5. Where is the Problem?

6. Rework & Overhead

7. Rework & Overhead
● Developer to QA lag
● Developers gets late feedback
● Works on a buggy software
● Resulted in REWORK
● Developers are paid to write code
● Not spend hours writing instruction how deploy,
thats OVERHEAD
● That leads to more problems....

8. Leads to more problems
● An INNOVATION problem
– We need to deliver more apps, more features, more value.
The business wants more out of IT.

9. Leads to more problems
● An INNOVATION problem
– We need to deliver more apps, more features, more value.
The business wants more out of IT.
● A THROUGHPUT problem
– We need to deliver value to the organization faster. Our
projects are always behind. My best people are always
fighting fires instead of delivering value.

10. Leads to more problems
● An INNOVATION problem
– We need to deliver more apps, more features, more value. The
business wants more out of IT.
● A THROUGHPUT problem
– We need to deliver value to the organization faster. Our
projects are always behind. My best people are always fighting
fires instead of delivering value.
● A QUALITY problem
– Our IT projects aren’t as successful as we want them to be. The
results aren’t satisfying the business.

13. What is DevOps?

15. What is DevOps?
● DevOps is not a Product
● DevOps is not a Technology
● DevOps is not brain surgery
● We Don't buy DevOps
● We do DevOps

16. DevOps Defined
DevOps is a culture, movement or practice
that emphasizes the collaboration and
communication of both software
developers and IT operations professionals
while automating the process of software
delivery and infrastructure changes.

17. DevOps Defined ….. in Short
Communication to work in more collaborative
way to achieve acceleration through automation
by bringing People, Process & Technology
together

18. You Improve 3 things
● Software that you deliver
● Environment that you are delivering
● Improve the Process

26. How DevOps Solve the INNOVATION,
THROUGHPUT & QUALITY Problem?

27. How DevOps Solve the Problem?
● INNOVATION
– Fully implemented, DevOps can help developers develop,
test & deploy new applications & features quickly to help
the business succeed.

28. How DevOps Solve the Problem?
● INNOVATION
– Fully implemented, DevOps can help developers develop,
test & deploy new applications & features quickly to help
the business succeed.
● THROUGHPUT
– DevOps tools and practices can help automate mundane,
repetitive tasks and free-up your smartest resources to get
new projects out the door more quickly.

29. How DevOps Solve the Problem?
● INNOVATION
– Fully implemented, DevOps can help developers develop, test & deploy
new applications & features quickly to help the business succeed.
● THROUGHPUT
– DevOps tools and practices can help automate mundane, repetitive
tasks and free-up your smartest resources to get new projects out the
door more quickly.
● QUALITY
– DevOps practices - like continuous feedback loops and continuous
integration - can help increase the quality of deployed code. And, if
something goes wrong, you can recover quickly.

30. Continuous Delivery / Continuous Deployment

31. Continuous Delivery / Continuous Deployment
● Continuous Deployment is process to deploy a
software to any particular environment at any
given point of time.

32. Continuous Delivery / Continuous Deployment
● Continuous Deployment is process to deploy a
software to any particular environment at any
given point of time.
● Continuous Delivery is that capability to deploy
software to any particular environment at any
given point of time and it is a must.

33. Continuous Delivery / Continuous Deployment
● Continuous Deployment is process to deploy a
software to any particular environment at any
given point of time.
● Continuous Delivery is that capability to deploy
software to any particular environment at any
given point of time and it is a must.
● Helps to recreate a bug aqap so that they can
fix it.

34. Continuous Delivery / Continuous Deployment
● Continuous Deployment is process to deploy a
software to any particular environment at any
given point of time.
● Continuous Delivery is that capability to deploy
software to any particular environment at any
given point of time and it is a must.
● Helps to recreate a bug aqap so that they can fix it.
● What they need is the ability to provision that
environment which has the same version.

35. How do we achieve Continuous Delivery?

36. Tools That can help you achieve this
● Docker
● Kubernetes
● OpenShift
● Puppet
● Ansible

37. Docker?

38. Docker?
A software to create and manage containers

39. Containers?

40. Containers?
Lightweight Operating System Virtualization

41. Docker
● Docker allows you to package an application
with all of its dependencies into a standardized
unit for software development.

42. How is this different from virtual machines?

43. Kubernetes?

44. Kubernetes?
Kubernetes is an open source container cluster manager by Google.
It aims to provide a "platform for automating deployment, scaling, and
operations of application containers across clusters of hosts".

45. OpenShift?

46. OpenShift?
OpenShift is a cloud Platform-as-a-Service
(PaaS) developed by Red Hat.

49. EVERYONE GETS ALONG
• Operations care about stability and performance
• Developers just want environments without waiting
OpenShift Enterprise creates a peaceful
environment for both
