5. What? Why?
Multiple individual computers Support business needs by avoiding
working together to increase the downtime (increasing availability)
availability (and scalability) of a
clustered service.
Result
+ Complexity
+ Management
+ Cost

7. Management of the private cloud
Hyper-V Platform of the private cloud
Infrastructure of the private cloud

20. Concurrent Live Migrations:
Multiple simultaneous LM’s for
Live Migration Queuing:
a given source or target
In-box tools queue & manage
large numbers of VMs
Storage Live Migration: VHD VHD
Moves VHD’s from one disk to
another
Hyper-V Replica:
Point-in-time replication of VHD’s
for disaster recovery
