How AWS ECS and Fargate works
Amazon ECS (Elastic Container Service) and AWS Fargate work together to provide a platform for running and managing containerized applications on AWS. Here’s how they work:
Amazon ECS
- Amazon ECS is a fully managed container orchestration service. It allows you to run and manage Docker containers at scale.
- You define your application as a collection of tasks, each task consisting of one or more Docker containers.
- ECS manages the placement of these tasks onto a cluster of EC2 instances that you manage.
- You specify the compute resources (CPU, memory) required for each task, and ECS ensures that the tasks are distributed across the cluster efficiently.
AWS Fargate
- AWS Fargate is a serverless compute engine for containers that works with ECS. It allows you to run containers without managing the underlying infrastructure.
- With Fargate, you define your tasks in the same way as with ECS, but you don’t need to provision or manage any EC2 instances.
- Instead, Fargate automatically provisions and scales the infrastructure needed to run your containers based on the CPU and memory requirements you specify.
- You only pay for the resources (CPU and memory) consumed by your containers, with billing based on per-second granularity.
How They Work Together
- You can choose to use either ECS with EC2 instances or ECS with Fargate, depending on your specific requirements and preferences.
- ECS provides flexibility and granular control over your container environment, making it suitable for organizations with specific infrastructure needs or existing investments in EC2.
- Fargate, on the other hand, offers a more simplified and serverless approach, where you can focus solely on your application without worrying about infrastructure management.
- Both ECS and Fargate integrate seamlessly with other AWS services, such as Elastic Load Balancing (ELB), Amazon CloudWatch for monitoring, and AWS Identity and Access Management (IAM) for security, providing a comprehensive platform for running and managing containerized applications on AWS.
Difference Between AWS (Amazon Web Services) ECS And AWS Fargate
While both AWS ECS and Fargate play in the container orchestration field, their approaches diverge like two paths on a mountain trail. ECS empowers you with direct control over the underlying infrastructure, like an experienced builder crafting a custom container home. You choose and manage the bricks and mortar (EC2 instances) for a personalized container environment. On the other hand, Fargate takes the “ready-to-move-in” route, handling the infrastructure behind the scenes like a well-equipped concierge. You simply focus on your containers, leaving the server management to Fargate. The choice comes down to whether you seek control of a hands-on builder or the ease of a pre-built haven for your containerized applications.
