Has anyone used any tool to make infrastructure diagram cleanly. As we are adding more and more Miroservices it's kind of getting messy to look at these infra diagrams

I usually use excalidraw.com for these.

From my experience make this diagram update to the reality is quite complex, I prefer to have service maps using tracing info.

Try using draw.io or app.eraser.io

you may want to take a look at this - https://c4model.com/

If you're on a Mac and like plaintext(versioned diagrams is great), I'd highly recommend Monodraw.

You also have: https://mermaid.live/

I use LucidScale to reverse engineer my cloud infrastructure. If you’ve a lot of resources it can be to much information but filters help to simplify and get the view you want; especially if you’ve a good tagging strategy.

Lucidscale for enterprise wide solution or draw.io a free source

I really liked excalidraw for now but I am interested with what @Nicolas Takashi suggested. Any particular suggestions that I can try?

If you have distributed tracing you can use OpenTelemetry Collector and span https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/connector/spanmetricsconnector/README.md using Grafana for example you can use a node Graph Panel to build this live graph
