Cloud computing success

Key concepts

· Reliability – reliability of the system, measured in Mean Time Between Failures (MTBF)

· Availability – uptime of the system or application, measured in parts per million (PPM) of downtime

· Serviceability – easily restoring the system after a failure, measured in Mean Time To Repair (MTTR)

· Manageability – the ease with which the entire system can be managed, measured in systems per headcount.

· Scalability - the ability of an information system to be used or produced in a range of capabilities

· “Updatability”– a key factor linked to performance, integration with other IS and security
