WHAT IS DEVOPS?
“DevOps is the union of people,
process, and products to enable
continuous delivery of value to our end
users.”
- Donovan Brown

DEVOPS: DEFINITION
"DevOps" is an emerging set of principles, methods and practices for
communication, collaboration and integration between software
development (application/software engineering) and IT operations
(systems administration/infrastructure) professionals.

INTRODUCTION
 As per the application economy today, businesses have become
software businesses, and DevOps has become one of the most
valuable business disciplines for enterprises.
 With the help of DevOps, quality, and speed of application delivery
have improved to a great extent.

WHERE DID DEVOPS CAME FROM?
There are tons of stories about the DevOps origins, but it is not
created out of the whole cloth. Its seeds were planted many years
ago and recently nurtured by expert IT professionals in several
disciplines. Two primary ancestors of DevOps are given below:
1. ESM (Enterprise Systems Management): People involved in
the initial phases of DevOps are system administrators. These
experts brought the key ESM practices to DevOps like
configuration management, automated provisioning, system
monitoring, and the toolchain approach, etc.
2. Agile Development: DevOps can be considered as an
outgrowth of the agile. It is simply extending the Agile principles
beyond boundaries of the code to the entire delivered services.

BREAKING THE SILOS: DEV AND OP

WHAT IS DEVOPS ?
 DevOps word in itself is a combination of two words one is
Development and other is Operations. It is neither an
application nor a tool; instead, it is just a culture to promote
development and Operation process collaboratively.
 As a result of DevOps implementation, the speed to deliver
applications and services has increased.
 DevOps enables organizations to serve their customers
strongly and better in the market.
 DevOps is the process of alignment of IT and development
operations with better and improved communication.

PROBLEMS LED TO THE CREATION OF DEVOPS
 DevOps implementation has increased the rate of software
delivery and the revenue for business stakeholders. Following
listed reasons are the most considerable ones that led to the
creation of DevOps.
 Before DevOps, operation and development teams were working
in an isolated environment.
 Testing and Deployment activities mostly were performed in an
isolated manner after design-build step, and they took more time
than actual project completion time.
 Team members usually spend a large amount of time in deploying,
testing, designing, and building the projects
 Human production errors were deployed during manual code
conduction.

TRADITIONAL DEV AND OPS
VERSUS DEVOPS

DEVOPS LIFECYCLE PHASES (CONT.)
 Continuous Development:
Plan application objectives and Code the requirements
 Continuous Integration:
Plan Tests and Build the product
 Continuous Testing:
Verify the product for actual usage in a live environment
 Continuous Monitoring:
Monitor the product output and find the problem areas

DEVOPS LIFECYCLE PHASES (CONT.)
 Continuous Feedback:
Improvise the current product and helps to release new versions quickly
 Continuous Deployment:
Ensures product is deployed with maximum accuracy
 Continuous operations:
Automate release process with shorter development cycles
All DevOps operations are based on continuity with complete automation of the
release process and allow organizations to accelerate the overall time to market on
an ongoing basis.

BENEFITS OF DEVOPS (CONT.)
 Significant improvement in product quality: Collaboration between development and
operation teams and frequent capturing of user feedback leads to a significant improvement
in the quality of the product.
 Continuous delivery of software: In DevOps methodology, all of the departments are
responsible for maintaining stability and offering new features. Therefore, the speed of
software delivery is fast and undisturbed, unlike the traditional method.
 Minimal cost of production: With proper collaboration, DevOps helps in cutting down the
management and production costs of your departments, as both maintenance and new
updates are brought under a broader single umbrella.
 Ensure faster deployment: Faster and more frequent delivery of updates and features will
not only satisfy the customers but will also help your company take a firm stand in a
competitive market
 Fast and reliable problem-solving techniques: Ensuring quick and stable solution to
technical errors in software management is one of the primary benefits of DevOps

BENEFITS OF DEVOPS (CONT.)
 Lower Risk: Security aspects are incorporated in SDLC, and the number of
defects gets decreased across the product.
 Stability: DevOps implementation offers a stable and secure operational state.
 Maintainability: The process improves the overall recovery rate at the time of the
release event.
 Automation in repetitive tasks leaves more room for innovation: DevOps has
greater benefits when compared to the traditional model as it helps in detecting
and correcting problems quickly and efficiently. As the flaws are repeatedly tested
through automation, the team gets more time in framing new ideas.
 Promotes agility in your business: It’s no secret that making your business
agile can help you to stay ahead in the market. Thanks to DevOps, it is now
possible to obtain the scalability required to transform the business.

BENEFITS OF DEVSECOPS
 DevSecOps is an
approach to providing
security to applications
and infrastructure based
on the methodology of
DevOps, which makes
sure the application is less
vulnerable and ready for
users' uses.

BENEFITS OF DEVSECOPS (CONT.)
 Developers don’t always code with security in mind. With a DevSecOps mentality,
developers are enabled with enhanced automation throughout the software delivery
pipeline to eliminate coding mistakes and ultimately reduce breaches.
 Teams that implement DevSecOps tools and processes to integrate security into
their DevOps framework will be able to release secure software faster.
 Developers can test code for security and detect security flaws as code is written.
Automated scans can be initiated as part of code check-ins, builds, releases, or
other components of the CI/CD pipeline.
 By integrating with tools developers are already using, dev teams can more easily
improve the security aspect of web application development.

BENEFITS OF DEVSECOPS (CONT.)
The benefits of adopting security in DevOps:
 Reduction of expenses and Delivery rate increases.
 Security, Monitoring, Deployment check, and notifying systems from the beginning.
 It supports openness and Transparency right from the start of development.
 Secure by Design and the ability to measure.
 Faster Speed of recovery in the case of a security incident.
 Improving Overall Security by enabling Immutable infrastructure which further
involves security automation.

BENEFITS OF USING DEVOPS WITH CLOUD
• Easy Automation: Automation is an important aspect of the infrastructure management. Automating
processes by leveraging cloud helps to enhance the pace of automation, makes the process more
reliable, error free, robust and efficient, ultimately leading to reduction in time to market.
• Cloud Server Replication: Every cloud provider has some backup mechanism. Even then there is a
need to launch the servers manually and restore the backup on a different environment. Through
DevOps, this process can be automated.

BENEFITS OF USING DEVOPS WITH CLOUD (CONT.)
• Effective Monitoring: DevOps can trigger custom alarms and various monitoring alerts enabling you to
utilize resources more effectively.
• Orchestration: The Orchestration is a specialized way of automation. Orchestration tools such as Chef,
Puppet and Ansible are some of the intelligent tools in the market. They are independent of any of the
cloud providers and have their own defined standards, but could be easily integrated with all the
leading cloud providers. Integrating with cloud provides additional benefits such as automated server
provisioning, auto-scaling and so on.
• Rapid Deployment: DevOps focuses on solving the infrastructural problems with latest tools by building
custom logic and writing capabilities. DevOps helps to automate the whole process using single click build
tools that interact with the cloud services and get the tasks done without any errors.

limit business losses to get back on track sooner.
o If you want to improve problem solving capabilities at your organization, this is one of the business benefits
for DevOps that cannot be forgotten.

FINAL THOUGHTS: DEVOPS IMPLEMENTATION
OFFERS MANY ADVANTAGES FOR BUSINESSES
Chris DeGonia, Director of QA at
International SOS, said on a recent podcast
– “DevOps is definitely here to stay. It is
something that teams really need to get
their hands around if they are not already
working in DevOps space. Theyneed to
scale up or skill up in order to make it.
Because it’s not becoming a slower-paced
world,we’re certainly facing a faster-
paced world as we move forward.”
