Public Services in OTC

The Open Telekom Cloud (OTC) offers a number of services to customer VMs that these can use without needing to have internet access.

While many of these are preconfigured in the public images from the OTC ImageFactory and thus will automatically be used, customers with private images will need to configure their images (and networks) to use these explicitly. Customers creating subnets via the API will also need to configure the name server (DNS) themselves.

Service Interruption on OTC

Executive Summary

The Open Telekom Cloud (OTC) will undergo major changes in December.

During this time, the Management/Control Plane (Web Interface and API) will be unavailable several times for a number of minutes. The User/Data Plane (Virtual Resources) will be unreachable for a few minutes as well. In addition, due to the nature of the changes, the Virtual Machines (ECS) will not be live-migrated during this round of updates; instead all VMs will be terminated and restarted a few minutes later (cold migration). The User Plane changes will be performed in AZ1 (eu-de-01) before changes are started in AZ2 (eu-de-02), so cloud native applications should not see a service disruption.
