I am trying to host a simple Node.js app connected to MongoDB, I look on the web, I've found 2 different methods and some guides to do so: Different pods: Example from the official Kubernetes documentation. Example from the official Google Cloud Platform documentation. Same pod: Example from the official IBM documentation. This confused me a bit, which is the best practise to achieve that?

Should Node.js and MongoDB be in different pods?
