We had the same experience when starting to use AWS/Azure. Our in-house team was all experienced with using VMware on-prem, with some mainframe and a few legacy physical servers. So we had a broad depth of knowledge for running our own datacenter. So when we started using AWS, we really made a lot of mistakes by trying to replicate how we did things on-prem. And there was a lot of resistance to using cloud services; some people viewed it as a threat to job security. Others simply had a difficult time adjusting to the change in operations/procedures and philosophy. This held us back quite a bit until we hired a few contractors who helped us better understand where we needed to change, which features worked well in the cloud (and which sucked). We brought the best contractors onboard as FTEs, and it's been a much better experience.
