banking domain. The requirement was to handle a high load of 300 transactions per second (TPS). It was crucial for us to identify any performance issues early on, even in the development…
