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

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.
