DevOps – The Missing Piece by Eficode's Marko Klemetti. Originally presented at 600Minutes Executive IT 2014 in Helsinki, Finland.

1. DEVOPS
THE MISSING PIECE

3. THE WATERFALL

4. AGILE METHODS

6. • Delivering features is often delayed
• Pieces don’t fit together
• Functionalities are not fully tested
before delivering
• New features break existing features
PROBLEMS IN AGILE

7. HOW DOES DEVOPS HELP?

8. #1 WELL DEFINED REQUIREMENTS

9. • All requirements and
documentation in one place
• Ability to follow features through
the development to delivery
• Connecting requirements to the
Quality Assurance

10. #2 INTERFACES

11. • The amount of mobile users and
the range of devices is growing at
a tremendous pace
• Vision: All content is available
through public interfaces

12. #3 AUTOMATIC QUALITY ASSURANCE

13. Transferring money using a phone number
Login to the payment service ${id}
Input recipients phone number ${number}
Input the payment amount €50
Accept the payment
Confirm the payment has been made
ROBOT FRAMEWORK

14. • Automatic acceptance testing of the
customer services
• Automatically verifying the range of
supported browsers and mobile devices
• Automatic regression testing

15. #4 CONTINUOUS DELIVERY

16. •• The amount of versions and
supported mobile devices is so
great that without fully automated
delivery chain the development
and support would be virtually
impossible

17. WHAT DOES DEVOPS BRING
COMPARED TO AGILE?
• Well defined requirements
• Interfaces
• Automatic Quality Assurance
• Continuous Delivery

18. AUTOMATIC SERVICE DELIVERY
AND VIRTUALIZATION

20. • Configuration Management
• Virtualization
• Scaling
• Monitoring
WHAT DOES DEVOPS BRING TO
SERVICE OPERATIONS?

21. • Continues from where the
Agile Development ends
• Aims to creating modular,
scaling and automatic service
maintenance
• Supports the organization by
focusing the work correctly
