Prerequisites This article builds on the prior article about AWS Fargate. Add an Application Load Balancer For a long time, AWS has supported an HTTP(S) load balancing service in the form of an Elastic Load Balancer (now called a “Classic load balancer”). When paired with ECS, a classic load balancer...

Prerequisites This article builds on the prior article about AWS CodePipeline. Fargate History With an automated build process underway, it is now time to switch focus to the application’s runtime environments. We will be creating two environments: Development (aka. Dev) and Production (aka. Prod). Consider wether your project needs more...

Prerequisites This article builds on the prior article: CloudFormation. Continuous building via AWS CodePipeline Not only are we going to manage our application environments with Cloudformation but we are also going to manage our deployment pipeline in the same manner. CodePipeline (Not to be confused with CodeDeploy) is the Continuous...

Prerequisites This article builds on the prior article: Dockertize. Introduction In the articles leading up to this one, we’ve created a docker image of a minimal tested NodeJS microservice. Our next step is to deploy the docker image into a container running in the AWS cloud platform. AWS CloudFormation allows...
