What is Fenix?

Optimized rolling infrastructure pluggable one-click maintenance, upgrade, scaling and life-cycle workflow with VNFM interaction guaranteeing zero impact on VNF service.

Infrastructure admin can call Fenix API to start a pluggable workflow session. This session will make needed maintenance, upgrade and scaling operations to infrastructure optionally in interaction with the application manager (VNFM) to guarantee zero downtime for its service. Interaction gives the ability for the application manager to know about new capabilities coming over maintenance to make his own upgrade. The application can have a time window to finish what he is doing, make own action to re-instantiate his instance or have Fenix to make the migration. Also, seamless application scaling or retirement will be possible.

As Fenix has above described project-specific messaging with information about instances affected towards application manager, it also has admin-level messaging. This messaging can tell what host is down for maintenance, so any infrastructure components can have this information. Special case for this messaging would also be telling about adding or removing a host.

The architecture is pluggable to manage different use cases, clouds and payloads. There is plugin for workflow used and for the pre-, host- and post-actions.

The latest addition is also the ETSI FEAT03 defined constraints for instances and instance groups that can be used to optimize any rolling workflow to be done in the shortest possible time window, while at the same time keeping zero impact on VNF service.

Development

Stein release notes

During Stein release, Fenix most important new features were the stories below:

  • 2004147 Ability to download plug-ins and SW changes
  • 2004146 Support for one-click upgrade
  • 2003846 Support for action plug-in
  • 2003830 Fenix workflow error handling and use of database

Train priorities

There was a session in Denver PTG to define the priorities.

As there were two non-Telco users wanting to start using Fenix, it was the most important thing driving the priorities:
https://etherpad.openstack.org/p/DEN2019-fenix-PTG

Also, there was a discussion about ETSI NFV harmonization:

Ussuri

Open Infrastructure Summit - Shanghai
PTG:https://etherpad.openstack.org/p/Shanghai2019-Fenix-PTG

The main priority:
Specification to start implementing ETSI FEAT03: NFVI software modification. https://fenix.readthedocs.io/en/latest/specifications/ussuri-etsi-feat03.html
