Observability Patterns in a Micro Service Architecture

Part of what a service does is implement his is the business logic, right? I mean that's like the whole reason for it existing. But then in order to be sort of deplorable in areal application, thes a whole bunch of other stuff that you have to deal with. For instance, security. O that's obviously one really critical thing, right? Is services need to be secure. So that's one part of being production y that's separate from the business logic. And then another big part, that part there is observability, in a sense. Well, you always have to dealing with sort of observability or monitor ability, evenside a monolith.
