2. A Day in the Life... My job titles (alphabetically): • Member of fun committee • ScrumMaster • Software Engineer • System Engineer • Team Lead • (other duties as assigned) ◦ Customer support ◦ Documentation ◦ Jira ◦ Meetings ◦ Reporting And when I am not at work… • Bake cookies, cakes • Catch up with my kids (both my daughters are engineers) • Enjoy nature - walk every Saturday • Go to concerts • Try to read actual books • Volunteer (college, high school, middle school, women in tech) • Watch Hockey Games (Go Caps! Bruins!) 2 I love deadlines. I like the whooshing sound they make as they fly by. ~ Douglas Adams
3. So… why is DevOps so important to me? • Cooperation • Communication • Repeatability/Consistency • Efficiency 3 © 123RF
4. ...and why is Automation so Important in DevOps? My Personal DevOps Process • Perform Manually/Document • Script • Test/Peer Review • Release • Retrospect and start again Every step in this process brings improvement, so even if you do not get beyond the documentation step, you’re ahead... 4 © 123RF
5. A quote so I can ramble on a little more... “Life is trying things to see if they work.” – Ray Bradbury 5
6. Why automate? • Speed • Consistency • Cost-savings • Reduce human error • Scalability • As part of CI Process 6 © 123RF
7. What do we automate (some examples) • Repeatable Processes • Testing • Deployment Processes • Hardware/Software Status • Metrics/Reporting • Boring stuff (email sorting, etc) • For convenience (IFTTT) 7 © Thanks, Allie Brosh, “Hyperbole and a Half”
8. What tools do we use? • Ruby, Perl, Python, Java, etc • Jenkins, Travis, Gitlab-CI, etc • Puppet, Chef, Salt, Ansible • Database queries • Cron jobs • APIs • ...and many more 8 © 123RF
9. Why would you *not* automate (some reasons) • The time to automate is longer than time to perform the task and ...the task is not performed often • Interim results and statuses need to be available • Human intervention needed • Security risk (e.g. plain-text passwords) • Correct automation tools not available • Trying to automate too much at once • Creativity 9 © 123RF

11. Why do people fear automation • Fear of losing a job • Don’t trust what they can’t control • Lack of knowledge of tools 11 “Good afternoon, gentlemen. I am a HAL 9000 computer." – HAL 9000 - 2001: A Space Odyssey
12. The CLI (Command Line Interface) and the API (Application Program Interface) • Accessibility (screen-readers are happier with plain text) • Easy to read and recreate/repeat • Often too many options to fit on a readable GUI screen ...or too much output to view at once • Return data in a format for reuse (.csv, .json, etc) 12
13. CLIs • Easy to read and recreate (pkzip) • Can fit more into less space/time 13
14. APIs • “a set of functions and procedures allowing the creation of applications that access the features or data of an operating system, application, or other service.” – Wikipedia • Get data needed from a function call rather than navigating • Data is returned in a readable format • Data can be manipulated before presented to the end user 14
15. An API in action 15
16. Some Metrics that show what we’ve gained • Cost • Test coverage • Customer Satisfaction • Defects Found • MTTR (mean time to recover) • Time Saved on testing • Time to release • Risk 16 © 123RF
17. Toll house cookie slide • 2 1/4 cups all-purpose flour • 1 teaspoon baking soda • 1 teaspoon salt • 1 cup (2 sticks) butter, softened • 3/4 cup granulated sugar • 3/4 cup packed brown sugar • 1 teaspoon vanilla extract • 2 large eggs • 2 cups (12-oz. pkg.) NESTLÉ® TOLL HOUSE® Semi-Sweet Chocolate Morsels Bake at 375 degrees for 7-9 minutes 17
18. Resources • I totally started to write a list of resources here • But then I realized I was surrounded by amazing DevOps people • And many of them have read – and written – so much about automation, • So… Look around you! 18 © 123RF.com
19. Quotations “If you automate a process that has errors, all you’ve done is automate the generation of those errors.” – W.L.W. Borowiecki “Any daily work task that takes 5 minutes will cost over 20 hours a year, or over half of a work week. Even if it takes 20 hours to automate that daily 5 minute task, the automation will break even in a year.” – Anthony J. Stieber "I will always choose a lazy person for a difficult job. Because, he will find an easy way to do it." – Bill Gates “You can’t automate stupid!” – Kitt 19
