I like that they are willing to help you with anything related cloud, but also have some very specific skills in areas such as security or network design/configuration which can make things easier when it comes time implement them into your own environment! There's nothing really i dislike about this service so far - everything has been great from their initial consultation right up until now (we've just had our first implementation).
They're able solve any problems we come across during development by providing us access solutions via Amazon Web Services at no cost whatsoever; however if there were something else required outside those services then additional costs would apply depending upon what was needed / requested etc..
