Cloud computing offerings started on public clouds, but aren’t limited to them. Establishing private clouds is one of the most important current trends to modernize enterprise IT. Organizations are looking at private clouds as an approach to protect their investments and control core assets while taking advantage of cloud technologies. Another motivation for the increasing popularity of private cloud solutions among larger IT organizations are enterprise requirements, which often exceed the functionality offered by public cloud providers and their standard services, especially in areas such as security and compliancy, reliability, control and customization. …

Every device connected to the Internet—such as your smartphone, computer, tablet, even certain high-tech household devices—must be assigned an IP address for identification and location addressing in order to communicate with other devices. With the number of new devices being connected to the Internet rapidly increasing, it’s no wonder IPv4 addresses were predicted to run out.  …

The power of High Performance Computing (HPC) is well-established, whether it’s being applied to weather forecasting and climate analysis, genome modeling and analyses of neuron function, or material modeling for new generations of semiconductors. But when we think of HPC, we think of supercomputers, colleges, universities and research institutes. IBM has always been a major player in this space, which is why the recognition of Sequoia, the IBM Blue Gene/Q system installed at the Lawrence Livermore National Laboratory in Livermore, CA, for the Department of Energy, as the number one ranked supercomputer in the world came as no surprise.

Of more immediate interest to enterprises, however, is the fact that IBM, with the finalization of its 2012 acquisition of Platform Computing, has moved aggressively to create an HPC solution capable of scaling to the needs and budgets of enterprises. Earlier in 2012, Helene Armitage, general manager of IBM Systems Software, said that: “The acquisition of Platform Computing will help accelerate IBM's growth in smarter computing, a key initiative in IBM's Smarter Planet strategy, by extending the reach of our HPC offerings into the high growth segment of technical computing ... . Our intent is to enable clients to uncover insights from growing volumes of data so they can take actions that optimize business results.”…

I’m not a fan of clouds. I bristle when I hear the term used. It has become a fetish in business circles where non-technical managers speak of clouds to mask their lack of knowledge of the black arts of IT, and it’s a fixture in vendor marketing brochures, where it satisfies the dual criteria of marketecture: It sounds technical but means whatever a vendor says it means…

Many large organizations are implementing private clouds to enable on-demand network access to a shared pool of computing resources they can easily and quickly configure and provide. Although the main focus of cloud computing has been on the distributed infrastructure, organizations have learned that the zEnterprise also works well for implementing private cloud using Platform as a Service (PaaS)…

Ask people about their IT strategy and you often get a long answer. I’ve looked around a bit, and the definition that appeals to me most is one I found on the CioIndex Website at www.cioindex.com: IT strategy is an iterative process to align IT capability with business requirements. The author adds a few extras to clarify this succinct definition:…
