This presentation outlines the benefits of implementing a Microservice over a monolithic architecture.

This is a deep journey into the realm of "microservice architecture", and in that I will try to cover each inch of it, but with a fixed tech stack of Java with Spring Cloud. Hence in the end, you will be get know each and every aspect of this distributed design, and will develop an understanding of each and every concern regarding distributed system construct.

Spring Boot is a framework for developing Java applications that reduces configuration and provides production-ready features. It allows developing Spring applications with minimal configuration by automatically configuring Spring and third-party libraries. Spring Boot provides starter dependencies to simplify build configuration and modules for autoconfiguration, CLI, monitoring, and more.

This document introduces ReactJS, a JavaScript library for building user interfaces. It discusses key React concepts like the virtual DOM, which is a JavaScript representation of real DOM elements that allows React to efficiently update the real DOM by comparing it to a new virtual DOM. It also covers one-way data binding in React, where data flows from parent to child components through props, while events flow in the opposite direction. Finally, it emphasizes that in React, everything is a component, and components manage their own state and receive immutable props from parent components.

Ben McCormick gave a presentation on how to save time by testing with Jest. He began with an introduction and explained that Jest is a JavaScript testing framework developed by Facebook that aims to solve common testing problems. He then demonstrated how Jest saves time through fast setup, writing tests quickly using familiar syntax and APIs, running tests in parallel and with a smart watch mode, and providing clear errors to fix tests fast. He concluded with a demo of Jest's features and took questions.

Spring Boot is a framework for creating stand-alone, production-grade Spring-based applications that can be started using java -jar without requiring any traditional application servers. It is designed to get developers up and running as quickly as possible with minimal configuration. Some key features of Spring Boot include automatic configuration, starter dependencies to simplify dependency management, embedded HTTP servers, security, metrics, health checks and externalized configuration. The document then provides examples of building a basic RESTful web service with Spring Boot using common HTTP methods like GET, POST, PUT, DELETE and handling requests and responses.

This document provides an overview of Apache Tomcat, a free and open-source web server and servlet container developed by the Apache Software Foundation (ASF) that implements the Java Servlet and JavaServer Pages (JSP) technologies. It discusses what Tomcat is, its role as a web application container, how to install and configure it, enable features like CGI and SSI, and addresses some common issues. The advantages of using Tomcat include that it is open source, lightweight, easily configured, stable, well documented, and free.

This session will explain 'Spring Security', a powerful and highly customizable authentication and access-control framework.
