Job Description


### Java
Java is a highlevel classbased objectoriented programming language that is designed to have as few implementation dependencies as possible. It is a generalpurpose programming language intended to let application developers write once run anywhere (WORA) meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

### J2EE (Java 2 Platform Enterprise Edition)
J2EE now known as Jakarta EE (after being transferred to the Eclipse Foundation) is a set of specifications extending Java SE (Standard Edition) with specifications for enterprise features such as distributed computing and web services. J2EE provides an API and runtime environment for developing and running largescale multitiered scalable reliable and secure network applications. Some key components include:

**Servlets:** Java classes that run on a server and handle requests and responses.
**JSP (JavaServer Pages):** A technology that helps in creating dynamically generated web pages based on HTML XML or other document types.
**EJB (Enterprise JavaBeans):** Serverside components that encapsulate the business logic of an application.
**JPA (Java Persistence API):** A specification for accessing persisting and managing data between Java objects and relational databases.

### Microservices
Microservices is an architectural style that structures an application as a collection of loosely coupled services. In a microservices architecture services are finegrained and the protocols are lightweight. The key benefits of microservices are:

**Scalability:** Each service can be scaled independently.
**Flexibility in Technology:** Different services can be developed using different programming languages and technologies.
**Resilience:** Failure of one service does not affect the others.
**Ease of Deployment:** Services can be deployed independently.

### Java/J2EE in Microservices
Java and J2EE technologies can be effectively used to develop microservices. Several frameworks and tools are available in the Java ecosystem to support microservices development including:

**Spring Boot:** A rapid application development framework that simplifies the creation of standalone productiongrade Springbased applications. It is often used for building microservices.
**Spring Cloud:** Provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management service discovery circuit breakers routing).
**Dropwizard:** An opensource Java framework for developing RESTful web services.
**MicroProfile:** An initiative to optimize Enterprise Java for a microservices architecture by providing a baseline platform definition that includes core J2EE technologies along with specific microservices capabilities.

### How They Interrelate
**Development:** Java is the programming language J2EE provides the enterpriselevel features and microservices is the architecture style. Together they allow developers to build robust scalable and maintainable applications.
**Frameworks:** Frameworks like Spring Boot and Spring Cloud streamline the development of microservices in Java leveraging the extensive features offered by J2EE.
**Deployment:** Microservices can be deployed independently often in containers (e.g. Docker) and managed using orchestration tools (e.g. Kubernetes).

### Example Workflow
1. **Define Business Requirements:** Identify the business functionalities that need to be implemented.
2. **Design Microservices:** Break down the application into smaller manageable microservices.
3. **Develop Services:** Use Java and J2EE technologies along with frameworks like Spring Boot to develop each microservice.
4. **Deploy Independently:** Deploy each microservice in a containerized environment.
5. **Manage and Monitor:** Use tools for service discovery configuration management and monitoring to manage the microservices architecture.

By combining Java J2EE and microservices organizations can build modern scalable and resilient applications that meet complex business requirements.
