Subject [jira] [Commented] (CLOUDSTACK-5567) enable VPC at region level
Date Fri, 06 Jun 2014 05:08:02 GMT


Murali Reddy commented on CLOUDSTACK-5567:

Region level VPC, will work only with overlay networks. VLAN's can stretch across zones, so
with VLAN's region level VPC is not possible. Right now in 4.4 release, only OVS enabled zones
are supporting this functionality, but its possible other SDN solution integrated in CloudStack
(for e.g, VMWARE NVP/NSX, Contrail) can be extended to support the functionality.

> Currently VPC in CloudStack is a zone level entity. So tiers with in the VPC are confined
to the zone to which VPC belongs. For an application deployed in current model of VPC failure
of the zone is a single point of failure. It is desirable to make VPC a region level entity,
where tiers in the VPC can be created in different zones of the region. When tiers can be
created in different zones, application hosted in VPC can be architected to be highly available
masking zone failures by having redundant tiers in different zones.
> This enhancement targets only VPC tiers built with overlay networking.
