Dedicated Host (DeH)

With Dedicated Host (DeH), the Open Telekom Cloud offers physical servers for you to run your own virtual machines even more easily on a host-level isolated environment. The physical machines can be allocated flexibly and easily via the console in order to start directly with the provisioning of their own workloads. 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.

Reasons for DeH in the Open Telekom Cloud

Compliance

The allocated resources run in a GDPR-compliant environment and fulfil all European requirements to run secure workloads with the scalable options of a cloud. Non-European authorities have no access.

Performance

The customer has full control which applications will affect the allocated hardware and how many resources they would like to block. This customized hardware offers an increased level of security and performance, while avoiding the “noisy neighbor” effect (negative influences on allocated resource performance caused by other users).

Flexibility

Run only the VMs and applications that you want. There are multiple DeH types for every business requirement, e.g., memory or compute accelerated workloads. The hardware can be used in just few clicks and is charged on demand.

Security

DeH provides another layer of security at the physical level. In the event of a failure of the physical server on which the virtual ECS instance resides, the affected workload will be restored on another available dedicated host.

Transparency

The isolation of computing resources allow an overview and full control of which workloads are running on the machine. Compared to common ECSs, unused resources, such as vCPU or memory of a host, are visible.

Simplicity

In contrast to Bare Metal Servers (BMS), the hardware resources for dedicated hosts are virtualized. DeH allows users to design their own virtual machines in different sizes. Via the visual console or the API, DeH and ECS VMs can be easily managed via Terraform, for example.

BYOL

The Dedicated Host Service can help to reuse existing licences for RHEL, SUSE (SLES), Microsoft Windows Server, Microsoft SQL Server, Microsoft Office etc. This means you do not have to apply for a new one. With the BYOL license type, you can thus significantly reduce your costs.

Flexible billing

DeH 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.

Cloud service integration

DeH is easily integratable with other services to provide computing, storage, and network resources. Linked services include ECS, VPC, IMS, EVS, CSBS, CES, KMS and many more services to meet business needs in a cloud.

DeH Type Overview

General Purpose

This DeH type provides a balanced level of compute, storage, and network capacity, and the ability to quickly add additional resources during peak loads. There are two types of dedicated hosts for general purposes. The standard s2 and the s2- medium, which has a smaller capacity to keep costs down.

Scenarios:

  • Applications
    The supported general purpose ECS s2 are suitable for applications that have no special requirements in terms of CPU performance, memory space, hard disk capacity or bandwidth, but demand high standards of security and reliability. They require low initial investment and maintenance costs.
  • Application scenarios
    Application scenarios include corporate websites, office environments, corporate R&D and testing activities, web servers, and small databases.

Dedicated General Purpose

This DeH type uses scalable processors with high-speed intelligent network adapters. It is optimized for powerful and stable computing performance and network bandwidths with a high PPS (packets per second) count.

Scenarios:

  • C3 ECSs
    Small and medium-sized databases, cache servers and search clusters with high stability requirements, also enterprise applications of different types and sizes.
  • C4 ECSs
    Websites and web applications, general databases and cache servers, and medium and large enterprise applications with stringent compute and network performance requirements.

Memory-Optimized

Memory-optimized DeH use processors optimized for high and stable computing performance. They offer a 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:

  • High-performance relational databases (e.g. MySQL) and NoSQL databases (e.g. MongoDB or Cassandra)
  • Distributed web-based caches used to improve the performance of dynamic websites with database connections (e.g., Memcached or Redis)
  • Applications for processing big unstructured data in real time (e.g., financial services or Hadoop/Spark clusters)
  • High-performance computing (HPC) and electronic design automation (EDA)
