OPNFV Doctor is building a framework to have infrastructure maintenance and upgrade done in interaction with the application running on top of it. By having this, the application is able to keep zero downtime with its service during the operations as well as to be able to utilize new capabilities of the upgraded underlying compute nodes. Not only the application benefits from this, but also the infrastructure admin, as he can even request to down scale the application. That is, for rolling upgrades in networking systems where there may not be sufficient resources to perform rolling upgrade, e.g. due to strict Return on Investment (ROI) policy for the special Telco hardware used. Using the proposed framework, you can first down scale the application to free capacity on your hardware for then triggering the rolling upgrade. Presentation shows how this and much more will be accomplished.
Presentation is targeted for VNF and Telco infrastructure providers as well as operators. Also developers interested in having the open source way of implementing Telco infrastructure maintenance and upgrade with VNF interaction.
