| Cells | Regions | Heat support multi-regions | Cascading | ||
|---|---|---|---|---|---|
| Pros. | A single Nova API endpoint for scaling out nova within a region | Discrete regions with separate API endpoints and no coordination between regions. | Heat as the multi-site orchestration engine for discrete regions | 1. Single OpenStack API ( Nova, Cinder, Neutron, Ceilometer, Glance, KeyStone ) for multi-site NFV cloud.2. OpenStack ( Nova, Cinder, Neutron, Ceilometer, Glance, KeyStone ) as the multi-site orchestration layer, discrete OpenStack instances consolidated.3. Global quota control by the cascading OpenStack.4.Image replication, 5.global resource view. | |
| Cons. | 1. Only Nova can scale out for multi-site.2. Using RPC message(including Nova Cinder Neutron) for cross-site communication, difficult for cross-site integration, upgrade, trouble shooting.3. Image service shared in multi-site, no solution for multi-site image management.4. No clear Ceilometer solution used in multi-site: Shared or multi-Ceilometer. | 1. Tenant’s resources are discrete and not connected by tenant’s isolated network.2. Networking across different site has to be set up manually.3. Lots of discrete service endpoints.4. No global quota control.5.discrete IP address space management | 1. Currently only VPN supported for project level cross-site networking automation 2.No solution for image management and distribution across multi-sites.3.Still Lots of discrete Nova /Cinder /Neutron /Ceilometer service endpoints.4.no good solution for global consistent resource view and quota control. 5.discrete IP address space management | 1. PoC just finished.2. Currently GRE tunneling/L2 provider network supported for project level cross-site networking automation. More cross-site networking mechanism need to be developed. | |
| Common Cons. | Only VPN supported for project level isolated cross-OpenStack networking, proper L2/L3 cross-OpenStack networking for VNFs should be identified and developed. | Only VPN supported for project level isolated cross-OpenStack networking, proper L2/L3 cross-OpenStack networking for VNFs should be identified and developed. | proper L2/L3 cross-OpenStack networking for VNFs should be identified and developed. | ||
| Shared services | Keystone, Nova-API, Cinder, Neutron, Glance, Ceilometer | Keystone | Heat,KeyStone | Nova, Cinder, Neutron, Ceilometer, Glance, KeyStone |
New identified upstream project that could address the issue are more than welcomed to be added in the above table
