That’s right but kubernetes and helm make it easy to launch entire service stacks at a new version. That’s been my approach. Launch a new application and change DNS or ingress, etc. When satisfied, trash the old application.
I mean there's no reason you can't do that, I think that's a fine approach personally. I'm not really sure you gain much from focusing on developing tons of microservices at that point though. In general it's going to add complexity to your project, and at the end of the day you're still deploying it as one big single service so I'm not really sure you gain much from the added complexity. That said, I'm not really huge on microservices to being with, so I may not be the best one to talk to about them ;)
Definitely a good approach, I'd like to update the article to mention this as a recipe for success. The only challenge I've seen is when the old app is still doing work behind the scenes, such as running crons or dequeuing messages or whatever.
