I am not sure if AWS launching a similar service to Traindex is a "milestone" or not . It certainly feels like an important event in the life of Traindex.
I feel a little nervous about the competition, but also excited about the validation. I only have one paying customer. My landing page isn't even ready yet (it's just some generic stuff that needs to be improved a lot). It's safe to assume that AWS already has a lot more traction here.
