What is the term describing this architecture?

Let's say I have a web application where each page or even part of a page are rendered on a different rendering fleet. The application is also fronted by multiple layers of load balancers and a reverse proxy. The data storage is clearly decoupled from the rest of the app. Another aspect is that the app uses web services for inter-component communication.

Now, the application is definitely distributed, it is also multi-tiered and service-based. But my question is: is there a term encompassing all these characteristics? I'm looking for a single term (like multi-tiered or distributed) to describe this kind of web architecture.
