OSDC 2014: Fernando Hönig - New Data Center Service Model: Cloud + DevOps
Jan 22, 2015
With this presentation we would like to show how the world is changing related to Applications Deployment and Infrastructure build models. After this presentation you would be able to improve quality and velocity of software release, and to synchronize development and staging environments with production environment using configuration management tools such as Chef; collect application performance metrics (APM) to view code impact changes with application monitoring tools such as New Relic, statsD, Graphite, or Cloud Monitoring; build workflows to automate routine maintenance tasks using workflow automation tools such as Rundeck and Jenkins, aggregate logs from all devices to identify patterns and spot anomalies using log aggregation tools such as logstash; manage caching needs with tools such as Memcache, Varnish and more. Multi-server environments are now provisioned in minutes instead of the hours it previously took without automation tools.

QUESTION:
How many of you are in the cloud?
3 MYTHS ABOUT CLOUD:
• Is not secure:– Truth: Public cloud is multi-tenant. You potentially could have noisy neighbors.
– Remediation: On-Premise cloud, Virtual Private Cloud, Hybrid Cloud
• Is too complex:– Truth: Different types of cloud, with differing levels of complexity.
– Remediation: Choose a cloud provider who can offer you tools and support
• Cloud is for everything:– Truth: Not all applications are suitable for cloud computing.
– Remediation: There will be situations where security requirements, flexibility, performance or control will preclude the cloud
SCENARIO
BE READY..
Let’s focus on..• Server Automation
• Configuration Management
• Everything as a Code
• Code Repositories
• Testing Overview
• M-T-V
• Money
• Time
• Value
CLOUD + DEVOPSNEW DATACENTER SERVICE MODEL
AUTOMATE YOUR SERVERS
Everything IS code!
Treat your Servers as Commodities
No Server should be “special”• Should be no “droideka”, “skywalker”, “backup01” names
You might be able to remove a server with zero consequences
QUESTION:
How many of you use configuration management tools?
AUTOMATE YOUR SERVERS
Configuration ManagementCreates exactly what you needConforms a Server to a RoleMaintains State
QUESTION:
How many of you use continuous integration tools?
EVERYTHING AS A CODE
Code repositoriesCreate the same Development lifecycleYour Server code is also an application!
M-T-V
M-MoneyNo need to buy expensive toolsNo “deployment nights/weekends” anymoreLess outage
T-TimeSpeed up your deployment cycle
V-ValueCode TestedCommon goal across organizations
DevOps!• Culture and Work methodology
• Set of tools

CONTINUOUS INTEGRATION
If you write it TEST it!Continuous Integration gives you assuranceSet on good behaviors
SERIOUSLY.. TEST IT!
IT WORKED FINE IN TEST
CONTINUOUS INTEGRATION
• Also known as CI
• Perform all tests automatically for every piece
of code
• EVERY SINGLE ONE
CONTINUOUS INTEGRATION
CONTINUOUS DEPLOYMENT
• Also known as CD
• It’s an optional extension to CI
• Once a piece of code has been through CI
releases it automatically
• Very useful for bugs and minor changes
CONTINUOUS DEPLOYMENT
Releases per day 30+ 100+ 20+ 2+

HOW TO WIN?
Automate Everything!
HOW TO WIN?
Plan to fail!
HOW TO WIN?
DevOps teams spend more time
improving things and
less time fixing things
HOW TO WIN?
DevOps teams recover
from failures
FASTER!
HOW TO WIN?
DevOps teams release apps
more than twice as fast
