- 21. Disadvantage of DevOps o Tools are brand new to the market or are open-sourced. o Relying on an external Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) provider. This reliance reduces control and visibility at the hardware and network layers. o Complicate the tracking of hardware assets over time.
- 22. DevOps and Agile That's fundamentally not true as well. DevOps is actually highly related to Agile development processes. So, as we can see, Agile introduced the concept that we need to iterate in software development, that we need to move through our cycles in an iterative fashion, that we need to have incremental changes and adapt and react to change quickly and flexibly to make o DevOps is Agile:
- 23. DevOps and Agile o DevOps is an Extension of Agile Thinking? the DevOps answer to that was to embed operations into the development process. Take experts from the operations teams and put them into the product team. Make them involved in every decision. And when DevOps came on the scene, the primary idea was remarkably similar, to embrace constant delivery, to embrace testing, to embrace operations.
- 24. o Operations IT operations include system administrators, database administrators, network engineers, infrastructure architects, and support personnel. DevOps and Agile

- 31. Testing is a critical part of the handoff between development and IT operations. Successful Agile teams using DevOps practices fully integrate testing into their software development lifecycle. How Testing Fits into the DevOps Toolchain
- 32. A test-driven development system creates confidence that when all of the automated tests pass, the code is good to go. Successful DevOps toolchains include a fully automated test harness that can signal to both development and IT operations teams when code that’s in development and code on running systems is passing (or failing) their tests. How Testing Fits into the DevOps Toolchain
- 33. o o bring in talented testers. o then deploy them wisely. o Make sure they test API services for business logic and processes to maximize the benefits of automation. Improve testing inside your Agile environ ment
- 35. Development Operations Change »Developers introduce changes »They try to implement every new techniques introduced »Change is the enemy for Operations »Changes can lead to instability Why DevOps?
- 36. »Difficult to integrate tools »Less interest in learning each others tools »Different implementation of similar tools Why DevOps? Confusion
- 37. Development Operations Sends out files based on requirements Manually hacks the scripts received and changes the configuration files to reflect changes in production which could potentially lead to an issue.Why DevOps? During Deployment
- 38. Operations Development Developer gave faulty artifacts. All the files are fine, the error is because of some other issue Why DevOps? Loss Work
- 39. After deployment, QA sees some anomalies and raises defects Developer realizes that correct files was not deployed Operations Development Why DevOps? After Deployment
- 40. Why DevOps? Benefits Of DevOps o Continuous software delivery More deploys means faster time-to-market and continual improvement. o More stable operating environments You don’t have to choose stability versus new features. A single team is responsible for delivering new features and stability.
- 41. Why DevOps? Benefits Of DevOps o Less complex problems to fix Because change sets are smaller. o Faster resolution of problems Because team members don’t need to wait for a different team to troubleshoot and fix the problem.
