   ! 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.

    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.”

    A Mental Model for Scale
    Chris Richardson (@crichardson) 

    (http://microservices.io/articles/scalecube.html) introduced me
    to this “scale cube” from The Art of Scaling Software

    ! 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

17. 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

    code will be open sourced.

    ! 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

    ! embrace DevOps
    ! don’t throw code over the wall
    ! map your team to your business vertical
    ! Netflix have teams and then the platform group who provide infrastructure
    for teams.
    Integrated Teams, not Silos

    Imagine if architects had to be the
    janitor for every building they designed.
    This is how the development team felt
    prior to moving to Windows Azure.

    ! 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”
