You

You • Most or all of you are Rails Developers, Agile Developers, Craftsman Developers, and run a rails shop

• Most or all of you have current deployments • On hardware not owned by your company • ...managed by someone else like Engine Yard? • On EC2? On other ‘Clouds’?

What were you doing before? • • • • •

Java Developer C/C++ Developer PHP Developer COBOL Developer Nothing: Rails/Ruby is my first development platform

• Goat Farmer? Stock Broker? Shoe Salesman?

Pivotal Labs • We make Pivotal Tracker • We’ve been doing agile for 10 years, first in SmallTalk, then in Java, now Rails and JavaScript

• We’ve grown from 20 to 70 since starting the Rails Practice 4 years ago

• We do enablement, but mostly implementation

Why do we build software • Because it’s cool • Because it’s fun • Because it’s exciting • Because we love the challenge • Because it beats the crap out of coal mining • Because employment is a nice thing to have

Why do Companies build software

• To make money • To save money • To manage risk • To satisfy business and government requirements

Building Business Value The revolution in Software is about one thing: Building business value as cheaply and efficiently as possible

So what’s expensive about software • Developers • Defects • Deployment/Operations • Code Maintenance • Change

Three Trends • Agile • Rails • The Cloud

What is it?

What’s in it for Us

What’s in it for Them

Agile

Cleaner, more flexible code; more fun coding; code is more maintainable

Fewer defects, more predictable delivery, more transparency, business determines what’s built

Rails

Cloud

More powerful, more Less effort = lower cost expressive, less grunt Less effort = shorter work, more gets done time to market with less effort, more Less effort = lower TCO fun. Lower TCO, No initial Easy Scaling, capacity investment, lower planning, setup, no operating costs, shorter pagers deployment cycle, no sunk cost

It’s the Economy, Stupid

• Budgets are smaller • The stakes are higher • Departments have to do more with less money • Failure, though always an option, is more catastrophic

So what’s this Agile stuff?

Manifesto for Agile Software Development We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
