It is important to determine if moving applications or data to a cloud is
simply moving a problem or is an opportunity to improve the overall busi-
ness. It is also necessary to keep in mind that a cloud-based service needs to
make a profit and needs to rely on its own host or managed service provider
to house its service or leverage its own facility including equipment. Its goal
is to keep costs as low as possible, spreading resources across multiple users or
subscribers, which could lead to performance or resource contention issues.
