I am looking to host a booking application that if it went down for any long length of time there could cause massive disruptions to business operations for our users. Are there any good quality hosting solutions that offer redundancy as a package? Or what host offers the best availability (99.99)?
We don't have a huge budget and understandably we can't expect availability near the five 9's without paying for it. We could at the very least make do with hosting that doesn't go down for maintenance work.
Thanks for any suggestions.
