Core Concepts to Master
Microservices Architecture
A microservices architecture is a software development technique that structures an application as a collection of small, independent services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. This approach allows for greater flexibility, scalability, and maintainability, as well as improved fault tolerance and resilience.
Spring Boot
Spring Boot is a popular Java-based framework for building web applications and microservices, providing a lightweight and flexible way to develop, test, and deploy applications. With Spring Boot, developers can quickly create web applications, RESTful APIs, and microservices, leveraging a wide range of features, including auto-configuration, embedded servers, and production-ready features.
Exception Handling
Exception handling is a critical aspect of software development, enabling developers to manage and handle errors, exceptions, and other unexpected events in a robust and reliable manner. In Java, exception handling is achieved through the use of try-catch blocks, which allow developers to catch and handle exceptions, providing a clear and concise way to manage error handling and debugging.
