Disaster recovery represents an innovative application of
virtualization technology. Traditionally, disaster recovery has been
achieved through the use of redundant infrastructures and systems
housed in remote locations, away from primary datacenters. While an
effective strategy, many IT organizations find it difficult if not
impossible to buy and maintain “two of everything.” …Neither virtualization nor virtualized DR is a panacea. Rather, they
are complex initiatives requiring careful, ongoing consideration of key
issues, including:
- Increased criticality of virtual servers
- Increased complexity for server administration and management
- Change management and architecting the infrastructure migration from physical to virtual environment
- Balancing investment versus higher utilization rates
- Need for new skill sets and processes
