Online Exams on website: Such institutes can host the software on their owned server in their Lab or on cloud and connected to their website where besides the institute’s regular students, even external candidates can register and attempt the test from home or cyber cafe.
Offline Test in lab: Such institutes can host the software on their owned server in their Lab and keep the access limited on intranet inside the institute where only internal candidates can attempt the test in Labs.
Remember that one License is for one server. If you wish to use the Computer Based Exam in Lab, and also online then you can opt for either of the two approaches:
Remember that one License is for one server. If you have purchased, you can either run it offline on a server inside the lab or online by hosting on the cloud server. The offline server (inside the lab) however can also be made available for online users by certain arrangements. But you cannot install it at two servers and cater offline and online separately.
If you wish to use the same license of the Computer Based Exam System for Offline Tests in Lab and also want to make these tests available to your online users who connect through your website, then you must make following arrangements:
Though the offline server solution works good for the users in the Lab, but making it available for online users through static IP shall have some limitations for the online users. There are no theoretical or conceptual limitations, but practically, a new component "internet" is introduced so it will have its effect if there are any limitations in the upload and download bandwidths of the connection. Making the offline server as online by using static IP method invites internet hassle in some way or the other. Before offline server there was issue for local user to get data from online server, after setting the offline server there is issue to upload data to online user.
As a general scenario, most part of your use is online and less part of the use is offline. Candidates can register online through website. Candidates and parents can access their dashboard anytime for results through online. Some admission leads or visitors to the website would want to take demo tests which is possible only online. Some of the enrolled candidates will also attempt the test from their homes through online server. App is also connected through online. Administrators in different branches can more conveniently work on servers available online like registration of candidates and definition of test etc.
The use and benefit of offline server is limited to conducting test in lab by bypassing the internet dependency and the hosting expense.
The cloud servers do not have limitations in bandwidth and processing (as compared to your local server because cloud servers have virtual scaling of resources and are designed for the purpose. So they are anytime better and well suited for online connectivity than a local server with static IP using shared internet bandwidth.
So it is smarter to maintain the Online functionality for majority convenience and efficiency and use the offline instance of the system for limited functionality to conduct offline test and then revert the data to the Online resource.
The entire activity of administration is done on the cloud instance because it is always online and accessible by multiple administrators in the Lab and also the online users. The purpose of local instance inside the Lab is only for time to time when the test is conducted. The transfer of test definition and the answer data takes place between two servers with a single click of button.
