This pattern creates an ECS Fargate application that consumes an Amazon SQS queue and it scales on the basis of queue size
This sample project demonstrates how target tracking scaling policy works with an ECS Fargate application
We have a python application under consumer/app.py that consumes messages from an SQS queue. The application is containerised and the image is pushed to an ECR registry.
On the basis of a target value of the SQS metric - ApproximateNumberOfMessagesVisible, the count of tasks of the cluster will increase.
Again, when the actual value drops below the target value, the count of tasks comes down to the initial value.
