Microservices Example Overview. Hello everyone. Good news, today we'll look at microservices through a code example. In the example, we will use Open Liberty. It is a lightweight framework that allows you to build fast and efficient cloud-native Java microservices. It provides you the live reload, so you have quick iteration with your development. It also starts up fast with a low memory footprint. Open Liberty implements Jakarta EE and MicroProfile. As you know, Jakarta EE, formerly known as Java EE, is an open-source Java platform for building enterprise applications. It provides you to use specifications for common services such as transaction management, security, and database access. The Jakarta specifications that Open Liberty implementations are Jakarta Context Dependency Injection, Jakarta Persistence, Jakarta Restful Web Services, Jakarta Security, Jakarta JSON Binding, Jakarta Bean Validation.
MicroProfile, introduced by Eclipse, is a modular set of technologies that are designed so that we can write cloud-native Java microservices. Cloud-native is a new term that has become popular recently. It's an industry-wide approach for developing and rapidly deploying applications to the cloud at scale. Cloud-native applications are designed around team-managed microservices and developed by using agile practices and continuous integration, continuous delivery to streamline deployment. There are a lot of vendors that provide cloud platforms, but open source and open standards are essential enablers for avoiding vendor lock-in. This is a fact that makes MicroProfile a strong and effective tool because it is open source. You can expect its code through this link. Okay, that's enough for the intro. Let's talk about our microservice project details. I'm going to make a simple citizen registry application using microservices architecture. It consists of two different services: Citizen Service and National Identification Number Service. Here, citizen service will communicate and get the citizen identification number from the national identification number service.
