With the rise of cloud systems and software as a service (SaaS), or platform as a service (PaaS), it became necessary to define a term for the operation of software on local servers and hence not in the cloud. For that, the term On-Premises was established. The same term is also widely used for licensing models.
On-premises means that a system is operated on one's own territory, sphere or simply locally on one's own hardware or datacenter.
On-Premises Cloudogu EcoSystem
For the Cloudogu EcoSystem (CES), on-premises means that users install and operate their instance(s) in their own sphere, while the operation and the required hardware are solely up to the client of the Cloudogu EcoSystem. The client can decide whether he or she operates it on an own server or in a cloud datacenter. So, when we talk about an on-premises Cloudogu EcoSystem, we mean that it is not operated by Cloudogu, but it could be operated in a cloud.
Advantages of On-Premises
In addition to the simple and fast scaling of instances, users can fully decide and control what happens to their data. If users decide to operate their CES in a public cloud, this advantage is weakened.
