TABLE 6-1 Cloud Computing Pros and Cons

Auditing
Organizations must have backup and recovery plans for their IT assets.

Assets include business-related data, network infrastructure, exit strategies,
and so on. If any of the assets fail, how is service restored? On the surface,
the risk of hardware failure appears to be transferred to the cloud provider.

However, the service level agreement (SLA) offered by a provider, as
pictured in Figure 6-1, may not be adequate for the business.
In some cases, the SLA can be negotiated such that both parties will
benefit.

FIGURE 6-1 The provider-supplied SLA may not be acceptable to your
organization.

Security
The classic security architecture revolves around a single point of defense

that separates company assets from the outside world, that is, the Internet.
