There are a few tools for distributed tracing in the cloud, e.g. XRay (https://aws.amazon.com/xray/) from aws itself or open-source projects like Jaeger (https://www.jaegertracing.io/) and Zipkin (https://zipkin.io/ ).

Do you have experiences with any service in this category? Are they worth it or should I avoid the complexity as long as possible? Or should I go with service meshes since they have tools to do distributed tracing in place, but may increase the complexity even more, like AWS App Mesh, Istio (https://istio.io/latest/), Consul (https://www.consul.io/) or Linkerd (https://linkerd.io/).
