Problems in Managing Infrastructure
"   Configuration Drift
"   Changes causes Outages
"   Wall of Confusion – Dev and Ops
"   Non Functional Requirements:
•  Backups, security, monitoring, synchronization,
performance, capacity planning
" Dev,Test and Prod – All Different Environments
"   Mystery Machine: On But don’t know why?
"   Code Complete != Production Ready

Infrastructure is Hard !!

Old Problem: Infrastructure is Hard

"   Proprietary Solutions

"   Solve very little of the problem
"   Enterprise Focused
"   Large Professional Services Bills
"   On-premise
"   Acquired by companies with large consulting
organizations
"   Google, Amazon, Microsoft built their own tools
but its secret sauce
"   Proprietary Solutions

Infrastructure is Changing !!

Cloud Computing

New Problem: Infrastructure is
Changing
"   Easier to get .. but harder to manage
"   Demand is dynamic
"   Developers are crucial to Operations
"   Web/Cloud services are proliferating
"   Manual Configuration no longer a crutch
"   Few tools solve all the problems
"   No Shrink Wrap software

Infrastructure is Code
"   API Driven Abstractions
"   Infrastructure is now an Application
App LBs
App Servers
NoSQL
DB slaves
Cache
DB Cache
DBs

Agile Infrastructure:
The Final Frontier for Agile

Agile Infrastructure
"   Infrastructure is Code: Apply the lessons learnt
from Software Development
"   Build more Flexible systems and faster
feedback
"   Beyond Continuous Integration: Continuous
Delivery
"   10+ deploys per Day – Flickr, 2009

Amazon.com
"   Mean time between deployments: 11.6s
"   Max # of deploys per hour : 1079
"   Mean # of host simultaneously receiving a
deployment: 10,000
"   Max # of hosts receiving a deployment: 30,000

Agile Infrastructure Techniques
u Configuration Management
u Version Control Everything
u Build from source
u One step deploy
u Monitoring
u Continuous Delivery
u Work Together – Dev and Ops

What is Infrastructure (again) ?
• Nodes
• Networking
• Files
• Directories
• Symlinks
• Mounts
• DB Schema
Infrastructure is a collection of resources:
•  Routes
•  Users
•  Groups
•  Tasks
•  Packages
•  Software
•  Services
•  Configurations
•  Stuff

Infrastructure as Code (really?)
package "ntp" do!
action :install!
end!
service "ntpd" do!
action [:enable,:start]!
end!
template "/etc/ntpd.conf" do!
source "ntpd.conf.erb"!
owner "root"!
group "root"!
mode 0644!
action :create!
variables(:time_server =>
“time.example.com”)!
notifies :restart, “service[ntpd]”!
end!

Configuration Management
"   Infrastructure as Code
"   Put systems into a known state
"   Audit and enforce consistency
"   Manage server lifecycle
"   Reason about services, instead of systems
"   Apply dev-test-prod cycle to infrastructure

Configuration Management Tools

Version Control Everything
"   Network Configurations
"   System Configurations
"   Application Configurations
"   Application Code
"   Database Schema
"   Documentation
"   Anything else that matters!

Build from Source
"   Build Application and Infrastructure from
source
" Dev,Test and Prod in sync
"   Test from a known state
"   Scaling
"   Disaster Recovery

One Step Deploy
"   One automated process from version control to
live services
"   Lower the time and cost to deploy

Monitoring
"   Define ‘Normal’ Conditions
"   Monitor Baselines, Charts, trends
"   Monitor, Monitor and Monitor !

Continuous Integration
"   Check in regularly
"   Create an automated and comprehensive test
suite.
"   Test New builds
"   Assert Services are running
"   Deploy early and often
"   No manual steps!
"   Never go home on a broken build
"   Build a pipeline!

Work Together – Dev and Ops
" Dev and Ops see the same thing, in the same
place
"   Share Metrics
"   Share the Repository
•  Configs in sync with Application Code
"   Minimize Surprise
"   Always ship trunk/master

How often do we see this?

Work Together – Dev and Ops
" Devs need to understand the infrastructure
"   Ops needs to understand the Application
"   Manage Flows – Avoid Fires
"   Build a culture – Avoid the blame game
"   Break the silos and work together!
"   Collaboration: not only when things go wrong
"   No Rock star mentality

What is DevOps ?
DevOps:
is a software development method that stresses
communication, collaboration and integration
between Dev and Ops.

What is DevOps ?
DevOps really is:
"   Processes
"   Tools
"   Culture

DevOps
"   Processes and Tools
•  Automated infrastructure
•  Shared version control
•  One step build and deploy
•  Shared metrics
"   Culture
•  Respect
•  Trust
•  Healthy attitude about failure
•  Avoiding Blame
•  Superhero Culture

Conclusion
ü  Agile Infrastructure
ü  Embrace DevOps
ü  Business Agility
ü  Improved Time to Market
ü  Ahead of the competition
