3. IT transformation
Lean, Devops & Lead Time: facing the brutal facts

5. There is a perfect storm forming in IT industry
● programmable infrastructure: cloud, configuration
management, tooling and containers
● development of adaptable application: microservices,
distributed message/log processing, and event-driven
apps
● emergence of new processes/methodologies: Lean and
DevOps
CONTAINER ORCHESTRATION AND SCHEDULING: HERDING COMPUTATIONAL CATTLE

7. Adoption cycles, Simon Wardley
“The technology adoption
route for IT departments:
Ignore, prevent, tolerate,
allow, integrate.”
Joe Drumgoole, MongoDB

9. It’s all about
● fail fast, fail often
● measure actions and features precisely
● react properly, with feature rollout and kill switch
PaaS, Microservices, SMAC and Digital helps your company to react quickly

10. Continuous Delivery
Just-in-time deployability, where
deployment is not continuously possible

11. DevOps and Agile
Big-bang, turning-key deployment
● Redundant silos
● Wait time
● Provisioning Time
● Inconsistent envs
● Manual testing
● Heroes
● Long approval processes

19. To Avoid
● Devops != One-Click deploy
● Devops != Set of automation tools
● Automate everything from scratch
● Create a silo of initiative
● Sftw: Long-lived feature branches
● Sftw: Branch per environment

20. Achieving
● Have a plan. It’ about changing culture and process.
● Increment the process. Accomplish maturity
● Be realistic about your systems
● Document the process, evolve people

21. Achieving
● Microservices: for small deployments and testability
● PaaS: for smart infrastrucuture provisioning
● Log Harvesting: for measurement
● Comprehensive automated test to give confidence
● Hide unfinished features with feature toggles
● Small, incremental changes over big bang changes

22. DevOps: Five Key Challenges and Five Tips
DevOps adoption, challenges, & tools..
Common Obstacles
● Organizational complexity (people and depts)
● Roles, responsabilities and complex silos across devs & ops
● Product, service and development lifecycle complexity
● Complex downstream systems
● Lack of understanding by business teams
● Failed changes and systems outages
● Security, Audit and compliance

23. At the end of the day, DevOps only
matters if the business needs are met.
