4 Agenda Devops Intro Adoption Challenges What to expect when yo re adopting

5 DevOps is Different Things, bt in Common: An overloaded term (like clod ) What Modern IT looks like The coded bsiness policies The most advanced form of software engineering at scale Velocity is the end game, DevOps is the operating manal

6 Or highest priority is to satisfy the cstomer throgh early and continos delivery of valable software CORE VALUE OF DEVOPS

7 DEVOPS FLOW (VALUE STREAM) OPS DEV Transformation of good ideas into valable, working software rnning in prodction

12 DEVOPS IS Applied Agile, Lean, and Continos Delivery DELIVERY PIPELINE AUTOMATION Infrastrctre Tools Configration Tools Development Tools Test Tools Deployment Tools COLLABORATION Infrastrctre Development Qality Assrance Operations Secrity/Compliance

13 The Continos Delivery Game Rles Principles The process for releasing/deploying software MUST be repeatable and reliable Atomate Everything down to bare metal If it s difficlt or painfl, do it more often Keep EVERYTHING in sorce control Done means released Bild qality in Everyone has responsibility for the release process Improve Continosly

14 The Continos Delivery Game Rles Practices Bild binaries only once Use precisely the same mechanism to deploy to every environment Smoke test yor deployment If anything fails, stop the line

28 What to expect

29 Things to prepare for People Cltre Architectre Process Practices Tools

30 Roles Dev PMO Compliance Secrity Network Management IT Infrastrctre & Firewall

31 People Connecting with people across the organization People skills will become a core skill Testers coach devs on testable design

32 Cltre Everyone is a developer Everyone is a tester Everything is testing Adapt or wither away

33 Architectre Clod Containers Micro services

34 Infrastrctre Levels Application Consmable by DevOps Pipelines Sorce code, Schema Application COTS (Package) OR ALM Artifacts Internal Dependencies (libraries, frameworks versions, packages) Middleware Rntime Container OS OS VM Secrity Configration(s) External Dependencies (DBs, tiers, SOA, RPC) Configration(s) OS Configration(s) Manage Infrastrctre Services Configration(s) Network Storage Compte

35 Process DevOps Metrics Testing scope increases to other areas (secrity, compliance..) Featres and tests are developed incrementally (small batches) Tests planned and written at the same time as featres Exploratory testing rns in parallel Featre Flags for nreleased featres

36 Practices Inconclsive tests are nprodctive Tests are in the same sorce control branch as dev Allowance for easier A/B testing Testing the tests is essential Prodction monitor and alerts

37 Pets vs cattle Ephemeral environments become normal Tools Configration tools (Chef, pppet..) Toolset selection is pipeline-centered (no API? No thanks)
