The data center is undergoing a significant transformation. In the past 15 or so years, data center discussions have been extremely hardware-centric, but as the power of cloud computing comes to pass there is a shift towards infrastructure software. The next-generation data center will be defined by the software that coordinates all of the hardware to achieve a greater level of efficiency. In fact, all of the devices that we have will no longer be directly exposed to business applications. Instead, business applications will be cushioned from the details of hardware by a “data-center-wide operating system” known as Platform as a Service (PaaS), ushering in a true private cloud world.
The past decade of enterprise IT has been driven by Service-Oriented Architecture (SOA) and virtualization. While these technologies have brought great value to the data center and software developers, they have not provided a universal remedy to all that ails enterprise IT strategies. Significant issues still exist, but the recent emergence of PaaS in public cloud and private PaaS as its private cloud sibling, has been touted as the newest technology to revolutionize enterprise IT.
