Early microservice adopters seek speed and safety at scale. There are three levels of microservice architectures: modularized, cohesive, and systematized. Each level brings different benefits, enabled by microservice capabilities. Modularized establishes independence and testability, cohesive focuses on composability and efficiency through alignment, and systematized emphasizes agility, availability, and scalability through system design.

Business Value Stories
“We can scale our operation independently, maintain unparalleled system availability, and
introduce new services quickly without the need for massive reconfiguration.”
•Werner Vogels, Amazon (2006) https://queue.acm.org/detail.cfm?id=1142065
“…the next generation [architecture] that we are building will give Netflix a strong foundation to
meet the needs of our massive and growing scale, enabling us to delight our global audience.”
•Netflix (2015) http://techblog.netflix.com/2015/01/netflixs-viewing-data-how-we-know-where.html
“Lessens dependencies between teams - resulting in faster code to production.”
•Adrian Trenaman, Gilt (2015) http://www.infoq.com/news/2015/04/scaling-microservices-gilt
“With the new architecture framework, we were able to reduce our lead time for new features to
something that…was much more acceptable for a company trying to play in the highly competitive
music industry.”
•Phil Calçado, SoundCloud (2015) http://philcalcado.com/2015/09/08/how_we_ended_up_with_microservices.html

In summary…
Early microservice adopters seek speed and safety at scale
Three levels of microservice architectures:
• Modularized
• Cohesive
• Systematized
Each level brings different benefits
Microservice capabilities enable the benefits
