Application Mobility for Business Continuance
Application mobility: Transfer application workloads/virtual machines between data centers, with no service interruption
Business continuance use cases:
Capacity management
Disaster avoidance
Workload redistribution
Data center upgrades

Best Practices
VMotion 5 msec roundtrip latency between ESX hosts
≥ 622 Mbps of WAN bandwidth
Source/destination ESX on the same IP subnet and broadcast domain
Storage High availability to VMs in both data centers Acceptable application SLAs
Network LAN extensions across WAN
High availability–Spanning tree isolation, network loop prevention
Load balancing–Full use of WAN bandwidth
Scalability–Move multiple virtual machines
Routing Optimization–Reach VMs in current data center site
Visibility and Granularity at VM Level–End-to-end consistency across QoS, security, provisioning, and traffic visibility
