Tutorials Application DevelopmentApplication partitioning is a vital process, as it provides one with the opportunity to clearly define an even distribution of an application’s presentation, process, and key data components – without which, you may find yourself feeling quite lost. The components may be distributed over several different physical machines, or across a vast array of memory address spaces.
Application partitioning serves to maximize the inherent benefits of a multi tiered computer model, in that it distributes application processing across all spectrums of the system’s resources. For those who wish to achieve quality N-Tier distributed computing throughout their Business, application partitioning is a necessary step. How it is done can be critical for the outcome of the N-Tier application.
When it comes to the successful execution of an application partition, the only limitation of the number of tiers is the number of computers available. As the load of processing is theoretically meant to be distributed across a vast array of different processors, the ultimate in N-Tier client server scalability can be attained via the process of application partitioning.
In the past, client server architectures were riddled with numerous problems and limitations. Some of these included a low level of reliability, an excessive amount of clients that resulted in overloading, reduced bandwidth on a network, a reduced level of performance, high maintenance needs, and a low level of flexibility. Application partitioning is a successful way of overcoming all these limitations.
Application partitioning provides users with two essential benefits. The first is that it reduces the amount of turnaround time that is necessary for the data result. At the same time, it decreases the level of network traffic that necessitates the data transfer to the client.
The partitioning of applications is a major void filler when it comes to large scale client server systems. Application partitioning allows for a flexible distribution of application logic, the end result being an optimization of performance.
Of course, a successful application partitioning project is largely contingent on quality tools that will be able to leverage such emerging technologies as object oriented systems as well as peer to peer communications. As a result, better performance, reliability, transparency, and flexibility are all provided for large scale enterprise wide computing systems – in short, a must for any successful Business operating in this day and age.
The partitioning of application provides a client server application development team with sufficient tools needed to support the architecture of an N-Tier application, as well as the capability of constructing an application that is truly distributed.
With the use of application partitioning instruments, the application can be designed on a single client PC machine. Afterwards, parts of it can then be relocated to any server that the network is able to access.
The application should be viewable by developers as a single logical program. The developers should not have to concern themselves with such issues as what components are going to be deployed on clients and what components will be deployed on servers, or whether the machines in question shall be Macintoshes or PC computers.
Once the application has been built and tested, it will be possible to partition it. That should theoretically be as simple a task as merely dragging an application object over to a server icon. Application partitioning tools are then generated and compiled on to native 3GL code in the background on the target servers, which in turn perform the necessary processing.
A client program containing one or more service programs should be the end result.
Such programs are meant to be run on specific forms of hardware, and to also interface with designated software, such as operating systems, GUI, middleware, database management systems, or communications mechanisms.
