Infrastructure Automation COE, HP

You’re waiting for a train. A train that will take you far away. You know where you hope this train will take you, but you don’t know for sure. But it doesn’t matter, because we’ll be together.

This is the story of our journey to Continuous Delivery

HP is huge

Let’s zoom in to…

Just our lab

About 220 engineers working on about a

dozen projects

A year ago

What we did about it

ChatOps

GitHub Enterprise

Continuous Delivery

Infrastructure as

code

How We Built It Out

Strategy

• Find champions within organization• Small de-risking experiments• Roll out change incrementally• Continually demonstrate value• Listen to teams• Pick appropriate battles

GitHub Pull Request Builder

Plug-in

1. Let’s Collaborate!

2. Jenkins: Not just for PRs anymore

Sinatra App

Centralized logic of what to call when we receive an event

GitHub API

2. Jenkins: Not just for PRs anymore

Chef Server

System

sudo chef-client

3. Deployments API

Chef Server

What’s Awesome: Automation stays out of developers’ way

Projects can pick-and-choose what to adopt

What a Chef recipe pull request looks like to a developer

What a Deployment looks like to a developer

Started with low-risk, low-visibility projects

Demonstrated value: • Iterate faster with better visibility• Better team collaboration with less time wasted• Able to fix problems faster • Systems and deployments are consistent

Now using these methods to develop HP Support Automation 2.0 – Large, high-visibility project

Pattern used for a bunch of different projects

Add system provisioning to pipeline

Move more teams on boardImproving existing automation

Still more to do internally in my lab

Our lab now

Exciting times in my lab, but zooming out…

Challenges in the neighborhood: Isolated GitHub Enterprise instance

Exciting times at HP: Continuous Delivery Pilot

New policies emphasize enabling dev teams using whatever delivery pipeline works for them. Focus on API for shared

reporting/compliance.

The situation before my lab’s transformation isn’t atypical of large customers. A lot of large companies are facing the same need to migrate to a culture of continuous delivery

New HP Datacenter Infrastructure Automation COE team formed to help HP Datacenter Care customers through their own Continuous Delivery journeys

Jared and Andy are just some of the team members “on the ground” helping HP customers deliver value faster all day, every day.

Exciting time to be an HP customer
