Documentation Release Notes


Given the new Boron release of the DT Cloud Services cloud platform, this documentation was updated to incorporate the changes brought by the new release.

Boron is based on Openstack Stein and OVS SDN, with some changes in hardware components, services and features as listed below. The documentation has been updated to reflect both practical and technical implementation changes with links to the relevant sections. Many chapters have been extended with information on how to configure nodes for various applications and how to manage them. This is - in most cases - not dependent on the release of DT Cloud Services Cloud Services.

The table below points to a summary of the main changes in documentation.
