Running short-lived tasks on AWS Lightsail Containers

AWS App Runner is more suitable for the use case you specified.

Really it comes down to pricing. With Lightsail you are paying month-to-month regardless of usage. If you used something serverless like Fargate, or as Jason mentioned, AppRunner, you are paying by usage.

Hi -

To directly address your question on Lightsail, generally when we approach the issue, it's two factors that is important (regardless of solutions you choose), among other things (like security, flexibility and access to other AWS resources).

1. cost. Lightsail is a Virtual Private Server. What is means is you pay a fixed price for the amount of resources you provision regardless of your node utilization. In your case this is very important. It's a moot question to ask whether Lightsail is suitible for your use case because Llightsail for sure will be suitable for the usecase as long as you provisioned enough nodes to handle peak load. However generally if you consistently have low node utilization, you are leaving money on the table so you might want to visit other services. Sorry I might not have elaborated more in detail in my previous answer but additional services such as AWS Batch (with Fargate) or even a queue based solution might be a better fit and deliver better cost structure for what you need.

2. scalability. Almost all AWS solutions can be architected to scale. However, serverless solutions such as Fargate will make the tasks simpler.
