A quick introduction to the building blocks and high level concepts about DevOps as the path to Cloud Native applications.

• In 1999, built a 20M page view per month Web site
• On two (2) HP servers (active-passive, manual
failover)
• Dual Pentium 3 CPUs at 500+ MHz, 256MB RAM,
200GB HD

• “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!

21. WHAT DEVOPS IS NOT
• Tool orTechnology
• Methodology
• Role or aTeam
• Silver bullet

Infrastructure as Code

31. INFRASTRUCTURE AS CODE
• Can be checked into source control
• Can be versioned
• Can be audited
• Can be automatically executed

32. HOW WE USEDTO DO SOURCE CONTROL:
“Don’t touch files A and B I’m not done with them yet.”

33. GIT
Plus branching strategy (e.g. git flow)

• Not just lightweightVMs
• Not another configuration management tool
• Not a silver bullet

66. “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.”

68. KUBERNETES
• A platform for container management and
orchestration
• Started by Google (based on their internal
Borg platform) and released Open Source
• Donated to the Linux Foundation in 2015
• 4000+ contributors and 40,000+ code
commits (Dec 2016)
• Being adopted quickly by large Enterprises,
Banks, Retail, etc (Walmart, SAP, Goldman
Sachs, Box, etc)
• Sometimes referred to as GIFEE ("Google’s
Infrastructure for Everyone Else")

69. KUBERNETES
• All the benefits of Docker, but at
enterprise or "Web scale"
• Turn-key support from major cloud
providers (Google, Microsoft)
• Can run on-premise
• Bare metal
• OpenStack
• Kubernetes Federated Clusters!
• Hybrid cloud
• Multi-cloud

74. 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

75. CANARY RELASES

76. 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.
