An interesting topic that came to our attention is how to migrate VMware vCloud Director® vApps from one distributed virtual switch to another. Recently, from the experience of one of our field consultants, Aleksander Bukowinski, we received a detailed procedure to overcome the possible service disruptions due to such a move. Aleksander has also authored a whitepaper on this topic that will soon be available for our audience in VMware Partner Central. The paper also covers in detail an additional use case with Cisco Nexus 1000V and provides PowerShell and API call samples.
Depending on connectivity mode, we can have five different types of vApps in vCD: directly connected, routed, connected to routed vApp networks, isolated, and fenced. The migration process would not require shutting down the vApps while the migration happens, but rather could generate brief network outages in case the VMs are connected to a vCloud Director Edge Gateway, or no outage at all if the VMs use isolated networks with no dependency to the Edge.

VMware vRealize Operations™ is a key component of a vCloud Air Network powered cloud service offering. It provides a simplified yet extensible approach to operations management of the cloud infrastructure. It helps service providers maximize profitability by optimizing efficiency and differentiates their service offerings by increasing customer satisfaction and delivering to SLAs.
VMware vRealize Operations also enables service providers to generate new revenue streams by expanding their footprint to offer VMware vRealize Operations™ as a service to give their tenants a deeper insight in to the health, capacity and performance of their hosted environments.
This can either be delivered on a dedicated per-tenant basis as part of a private cloud solution offering alternatively the vCAN Service Provider can offer a shared vRealize Operations™ platform as a managed service.
In this scenario, the service provider operates a centralized vRealize Operations Manager instance to collect all data generated by the resource cluster. Both service provider personnel and tenants will access the same instance of vRealize Operations, and data access will be controlled with RBAC. This scenario allows for easy management and deployment.
This approach is especially attractive for service providers who can operate their complete environment within one vRealize Operations Manager environment.
Advantages include the following:
- Easy to deploy and manage
- No additional data/configuration distribution for dashboards, policies, and so on is needed
- Only one instance to maintain (software updates, management packs, and so on)
Disadvantages involve the following:
- Role-based access control requires careful maintenance
- Objects can only be operated under one policy, removing the ability to limit alert visibility for a customer/tenant
- Sizing can get complex and larger environments could be limited by sizing parameters. A possible workaround could be to build instances per larger resource group.
This is just one way a vCloud Air Network provider can differentiate their service portfolio with vRealize Operations™ by extending the consumption to your end-customers as a managed service.
