AWS is dominant and doing pretty well in the IaaS space, but lack of enough good quality middlewares and enterprise software comparing with its competitors, Azure and Oracle. Maybe this claim is not fair for DynamoDB, Kinesis, Lambda and etc. But these are just managed service. Customers could not get a binary to play around on their own server. So I could not call them software or middleware. So their strategy is simply making the most popular software running on IaaS as a managed service, like managed Hadoop, Spark, K8S and now Kafka... From a customer's perspective, it is pretty good since managed service just works without hassles to manage servers.
