Availability
- OK, what makes High Availability?
- Don't lose my data.
- Even if something goes wrong, guard my data. A backup may be sufficient.
- Don't lose my service.
- OK, the box crashed, or a disk died, but you better not be out of action for long.
- Don't lose my service, I mean it!
- So what if the machine was struck by lightening? Surely there is another copy running somewhere?
