Microservice Architecture Blueprint [on hold]

I am working on a microservice and I need some help to decide which layers my microservice should have. I come from the web applications worlds in which we had the following layers:

1.- Going from the client to the Database:

Controller > Facade > Services > DAO

2.- Going from the Database to the client:

DAO > Services > Facade > Controller

The question is, when creating a microservice there are obviously some layers that might not be necessary. What are the main layers that you would add to your microservice?
