There's room for startups to wrap these services into something more usable. There are already good examples: netlify, graph.cool, dashbird and others.
The AWS web console is terrible UX/UI, and when they do update an area, eg s3 they almost make it worse.
Please hire a few of the best UX/designers you can an do a top down refresh of the AWS console with consistent navigation.
I am moving new and existing projects to Google Cloud based on the some slight different product offerings, sustained use discounts, and in very large part on the better web console.
All I can say IRT this is WOW. The Google web console is one of the most painful UX experiences I've had in this space.
Most of the console feels to me like the people who build it don't actually use it.
The value proposition here is incredible, you can save so much money for companies.
At my previous company, I changed one of the data ingestion architecture and saved 250,000$ in YEARLY AWS bill.
Of course, there are many problems with this, but I still think there is room for this. Right now, this knowledge is in silos in companies. Lots of companies should benefit from this.
AWS provides great building blocks but using them efficiently is a major challenge (especially for smaller teams). Like in your case, there is an enormous potential in better resource utilization!
I mean most of these APIs are more like RPC than REST.
This is a classic service company, but the service it provides can be quantified and measured in a great way
