Hyper-V over SMB

Hyper-V over Server Message Block (SMB) signifies a newly emerging trend of cost reductions on storage hardware and a progressing standardization of storage virtualization solutions. In Windows Server 2012, an SMB file share can now store virtual machine (VM) and SQL Server resources in addition to traditional end-user files like office documents. SMB protocol is a network file sharing protocol allowing applications to read and write to files and requesting services from server programs in a computer network. Windows Server 2012 introduces the new 3.0 version of SMB protocol. A W... (more)

An Inconvenient Truth of the NIST Definition of Cloud Computing

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 m... (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 ...

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)
