Amid the many benefits of having the NIST SP 800-145 as a tool to facilitate the understanding of cloud computing, the classification and some definitions of the four deployment models are redundant and inconsistent. Particularly, the definition of "community cloud" is a redundancy of that of a private cloud, the deployment models are defined with two sets of criteria, and "hybrid cloud" is a confusing, ambiguous, and extraneous term. SP 800-145 is the de facto standard in the IT industry of describing what cloud computing is with five essential characteristics, three delivery methods, and four deployment models. The five essential characteristics will specify the qualifications and expected behaviors of an object qualified with the term cloud. The three delivery methods signify the essence of cloud computing centered on the concept of a "service." Both the character... (more)

Cloud Computing Goes Far Beyond Virtualization

Virtualization vs. private cloud has confused many IT pros. Are they the same? Or different? In what way and how? We have already virtualized most of my computing resources, is a private cloud still relevant to us? These are questions I have been frequently asked. Before getting the answers, in the first article of this two-part series listed below let's first go through a few concepts. Part 1: Cloud Computing Goes Far Beyond Virtualization (This article) Part 2: A Private Cloud Delivers IT as a Service Lately, many IT shops have introduced virtualization into existing computing ...

Infrastructure Was Then, Private Cloud Is Now and Beyond

Seven years of research with 15,000 data points, as shown below, provides overwhelming evidence that there is a noticeable increase in efficiency with a significant reduction of TCO by moving IT from Basic intothe  Rationalized stage in the IO (Infrastructure Optimization) model. And cloud, or more specifically private cloud computing, offers a roadmap to facilitate enterprise IT transforming from Basic or Standardized into Rationalized. A transition from a traditional infrastructure-focused deployment model into a cloud-ready, cloud-enabled, and service-centric delivery vehicle ... (more)

From Bare Metal to Private Cloud, System Center VMM 2012 Delivers

Today cloud computing facilitated by virtualization continues emerging as the service delivery vehicle for IT to shorten go-to-market while facing unpredictable data patterns and workloads. The increasing complexities and growing user expectations make system management on the center stage of a cloud computing solution. In addition to automation, we now need a self-service model to fundamentally reduce the cost structure of required training and on-going maintenance. Besides processes and procedures, we now need work-flows and orchestration. The requirements for a management so... (more)

Getting Productive with Windows Server 2012 (Part 3)

This is the last article of my 3-part blog post series for facilitating experienced Windows system administrators to get productive on Windows Server 2012 with a keyboard and a mouse as the input device. Part 1 and Part 2 are focusing on basic user operations with the new Metro UI. To conclude the series, here are two important facts that one should know when running Windows Server 2012. Again, I want to underscore that Windows Server 2012 is designed with cloud computing in mind, and together with System Center 2012 as the foundation of Microsoft private cloud solutions. For th...
