How long does it take you to deploy your application?
INCLUDING ROLE BASED ACCESS
INCLUDING MONITORING
INCLUDING CONNECTIVITY
DEVS VS. OPS
• “Move fast and break things.”
• Iterations: from 2 weeks down to continuous
• “It works on my machine!”
• Security? Privacy? Backups?
• “Don’t fix it if it ain’t broke.
• Procurement: from 2 weeks up to 4 months
• Dev ≠ Test ≠ Staging ≠ Production
• Security! Privacy! Backups!
WHAT DEVOPS IS NOT
• Tool or Technology
• Methodology
• Role or a Team
• Silver bullet

INFRASTRUCTURE AS CODE
• Can be checked into source control
• Can be versioned
• Can be audited
• Can be automatically executed
HOW WE USED TO DO SOURCE CONTROL:
“Don’t touch files A and B I’m not done with them yet.”
GITPlus branching strategy (e.g. git flow)

WE CAN REWRITE OUR SERVICES AT WILL - WHICH WE DO, RATHER THAN CONTINUE TO REFACTOR THEM OR TO ADD MORE AND MORE TECHNICAL DATA OVER TIME. WE JUST REWRITE THEM WHEN WE GET TO A SCALING INFLECTION POINT.

WHAT DOCKER IS NOT
• Not just lightweight VMs
• Not another configuration management tool
• Not a silver bullet
APPLICATION WITH DEPENDENCIES

“The biggest single benefit of Docker is the extent that it’s empowered the team to build services from scratch. We no longer have a complex set of provisioning scripts or AMIs—we just hand the production cluster an image, and it runs. There’s no more stateful instances, and we’re guaranteed to run the same exact code on both staging and prod.”

• Can run on-premise
• Bare metal
• OpenStack
• Kubernetes Federated Clusters!
• Hybrid cloud

CD SECOND ORDER EFFECTS
• Overall development costs reduced by ~40%
• Programs under development increased by ~140%
• Development costs per program reduced by 78%
• Resources driving innovation increased by 5x
CANARY RELASES
PUSHING IN MULTIPLE PHASES• latest - a version of the site running the latest code at all time. Employees
would use this site and find any major bugs almost instantly.
• p1 - a handful of servers that would be the first to run the new code in production. The goal of this was to catch any obvious fatals/warnings in the logs before a new release would gain wide distribution.
• p2 - a larger set of servers on the web tier. The number of servers in p2 increased over time, but I believe hovered around 5% or so. This offered several opportunities, including catching long tail fatals and monitoring resource use along with key user metrics on the servers for any anomalies.
• p3 - the entire web tier.
