@Marvin The ECS cluster for my Prefect worker is running into intermittent resource issues, sometimes because of multiple small runs and sometimes because more intensive runs have insufficient resources. What guidance is there for moving away from the t2.medium instance type initially recommended in the documentation?

When dealing with intermittent resource issues in your ECS cluster, it's important to optimize your instance type based on the workload requirements. Here's some guidance: 1. Instance Type and Capacity Providers: - The

t2.medium

instance type is a general-purpose instance, but it may not be suitable for workloads that require more CPU or memory. - Consider using ECS capacity providers to leverage a mix of instance types, including spot instances, or ASGs (Auto Scaling Groups) to handle variable workloads efficiently. - Refer to PR #5411 on PrefectHQ GitHub which enables the use of capacity providers in ECS Agent and ECSRun, supporting Fargate Spot and ASG's. 2. Adjusting Worker Types: - Review the ECS Worker Configuration and Setup Guide for detailed instructions on configuring a worker suitable for your needs. - Using EC2 for the ECS cluster can significantly reduce setup time compared to Fargate, which might be beneficial if setup times are contributing to resource constraints. 3. Scaling Your Cluster: - Make sure you have set up appropriate auto-scaling policies in your ECS cluster to add instances dynamically based on CPU and memory utilization. - VPC configuration is crucial when using EC2 to ensure efficient allocation of network resources.
