Deploy Spring Boot and Docker Microservices to AWS using ECS and AWS Fargate

Image

Learn Amazon Web Services - AWS - deploying Spring Boot and Docker Microservices to AWS Fargate. Implement Service Discovery, Load Balancing, Auto Discovery, Centralized Configuration and Distributed Tracing in AWS.

Spring Boot is the No 1 Java Framework to develop REST API and Microservices. AWS (Amazon Web Services) is the No 1 Cloud Service Provider today.

How about learning AWS by deploying Spring Boot Docker Containers to Amazon Web Services using Elastic Container Service - ECS and AWS Fargate?

Course Overview

This course would be a perfect first step as an introduction to Amazon Web Services - AWS and the Cloud.

In this course, we deploy a variety of Java Spring Boot Microservices to Amazon Web Services using AWS Fargate and ECS - Elastic Container Service.

You will learn the basics of implementing Container Orchestration with ECS (Elastic Container Service) - Cluster, Task Definitions, Tasks, Containers and Services. You will learn about the two launch types of ECS - EC2 and AWS Fargate. In this course, we would focus extensively on AWS Fargate to simplify your Container Orchestration. You will learn to deploy multiple containers in the same ECS task.

You will learn to Build Container Images for your Java Spring Boot Microservice Projects.

You will implement the following features for your Microservices - Centralized Configuration Management with AWS Parameter Store - Distributed Tracing with AWS X Ray - Auto Scaling and Load Balancing with ECS, Elastic Load Balancers and Target Groups - Service Mesh using AWS App Mesh. You will learn the basics of AWS App Mesh - Mesh, Virtual Nodes and Virtual Services. You will learn to perform Canary Deployments using AWS AppMesh. - Service Discovery with Route 53 Hosted Zones and DNS. - Continuous Integration and Continuous Deployment with AWS Code Pipeline

You will learn to debug problems with deploying containers using Service events and AWS CloudWatch logs.

You will learn about automating deployments and creating a continuous delivery pipeline with AWS Code Pipeline. You will learn how to Auto Scale applications based on load as well as deploy multiple instances behind a load balancer using AWS ECS Fargate.

You will be using a number of AWS Services - ECS - Elastic Container Services, AWS Fargate, EC2 - Elastic Compute Cloud, S3, AWS CodePipeLine, AWS CodeBuild, IAM, CloudWatch, ELB, Target Groups, X Ray, AWS Parameter Store, AWS App Mesh and Route 53.

You will be using deploying a variety of projects to Amazon Web Services (AWS).
