Small Batches

The “Lean Startup” Approach, Hypothesis Driven Development, aka, “The Scientific Method

• Deploy to production each time, avoid waterscrumfall

• Relies on:- Product approach- Small batch oriented

pipeline and process- Cloud native automation

Inception

Validate w/real use(r)s

Did it work?

Deploy to Prod

• Developer crafted (before impl.)• Stubs/mocks external services• Developer executed (before commit)• CI executed (after commit)

(after commit)• Developer or QA crafted• CI executed• Runtime context (buildpack applied)• Binds to test services (DB, messaging, etc.)

• “cf push”• Runtime context (buildpack applied)• Binds to test services (DB, messaging, etc.)• Periodic smoke tests

• “cf push”• Runtime context (buildpack applied)• Binds to prod services (DB,

Exploration Discovery

Go big with small batches

• Vitality drove engagement from 3% to 30%+

• Cue Apple Watch app: “Two people built the app and got it into the AppStore in five weeks.”

Source: Humana keynote, CF Summit 2015. "Application Modernization, Service By Microservice," Forrester, Dec 2015. See also BMC Software case study in The Concise Executive Guide to Agile and Cutter Executive Report, Vol. 9, No. 9, 2008.

"We did an analysis of hundreds of projects over a multi-year period. The ones that delivered in less than a quarter succeeded about 80% of the time, while the ones that lasted more than a year failed at about the same rate. We're simply not very good at large efforts.”

You’ll Need a Platform

Continuous DeliveryRelease once every 6 months

More Bugs in production

Release early and oftenHigher Quality of Code

DevOpsNot my problem

Separate tools, varied incentives, opaque process

Shared responsibilityCommon incentives, tools, process and

culture

MicroservicesTightly coupled components

Slow deployment cycles waiting on integrated tests teams

Loosely coupled componentsAutomated deploy without waiting on

individual components
