That is definitely part of the problem, they should have forced a multi cloud solution. Bring at least two vendors in, and make them compete and keep eachother honest. Either way, you need to keep the around for years, so you have time to get things set up to meet the security standards, migrate apps to the cloud(s), and all that. A 10 year contract does make sense as far as not having to keep redoing things. But as it is, that will end up a much longer contract due to vendor lock in.
