As organizations become more dependent on their information systems, they begin to look for ways to make those systems more resilient. Data center managers have used focused on high-availability architecture for years, but the industry transition to virtual data centers has caused organizations to rethink their high-availability strategies. More on high-availability architecture High-availability guide: Using high-availability servers and systems Symantec, VMware team up for virtualization high availability High availability provides disaster recovery for day-to-day emergencies One of the most interesting aspects of the shift to virtual data centers is that even small organizations that may never have used a clustering strategy are now almost forced to deploy some form of high-availability architecture. That's because smaller organizations often treat virtualization as a means to save money through consolidation. But as organizations consolidate servers, they also consolidate risks. For example, an enterprise may not consider ...
Features in this issue
Hardware purchases remain flat as virtualization spending and deployments show steady growth.
IT process automation tools help tackle workflow challenges in virtual machine management, disaster recovery and server consolidation - and free up IT staff for higher-level virtualization projects.
If you're getting more involved with virtualization, you may want to take another look at your high-availability architecture. Redundancy and abstraction can help prevent problems.
