Open Telekom Cloud for Business Customers

Elastic Cloud Server (ECS)

With the help of virtual machines (VM) from the cloud, you can book server capacities quickly and flexibly via the Internet. We have combined our broad portfolio of VM variants – so-called flavors – for you in our Elastic Cloud Server portfolio. You determine specifications such as the desired operating system or service duration. Since hardware components such as RAM and CPUs are emulated virtually, you can combine them freely according to your wishes. The result are flavors that are perfectly tailored to your needs. The Open Telekom Cloud uses KVM as a hypervisor to provide virtual machines in a total of nine performance classes via the ECS offering. These cover all possible use cases, such as graphics calculations, virtual workplace systems and Big Data functions.

High Quality

  • Reliability: Our Service Level Agreements (SLAs) guarantee 99.95% availability of the ECS service. The ability to run VMs in multiple spatially separated Availability Zones (AZs) makes it easy to minimize outages.
  • Efficient networks: Our ECS offer relies on the quality-of-service principle: by allocating resources dynamically and prioritized, it optimizes communication in the network, provides reliable performance and uses bandwidth efficiently.
  • Security: In the event of a failure of the physical server on which the virtual ECS instance is located, the system automatically restores the affected workload.

We use OpenStack as our software basis. This open-source solution is further developed by a dedicated community that subjects the code to a rigorous public review before each release to rule out errors and security gaps.

Flexible Billing

ECS includes three pricing models: Elastic (hourly billing), Reserved (discounted monthly pricing for continuous use), and Reserved Upfront (increased discounts through prepayment). The license costs for the operating system are already included.

Bring your own license (BYOL) allows you to use your existing operating system license. This means you do not have to apply for a new one. With the BYOL license type, you can thus significantly reduce your costs when booking the ECS.
