You should never use products like this where you are completely vendor-locked and will be unable to switch easily to another provider. I did this mistake before and we used SQL Azure Federations (cool & cheap autosharding for SQL Server), then Microsoft decided to discontinue it and provide only very expensive up-scale version of SQL Server instead. We spend months to migrate our product to PostgreSQL... and this is just an example, Google also love to discontinue products, probably even more than Microsoft.
