Traditional infrastructure in the Cloud. Lipstick on a pig? David O’Brien Senior DevOps Consultant Versent

DAVID O’BRIEN MVP for Microsoft Azure Senior DevOps Consultant @ Versent Cloud // Automation Founder of Melbourne PowerShell meetup German – Scottish From Melbourne / Australia @david_obrien https://david-obrien.net https://versent.com.au

Agenda Let’s set some ground rules for “cloud” Lift & Shift Transformation Stories from the Trenches

Some ground rules for “cloud” If possible avoid IaaS It’s hard to manage and maintain Unless you sell VMs, it won’t give you any actual benefits Except, you can now continue running your old apps – congrats! Be as high up the stack as possible If unavoidable… Try not to get attached to your servers (no pets) Automate Don’t do things the way you always did them unless you did them great! Save money! Know where your stuff is and what it is doing!

Why lift & shift???

Reasons to move Hardware lifecycle Datacentre exit Strategic decision Acquisition (active or passive)

3 years Cost Breakdown Environment Details

Transformation (Cloud Mode 2) Automate the app installation Bake images Add your app to a custom image Focus on Feature, MVP & Iterate Maintain Discipline Early Look Performance What am I logging & monitoring Test Driven Development Artefacts & Automation Build to fail Take risks! Build to scale

DevOps all the things - Is not a thing! Make intelligent decisions about your environment.

- Not a thing!

Stories from the trenches Strategic decision to move first, transform when moved Vendor engaged to analyse app ecosystem Identify quick wins for transformation Lift & Shift was highly automated Certain apps retired or decommissioned Higher cost of cloud accepted for Mode 0 Cloud seen as another datacentre Lift & shift without changing mindset Processes weren’t adapted No native services leveraged Outage -> cloud was blamed! “But that’s why we moved to $cloud” “Everything fails all the time.” - Werner Vogels (CTO of AWS) Bill shock!

So accept that and stare into it. THIS SH**’S NOT EASY! Going from traditional to contemporary is about as far from easy and commodity as you can get. So accept that and stare into it.
