My load balancer is listening on ports 80 and 443 and redirecting all traffic on those ports to one target group where one to many Web Captioner application tasks are running. An application load balancer that redirects requests to healthy targets in a target group.The service uses this task definition to start one to many running instances, called tasks. A task definition that references a Docker image stored in your registry and defines CPU and memory requirements for that image.An Amazon Elastic Container Registry where Docker images will be stored.A service that belongs to the cluster that runs Fargate type tasks.The AWS stack includes the following resources that you will need to set up. It also abstracts away just enough of the work of server management so that I can spend more time on application development. I decided to use AWS ECS and Fargate for Web Captioner because of the redundancy and high availability it provides. Automatically scale the number of running instances up or down depending on CPU usage.Run constant health checks on instances, and if an instance fails, start a new one in its place.
Use a load balancer to distribute traffic among multiple instances.Configure multiple instances of your application to run concurrently for redundancy.
In conjunction with other AWS services, you can: Graphs are always cool.ĪWS Fargate and Elastic Container ServiceĪWS Fargate is a new technology in the Amazon Web Services Elastic Container Service that allows you to run a Dockerized application without having to provision virtual servers. With minimal effort, it’s also possible for me to create an additional stack (load balancer and all), and deploy to that.ĪWS also provides alerts if my application ever becomes unavailable (or the number of concurrent instances of my application falls below a threshold) and some cool graphs.
AWS FARGATE STARTUP TIME CODE
I can independently deploy different branches of code to each environment. With GitLab and AWS, I can make one-click deployments to my staging and production environments. This post explains how I deploy the Web Captioner application to a AWS Fargate task type using GitLab. Web Captioner now runs on AWS Elastic Container Service (ECS) and Fargate, services by Amazon that allow you to deploy a Dockerized application without having to configure servers.
