Microservices architecture is a new way of building software that breaks an app up into many loosely connected services that can be run on their own. Each microservice has its own business tasks and only talks to other services through well-defined APIs, like gRPC or REST. This means it doesn’t need other services as much. This structure allows different services to be built and grown independently, which makes them more adaptable, scalable, and able to handle errors.

Microservices often use a tech stack that includes messaging systems like Kafka to send and receive messages at different times. They use containerisation systems like Docker, orchestration tools like Kubernetes, and frameworks like Spring Boot to build services. Companies also use cloud services like AWS and Azure and distributed caching solutions like Redis and GridGain to get very low latency, high throughput, and easy horizontal scalability.

Using microservices in real life is easier with strong CI/CD pipelines, automated testing frameworks, and ways to find and fix bugs. All of these things work together to make the system more dependable, better able to handle problems, and faster at getting things done. Because of this mix, microservices are a good choice for large business apps that need to be available all the time, easy to maintain, and flexible.
