ild once, deploy anywhere” is really nice on the paper but if you want to use ARM targets to reduce your bill, such as Raspberry Pis and AWS A1 instances, or even keep using your old i386 servers, deploying everywhere can become a tricky problem as you need to build your software for these platforms. To fix this problem, Docker introduced the principle of multi-arch builds and we’ll see how to use this and put it into production.

Awesome-Compose: Application samples for project development kickoff
Software systems have become quite complex nowadays. A system may consist of several distributed services, each one providing a specific functionality and being updated independently. Starting the development of a project of such complexity is sometimes time consuming, in particular when you are not already familiar with the software stack you are going to work on. This may be because, most of the time, we need to follow rigorous steps to put together the entire project and if we make a mistake in-between, we may have to start all over again.
