Ask HN: Small startups how are you deploying and provisioning in AWS?

Hi all, I'm trying to learn more about how small startups are using AWS. I'm particularly interested in: What sort of software you are deploying and how you deploy it (chef, puppet, "by hand" or what not)? How are you provisioning resources in AWS and what those resources are (terraform, cloud foundation, AWS UI)? If you are using a language like Python or Ruby, how are you making sure your dependencies are correctly installed? How do you update them? How large is your engineering team? Do you have anyone who is responsible for maintaining your deployment and provisioning tools? Thanks.
