TRANSCRIPT
DevOps & Continuous Delivery
A software craftsman approach
IT transformationLean, Devops & Lead Time: facing the brutal
facts
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

Adoption cycles, Simon Wardley
“The technology adoption route for IT departments: Ignore,
prevent, tolerate, allow, integrate.”
Joe Drumgoole, MongoDB
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
Continuous DeliveryJust-in-time deployability, where deployment is not continuously
possible
DevOps and Agile
Big-bang, turning-key deployment
● Redundant silos● Wait time● Provisioning Time● Inconsistent envs● Manual testing● Heroes● Long approval processes

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