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
