Which Cloud PaaS can be used for multiple projects with small cron tasks?

Question

Amazon Web Services

There are many small projects hosted in git repositories.
It is necessary to run a certain command inside the project every n-hours/minutes/seconds. No permanent workers, just cron jobs. Due to the large number of projects, it is impossible to independently upload each one to the server, so working with CI (Gitlab CI, in this case) is also important.
For the convenience of work (a non-developer poked a button - the project turned off, poked it again - it turned on, while not affecting other projects), I study a variety of cloud solutions. Read about Heroku Scheduler, how are they with the cost?
What other options are there?

Answer 1

Probably the question is no longer relevant, but if the tasks themselves are completed quickly enough, then I would highly recommend AWS Lambda. Now they have added crons there + the ability to pass through environment variables. You will have to tinker with CI a little, but in the end, under certain conditions, you can get a free solution.
And so, there are really no skedulers for jobs. I ended up writing my little one, a lot of people do that too, because solutions like Mesosphere or others are quite heavy and difficult to set up and maintain.
