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

4. 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!

7. Why lift & shift???

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

10. 3 years Cost Breakdown
Environment Details

11. 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

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

14. - Not a thing!

15. 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!

16. 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.
