right from the start software development comprise two different departments the development team that develops the plan designs and builds the system from scratch and the operation team for testing and implementation of whatever is developed the operations team gave the development team feedback on any bugs that needed fixing and any rework required invariably the development team would be idle awaiting feedback from the operations team this undoubtedly extended timelines and delayed the entire software development cycle there would be instances where the development team moves on to the next project while the operations team continues to provide feedback for the previous code this meant weeks or even months for the project to be closed and final code to be developed now what if the two departments came together and worked in collaboration with each other what if the wall of confusion was broken and this is called the devops approach the devops symbol resembles an infinity sign suggesting that it is a continuous process of improving efficiency and constant activity the devops approach makes companies adapt faster to updates and development changes the teams can now deliver quickly and the deployments are more consistent and smooth though there may be communication challenges devops manages a streamlined flow between the teams and makes the software development process successful the devops culture is implemented in several phases with the help of several tools let's have a look at these phases the first phase is the planning phase where the development team puts down a plan keeping in mind the application objectives that are to be delivered to the customer once the plan is made the coding begins the development team works on the same code and different versions of the code are stored into a repository with the help of tools like get and merged when required this process is called version control the code is then made executable with tools like maven and gradle in the build stage after the code is successfully built it is then tested for any bugs or errors the most popular tool for automation testing is selenium once the code has passed several manual and automated tests we can say that it is ready for deployment and is sent to the operations team the operations team now deploys the code to the working environment the most prominent tools used to automate these phases are ansible docker and kubernetes after the deployment the product is continuously monitored and nagios is one of the top tools used to automate this phase the feedback received after this phase is sent back to the planning phase and this is what forms the core of the devops life cycle that is the integration phase jenkins is the tool that sends the code for building and testing if the code passes the test it is sent for deployment and this is referred to as continuous integration there are many tech giants and organizations that have opted for the devops approach for example amazon netflix walmart facebook and adobe netflix introduced its online streaming service in 2007. in 2014 it was estimated that a downtime for about an hour would cost netflix 200 000 however now netflix can cope with such issues they opted for devops in the most fantastic way netflix developed a tool called the simeon army that continuously created bugs in the environment without affecting the users this chaos motivated the developers to build a system that does not fall apart when any such thing happens so on this note here is a quiz for you match the devops tool with the phase it is used in a b c [Music] d none of the above today more and more companies lean towards automation with the aim of reducing its delivery time and the gap between its development and operations teams to attain all of these there's just one gateway devops and if you're also looking forward to doing the same and excel in devops check out simply learn's post-graduate program in devops design and collaboration with caltech ctme the program can help you master several in-demand devops skills and tools like continuous integration and delivery devops on cloud kubernetes docker and much more we hope you enjoyed this video if you did a thumbs up would be really appreciated here's your reminder to subscribe to our channel and to click on the bell icon for more on the latest technologies and trends thank you for watching and stay tuned for more from simplylearn you
