Microservices: Concepts

The microservice architecture is one of the most recent approaches to developing enterprise software applications. The concept of this style of software architecture has been discussed since 2011, and it has been establishing itself quickly.

concept of microservice is like :

The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.

Why microservices?

"Microservices is a phenomenon of building applications as a collection of multiple independent services which are loosely coupled".
It is nothing but decomposing the application into various modules which are independent of each other.
The primary advantage of Microservices is that the modules can be independently deployed. The team size of developers is very less (5-10),so that deployment is very fast.
There is no need of working with single technology for the entire application as like of monolithic kernel. Various technologies can be used to build the application and it makes developers to comfortably work as their interest.

In the same e-commerce example, with the use of microservices, the services can be divided into various groups and it makes the developer teams easy to maintain and deploy.
These microservices can communicate each other synchronously with REST API over http and asynchronously using message brokers like KAFKA,ACTIVEMQ etc.

JDK 25: The new features in Java 25

Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties. 2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...

what is circuit breaker in microservice

A circuit breaker is a design pattern used in microservice architecture to improve the resilience and fault tolerance of the system. In a microservice architecture, multiple services work together to deliver a business function. When a service is not available, the downstream services depending on it may start to fail as well, leading to a cascading failure. A circuit breaker helps prevent cascading failures by monitoring the status of the dependent services. If a dependent service is not responding, the circuit breaker trips and redirects the traffic to a fallback mechanism, such as a cache or a default response. The circuit breaker periodically attempts to reconnect to the dependent service, and once it's available, it resumes directing traffic to it. The circuit breaker pattern helps prevent failures from spreading across the system, improves the availability of the overall system, and can help reduce the load on dependent services.
