Josh Long - @starbuxman ! processing can’t scale up • concurrent, horizontal architectures are easier to scale • “process”-style concurrency is easy to scale still Moore’s Law is Broken Moore's law is the observation that, over the history of computing hardware, the number of transistors in a dense integrated circuit doubles approximately every two years. The law is named after Gordon E. Moore, co-founder of the Intel Corporation, who described the trend in his 1965 paper. http://en.wikipedia.org/wiki/Moore's_law

Josh Long - @starbuxman the Internet of Things ! IPv6 gives us more addresses ! devices are getting smaller, more ubiquitous ! “devices” include homes appliances (refrigerators, washers, coffee machines, dryers), roads, air pollution monitors, (human) body monitors, etc “In ﬁve years, by 2018, Earth will be home to 7.6 billion people, says the United Nations. By contrast, some 25 billion devices will be connected by 2015, and 50 billion by 2020, says Cisco.” http://www.businessinsider.com/what-you-need-to-know-about-the- internet-of-things-2013-3?op=1#ixzz3FxCafwWe

Slide 16

Slide 16 text

Josh Long - @starbuxman ! all services communicate via APIs (not backend databases!) ! APIs should be consistent ! HATEOAS promotes discoverability ! should be easy to stand up ! APIs should provide uniform monitoring and system endpoints for ease of integration into production APIs how do we

Josh Long - @starbuxman ! each service should be deployable without blocking other teams ! promotes agility in iteration ! polyglot services ! avoids “DLL hell” by isolating dependencies to the service Independent Deployability

Josh Long - @starbuxman ! Google built a custom stack based on C++, Java, Go ! TaoBao built frameworks on Spring (open sourced, too! “Dabbo") ! custom RPC, service registration, coordination ! http://bit.ly/1xt6hIE “Spring at China Scale” ! Baidu have frameworks also built on top of Spring ! Netflix have a large stack based on Spring and Spring Boot ! Twitter built a custom stack based on Scala ! Facebook built a custom stack based on PHP/“Hack” Others have walked this path

why PaaS? @Starbuxman https://github.com/joshlong/qcon2015-sao-paolo-microservices-workshop Imagine if architects had to be the janitor for every building they designed.

Josh Long - @starbuxman ! scale is everybody’s problem now, not just Netflix/Twitter/Baidu/Alibaba, etc ! “cloud native” is the new norm. It doesn’t have to be hard. ! Spring Boot simplifies application & service development ! Spring Cloud simplifies service interactions ! Cloud Foundry lets you deploy all the things, consistently; removes operational friction ! “smaller is more” Takeaways
