This document discusses centralizing NID's main applications with failover capabilities. Currently, the applications are installed individually on each client, requiring lengthy manual updates. The proposed plan centralizes the applications on virtual servers with failover, allowing installation to be done once. This will save significant time during updates, provide consistent versions across clients, and introduce high availability through the failover servers. The new setup aims to improve the application management process.

Total Client installed the NID Apps 30 Client.
The time calculation:
= 20 minutes x 30 client
= 600 minutes (10 hours)
for 3 application = 30 hours*

8. The Benefit for Centralized the NID Apps
o Installation/Update system only 1 times
o Saving time for installation/upgrade
process
o All client will be accesses same
application and version
o Easy for end-user, the shortcut apps
will be show on desktop automatically
o Zero downtime;
The system using failover server, if the
Apps server down (restart/update)
another server will takeover the Apps
system
