I don't know if there is a unified playbook, but there are random blog posts. One that comes to mind (disclosure: I worked on the system, mostly after the blog entry) is https://dropbox.tech/infrastructure/courier-dropbox-migration-to-grpc https://dropbox.tech/infrastructure/courier-dropbox-migratio... (and perhaps https://dropbox.tech/infrastructure/how-we-migrated-dropbox-from-nginx-to-envoy https://dropbox.tech/infrastructure/how-we-migrated-dropbox-...) I suppose the problem with an easy go-to playbook is if that were easy to pick one solution for every problem, gRPC would have likely picked it by default (I can attest the team, and the external contributors, are top notch, having worked alongside them). Unfortunately some problems, at scale, need to be answered depending on architecture with the holistic system in mind, and are not just gRPC issues. Truth is large scale systems are hard to build and operate. Perhaps that is why you get help from experienced individuals and consultants. I do agree some documentation/tooling is lacking and could be improved to guide folks through the process.
