This document discusses DevOps, including what it is, its principles, challenges and benefits. DevOps aims to bridge the gap between development and operations through communication, collaboration and automation. It allows for rapid product evolution, improved quality and reduced costs and risks. DevOps principles include developing in similar environments to production and frequent, validated deployments. Challenges include release management and coordination, which DevOps addresses through continuous integration, delivery and automation tools. When to adopt DevOps includes ecommerce and websites, but not critical platforms like banking systems.

DevOps
 A software development method which is a combination
of Development and Operations(IT professionals).
 It involves the aspects like:
• Communication.
• Collaboration.
• Integration.
 It leads in the following outcomes:
• Rapid evolution of products or services.
• Reduces cost/Cost effective.
• Improves quality.
• Reduces the risk of the project.

DevOps
 DevOps integration targets at product delivery , quality testing,
maintenance etc., which helps in faster development and security
factors and also in faster deployment cycles.
 DevOps is driven by factors such as:
• Use of the agile and other methodologies.
• Increase in production releases by the project/stakeholders.
• Wide availability of cloud infrastructure.
• Increased usage of data center automation and also
configuration management tools.

Principles of DevOps
• Develop and test the application in an environment similar
to that of production environment.
• Deploying the builds frequently.
• Validation of the quality continuously or rigorously.

Why Gap?
 Development perspective view:
• Delivery of the application after testing in
development systems.
• Mismatch in the systems environment i.e.,
development system is not same as production
environment.
• Developers will have faster turn around time with
respect to the application/project.
• Not much concerned on infrastructure and also the
code changes on deploying the production.

Why Gap?
 Operations perspective view:
• Worries more about PSR.
• Lesser turn around time with respect to the
deployment and testing(Builds).
• Very much concerned on infrastructure and also the
code changes on deploying the production.

• Dev work with Ops to understand the impact of
code changes.
• Developers will work closely to the production
environment.
• Focus on the Ops requirement like PSR.
• More clarity on the infrastructure needs.
• Monitoring of the Dev-Test-Ops pipeline and
deployment which leads in getting immediate
feedback.
• Better collaboration and communication.
Solution

 Release Management.
 Release/Deployment co-ordination.
 Release/Deployment automation.
 Release management is with respect to understanding
risks, dependencies, issues.
 Release co-ordination is in terms of activities,
documentation and reporting etc.
 Flexibility of automation scripts with respect to the
production environment.
Challenges

12. Addressing the Challenges

13. DevOps and Agile
DevOps
Addresses the gap between dev + testing and ops.
Automated release management process.
Focus is on functional, non-functional, operational and
business.
 Reusability.
Agile
Addresses the gap between customer requirements and
dev + testing .
Teams to design, develop and test features prioritized by
the customer.
Focus is on functional and non-functional, operational.

15. Continuous Integration and Continuous Delivery
• Continuous integration (CI) is a software engineering
practice in which isolated changes are immediately tested and
reported on when they are added to a larger code base.
• Continuous integration software tools can be used to
automate the testing and build a document trail.
• Continuous delivery (CD) is a software engineering
approach in which teams produce software in short cycles,
ensuring that the software can be reliably released at any
time.
• It aims at building, testing, and releasing software faster and
more frequently.

16. Benefits of DevOps
• Increased service quality.
• Increased reliability of service delivery.
• Increased customer value through responsiveness to change.
• Better usability increases customer satisfaction
• Efficient operations
• Value creation increases employee satisfaction
• Collaboration improves employee attitude
• Constant learning and improvement
