Learning Outcome
4
Identify how these services work together
3
Understand the role of each service
2
Know what ECS, ECR, and Fargate are
1
Understand how Docker is used on AWS
Earlier, we learned
Containers can run applications easily
Now the next question is
How do we run and manage Docker containers on AWS...?
AWS provides managed container services for this
Docker is used to create and run containers
Let's Understanding
Think of running containers like running delivery trucks
AWS provides ready-made services for this work
You need a system
to run deliveries
You need a warehouse
to store goods
You don’t want
to manage every small detail
To store Docker images and run containers in the cloud,
ECS
Let’s understand each one clearly
Fargate
ECR
AWS provides three important services
What is Amazon ECR (Elastic Container Registry)?
Amazon ECR is a managed Docker image repository in AWS
Secure images using IAM
ECR is like Docker Hub, but inside AWS.
It is used to:
Store Docker images
Manage image versions
Why ECR is Needed
Controls who can push and pull images
ECR acts as the central storage for Docker images in AWS
Keeps Docker images secure
Works smoothly with other AWS services
What is Amazon ECS (Elastic Container Service)?
Amazon ECS is a container orchestration service
Handle scaling and availability
ECS decides how containers should run
It is used to:
Run Docker containers
Manage container lifecycle
Why ECS is Needed
Helps run containers reliably in production
ECS does not store images
Manages multiple containers easily
Reduces manual container management
it uses images from ECR to run containers
What is AWS Fargate?
AWS Fargate is a serverless compute engine for containers
Avoid EC2 instance management
With Fargate, you focus only on containers,
AWS manages the infrastructure.
It allows you to:
Run containers without managing servers
Why Fargate is Important
Pay only for used resources
Fargate works with ECS, not separately
No server provisioning
Automatic scaling
How ECS, ECR, and Fargate Work Together
Fargate runs containers without servers
Together, they form a complete Docker solution on AWS.
ECR stores Docker images
ECS manages and runs containers
