I have a small company with 1-5 employees.  I want everyone to share files and access our database.  I am not ready to put my data into the cloud.  I also need to give remote access to some employees.

 

The solution to this problem is to setup a server based wireless network and give remote access to the network using VPN or a Remote Desktop tool.

The server can be setup with enough storage capacity to handle files and the database.  It can also be setup to act as a VPN server to handle incoming cleint remote sessions.  This network will also be connected to the Internet.

A wireless network will be cheaper to setup than a wired one.  A wireless network can also be configured in a fully secure manner to alleviate any concerns about security.

This is an illustration of the solution:
