The term “availability” is a characterization of how reliably a computing system can function and perform the tasks it was designed to run. It is measured as a percentage of time within a given time span (for instance, a year) that your applications are operational and accessible to users. But not all availability is created equally.
Key Benefits
- Backups and restores: Basic backup, data-replication, and failover solutions and procedures are in place to recover services in the event of a failure or disaster. These solutions do not prevent downtime but focus on recoverability which translates into 99% to 99.9% availability. Being down from 8 hours to 4 days can cost from $2M to $23M
- High availability: Typically implemented through clustering, these solution applications are accessible a very high percentage of the time. Users perceive little or no perceived interruption if there is a failure and high availability translates into 99.95% to 99.99% availability. Being down from 1 to 4 hours can cost $230K to $1M.
- Continuous availability: Even if there were to be a failure, application operations are not interrupted. Downtime is eliminated and data is not lost in the event of a failure or localized disaster. These solutions focus on preventing downtime which translates into 99.999% availability. Being down 5 minutes or less, limits your risk to $23K.
