The concept of application virtualization is simple in nature but more dif?cult in imple-mentation. Effectively, all the words application virtualization mean are that an application can be installed on a server and be dynamically accessed by a user without needing to install a program or any other additional software. Instead, the application is run off the server in a dedicated server space. This allows for fewer user connections, more ?exible deployments, and great cost reduction in terms of licensing, time, and technical dif?culties.
For an application to be ?virtual,?it has to exist MCSE somewhere other than on the primary operating system that resides on the user?s computer. In the Windows enterprise environ- ment, this means it can exist in several places:
Locally A locally installed virtualized application is an application that is installed only on the host-based computer. Normally, this occurs through the use of other virtualization technologies, such as VMware or Microsoft Virtual PC.
Web-based Web-based virtualization refers to any implementation of virtualization that allows clients to access an application remotely via a website URL. This includes technolo- gies such as TS Web Access. When this is in use, the user installs no local software; instead, the application is run purely on the server side and is contained within an Internet browser.
Remotely When an application can be accessed only remotely, it exists somewhere between the realms of locally installed and web-based. It isn?t accessible via the web browser, and the client doesn?t have the application installed on the host machine, but the client does have a Configuration installed that allows it to access the remote program, which is accessed via IP packets across the network.
You can be pretty darn thankful for some serious improvements A+ Exams over the years in both the design and implementation or programs that make it unnecessary for you as an administrator to understand every single aspect of a program. In the ?old days,?when custom applications were made, teams of engineers would spend hours, days, months, or even years trying to create a system that would allow multiple users to access a program. They would create a program by hand from the ground up and then put it in a place that could be accessed by everyone in the organization at the same time, which wasn?t easy. This is because a pro-gram might comprise one of two types of ?libraries??static libraries (libraries (.dll).lib) and dynamic Static libraries A static library is a collection of classes, compiled objects, and executable code that has been created by a compiler for instantiation in a program in one area. In simpler terms, it’s a collection of code that is used for one place at one time. At the enterprise level, you won?t normally deal with this type of library. However, it’s useful for understand – ing the next type of library, which is much more important?dynamic link libraries.
