clever cloud is a platform as a service from France. You hand over your code and the platform runs it, with runtimes for a broad set of languages including JavaScript, PHP, Java, Ruby and Python. The company also offers an object storage service called Cellar for files and static assets.
Running a PaaS from France makes clever cloud a European alternative to the American application platforms, with hosting and contract inside the EU. It suits development teams that want to deploy applications without maintaining servers of their own.
