At Paddy Power, we spent 18 months building out an enterprise Platform as a Service (PaaS) and Continuous Delivery (CD) capability. It’s been a challenging journey but one through which we've gained many valuable insights. We’ve created a very impressive capability that allows us to declaratively define application topologies using Cloudify and have that application delivered to production via a fully automated staged delivery pipeline. This presentation described this journey to the London continuous delivery user group.

1. Optimising For Speed

2. About
• Work for Paddy Power
• Predominately development
background
• Been leveraging CI since ~ 2003
• I haven’t written any books
• But…if I did, I would have
written…

3. • Because you want to win!
• By beating your competitors.
• By growing the market.
• By growing your market
share.
Why Optimise for Speed?

4. • Making decisions quickly.
• Building better, faster, lighter.
• Your organisation must exist to
support your engineering team.
• Replace human interaction
with API invocation.
How to Optimise for Speed

5. • Engineers own quality.
• You write it, your run it!
• Avoid moral hazard!
How to Optimise for Speed,
Safely

6. How to Optimise for Speed,
Safely
• Continuous Delivery vs Continuous Deployment
• Continuous Delivery requires manual promotion.
• Continuous Deployment is fully automated.
• Continuous Delivery is an opportunity to realise
efficiencies through convention.
• Continuous Delivery is realised through a staged
pipeline.

7. How to Optimise for Speed,
Safely
• Change the characteristics of the system complexity.
• Monolithic architectures centralise complexity.
• Distributed architectures distribute complexity.
• Manage distributed systems complexity with PaaS.
• Provide operational tooling through PaaS.

28. Configuration Management
• Control the functional and physical attributes of a
system.
• Desired state configuration allows you to declaratively
specify they system configuration.
• Convergence applies the desired state to the system.
• In distributed environments, Desired State
Configuration tooling requires orchestration.

33. –Kevin Kelly, co-founder of Wired Magazine
“The nature of an innovation is that it will arise at
a fringe where it can afford to become prevalent
enough to establish its usefulness without being
overwhelmed by the inertia of the orthodox
system.”

34. –Clay Shirky
“Institutions will try to preserve the problem to
which they are the solution.”
