@saint Here is some information about Gigalixir database pricing. Moved — GIGALIXIR 1.4.0 documentation
The free database is a Google Cloud Platform db-f1-micro postgres instance described here, but with a 10,000 row limit. https://cloud.google.com/sql/docs/postgres/pricing
Not at the moment, but we’re planning to expand to other regions based on demand so definitely let me know what region you are looking for.
Does gigalixir provide outgoing internet connection? If so, what is the price? Sorry I failed to find info about it.
Of course 
you get one CPU share for every GB of memory. For more see Moved — GIGALIXIR 1.4.0 documentation
Perhaps a better way to say it is CPU is included when you buy memory.
Bandwidth on the other hand is not capped.
