AWS is also now offering a blockchain solution, but I really like the way they thought about it. When AWS CEO, Andy Jassy, announced it, he explained how they hadn't seen many uses of a blockchain on AWS that couldn't easily be solved with a database instead. So the solution they developed, Quantum Ledger Database (QLDB), is a cryptographically verifiable transaction log.
ahhaha yes, blockchain as a service
