“YOU BUILD IT, YOU RUN IT” –Werner Vogels, Amazon @kmugrage https://queue.acm.org/detail.cfm?id=1142065
“GIVING DEVELOPERS OPERATIONAL RESPONSIBILITIES HAS GREATLY ENHANCED THE QUALITY OF THE SERVICES, BOTH FROM A CUSTOMER AND A TECHNOLOGY POINT OF VIEW. THE TRADITIONAL MODEL IS THAT YOU TAKE YOUR SOFTWARE TO THE WALL THAT SEPARATES DEVELOPMENT AND OPERATIONS, AND THROW IT OVER AND THEN FORGET ABOUT IT. NOT AT AMAZON. YOU BUILD IT, YOU RUN IT. THIS BRINGS DEVELOPERS INTO CONTACT WITH THE DAY-TO-DAY OPERATION OF THEIR SOFTWARE. IT ALSO BRINGS THEM INTO DAY-TO-DAY CONTACT WITH THE CUSTOMER. THIS CUSTOMER FEEDBACK LOOP IS ESSENTIAL FOR IMPROVING THE QUALITY OF THE SERVICE.” –Werner Vogels, Amazon @kmugrage https://queue.acm.org/detail.cfm?id=1142065
USE MODERN ARCHITECTURES AND TECHNOLOGIES
MONOLITHS CAN BE HARD ▸ All functionality is in one process ▸ Scale by replicating the monolith on multiple servers @kmugrage https://www.thoughtworks.com/insights/blog/microservices-nutshell
DEVELOP SMALLER PIECES MICROSERVICE ARCHITECTURE ▸ Each element of functionality is in a separate service ▸ Scale by distributing these services across servers, replicating as needed @kmugrage https://www.thoughtworks.com/insights/blog/microservices-nutshell

CONTINUOUS DELIVERY IS THE ABILITY TO GET CHANGES OF ALL TYPES—INCLUDING NEW FEATURES, CONFIGURATION CHANGES, BUG FIXES AND EXPERIMENTS—INTO PRODUCTION, OR INTO THE HANDS OF USERS, SAFELY AND QUICKLY IN A SUSTAINABLE WAY. Jez Humble @kmugrage https://continuousdelivery.com/
MORE HOMEWORK @kmugrage
CONTINUOUS DELIVERY IS WHAT YOU “DO” AS PART OF A DEVOPS CULTURE Me @kmugrage
A PREREQUISITE TO CD CONTINUOUS INTEGRATION
CI THEATRE The ThoughtWorks tech radar recently recommended putting a hold on the tech team anti-pattern, CI Theatre. CI Theatre describes the illusion of practicing continuous integration (CI) while not really practicing it. @kmugrage https://www.gocd.org/2017/05/16/its-not-CI-its-CI-theatre/
CI THEATRE In another ThoughtWorks study only 10% of participants acknowledged that having a CI server was not the same as practicing CI. @kmugrage https://www.gocd.org/2017/05/16/its-not-CI-its-CI-theatre/
ARE YOU PRACTICING CI? @kmugrage

Moving your organization to a DevOps culture isn’t as simple as buying a tool. It requires changes to many parts of your process. In this talk, you’ll get tools to understand terms in the DevOps space more clearly, team structures required for success, modern architectures, and the importance of a continuous delivery in the journey to “doing the DevOps.”
