Server Transfer

JavaScript and Ajax based applications will always be on the client side. The efficiency of JavaScript and its appeal to users worldwide is largely based on its ability to update specific parts of the webpage. It's also the increasing choice of many developers because of the increasing library and frameworks that supports the programming language. As a tool for developing online applications, JavaScript has practically changed the way users interact with their browsers.

But even though most of the functions in JavaScript and Ajax is implemented in the client side, it still needs a server to run. In fact, the application will not work as expected if the server was never optimized for client side programming. Developers need to choose a highly reliable server in order to implement an efficient application.

With that said, server transfer for JavaScript is a very delicate process for developers. Transferring data from one server to another is usually a very simple task especially for HTML based web pages. However, JavaScript requires additional consideration in order for the online application to work well without additional challenges during transfer.

Working with Massive Data

The biggest challenge for developers when transferring servers for JavaScript is on how the massive data will be transferred from one server to another. Of course, this problem will not happen if you're developing a small application. But Ajax and JavaScript based applications often have to deal with massive functions that comes with the data. Since the server will have to be changed, the destination will have to be changed as well. You have to make sure that the codes in the application points to the right destination.

Working with Secured Webpages

Another challenge that developers have to face when working with changing servers in the application is the secured webpages. One of the best security features of JavaScript application is when the secured webpages will have to be run from specific locations. This prevents intrusion from external sources. While this technique provides a highly efficient security features, it's a disadvantage for developers who wanted to change servers.

Dealing with this problem is no easy task but can be done. The developers may have to change the root of the coding to point to the specific IP as well as update their system that checks the security protocols. The secured webpages, especially with log-in webpages can be especially challenging since it will require additional updates on the log-in functions.

System Down when All Else Fails

Changing your system is not an easy task since there are too many things that needs to be updated and changed. This process might require additional manpower, funds and time.

The required time in updating the application when changing servers can actually force developers to shut down the website for a few days. This is a very big decision for developers and the site administrators. When this is required, additional planning as well as user updates have to be implemented. System down can mean disappointed users. For that reason, careful planning has to be implemented before any server change for JavaScript and Ajax based applications.
