Just as large Internet service providers use multiple network providers so that failure by a single company will not take them off the air, we believe the only plausible solution to very high availability is multiple Cloud Computing providers. The high-availability computing community has long followed the mantra “no single source of failure,” yet the management of a Cloud Computing service by a single company is in fact a single point of failure. Even if the company has multiple datacenters in different geographic regions using different network providers, it may have common software infrastructure and accounting systems, or the company may even go out of business. Large customers will be reluctant to migrate to Cloud Computing without a business-continuity strategy for such situations.
