As someone who has some experience in observability at scale, the issue with SigNoz, Prom, etc is that they can only operate on the data that is exposed by the underlying infrastructure where the IaaS has all the information to provide a better experience. Hence CloudWatch.
That said, if you own your infrastructure, I’d build out a signoz cluster in a heartbeat. Otel is awesome but once you set down a path for your org, it’s going to be extremely painful to switch. Choose otel if you’re a hybrid cloud or you have on premises stuff. If you’re on AWS, CloudWatch is a better option simply because they have the data. Dead simple tracing.
