- 5. Where is the Problem?
- 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.
- 11. Solution, Is there any?
- 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
- 62. Source to Image (S2I)
- 63. Why Developers like OpenShift ● On-Demand Development – Self-Service and on-demand application stacks – Responsive Web Portal – One-Click application deployment ● Flexibility and Choice – Choice of programming languages and frameworks – Enterprise apps with Java EE6 – Built-in database services – Extensible cartridge system for adding services – Mobile application development – Application portability ● Standardisation – Standardised developer workflows – Multiple environment support – Dev/Test/Prod – Dependency and build management – Library of project templates ● Agile Development – Continuous Integration and Release Management – Source code version management ● Development Experience – IDE integration – Remote application debugging – Remote SSH login to application containers – Rich command line tools
- 64. Why Operations like OpenShift ● Designed for High Availability (HA) ● SELinux-based secure multi-tenancy support ● Enterprise integration – DNS, Directory Services, and edge of network services. ● Supports Continuous Delivery & DevOps – Automated provisioning – Automated application scaling – Reduced maintenance overhead – Embed operational standards into development
- 65. Why Business likes OpenShift ● Accelerated Application Service Delivery – Enhances team productivity and agility – Reduces project bootstrap & setup time – Engenders ready-to-deploy development of applications and services ● Minimises Vendor Lock-in – Build on a stack of open source technology – Provides freedom of choice over adopted languages and frameworks – Provides freedom of movement into and out of the platform; portable application development – No proprietary APIs, technologies or resources – No vendor lock-in
