Microservices v.s. Monolithic: Scalability

A monolithic application puts all itsfunctionality into a single process..

... and scales by replicating the monolith on multple servers.

A microservice achitecture puts each functionality into a separate service..

... and scales by distributing these servicesacross servers, replicating as needed.

Microservices v.s. Monolithic: Database

http://martinfowler.com/articles/microservices.html

A monolithic architecture uses the same database for all services.

A microservice achitecture uses the bestdatabase ..
