A non-technical challenge in cloud computing is related to contractual
issues, that is, service level agreement (SLA) disputes between
client and vendor. Since clients depend heavily on vendor’s technology
to run business and process data, a fully agreeable contract (including
SLA) must be created and signed. Namely, SLA must include
performance measurement, security provisions, service charge amount
and metering method, exit strategy (how to terminate contract), etc.
Therefore, SLA is a key objective to be audited.
