We currently house all of our GIS data (12 yrs worth) on a server in-house. We do not have arcgis for server. Our company at the suggestion of our IT contractor is considering moving all of our other files and GIS data off-site, so when working on .mxd files we will be accessing data from an off-site server. The reason this transition is being considered is because our company has grown and has several branches in several cities and we have lag times with the DFS servers installed in each office. When it comes to GIS, is this the direction we should go in? Has anyone done this? Any cautionary tales? Any suggestions if we do proceed with this? Should the GIS department not even entertain the thought? Are there any additional software products we will need to invest in to make this happen? I am interested in hearing your opinions and if you have any literature to direct me to that would be great.
