Today the data center is evolving, there are numerous emerging technologies, endless blogs, editorials and other commentary on some form of [INSERT YOUR FAVORITE] computing technology. While the terminology is often alien, the underlaying technology is very familiar to every IT professional. Those familiar technologies are the building blocks for the next generation data center. Whether its Unified Computing, Cloud Computing, Utility Computing or Grid Computing that is the flavor of the month, those building blocks are unlikely to fundamentally change. Each of these computing models needs storage, networking, compute and virtualization technologies. How those technologies are integrated together, deployed and managed may change, but the core technologies themselves are still needed
This publication focuses on those core technologies, the open source projects that provide and augment them, and the unique ways to leverage those technologies in your production environment. The public cloud services that are available today are built on top of open source technologies, innovative projects such as Eucalyptus and KVM are enabling the private cloud, and other next- generation data center solutions. Each month this publication will take an in-depth look at Virtualization, Storage, Compute / Applications, and Networking technologies in dedicated columns. In addition to these columns, a monthly feature article will explore and explain a related emerging technology.
This publication is targeted at Information Technology professionals. If you are currently (or plan to be) involved in Business / Enterprise grade Information Technology solutions, then this publication is for you. Whether you are the technical lead at a startup, system administrator at an established business or the CIO responsible for a multi-million dollar budget, this publication is designed to save you time byproviding focused and factual technical information on open source solutions.
In this inaugural issue, the Virtualization column takes a look at KVM, the Linux Hypervisor that for many is the emerging de- facto virtualization platform. This months storage article introduces iSCSI and examines the necessary steps to get it running in Linux. The compute column examines Puppet, an open source project designed to facilitate configuration management on large numbers of servers, whether physical or virtual. Following several interesting conversations with a number of technical trainers, it is clear that a large number of IT professionals responsible for small and medium sized business networks are unaware offundamental IP data network concepts. The networking column looks at several best practices when deploying basic IP data networks to lay the foundation for tomorrows larger corporate networks.
The feature article this month takes a high level look at hypervisor and cloud technologies. What exactly is a cloud, do you need a private or public cloud, what are the benefits and how do these technologies tie in with technologies such as Unified Computing, are just some of the questions we try to answer.
