5. Gap analysis in upstream projects¶

This section provides a list of gaps in upstream projects for realizing resource reservation and management. The gap analysis work focuses on the current OpenStack Blazar project [BLAZAR] in this first release.

5.1. OpenStack¶

5.1.1. Resource reservation for future use¶

Category: Blazar
Type: ‘missing’ (lack of functionality)
Description:
- To-be: To reserve a whole set of compute/storage/network resources in the future
- As-is: Blazar currently can do only compute resource reservation by using “Shelved VM”
Related blueprints:
- https://blueprints.launchpad.net/blazar/+spec/basic-volume-plugin
- https://blueprints.launchpad.net/blazar/+spec/basic-network-plugin
- It was planned in Blazar to implement volume and network/fixed ip reservations

5.1.2. Resource reservation update¶

Category: Blazar
Type: ‘missing’ (lack of functionality)
Description:
- To-be: Have the possibility of adding/removing resources to an existing reservation, e..g in case of NFVI failure
- As-is: Currently in Blazar, a reservation can only be modified in terms of start/end time
Related blueprints: N/A

5.1.3. Give me an offer¶

Category: Blazar
Type: ‘missing’ (lack of functionality)
Description:
- To-be: To have the possibility of giving a quotation to a requesting user and an expiration time. Reserved resources shall be released if they are not claimed before this expiration time.
- As-is: Blazar can already send notification e.g. to inform a given user that a reservation is about to expire
Related blueprints: N/A

5.1.4. StormStack StormForge¶

5.1.4.1. Stormify¶

Stormify enables rapid web applications construction
Based on Ember.js style Data stores
Developed on Node.js using coffeescript/javascript
Auto RESTful API generation based on Data Models
Development starts with defining Data Models
Code hosted at github : http://github.com/stormstack/stormify

5.1.4.2. StormForge¶

Data Model driven management of Resource Providers
Based on Stormify Framework and implemented as per the OPNFV Promise requirements
Data Models are auto generated and RESTful API code from YANG schema
Currently planned key services include Resource Capacity Management Service and Resource Reservation Service
List of YANG schemas for Promise project is attached in the Appendix
Code hosted at github: http://github.com/stormstack/stormforge

5.1.4.3. Resource Discovery¶

Category: StormForge
Type: ‘planning’ (lack of functionality)
Description
- To-be: To be able to discover resources in real time from OpenStack components. Planning to add OpenStack Project to interface with Promise for real time updates on capacity or any failures
- As-is: Currently, resource capacity is learnt using NB APIs related to quota
Related Blueprints: N/A
