AWS ECS Fargate memory limit plays an important role in ensuring the task does not terminate. Read on to find out more. 

At Bobcares, we offer solutions for every query, big and small, as a part of our AWS Support Services.

Let’s look at how our AWS Support Team helped our customers learn more about the AWS ECS Fargate memory limit.

About AWS ECS Fargate memory limit

AWS ECS Fargate is responsible for letting users build as well as deploy containerized applications without managing the infrastructure. Cluster management tasks are considerably challenging and tend to add a lot of additional trouble for developers who are keen on deploying appreciation as fast as possible.

In other words, AWS ECS Fargate simplifies deploying and running containerized applications. We can run an application on Fargate with these steps:

• • To begin with, we have to package our application in containers.
  • Then, specify memory and CPU requirements.
  • Next, define IAM or networking policies as required.

According to AWS documentation, we require CPU and Memory properties in the AWS::ECS::TaskDefinition for AWS ECS Fargate. However, not in the ContainerDefinition within the resource if Fargate is used.

According to our Support Team, if a container does not have specific limits in TaskDefintion, the container uses all available resources for the task. In fact, this is required for an AWS ECS Fargate task.

In other words, we do not have to define them in case there is only a single container in TaskDefinition.

However, if a task has more than one container, AWS ECS Fargate distributes the resources evenly among all the containers.

In fact, when we register a task definition, we can state the total memory and CPU for the task. However, this is different from the memory and CPU values at the container definition level.

For instance, if the task requires 1vCPU and 2GB of memory and we set the task memory at 2GB, the task terminates if it exceeds this limit.
