My first cloud project

A bit lost on where to start after exploring digitalcoean/aws.

I have looked at the documentation for docker and boto3, and docker seems to be the direction I want to go in (docker for AWS), but I am unsure that these are mutually exclusive solutions.

From what I understand the following workflow is possible:

1. Code local python (most any language, but I am using py)
2. Deploy local code (aka upload) to a server
3. Call that code from a local machine with some argument(s) via a script leveraging some cloud API (boto3/docker?)
4. Grab finished result file from my cloud (pull file that is JSON/CSV etc and contains my results) using an API (boto3/docker?)

I thought this would be way easier to get up and running (maybe it is, and I am just missing something).

I feel like I am hitting my head against the wall on something that is intended to not be so tough.

Any pointers/guidance are hugely appreciated.

Thank you!
