This document discusses various topics related to software development including microservices, continuous delivery, cloud computing, and agility. It provides contact information for Josh Long who is an expert in these areas and promotes Spring, an open source development platform. It encourages embracing agile practices and tools like Spring Boot, Spring Cloud, and Pivotal Tracker to help deliver features quickly and remove the gap between development and production.

9. - the agile manifesto espouses
several key ideas that we take for
granted today:
* individuals & interactions first,
working code first, collaboration
first, and responsiveness first.

12. don’t reinvent the wheel

13. spring boot
- Spring Boot provides an impressively simple way to build software.
* red-green test the software
* satisfy the story and deliver the feature(s).
- but remember, were trying to get softare that is 'done'! 'done'
implies a lot of x-cutting concerns and a lot of non-functional
requirements.
* Boot's got you covered there, too. (look at /actuator etc etc)
- Deployment: executable jars, `system.d`, `init.d`, look at how easy it
is to deploy this to a modern environment like CF `cf push -p my-
app.jar my-app`
- MAKE JAR NOT WAR
- ive seen a lot of apps that combine their Apaceh Tomcat config in
the same bundle as their app itself. this implies that teh cofniguration
is app specific, so why shouldnt it live with the app itself?

14. microservices

15. a monolith might be the right answer

16. - the discussion is really about removing the delta
between delivery of software to customers.
microservices are a part of that larger goal.

to produce designs which are copies of the communication
structures of these organizations

19. - the things we do and things we build help people achieve this. it helps devs
win.
- sizing is important.
* Netflix famously talks about their 2 pizza box teams: mall enough to feed w/ 2
pizza boxes fo food
* of course, this # includes management, operations, ec. a truly cross-
functional team.
* rules of thumbs for teasing a microservice out: independently reusable,
bounded context, scale out when a piece of code is logically deve;oped by a
diff team.
- As the software becomes larger and the boundaries of the components have
been teased apart it becomes useful to tease things apart - to functionally
decompose them. there are several benefits that come from this, but the big
one is organizational agilty.
- or conway's law: software reflects the organization that it serves. period.
distributed systems are hard

20. spring cloud
Apache Zookeeper
these logos are all trademark/copyright their respective owners (T-B, L-R):
Netflix, amazon.com, Apache Software Foundation, Cloud Foundry, Hashicorp
they are ALL great organizations and we love their open-source and their APIs!!
