– Kelly Beardmore, Chief Technology Officer and Chief Operating Officer with Tenzing Managed IT Services (www.tenzing.com), says:

Some enterprises are compelled by law to store sensitive data regionally or have information security or operational requirements that preclude, at some level, the use of “shared” network, compute, or storage resources. As a result, service providers have developed niche “cloud” offerings to cater to these requirements. ISVs moving into the SaaS space have the additional complication of re-working their legacy software and business model to fit the new “on-demand” paradigm. The result is a mix of “cloud” solutions from SaaS providers that are multi-tenanted, dedicated, global, and/or regional in nature.
