I feel like AWS/cloud would be more in house, though it's more a trust issue than anything else. Infra is the backbone of a company, and something some people wouldn't trust to a part time freelancer. Or someone laying on a beach in Bali might not be so accessible in the 0.1% of time the site goes down. Whether or not this is true, it is a perception.

There's also probably more web dev jobs out there. You probably need only a small amount of infra people at any one time, but are developing a lot of features, some of which are low priority and can be outsourced.

> i realisticallly have time to only learn one at the moment

Then webdev. No-one wants someone they barely know or trust and just learned about AWS to manage their infrastructure

I would say webdev is more common anyway and can fit remote profiles. A good web developer can work out of anywhere and can have a separate Git repo/branch to work on. I would not be comfortable hiring someone for AWS/Infrastructure unless I can trust them a bit more.

Judging by recent hiring threads, webdev (React specifically) seems incredibly popular.
