Dedicated Host (DeH)

A dedicated hardware pool for virtual machines

In contrast to Elastic Cloud Servers (ECS), which are made available from a pool that is accessible to all cloud users, dedicated hosts are provided individually for each customer. This customized hardware offers an increased level of security and performance while avoiding the “noisy neighbor” effect (negative influences on the performance of the allocated resources caused by other users). In contrast to Bare Metal Servers, the hardware resources for dedicated hosts are virtualized. In addition, dedicated hosts enable users to design their own virtual machines in various sizes.

Dedicated hosts in the Open Telekom Cloud

The “Apply for DeH” function removes a physical host from the resource pool and assigns it to a user. It is then exclusively available for this user. Virtual machines can be provided on this dedicated host – the only limit being the size of the host. The storage and network resources are also provided in a shared model for the dedicated host. As is the case with the ECS, users should consider their specific use cases when choosing a dedicated host.

The Open Telekom Cloud offers four dedicated hosts for general use cases as well as one host each for RAM-intensive, disk-intensive and high-performance scenarios. Xen and KVM are currently used as hypervisors. A dedicated host is billed in the same manner as an Elastic Cloud Server (ECS). The prices for the operating system licenses for the instances running on the dedicated host are also charged.
