Core Concepts to Master
Java 8 Features
Java 8 introduced several new features, including lambda expressions, method references, functional interfaces, and the Stream API, which have revolutionized the way we write Java code.
Spring Boot Architecture
Spring Boot provides a simplified way of building production-grade Spring-based applications, with a focus on convention over configuration and auto-configuration.
RESTful API Design
RESTful APIs are designed to be stateless, cacheable, and scalable, with a focus on resource-based URLs, HTTP methods, and status codes.
Microservices Architecture
Microservices architecture involves breaking down a monolithic application into smaller, independent services that communicate with each other using APIs.
Containerization with Docker
Docker provides a lightweight way of packaging and deploying applications, with a focus on isolation, portability, and scalability.
Cloud Platforms (AWS, Azure, GCP)
Cloud platforms provide a scalable, on-demand infrastructure for deploying and managing applications, with a focus on scalability, reliability, and security.
Kubernetes Concepts
Kubernetes provides a container orchestration system for automating the deployment, scaling, and management of containerized applications.
