How Does Software Development Take Place?
So, What Is The Solution?

DevOps Strategy
DevOps involves Continuous Development, Continuous Testing, Continuous Integration, Continuous
Deployment & Continuous Monitoring of the software throughout its development lifecycle.

DevOps Tools In Context
Should we
learn all
these Tools??
NOPE !!
Learning 1 Tool from
various phases is
good enough

Demand For DevOps Engineers

Git & GitHub

What Is Git & Its Explanation
Git is a Distributed Version Control System for tracking changes in computer
files and coordinating work on those files among multiple users.

Case Study: Why & How Orbitz Moved To Git
1. Over 40 feature teams working in parallel
2. Developers use a centralized VCS for
working on same code base
3. The VCS was not scalable
4. Developer to code Deployer ratio is 50:1
Challenges
Orbitz Worldwide is an online travel site operating in over 180 countries.
Downtime of even 1 second will result in loss of millions of dollars.
Git’s Distributed VCS helped in Scaling systems globally
Git helped in achieving increased automation
Git allows developers to branch and merge flexibly
Git helped decrease build time by more than 20%
Implementation of Stash, a Git repo management solution

Maven, Selenium & TestNG

Tools Used For Continuous Testing In DevOps
DevOps Lifecycle →
Process of automating the execution of test cases is called Automation Testing.
Scheduling Automation Tests after every feature update is called Continuous Testing.

Maven For CT
• Helps in easily managing the project structure, its dependencies & test cases
• Can automatically download the necessary files & dependencies from the
repository
• These details need to be specified in the pom.xml file

Selenium For CT
• MAIN TOOL for testing the web application
• But has limitations like: Test case management & Report generation
• Hence tools like Maven, TestNG & Jenkins are integrated with it
SeleniumWebDriver

TestNG For CT
• Used with Selenium WebDriver for overcoming limitations:
• Test Annotations for managing Test Cases
• Generates structured Test Reports
• Helps perform Unit Testing

Jenkins For CI
• Tool responsible for Continuous Testing
(Automates Test Execution)
• Schedules builds and deploys the code to prod or staging server
• Integrates seamlessly with most testing tools
Jenkins

Hands-On
Continuous Testing

Jenkins For CI

What Is Jenkins?
Jenkins is a Continuous Integration
tool for automation various stages
in DevOps lifecycle. Automation is
achieved by using Plugins to various
tools involved in the process.

Source Code
Repository
Feedback
1. Developers commit changes to the source code
2. Continuous Integration server pulls that code and triggers a build
3. The build application is then deployed on the testing server for testing
4. After testing the application, it is then deployed on the production server
5. The concerned teams are constantly notified about the build and test results

Jenkins Case Study: Nightly Builds At Nokia
1. In Nokia, a process called Nighly Build was used.
2. In this process, every night an automated system pulls
the code added to the shared repository throughout
the day and builds that code.
3. Since the code that was built at night was quite large,
locating and fixing of bugs was a real pain.
Challenges

Jenkins Case Study: Nightly Builds At Nokia
1. Nokia adopted Continuous Integration (CI).
2. As a result, every commit made to the source code in
the repository was built.
3. If the build result shows that there is a bug in the code,
then the developers only need to check that particular
commit.
Solution

Continuous Deployment
Using Docker

What Is Docker?
Docker is a Containerization platform which packages your application & all its dependencies together in the form of
Containers, to ensure that your application works seamlessly in any environment be it Development/ Test/ Production.
• RAM consumed by containers is << RAM consumed by VMs.
• Easily run applications by packaging them into containers.
• Containers are light-weight; can be easily shared via Docker Hub.
BENEFITS

How Do We Create Docker Containers?
Docker files are used to build a Docker image & that image will also contain all the project codes.
The same Docker image can be used to spin ‘n’ no of containers, each with modifications to the underlying image.
This final image can then be uploaded to Docker Hub & shared with other collaborators for testing/ deployment.

Continuous Deployment
Using Ansible

What Is Ansible?
Ansible is a Configuration Management, Deployment & Orchestration tool which automates
your entire IT infrastructure. It is a “Push-based” configuration management tool.
