What is AWS Fargate?

Last updated on 


AWS Fargate is a serverless compute engine for containers that enables you to run containers without having to manage the underlying infrastructure. It is part of the Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS) offerings, allowing you to deploy and manage containers in a more simplified and abstracted manner.

Here's a technical breakdown of AWS Fargate:

  1. Container Orchestration:
    • AWS Fargate works with container orchestration services like ECS and EKS. These services help manage the deployment, scaling, and orchestration of containerized applications.
  2. Serverless Computing:
    • Fargate is considered "serverless" because it abstracts away the infrastructure management tasks from the user. You don't need to provision or manage the underlying EC2 instances; AWS takes care of it.
  3. Isolation and Security:
    • Fargate ensures strong isolation between tasks by running each task in its own kernel runtime environment. This provides security and ensures that one task cannot interfere with another.
  4. Resource Management:
    • Fargate allows you to specify the amount of CPU and memory resources your containerized applications need. You only pay for the vCPU and memory you use, which makes it cost-effective.
  5. Task Definition:
    • You define your containerized applications and their configurations using a task definition. This includes details like container images, CPU and memory requirements, networking settings, and other parameters.
  6. Networking:
    • Fargate integrates with Amazon VPC (Virtual Private Cloud) to provide network isolation for your containers. You can configure networking aspects such as subnets, security groups, and IP addresses.
  7. Load Balancing:
    • Fargate seamlessly integrates with Elastic Load Balancing (ELB), allowing you to distribute incoming traffic across multiple containers for high availability and fault tolerance.
  8. Auto Scaling:
    • Fargate supports auto scaling, enabling your containerized applications to automatically scale in or out based on defined policies and criteria.
  9. Logging and Monitoring:
    • You can use AWS CloudWatch for logging and monitoring your Fargate tasks. This includes monitoring container metrics, setting up alarms, and collecting logs.
  10. Integration with Other AWS Services:
    • Fargate integrates with various AWS services like IAM (Identity and Access Management), CloudFormation, CloudWatch, and more, allowing you to build comprehensive and scalable solutions.
