The move to the cloud represents one of the largest paradigm shifts to ever affect IT. More than just a simple technology evolution, the cloud fundamentally changes many of the cornerstones on which IT evolved. From redefining the concepts of operating systems and middleware, to revolutionizing the way IT services are built and consumed, the cloud is ushering in an era of change unlike any we have ever seen.
In Part 1: The Industrialization of IT, Sacha examined the evolution of electricity and the development of standards for operating and using it. He then compared the evolution of grid delivery, instant-on access and pay-as-you-go models in the power industry with the parallel evolution occurring now in IT service delivery.
In Part 2 (below), Sacha takes a closer look at Infrastructure as a Service (IaaS).

- Part 1, The Industrialization of IT, Sacha compares the evolution of electricity and its delivery with the evolution of IT. He draws parallels between the instant-on access and pay-as-you-go models in the power industry with the evolution occurring now in IT service delivery.
- Part 2, The Irrelevance of Infrastructure as a Service (IaaS), see above
- Part 3, The Death of Operating Systems (as We Know Them), Sacha talks about how the operating system will evolve under the new IT service paradigms
- Part 4, The Death of Middleware, Sacha looks at the impact of PaaS on traditional middleware
