Hi @Tarique
AWS is a Cloudera partner and we have many customers (including some of my own) happily running Cloudera on AWS infrastructure.
When designing an architecture it is best practice to define a set of overall principles that define what that architecture is designed to achieve. I would say that it is a very good architecture practice is to design for a loosely coupled and modular architecture. What I mean by this is that you have flexibility in your architecture design that does not lock you into one way of working - either now or in the future.
When you deploy Cloudera into AWS you are essentially decoupling the infrastructure layer (AWS) from the platform layer (Cloudera). Cloudera supports using S3 and EC2 instances at the AWS infrastructure tier no problem. But we also support the other public cloud providers too. This means that you can also deploy Cloudera into Azure or GCP i.e. you are not locked into using a single cloud provider now or in the future.
Indeed you can use the Cloudera platform on-premises, in AWS, in Azure or in GCP i.e. with this approach you have the flexibility to work across on-premises deployments and different cloud providers (including a hybrid approach). Cloudera even provides software in the platform to move data from one infrastructure provider to another.
Almost all of my customers have adopted this multi-cloud approach to avoid the 'lock-in' scenario to a single cloud provider. Take a look at this article for example: Why Organizations Choose a Multicloud Strategy
Also, I don't agree that the services are the same between Cloudera and AWS. Yes, there is some commonality with the open-source projects but there are also big differences at the platform level. It would be too much detail to go into here.
Finally, Cloudera is a 100% open source company with a big commitment to the upstream open-source projects. We recently reaffirmed this commitment in this article: Our Commitment to Open Source Software. I would encourage you to investigate the AWS approach on this topic.
I hope I have given you some food for thought but ultimately, I agree with the reply from @GangWar; if you reach out to our sales team, one of our Solution Engineers can go into this in a lot more detail with you.
Regards,
Steve
