Im a consulting for a School IT support company and have been tasked with implementing a system for a school in Bedfordshire in England. I'm not sure which works out best for a school setup. I know that RDS relies on one server or farm of servers using DNS round robin to work. But I'm leaning towards VDI. When it comes to the VDI I would like to know what the best means of making the VDI in the pool collection highly available. Do I build another VDI server on a different node and how do I trigger the failover?
