There has been a significant amount of hype in the IT space recently about “cloud computing,” Software as a Service (SaaS) and other SaaS paradigms. The notion of on-demand, pay-for-what-you-use resources is an attractive one to already budget-strapped CIOs. With invisible expansion and self-provisioning, cloud computing is a dream come true for the folks with profit and loss oversight of their IT operations. However, not all clouds are created equal.
The strict definition of the cloud isn’t one that can apply to larger implementations yet. It’s very rare that something hitting all the criteria is feasible in the IT infrastructure arena, especially when it comes to security considerations. Throwing in terms like SaaS and others only complicates matters for an already beleaguered infrastructure manager or purchasing agent. When all your company needs is some space to run a mission-critical enterprise class application, Infrastructure as a Service (IaaS) may fill that niche by offering the flexibility of in-house operations with the security and service of outsourcing. Add in the beneficial aspects of the cloud, and you could realize a true win for your IT need.
