What you look for in a cloud provider depends to a large extent on the drivers and challenges that you are experiencing.
People with large legacy estates, for instance, tend to be looking for a hybrid cloud solution that can support both their old legacy workloads and their new cloud ones. Some see this as a transitional arrangement to cover the period in which workloads are migrated to the cloud, but many realise that there are certain workloads for which migration will never be either technologically possible or economically practical.
