DevOps At Scale’’What we did, what we learned at Societe Generale’’
A Continuous Delivery program
@adrienblind
A transformation program
Objectives
QualityTime-To-MarketValue
▪ Get inspired from web giants
▪ Focus on the operational aspects
▪ Practices > Tools
Approach
▪ A pre-existing ”agile center”
▪ Agility brings value only if iterations deliver the product
▪ Transform an existing landscape
Context
@adrienblind
Triptych of complementary set of practices
Agile
“Implicate all stakeholders on the product, deliver
more rapidely and smoothly value for the business”
Craftsmanship
“Build robust and sustainable code”
DevOps
“Devs & Ops collaborate to build and operate
the product, they particularly leverage on
strong automation & metrology”

Increase impacts…
LEARN FROM YOUR PRODUCT
FOSTER COLLABORATIONRELEASE FREQUENTLY
LOWER STRESS AND RISK
SHIP confidently & faster the product
Product-centric
Software oriented
Change oriented
Deliver rapidely new
features with quality
Application teams (DEVs)
fosters INNOVATION
Stability oriented
Ensure proper run of
applications
Operation teams (OPs)
fosters RATIONALIZATION
Service-centric
Server, storage,
databases
Committed together toward the whole product’s lifecycle“You build it, you run it”
Different objectives
leading to
confusion & friction

e.g. INFRA is becoming SOFTWARE
(Infrastructure as Code)

@adrienblind
Operational aspects – target
Feature teams made of BA/Devs/Ops people, agile & collectively engaged on the
whole lifecycle of their product
The best friend of an Ops is the Dev who built the feature he
deploys and operates
