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
