Its all about uptime!
System uptime and availability is being increasingly important. Various services are expected to be accessibly at all times. The challenge is to configure and maintain such a system, with minimal downtime, and preferable no downtime at all. At first this sounds like a very complicated task, but breaking it down to its components makes it possible.
These are our worst foes
Deciding the level of importance of the system really depends on the physical environment. As we can see there are
- Power outage
- Internet access
- Hardware malfunction
- Software updates
To get around this a redundant system has to be built. Realizing that a redundant system consists of many redundant parts, virtualization naturally comes to mind.
Configure your system
Manage Virtual Domains
Network Planning
