Question 21. How Do All These Tools Work Together?

Answer :

Given below is a normal logical float wherein the entirety gets automated for seamless shipping. However, this glide might also range from organisation to enterprise as in keeping with the requirement.

Developers increase the code and this supply code is controlled by Version Control System tools like Git etc.
Developers send this code to the Git repository and any adjustments made within the code is committed to this Repository.
Jenkins pulls this code from the repository the use of the Git plugin and build it the use of equipment like Ant or Maven.
Configuration control equipment like puppet deploys & provisions testing surroundings after which Jenkins releases this code on the take a look at environment on which checking out is done using equipment like selenium.
Once the code is examined, Jenkins ship it for deployment on the manufacturing server (even production server is provisioned & maintained by means of tools like puppet).

To achieve this, groups are required to:

Increase deployment frequency
Lower failure price of new releases
Shortened lead time among fixes
Faster suggest time to healing inside the occasion of latest launch crashing
DevOps fulfills these kinds of requirements and enables in reaching seamless software shipping. You can deliver examples of organizations like Etsy, Google and Amazon that have adopted DevOps to achieve degrees of overall performance that had been unthinkable even 5 years in the past. They are doing tens, masses or even hundreds of code deployments consistent with day whilst handing over world class balance, reliability and safety.
