21. “Progressive
Delivery"

23. “Progressive Delivery is the next step after Continuous
Delivery, where new versions are deployed to a subset of
users and are evaluated in terms of correctness and
performance before rolling them to the totality of the
users and rolled back if not matching some key metrics.”
- Carlos Sanchez, CloudBees

31. We roll out a new service to 5% of our customers first.
What sort of users choose to use this feature? We roll out
the service then leverage our logs to understand the
behaviours of the system and users. Logs are integral to
understanding how new code is being shipped, how you do
A/B testing in production. We do testing in production.”
Bruno Kurtic, founding vp

34. Think about which users you’re rolling out a service to,
when, in which order and why.
Do Japanese customers use services differently?
Grubhub canary deploys to small cities first
SRE Book Golden signals – latency, errors, traffic, saturation

40. If statement
for features

41. Release Progression – progressively increasing the
number of users that are able to see (and are impacted
by) new features.
Delegation – progressively delegating the control of the
feature to the owner that is most closely responsible for
the outcome.

49. Service meshes give you
Advanced service routing and traffic shifting
Easier Rollbacks
Automatic metrics, logs and traces (Prometheus)
And so, Progressive Delivery

56. align User Experience and Developer Experience
enhanced A/B testing
experimentation and feature flags
manage deployment target complexity
reduce business risk
decouple deployment from service activation
Bring the business back into control of rollouts – towards product management focus
Turn pace of software delivery into a service management feature
Avoid rollbacks and emergency fixes across mass user populations
Debug in production, across a limited user population
Deploy!=Release
Think about which users you’re rolling out a service to, when, in which order, and why.
