Thank you for helping me understand what serverless means in practice. After I posted my comment, I was thinking that perhaps the main advantage of serverless is that it's not self-hosted. That's the "-less" part, I guess. > Running it yourself will not necessarily add any additional benefit and you will will have wasted time and effort getting this entire set of complex infrastructure setup before you have developed any application code to actually solve business problems. I see.. The use cases I'm thinking of are small to midsize companies, as well as tiny startups, so their needs are not that complex. I'm also interested in local development environment for serverless, so that's why I was curious about open-source, self-hosted services that are compatible or feature-similar to a limited subset of AWS.
