A team of developers has an application that currently runs off Docker. You recently read about serverless technologies, which aim to remove infrastructure management burden. When you bring this up with your team, they retort that the application "just can't do serverless." The team states that they don't want to have to rewrite the application and don't think that their long$-$running tasks are suitable for serverless.

Which service provides the least infrastructure management burden on the developers but still meets the team's requirements?
