From the previous company where I worked, they have implemented the use of remote access software. These will allow programmers to access inter-branch computers by means of remote access and management tools installed both from main office and branch computers.Anyway, they have used a lesser brand but in the market on remote access technology, SSH Telnet of Pragma Systems is the leader. Their software has been used majorly by most Fortune 500 companies in the US. Most leading companies who used such remote access technology are Coca-Cola, HP, Dell, Motorola and more.
This technology is far the best used in terms of communication business solutions. It has helped many companies lessen expenses related to travelling and programming updates.
