More Clouds in the Forecast The migration of vast amounts of data and data processing to the cloud — or more precisely, to clouds — is arguably the biggest change in enterprise computing in the past decade. More and more organizations are moving to public clouds and, more typically, to public-private hybrid data center architectures. At the same time, they are leveraging infrastructure-as-a-service (IaaS) in the quest for ever-greater agility. Technology analyst Gartner projects that the public cloud services market will reach $246.8 billion by the end of 2017, up 18% from the previous year, and that most of that growth will come from cloud IaaS.
The distinction between “the cloud” and “clouds” is not trivial. Increasingly, enterprises are adopting multiple cloud platforms and service providers. One thing is clear: the enterprise data center as a single, secure physical space is headed the way of the dinosaur. The modern data center is increasingly a heterogeneous mix of environments and technologies that combine physical servers, virtual machines and containers in on-premise facilities, private clouds and public cloud IaaS providers. And these disparate installations are not static. Organizations are constantly shifting data and workloads among them as traffic levels and processing demands dictate.
