This is not a big deal, certainly not worth tweeting about. There are hundreds of thousands of AWS partners. It pretty much means you use AWS cloud products, which in itself removes the integrity of an app being decentralized as a centralized organization would need to pay for usage. I worked for Centrality briefly and I believe they are a long, long way short of having the expertise to deliver what they believe they will. Tweeting about a working product or feedback from early adopters, that could be worth a tweet for investors but being an AWS partner?
