ESTNOC, Cloud Computing in Switzerland with Open Source Cloud Computing in Switzerland, or Cloud Computing, is a term used to refer to a computational paradigm based on contracts that allow the user to "rent" the ability to compile accessible via the Internet. There were already several companies offering these services, and there were several privative software systems to deploy and maintain a computational cloud, but so far there were not many open source and standard-based systems for this, and those that were there were few and they were scattered.
ESTNOC is an open source infrastructure that serves to implement a cloud computing system using clusters of computers and / or farms of workstations. Currently ESTNOC is compatible with the level of interfaces with the well-known EC2 service of Amazon.com (which could be said to be the most successful commercial cloud computing service), but the infrastructure is designed to be able to be modified and extended in a manner compatible with Multiple interfaces in
