PaaS Enables DevOps
Automation delivers high quality software, faster than ever
AUTOMATION
Let’s integrate tools and automate
processes from testing, to builds and
deployment
SPEED
Releasing smaller things more often
will reduce complexity and improve
time-to-market
QUALITY
Reducing the feedback loop using
test-driven development will surface
problems sooner, while helping us be
more responsive to change
AGILITY
Let’s push updates on a regular
basis without ANY downtime to
improve customer experience and
shorten time-to-market
Automated Build + Quality
