Costs of Hosting
Question 1: What's the current cost committed to hosting?
Question 2: What are our needs going forward?
Justhost suggests that our mean bandwidth is 110GB per month (min 80GB, max 130). At standard S3 rates this 2.3USD per month so probably not going to break the bank, and even if we become 10 times more popular it would be affordable.
Netlify has a free tier (seems ok) and an expensive paid tier (45USD p/m). What does the paid tier get you?
Might be fine to go with the free tier for the static page and pay for proceedings traffic directly on AWS. Not sure if that works, so will have to try.
