What are REST APIs?
Today’s enterprise IT looks like this.

What are REST APIs?
A simplified look at the enterprise

Challenges with current Business model
 Everything needs software nowadays.
 Software has to run on a server to become a service.
 Delivering a service from inception to its users is too slow and error- prone.
 There are internal friction points that make this the case.
 This loses you money. (delay = loss) IT is frequently the bottleneck in the transition of “concept
to cash.”

Why ? Reason !
 Defects are released into production, causing outages.
 Inability to diagnose production issues quickly.
 Problems appear in some environments only.
 Blame shifting/finger pointing.
 Long delays while dev, QA, or another team waits on resource or response from other teams.
“Manual error” is a commonly cited root cause. Releases slip/fail. Quality of life issues in IT.

Why ? Reason !

What is DevOps ?

DevOps is -
DevOps is not about IT problems: DevOps is about business
problems.

The three pillars of DevOps
 Infrastructure Automation
 Continuous Delivery
 Reliability Engineering

Infrastructure Automation
 Infrastructure provisioning
 Application deployment
 Runtime orchestration

Continuous Delivery
Integration (CI): Build and test
Deployment (CD): Deploy and integration test
Delivery: All the way to production

Reliability Engineering
 Operate for Design
 Enhance Service Design With Operational Knowledge
 Foster a Culture of Responsibility
 Make Development Better With Ops

Tooling
 Version Control (git, others, doesn’t matter as long as you use it)
 CI System (jenkins, bamboo, circleCI, travisCI)
 Build (whatever your platform needs - make/rake, maven, gulp,
packer)
 Test (*unit, robot/protractor, cucumber)Artifact Repository (artifactory,
nexus, dockerhub, S3)
 Deployment (rundeck, ansible, your CM system)

What will I achieve?
 Builds trust between the development and operations team which brings a change in the
attitude towards pursuing the tasks.
 Improved value to the customer feedback with quick turnaround.
 Increase in efficiency, quality and reliability with the automation.
 Cost effective and speedy delivery of a product to market.
 Increase in the Business revenue.

Conclusion
In conclusion, DevOps is a culture that improves the collaboration between Development and
Operations teams. Enabling DevOps improves the speed of the delivery according to the business
and customer needs. Especially automation in DevOps improves the productivity, reliability and
allows standardizing the process, which in turn plays a major role in product delivery for
organizations.
