First-time founder looking for some advice on the lowest friction way to set up CI. In the past I used Jenkins and a combination of Teamcity and Github actions, is there a consensus on what's the simplest/most boring technology to use for this? The rest of the techstack is a monorepo of django and a couple of (typescript) next.js apps, a variety of AWS services and I want to avoid pushing the boat out on  stuff that isn't a value add but also want to make sure there isn't some great alternative that I'm not aware of.At the moment CD is just me running "eb deploy" every so often which isn't great.
