Hi, I maintain the open source project OpenFaaS.<p>If you've not seen Ivan's content before and are interested in cloud and containers, I'd highly recommend having a read of his articles. Several have been on the front page of Hacker News and rightly so - he's got an accessible writing style and includes plenty of diagrams.<p>One way I use the project is for extending a SaaS like Gumroad - to add new tiers of discount or to alert myself via Slack. It could be useful for one of your side-hustles or for some integration that just gets out the way. Ivan covers how you can write functions with regular binaries or bash, or one of the templates from the open-source community.
