Discussion on: 16GB or 32GB RAM for Web Development?

As previously stated by some people I would also go with "it depends" and right away on "Do you use virtualisation?". Reason is that when I want to build something in Java like simple monolithic service with some web interface, let's say you go ahead and generate JHipster app, you really don't need more than 16GB to run it including IntelliJ, VS Code for front, maybe a simple DB running inside Mongo or PostgreSQL. You can even have DB running in Docker with this kind of setup.

Now I have 48GB, it's funny but I had 16 and added 32 more. Thing is I'm running 1 REST API which is a bit bigger than standard microservice, 2 more APIs, and Mongo, Neo4j, and Apache in docker. Now imagine running 3 APIs written on JVM (Kotlin, Groovy, Java) 2 DBs and 1 messaging system, 3x IntelliJ for that, VS Code, Postman, couple of Notepads and Sublimes, Opera with couple of tabs and Brave also couple of tabs, Slack, sometimes tools like Azure Storage Explorer, MS Teams, node.js apps for administration of these tools running in docker... Yeah, even GNU/Linux would give up at some point and ask for more RAM because you still need GUI running, maybe Spotify, and such. Now you might go with less RAM for all of this but I like my IntelliJ and I like not closing stuff all the time.

ha, fair enough!

I don't use VMs that heavily now, but I possibly will more in the future. I think I will go with 32GB because of the longevity it'll add to the machine. Being non-upgradable I think 16GB will shorten its useful life.
