Although cloud computing and virtualization now grab the lion’s share of technology news with promises to revolutionize IT, they also bring many IT professionals a sense of déjà vu. Those who started in the industry before the invention of the vacation condominium are reminded of the time when “timesharing” meant the renting of computing resources through a service bureau. Given the high cost of hardware and relative scarcity of technology professionals, it was an innovative and cost-effective practice. Business users were spared the worries of deployment, provisioning, and maintenance. Infrastructure costs were absorbed by the service bureau and distributed across multiple customers.

Eventually increased computing power, lower prices, and a burgeoning technology workforce set the stage for client-server and distributed computing to replace timesharing and service bureaus. That is, until now. Cloud computing is in reality the timesharing model revisited: it represents a recentralization of computing resources to be shared among different constituencies (whether internal departments utilizing a private cloud or external customers in a public cloud), fueled largely by the capabilities of virtualization technology.

Whereas in the past centralization meant a slice of physical computing infrastructure that was relatively static, today it involves computing resources that are virtualized and extremely elastic. We see an explosion of applications that are becoming ever more sophisticated, and IT infrastructures need to be ever more nimble to handle the volatility that comes with application proliferation. Even though the names have changed, the goal is the same: companies need an IT infrastucture that can provide on demand usage that delivers satisfactory performance and is cost effective. It stands to reason then, that if cloud computing represents the return of a bygone computing model, IT managers can increase their likelihood of cloud computing success by applying some simple lessons from the past.
