In today's cloud computing deployments, especially with systems like Amazon's EC2, the users' application is responsible for both measuring and taking action on application performance issues.

Two nines is the same as 99%, which comes to (100%-99%)*365 or 3.65 days of downtime per year, which is typical for non-redundant hardware if you include the time to reload the operating system and restore backups (if you have them) after a failure.
