Docker - Coggle Diagram

- - - - Features:
        
        Launch Docker containers on AWS
        
        Do not provision EC2 instances
        
        Serverless function of ECS
        
        AWS runs containers for me based on CPU/ RAM I need
      - Fargate launch type for ECS: (image)
        
        ENI to access ECS task
        
        To bind private IP to task
    - - EC2 Instance Profile:
        
        Used by ECS Agent
        
        Makes API calls to ECS service
        
        Send container logs to CloudWatch Logs
        
        Pull Docker image from ECR
        
        Reference sensitive data in Secrets Manager or SSM Parameter Store
      - ECS Task Profile:
        
        Allow each task to have a specific role
        
        Use different roles for the different ECS Services you run
        
        Task Role is defined in the task definition
    - - Service CPU Usage example: (image)
        
        2 levels of scaling
        
        Scaling at service level (use CloudWatch Metric - ECS Service CPU Usage and CloudWatch Alarm)
        
        EC2 instances scaling (use ECS Capacity Providers)
        
        Not using Fargate
      - SQS Queue example: (image)
        
        2 levels of scaling
        
        Scaling at service level (use CloudWatch Metric - Queue Length and CloudWatch Alarm)
        
        EC2 instances scaling (use ECS Capacity Providers)
      - ECS leverages the Application Auto Scaling service to increase or decrease the desired count of tasks in ECS service automatically
