Split site schools, what is your MIS solution?
In September 2014 we are going to close both our catholic Bradford schools and re-open as one school operating on a split site, KS3 on one site and KS4 + 6th form on the other. The schools are 1.2 miles away from each other and I am wondering if there is anyone on here who operates an MIS system in a similar scenario (we use SIMS) - the solutions I have been looking at so far and their disadvantages are:
Cloud based database - Data held offsite, relies on our internet connection
VPN with backup adsl - One site will suffer slow connectivity, reliable on internet connection
Ubiquiti Airfiber - requires radio mast at each site (planning permission involved)
Dark Fiber lease - about £7k per year in line rental
Install new dedicated fibre - need to dig up the road, estimated cost £60k-£80k
Any advice would be appreciated
