Conventional wisdom refers to DevOps as a strategy, an approach, or a movement as some call it. DevOps addresses the idea that Development and Operations need to be aligned well in an application lifecycle, work closely and collaboratively to eliminate inefficiency, reduce bottlenecks, and maximize productivity. The concept is certainly not new, for decades business processes and operations based on software engineering concepts or lifecycle management methodologies are all trying to minimize inefficiency and maximize productivity. So what is different now. DevOps in Cloud Computing In cloud computing, infrastructure construction, run-time configuration, and application deployment are now delivered on demand, i.e. as a service, hence IaaS, PaaS, and SaaS. (1, 2) Form an operation's point of view, cloud computing eliminates most, if not all, physical aspects of Dev an... (more)

Windows Azure? What's in It for IT Professionals

Windows Azure relevant to Microsoft private cloud solutions is, in my view, as critical as what Active Directory means to Windows infrastructure. In a Windows domain, Active Directory holds the one version of truth and is the ultimate authority of all resources defined. Similarly when it comes to Microsoft cloud computing, there is no question that Windows Azure is the de facto platform as an extension of Active Directory in the cloud. While enterprise IT is transitioning form on-premise deployment to an emerging architecture of hybrid cloud, IT professionals are facing unprecede... (more)

Understanding Hyper-V Replica

Windows Server 2012 Hyper-V Role introduces a new capability, Hyper-V Replica, as a built-in replication mechanism at a virtual machine (VM) level. Hyper-V Replica can asynchronously replicate a selected VM running at a primary site to a designated replica site across LAN/WAN. Here both a primary site and a replica site are Windows Server 2012 Hyper-V hosts where a primary site runs production or the so-called primary VMs, while a replica site is standing by with replicated VMs off and to be brought online, should the primary site experiences a planned or unplanned VM outage. Hyp... (more)

Understanding Remote Desktop Services (RDS)

In Windows Server 2008 R2 (WS2008R2), Terminal Services (TS) has been expanded and renamed to Remote Desktop Services (RDS). RDS is the backbone of Microsoft's VDI solutions. And in Windows Server 2012, RDS is further enhanced and with a scenario-based configuration wizard. Still the concept and architecture remain very much the same since WS2008R2. The new and enhanced architecture takes advantage of virtualization and makes remote access a much flexible solution with new deployment scenarios. To realize the capabilities of RDS, it is essential to understand the functions of key... (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)
