Agile, ITIL, Cloud – Mit DevOps in die Zukunft

  1. 1. Agile, ITITL, Cloud How DevOps brings it all together Robert Michel +49 (0)170 6347249 michel@de.ibm.com
  2. 2. © 2013 IBM Corporation2 Agenda • DevOps – Challenges – Principles – Solution • Q&A
  3. 3. Collaborative Development & Operations Delivery challenges &Typical root causes
  4. 4. © 2013 IBM Corporation4 Why do we need DevOps? – 2 Examples Customer 1 Customer 2 Situation • Complex J2E environment • Many interdependent components • New release every 1-2 months Challenges • Change window on weekend too short • Each production deployment fails and takes 1 week to get it running • Different deployment approaches: • Test: fresh install • Production: upgrade install Situation • 5+ test environments with • Different OS versions • Different platforms (Linux, AIX) • Different J2E versions Challenges • Time consuming defect determination • Performance test takes 2 months • No production relevant test results • Can’t test N-1
  5. 5. © 2013 IBM Corporation5 Typical question within complex IT-Organisations • We are using agile development practices. Why does it still take months to release new applications? • Why is there so much rework to do for every new release? • Virtualization and Cloud are part of our infrastructure. Why does it still take so much time to provide a proper test environment? • Why do we still have significant quality issues despite our testing guidelines and processes?
  6. 6. © 2013 IBM Corporation6 Code BuildRequirements Reasons for issues Design Deploy Test Change & Configuration Management Deploy Test Deploy Test Deploy Test System Test Integration Test Acceptance Test Component Test Production • Staging and Testing require time and resources • Approx. 1/3 to 2/3 of time is spent for setup and configuration • Often different processes are used • No consistent Configuration Management throughout different environments • Knowledge kept within few individuals
  7. 7. Collaborative Development & Operations Agile development and DevOps DevOps principles
  8. 8. © 2013 IBM Corporation8 People Process Information DevOps Principles & Values • Collaborate across disciplines • Develop and test against a production- like system • Deploy frequently using repeatable and reliable processes • Continuously validate operational quality characteristics
  9. 9. © 2013 IBM Corporation9 Continuous Feedback  “Shift-Left” – shifting operational concerns and processes earlier in the development lifecycle  Collaborate on the creation of reusable test environment patterns  Common tools for planning, tracking, and reporting application and infrastructure changes IMPACT Predictable and accelerated software delivery optimized around a production-like delivery pipe Takes minutes / hours to deliver changes versus weeks/months Agile Dev Design Prioritize Build Test Agile OpsTest Monitor Publish Deploy Collaboration between Development & Operation
  10. 10. © 2013 IBM Corporation10 Delivery Pipeline Code Build Requirement Management DevOps Focus – Delivery Pipeline Design Deploy Test Change & Configuration Management • Complete Automation based on results of the previous steps • Sourcecode • „Infrastructure as Code“ • Patterns • Platform Configuration • Build Definitions • PackagingDeployment Patterns Configuration Automation Delivery Pipeline
  11. 11. Collaborative Development & Operations Concepts and Solutions
  12. 12. © 2013 IBM Corporation12 Build Automation Deployment Automation Test Automation Standardized, repeatable and automated „Delivery Pipeline“ Release Automation Continuous Integration of source code Integrated Deployment Model Continuous Testing Application ConfigurationEnvironment Cloud = continuous provisioning and deprovisioning of test stages dependent on application versions to test. Artefact Repository DevOps – Capability View
  13. 13. © 2013 IBM Corporation13 DevOps – What do I need a Cloud for? Layer Change Frequency Application Config Application Middleware Config Middleware OS Config OS Hardware Cloud Benefits • Deploy often • Control everything • Recreate n-1 easily • Provide standardized deployment patterns Cloud Automation Deployment Automation
  14. 14. © 2013 IBM Corporation14 ITILAgile DevOps – Process View OperateDevelop Test OperateDevelop Test Agile ITIL • Separation of duty in silos • No end-2-end visibility • Limited information exchange & process interfaces • Extend scope of agile principles and ITIL processes • Linked data vs. Integrated data & processes • Limited process changes necessary • Restructured Roles & Responsibilities (How do ITIL and Agile fit together?)
  15. 15. © 2013 IBM Corporation15 Benefits – Faster implementation of business requirements • Shorter test cycles • Keep up with the dynamic of agile development – Higher software quality – Cleaner transition from development to production • repeatable • automated • auditable
  16. 16. Thank you!
