will be "build," not "buy.

Gartner predicts that by 2020,

75 percent of applications supporting digital business

Custom written software is becoming a key competitive advantage

Turn “failure” into “learning”

How most businesses think they’re

doingHow smart businesses

know they’re doing

First step: admit you have no idea what’s going on

Be successful* at a small series of projects* Don’t talk a lot about the failures

Strict testing to hold back calcifying technical debt

QA - automated testing to avoid technical debt, move fast

Uptime - testing for resiliency in production

Design quality - do people actually find your software useful?

Improvement - testing your process

14

Use 12 factor app principles to create cloud ready applications A set of best practices

for developing and deploying cloud-native software.

Practices translate into platform features and workflow requirements.

Architect with microservices in mind Decompose everything into

services Think of *nix style pipes on the

CLI, but in a distrusted system Each service is owned by a team

and indepdent A black-box with a well done API Benefits: scale, comprehensibility,
