====== NHR Container Workshop ======
**December 13th 2021, 13:00 - 17:15** 

The installation and configuration of applications in HPC is highly dependent on the actual software and hardware environment that users find on the HPC systems of the data centers (OS distribution, libraries, modules, network, architectures). It usually complicates the version provisioning of the software as well as migration between data centers. Both are usually associated with a certain support effort. When moving to cloud resources (for example, to offer applications as on-demand services) or to user’s hardware (for small tests and development) the software environment must be reproduced manually. NHR Project "Container and Container Management" aims to mitigate these issues and offer a solution for users by means of Container technologies.

In this workshop we will present a couple of solutions that are already in place by data centers, share experience and discuss future improvements of containers in HPC.
