Executive Summary

  • This book covers hardware and the changes that are occurring to cloud commodity servers, on-premises proprietary servers, mainframe, and appliances like Oracle Exadata and how this is enabled by open source.
  • Open source gets less of the focus in IT media but is critical to the changes in the public cloud, but is driving change behind the scenes.

The Public Cloud Revolution: How Open Source is Displacing Proprietary IT Mega Vendors

The Book on the Primary Driver of Open Source

Everywhere one looks open source is driving change in enterprise software. The ascendant cloud service providers like AWS and Google Cloud have leveraged open-source software and hardware to create hyperscale environments that the proprietary software vendors will find very difficult to replicate. This book tells the minimally-told story of how exclusive software and hardware vendors overstate their innovation, seeking to be compensated for their claimed IP, rather than their real IP. And how quietly, open-source projects have lead to driving some of the most critical changes in computing.

The Book on How Open Source Drives the Cloud

Open source projects ranging from the well known Linux OS to PostgreSQL to lesser-known projects like The Open Compute Project are increasingly providing the most stable and foundational elements to the Public Cloud. IBM is attempting to piggyback on this reality through their acquisition of Red Hat. But in the coin-operated IT media coverage, it is the private vendors that steal the spotlight from these open source projects. This book, devoid of any vendor funding, focuses on the impact of open source and how it is undermining the claims made by commercial vendors.

The Book on the Ability to Move Away from Proprietary Hardware

This book compares four different hardware modalities, commodity (open-source specification) servers for cloud service providers, on-premises proprietary servers, mainframes, and appliances. And it explains that in all but one of the modalities, mainframe (which has now embraced Linux), the role of proprietary hardware vendors will decline into the future.

A Book Based in Reality

Currently, to get business, many companies are making migration appear more straightforward than it is. This book is not about marketing or getting people in a lather open source or cloud services. A significant component of the book explains the central and overlooked importance of the mainframe. Instead, the book provides many examples from real-life project experiences, the emphasis being on the reality of these projects.
