![]() This offers nearly as good isolation and crucially is lightweight. Rather than running separate OSs, Docker isolates each app at the application layer - each app is in its own container and they are managed by a Docker daemon running on the same host OS. An entire VM seems very wasteful, especially if the application itself doesn’t require many resources. ![]() The issue with this is that each VM requires a sizeable chunk of resources (multiple GBs of RAM, multiple CPU cores etc). One approach you might consider is to run each application in a separate virtual machine so each application has its own resources and is isolated from the others - we say they are sandboxed. ![]() What is Docker?Ĭonsider trying to isolate different applications. Dockerĭocker is all the rage when it comes to developing scalable applications, so a very useful technology to be familiar with. Check the tutorial branch to see the code we are interested in (the master branch also contains the other sections of the project).įor sake of brevity the blog post will only highlight the important parts of the code, however I encourage you to fork the repository and build upon the tutorial repo when creating your own database and endpoint. ![]() This example repository contains code for a database server storing air pollution sensor data.
