microservices enable iteration agile programming unit testing & TDD scrum continuous integration … modern computer science values quantity, velocity over quality if you wait for all the data to make an informed decision, it may be too late to make any decision at all

OODA requires continuous delivery Adrian Cockcroft, former SVP of Web Engineering @ Netflix if you say “I’m doing this because it’s more efficient,” the unintended result is that you’re slowing someone else down. This is not an encouragement to be wasteful, but you should optimize for speed first. Efficiency becomes secondary as you satisfy the constraint that you’re not slowing things down. The way you grow the business to be more efficient is to go faster. “ ”

OODA requires continuous delivery http://www.slideshare.net/jallspaw/10-deploys-per-day-dev-and-ops-cooperation-at-ﬂickr John Allspaw - Flickr (not Etsy) We may deploy 20 times a day, but we wouldn’t deploy 20 times a day if we went down 20 times a day. The only reason we got to 20 times a day, is that the ﬁrst time we deployed 5 times a day, it worked out.” “ ”

spring boot it’s going to take an API.. lots of them! supports rapid development of production-ready applications and services

microservices introduce complexity • service registration & discovery?  (and client-side load balancing) • joined up views of data? • centralized conﬁguration management? • distributed tracing? • stream processing? • single sign-on

distributed systems are hard
