You can use CloudWatch Container Insights to collect, aggregate, and summarize metrics and logs from your containerized applications and microservices. Container Insights is available for Amazon Elastic Container Service, Amazon Elastic Kubernetes Service, and Kubernetes platforms on Amazon EC2. The metrics include utilization for resources such as CPU, memory, disk, and network. Container Insights also provides diagnostic information, such as container restart failures, to help you isolate issues and resolve them quickly.
how Capacity Providers can help us in managing autoscaling for EC2 backed tasks, as well as ways to implement cost savings when running Fargate tasks. We will implement two capacity provider strategies in our cluster:
For a Fargate backed ECS service, we will implement a strategy to deploy that service as a mix between Fargate and Fargate Spot.
For an EC2 backed ECS service, we will implement Cluster Auto Scaling by increasing the task count of a service beyond the capacity available. This will require the backend EC2 infrastucture to scale to meet the demand, which the ECS cluster autoscaler will handle.
Blue/Green deployment is a technique for releasing an application by shifting the traffic between two identical environments running different versions of the same application. Blue/Green deployment is recommended for critical workloads since it mitigates the risks associated with deploying software, such as downtime and rollback capability.
Traditionally, with in-place upgrades, it was difficult to validate your new application version in a production deployment while also continuing to run your old version of the application. After you deploy the green environment, you have the opportunity to validate it. If you discover the green environment is not operating as expected, there is no impact on the blue environment. You can route traffic back to it, minimizing impaired operation or downtime, and limiting the blast radius of impact.
we will deploy a stateful workload on ECS Fargate with storage persisting on EFS. There are many reasons for wanting to deploy a stateful workload on containers, with some examples being:
Content Management Systems like Wordpress, or Drupal. Sharing static content for web servers Jenkins Master Nodes Machine learning Relational Databases for dev/test environments
