Microservices Using Spring Boot and Spring Cloud Microservices is the hot buzzword in software development and many organizations prefer building their enterprise applications using microservices architecture. In the Java community, Spring Boot is the most widely used framework for building both monoliths and microservices. I am planning to write a series of articles covering how to build microservices using Spring Boot and Spring Cloud . In this article, we are going to learn about the following: Monoliths What are microservices? Advantages of microservices Challenges with microservices Why Spring Boot and Spring Cloud are a good choice for microservices Introducing the application Traditionally, we are building large enterprise applications in a modularized fashion (?!) but finally deploy them together as a single deployment unit (EAR or WAR). These are called monolithic applications. There are some issues with the monolithic architecture, s...
Docker Tutorial with Hello World Example Docker is a developer tool to package applications along with their runtime environment, so anybody can deploy and run them in any other machine without facing runtime environment conflicts. It is very similar to virtual machine concept ( virtualization ), where you can get a VM image and run it on any supporting hardware. All internal programs in VM will function as they were packaged originally. Difference between a VM and a docker image is that docker image does not package whole virtual operating system. It uses the OS resources just like other process in developer’s machine, only application and it’s runtime specific dependencies are packaged ( Containerization ). Docker allows users to publish docker images and consume those published by others in repositories like Docker Hub . In this tutorial, learn to install Docker container in windows , to create docker image and to deploy Docker i...
