Since version 3 of calServer, we have relied entirely on Docker integrated services. With the help of this container technology, complex applications can be packed into compact, immediately executable applications. Docker now even works on any modern Windows PC. However, the system shows its great strength on an internal/external cloud server. Non-stop updates, load control, web, database and file services with one click ... all possibilities that were hardly conceivable in laboratory applications just a short time ago.
