What is DevOps ?
Let us find it on Web
A Simplified Answer to What is DevOps ?
WhiteHedgeManufacturing a Car
Manufacturing a car is like building a
A car is designed, each parts of the car built separately,
which are assembled together and delivered to the showroom for sale.
Every car sale also follows with Service and Support.
WhiteHedgeLets draw an analogy
Car parts are manufactured using machinery
Software is better written when written with the help of tools
Car Testing. Test parts of car, test assembled car, test car
Machines used for manufacturing in automotive
DevOps in Software industry
is like the
which helps you
Where to Start with DevOps ?
WhiteHedgeSTEP 1 : Make a START
Learning DevOps is like learning to Ride a Bicycle.
You learn to balance, Only when you are in MOTION!
WhiteHedgeMake a Start to Realize
DevOps replaces human tasks
There are no limits to what you can automate
You will be creating Robots
You need to be creative, innovative
You need to be techy too
WhiteHedgeSTEP 2 : Change
Start with a clean slate
Keep your past behind
Be ready for change
Understand you need to: learn-unlearn-learn-repeat
Keep your mind open
Be proactive, you need to drive yourself
DevOps brings in a new culture
You won't have any requirements
You won't be given any design
You won't be shown any problem
A lot of ideas would be thrown at you
And you would be called to help!
WhiteHedgeSTEP 3 : Dehumanize !
Follow the mantra: Any task should be done only once!
Start by writing small scripts to automate any task you would have to do
If it can't be scripted, document it
The challenge should be: the 2nd time you have to do the same task, it should
take 10 times less time than the first attempt!
WhiteHedgeSTEP 4 : Understand Fundamentals !
DevOps is here to automate nearly everything
But you can start with some tasks which are the bare minimum needs of
Next few slides will explain these fundamental concepts
Source Code Version Control
Github is the most popular
Keep in mind that Version Control can also be applied to infrastructure,
configuration and databases, but this can be studied in depth in later stages
of your Learning & Implementing DevOps!
Few popular tools
CI enables early detection of problems in integration. It includes several
components, explained further
Automated Code Review
Automated Code Analysis
Automated Unit Tests
Automated Integration Tests
WhiteHedgeAutomated Code Review and Analysis
Don't go by the dull title. This is quite interesting when implemented.
It keeps the developers code on track and reduces code quality issues!
Tools like Gerrit can be used for setting up code review process
Go through the concepts and explore the tools listed below
Static Code Analysis
Build tools convert source code to binary, create executables (eg: jar), can run
tests and create documentation. Listed below are some popular build tools.
Understand any one build tool to know the intricacies of building a project.
WhiteHedgeArtifact Management Repository
Artifacts are generated as a result of the builds. They can also be called as
application or executables
Artifacts are also those libraries needed by the build (called dependencies)
We need to control the version of the dependencies
We need to manage releases of the application
Hence artifact management is important
Explore the existing popular solutions:
Artifactory (PaaS offering)
Continuous Integration server can be setup in-house or used as a PaaS
Try some hands-on with both CI servers mentioned below
This literally translates to Infrastructure Automation
Following are the 3 most popular CM tools. Study 2 of them well.
Puppet OR Chef
CD is a natural extension to CI: Teams can ensure that every change to the
system is releasable and that any version can be released at the click of a
With the concepts we have learnt so far, you would realise that we would end up with many versions of the build.
We want to release the right versions, frequently, and get a feedback about how it performs. This is release management.
The solution to deployment and release management differs for every use case. CM tools like Ansible can be used
CI Server like Jenkins can be used
Capistrano is a standalone tool
Understand theoretically how each of the above works. Note the differences in each approach and which would be used in which use cases.
Application and System Monitoring are one of the important tenets of DevOps.
Explore some of the tools below, try some hands-on:
WhiteHedgeAssignment: Setup a CI/CD Pipeline
Create a Hello World project on Github
Use hosted Travis-CI as build server
With every git push:
Hello World build should be triggered in Travis-CI
Run unit tests
If they pass, save the build output to Nexus
Trigger a playlist in Ansible, which will deploy the build to a another machine
With every successful deployment, relay the feedback (send emails)
With a failure in any of the steps, send the feedback to the developer with the details of failure
