What is the best alternative to cronjobs, guaranteeing high availability and jobs not being duplicated?

do you want platform based or language based? I mean if you want any language specific then I have couple of suggestions

@arpit1997 thanks for your feedback! My goal is to trigger a PHP script that is being run inside a Docker image on an Amazon ECS-Optimized AMI.

What kind of suggestions do you have?

Rundeck

@Pavr have you ever used it? Why should I go with it instead of any other alternatives?

@AlexDeLarge what would be the point of asking advice and then not listening to the people giving advice?

@py2js and @Pavr were you been able to check my answers meanwhile?

@AlexDeLarge thanks! Wow, I wasn't aware that Elixir was able to do that.

I am not really sure if I am going to Elixir on this one because this is meant to be used in my company and I'm more driven in implementing a tool than a full stack on the project. :) I will take it, however, to add to my learning stack!
