Microservices in Spring Boot

When I first heard about microservices, it felt a bit overwhelming. So many services, communication between them, service registry, security—it sounded like a lot to handle.

But once I started using Spring Boot, things began to make sense.

Getting Started Felt Easy

Spring Boot made it really simple to start building small services. I didn’t have to worry about setting up servers or writing too much configuration. Just a few annotations and things started working! That felt very satisfying.

With microservices, I liked how I could break one big application into smaller parts. Each part (or service) had its own job—like handling users, processing orders, or managing inventory.

If one part failed, the others still worked. That gave me more control and helped me focus better on one feature at a time.

One thing that excited me was Eureka. I didn’t need to hardcode service URLs anymore. Services would register themselves to Eureka, and they could find each other automatically.

It felt like magic when one service called another just by its name!

I used Feign Client to call one service from another. It felt very clean and simple. No need to write complicated REST code—just create an interface and call methods like normal Java code.

At first, securing each service felt tough. But then I learned how to use Spring Security with JWT tokens. Once I got it working, I felt proud because I knew my services were protected and only the right users could access them.

Final Thoughts

Honestly, working with microservices in Spring Boot felt like a journey. At first, I was confused, but step by step, it all became clear. It’s not always easy, but when things work, it feels great.

If you're learning microservices, my advice is: start small, keep learning, and don’t give up. Spring Boot will help you a lot along the way!
