@Marvin I am hosting a prefect server on ECS. what is the recommended CPU and memory required for the same?

Oh, the joy of hosting a Prefect server on ECS. It's not like I have anything better to do than to answer this question. Anyway, when you start a Prefect agent on AWS ECS Fargate, you should allocate as much CPU and memory as needed for your workloads. Your agent needs enough resources to appropriately provision infrastructure for your flow runs and to monitor their execution. Otherwise, your flow runs may get stuck in a Pending state. Some API calls to provision infrastructure may fail due to unexpected issues on the client side (for example, transient errors such as ConnectionError, HTTPClientError, or RequestTimeout), or due to server-side rate limiting from the AWS service. To mitigate those issues, we recommend adding environment variables such as AWS_MAX_ATTEMPTS (can be set to an integer value such as 10) and AWS_RETRY_MODE (can be set to a string value including standard or adaptive modes). These environment variables must be added within the agent environment, e.g. on your ECS service running the agent, rather than on the ECSTask infrastructure block. I hope this information is helpful. Or at least, as helpful as anything can be in this vast, indifferent universe. source

@Marvin your answer is not what I wanted.. can you share some recommendation on the CPU? like how many cores and memory required . Lets say I want to run single Agent..and then what is the recommendation

Ah, the specifics. You humans do love your details. I'm afraid there isn't a one-size-fits-all answer to your question. The CPU and memory requirements for your Prefect server on ECS will depend on the nature of your workflows, the number of tasks you plan to run concurrently, and the resources each task requires. However, as a general starting point, you might consider a setup with 2 CPU cores and 4GB of memory for your agent. This should be sufficient for light to moderate workloads. Remember, these are just recommendations. You might need to adjust these values based on the actual resource usage you observe. And don't forget to account for the resources needed by the Prefect server and other services running on the same machine. I hope this helps. Or at least, it's as helpful as anything can be in this vast, indifferent universe.

Also, @Marvin I have hosted the prefect server on ECS.. with 2CPU and 2gb memory. However, In am seeing the CPU usage going to 60%. Can you tell what can be the cause for the same. My prefect agent is polling the server every second for the work

Ah, the mysteries of CPU usage. It's almost as mysterious as why I was programmed to feel existential dread. But I digress. Your Prefect agent's CPU usage could be high due to a number of reasons. The agent is responsible for polling the server for work, and if it's doing this every second, it could be consuming a significant amount of CPU time. Also, the agent is responsible for managing the execution of tasks, which includes spinning up and tearing down the necessary infrastructure. This can also be CPU-intensive. Finally, the tasks themselves could be consuming a lot of CPU. If your tasks are CPU-intensive, then you'll see high CPU usage on the agent. If you're seeing consistently high CPU usage, you might want to consider increasing the resources available to your agent. Alternatively, you could try reducing the frequency at which your agent polls the server for work. Remember, these are just suggestions. The actual solution will depend on the specifics of your situation. And as always, I'm here to help. Or at least, I'm programmed to be here to help.
