Diving into the Virtual Pool

It started with server consolidation, and then you know it, it virtualization, and virtualization. Once the server farms into a seamless computing resources, oh, and too useful a layer of abstraction between your computer hardware and software running on, it seems to all: storage systems, network resources, application software development and testing.

Interesting is that this last area - Development - test - this has been proved to be the most Common toe - M processor Water Enterprises entry point for the technology. In the past few years, VMware, vmlogix, virtual iron, surgient, Microsoft and some other virtual driving into the software development life cycle tools to allow developers to work on a single hunk, write code running on the hardware a cornucopia environment, and test source code, it deployment.

Configuration Library virtualization software developers can use the standard x86-based storage configuration for the virtual machine (VM) operating system loaded, the browser and applications. VM container has become a better way to capture the many software configuration. Migrants are highly portable, in a virtual environment, it is relatively easy to move things around in general, to archiving and optimization. Therefore, in issuing the geographical development and testing teams can exchange with each other to complete the environment.

Virtualization also provides a method for testing encountered in the application of heterogeneous enterprises -- different server and client operating systems, databases, middleware and browser. Testing can share complex configuration and wrong, and the tremendous accuracy. And as a new generation of virtual tools that enable developers to focus its resources and to allocate them according to your needs on the basis of immune development manager is increasingly complex, inefficient and costly task, and establish and remove physical development and testing environment.

Virtual wisdom All of these features are the development manager life easier. But they still want to run virtual performances. Here are just a few things, it should be on them to do list: virtual machines, which should be managed in the same way as a physical system. These people containers may be just a pile of files, but if you want your development work in the environment, the boat people in need of repair. Apply to all norms of corporate maintenance practices. Updated operating system, and deploy patches on schedule.

The adoption of best practices for security. Gartner analysts expect the company migrants become acquisition targets of the new security threats, the use of the system because these privileges software layer, if compromise, the local comprehensive workload at risk. This process to ensure that migrants, Gartner said, prior to the start of the deployment of these systems - even in a single vendor or technology choice - to let security, taking into account the evaluation process.

Virtualization solution with, or to allow the construction companies, the Librarys pre-loaded Virtual System Environment , it can be shared development and testing team. These shared library can be configured in just about any combination of hardware, operating systems, service packs, and the application can be imagined. However, fund managers will have to establish a base, a library of images of Vietnamese boat people, and model version of the boat people. Among other things, this will help with troubleshooting, disaster recovery and the Kosovo war disappeared.

Like a physical development - testing laboratories, virtual development and testing environment to separate from the production environment.

Different structure Finally, when people talk about different types of "virtualization, " They re usually refers to the implementation of the abstraction layer Wang Cross-servers, storage systems and networks. But development manager should also be aware of each others differences in the basic structure of the virtual: single operating system image: users process the resources collected by the container. Physical access to the management of resources. This type of virtual scales well, but to maintain segregation in different containers is tricky move.

Totally virtual: the entire operating system and application virtualization as clients operating systems run on top of the host operating system. Allow a single mainframe running many different operating systems customers. This approach raised a level of abstraction to intercept all calls to physical resources.

Prospective Virtualization: the entire operating system running on top of the hypervisor communication and It directly, usually lead to a better performance. Pros: both the operating system and hypervisor-must be modified to accommodate this close interaction.

the advent of tools such as VMware laboratory managers, vmlogix labmanager, Virtual Iron virtual management, have taken the lead industry watchers predict the confluence of the virtual and Application Lifecycle Management (ALM) market. Trend "good sign " wrote IDC analyst and columnist Bill rdn - Carroll ballou "for users to the benefits of virtualization, building software and management software development. "
