Yep, there's a premium on making your architecture more cloudy. However, the best point for Use One Big Server is not necessarily running your big monolithic API server, but your database.
Use One Big Database.
Seriously. If you are a backend engineer, nothing is worse than breaking up your data into self contained service databases, where everything is passed over Rest/RPC. Your product asks will consistently want to combine these data sources (they don't know how your distributed databases look, and oftentimes they really do not care).
It is so much easier to do these joins efficiently in a single database than fanning out RPC calls to multiple different databases, not to mention dealing with inconsistencies, lack of atomicity, etc. etc. Spin up a specific reader of that database if there needs to be OLAP queries, or use a message bus. But keep your OLTP data within one database for as long as possible.
You can break apart a stateless microservice, but there are few things as stagnant in the world of software than data. It will keep you nimble for new product features. The boxes that they offer on cloud vendors today for managed databases are giant!
