Enterprise Cloud
As part of the server and service consolidation, the ZIH has created the possibility to provide virtual servers. The ZIH thus offers its customers the opportunity to operate their own services within the ZIH infrastructure. The services are provided by virtual servers (virtual machines - VMs) that users can manage themselves.

Research Cloud
With the Research Cloud, the ZIH provides another service based on a TU-internal cloud solution for research and test purposes. The Self Service Portal allows users to create, operate and manage virtual machines within their personal resource quotas. This cloud solution is available to TU Dresden employees exclusively for internal TUD provisioning and testing. The virtual machines are provided in an internal network area with limited access to the Internet and without firewall protection.

Advantages of virtualization
- Better utilization of resources because many virtual machines (VM) can share an actual physical machine
- Better security, since one server (VM) can be set up per service
- Better load distribution by clustering
- Reduction of hardware, maintenance and operating costs
- Reduction of administrative expenses
The fail-safe operation of the physical servers is also protected by the use of structured network connections and NAS or SAN storage systems. The HA clusters consist of at least 3 powerful servers.
The following advantages are obtained for the user of a virtual machine (VM):
- Users do not have to worry about the hardware (procurement, installation, power supply, air-conditioning, maintenance)
- A backup of the complete VM for the purpose of disaster recovery is carried out by ZIH (possibly at intervals of several days). If a daily backup of important data in the VM is required, a separate file-based backup may have to be carried out independently - for large amounts of data, please coordinate with ZIH (Backup and Archive).
