Usually, this is available in two versions – ESXi server and ESX server. Basically ESX server is an enterprise level virtualization tool. It makes use of different services which manage multiple virtual machines. Virtual machine A virtual machine (VM) is a software-based emulation of a computer. Virtual machines operate based on the computer architecture and functions of a real or hypothetical computer. Definitions[edit] A virtual machine (VM) is a software implementation of a machine (e.g., a computer) that executes programs like a physical machine. Virtual machines are separated into two major classifications, based on their use and degree of correspondence to any real machine: A VM was originally defined by Popek and Goldberg as "an efficient, isolated duplicate of a real machine".
Converged Infrastructure Converged infrastructure is used by IT organizations to centralize the management of IT resources, consolidate systems, increase resource utilization rates, and lower costs. These objectives are enabled by the creation of pools of computers, storage and networking resources that can be shared by multiple applications and managed in a collective manner using policy driven processes. IT vendors and industry analysts use various terms to describe the concept of a converged infrastructure. These include converged system, unified computing, fabric-based computing, and dynamic infrastructure. Service-oriented modeling and architecture How to identify, specify, and realize services for your SOA Ali ArsanjaniPublished on November 09, 2004 There has been a lot of buzz and hype -- some factual, some not so well-founded -- surrounding the opportunities presented by Service-oriented Architectures (SOA) and its implementation as Web services. Analysts have predicted, pundits have professed, professors have lectured, companies have scurried to sell what they had, as SOA products -- often missing the point that SOA is not a product. It’s about bridging the gap between business and IT through a set of business-aligned IT services using a set of design principles, patterns, and techniques.
Block vs file level storage, VMware VMFS, NTFS and some of the protocols involved. During the past few months I have spend a considerable amount of time looking at various storage related topics. Among others I discussed Web Scale technology as part of converged and software defined architectures, with Nutanix being one of the main vendors, next I also took a, somewhat, deeper dive into the wondrous world of IOPS where I talked about some of their characteristics and ways to potentially enhance performance and the end user experience, which are still two of the main concerns when dealing with these bad boys. Throughout this article I want to take a closer look at some of the differences between block vs file level storage, the accompanying file systems, the different protocols used, potential block sizes and some of the characteristics of VMware VMFS in particular. Key components DAS, SAN, NAS, converged
Software as a service According to a Gartner Group estimate, SaaS sales in 2010 reached $10 billion, and were projected to increase to $12.1bn in 2011, up 20.7% from 2010.[6] Gartner Group estimates that SaaS revenue will be more than double its 2010 numbers by 2015 and reach a projected $21.3bn. Customer relationship management (CRM) continues to be the largest market for SaaS. SaaS revenue within the CRM market was forecast to reach $3.8bn in 2011, up from $3.2bn in 2010.[7] Chapter 1: Service Oriented Architecture (SOA) “SOAs are like snowflakes – no two are alike.” - David Linthicum Consultant Getting Started with Hyper-Converged Storage What's yours is mine: Sharing DCIM Maximize the potential of DCIM tools by bringing facilities and IT together.

Cloud computing Cloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud. Cloud computing is a computing term or metaphor that evolved in the late 1990s, based on utility and consumption of computer resources. Cloud computing involves application systems which are executed within the cloud and operated through internet enabled devices. Purely cloud computing does not rely on the use of cloud storage as it will be removed upon users download action. Baby Steps to SOA – Step One: Analyze and Plan In the continuing Baby Steps to SOA series, we follow Doug and his IT team behind BuyMyWidget.com as they take steps to renovate their digital asset architecture. Previously, we introduced the problem and the team, and now we start on our travel through the road map. The Evolutionary Roadmap
Group Policy - GPResult Examples - The Sysadmins GPResult is a command-line utility for determining the resultant set of policy for a given user and/or computer. In other words, it shows you what Group Policy Objects have been applied and their settings. This is typically one of the first tools I go to when troubleshooting Group Policy from a client once basic connectivity has been confirmed (e.g.
Velocity (software development) Velocity is a capacity planning tool sometimes used in Agile software development. Velocity tracking is the act of measuring said velocity. The velocity is calculated by counting the number of units of work completed in a certain interval, the length of which is determined at the start of the project.[1] Enterprise architecture framework An enterprise architecture framework (EA framework) defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers or views, and offers models - typically matrices and diagrams - for documenting each view.
Multitier architecture In software engineering, multi-tier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing, and data management functions are physically separated. The most widespread use of multi-tier architecture is the three-tier architecture. N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific layer, instead of reworking the entire application. A three-tier architecture is typically composed of a presentation tier, a domain logic tier, and a data storage tier.
SOA (service-oriented architecture): An approach to building applications that implements business processes or services by using a set of loosely coupled black-box components orchestrated to deliver a well-defined level of service.
