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
