Image Management Service (IMS)

Manage operating systems with ease

Without an operating system, it would be impossible to use virtual hardware resources like the Elastic Cloud Server. Therefore, clouds provide collections of operating system images, also referred to as image management systems. The images contained therein are optimized for use in cloud environments. When rolling out virtual machines, an operating system is automatically installed. For installing the operating system, the flavors must have a minimum amount of block storage (elastic volume storage), i.e. a system disk.  The size of this virtual disk depends on the operating system used. Images of up to 128 GB can be uploaded. The RAW and ZVHD2 formats are exceptions to this, with a maximum upload size of 1 TB.

Image Management Service in the Open Telekom Cloud

Alongside the public images provided for use in the Open Telekom Cloud, users can also install their own operating system or application images. In this case, the user assumes responsibility that the operating system or application is used in conformity with its license and for its technical functionality. The Open Telekom Cloud offers a bring-your-own-license model for this purpose. Private images can be added to public images in order to enable users to deploy them again at any time. These images remain private and cannot be deployed by other users, provided that the owner does not share them. After sharing, images can be used jointly within an organization. The Open Telekom Cloud is compatible with the image formats QCOW2, VMDK, RAW, VHD, ZVHD2 and VHDX. A list of available public images is available in the Image Factory, which serves to prepare images for use with the Open Telekom Cloud. The license costs of the operating system images are included in the costs for the respective virtual servers.
