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.
Our service is operated in the EU under European management and is GDPR-compliant. Non-European authorities have no access.
Independent analysts confirm that the ECS of the Open Telekom Cloud provided the best price-performance ratio among comparable providers.
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.
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.
This ECS flavor provides a balanced level of compute, storage, and network capacity, and the ability to quickly add additional resources during peak loads.
Scenarios:
Flavor |
|
vCPU/Memory Ratio | 1:1 | 1:2 | 1:4 | 1:8 |
vCPUs | 1 - 32 |
Memory | 1 - 256GB |
Maximum Intranet Bandwidth | 8Gbit/s |
Hardware | Intel® Xeon® Skylake 6161 |
This flavor uses scalable processors with high-speed intelligent network adapters. It is optimized for powerful and stable computing performance and network bandwidth with high PPS (packets per second) count.
Scenarios:
Flavor | c3 | c4 |
vCPU/memory ratio | 1:2 | 1:4 |
vCPUs | 2 - 64 |
Memory | 4 - 256GB |
Maximum Intranet bandwidth | 40Gbit/s |
Hardware | Intel® Xeon® Skylake 6151 |
Memory-optimized ECS use processors optimized for high and stable computing performance. They offer a maximum memory size of 512 GB based on DDR4 for memory-intensive applications with high demands on network bandwidth and data throughput in Packets per Second (PPS).
Scenarios:
Flavor | m2 | m3 | m4 |
vCPU/memory ratio | 1:8 |
vCPUs | 2 - 64 |
Memory | 16 - 512GB |
Maximum Intranet Bandwidth | 40Gbit/s |
Hardware |

This flavor provides an even larger amount of memory than Memory-optimized ECS. It is used for applications that process large amounts of data and require low latency.
Scenarios:
Flavor | e3 |
vCPU/memory ratio | 1:12 | 1:14 |
vCPUs | 28 - 208 |
Memory | 348 - 2932GB |
Maximum Intranet bandwidth | 40Gbit/s |
Hardware | Intel® Xeon® Skylake 6151 |
This flavor is designed for applications that require sequential reading and writing to very large data sets in local disks (e.g., distributed Hadoop computing), as well as large-scale parallel data processing and log processing.
Scenarios:
Flavor | d2 |
vCPU/memory ratio | 1:8 | 1:9 |
vCPUs | 4 - 60 |
Memory | 32 - 540GB |
Maximum Intranet bandwidth | 17Gbit/s |
Hardware | Intel® Xeon® Gold 6151 |
Disk capacity | 1800GB |
ECS for high-performance computing offer many CPU cores, a large memory capacity and a high data throughput.
Scenarios:
Flavor | h|1 | h2 |
vCPU/memory ratio | 1:8 | 1:16 |
vCPUs | 16 - 32 |
Memory | 128 - 256GB |
Maximum intranet bandwidth | 13Gbit/s |
Maximum RDMA bandwidth | 100Gbit/s |
Hardware | Intel® Xeon® E5-2667 v4 |
The virtual machines of this flavor are equipped with graphics processors that are perfectly suited for floating point calculations. Therefore, they are especially useful for applications that require a very large number of simultaneous calculations.
Scenarios:
Flavor | p1 | p2 | p2v | g6 | pi2 |
GPUs | Nvidia P100, V100, T4 |
vCPU/memory ratio | 1:2 | 1:4 | 1:7 | 1:8 |
vCPUs | 8 - 80 |
Memory | 32 - 560GB |
Maximum intranet bandwidth | 30Gbit/s |
Hardware | Intel® Xeon® Cascade Lake 6266 |
