What is the difference between continuous integration, continuous delivery and DevOps? -

-

i hear these terms , wonder difference? how related continuous builds , continuous deployments?

continuous integration / continuous builds getting developers commit code source code repository little , (and latest version repository, further changes based on other developers recent changes). reduces time wasted on merge resolution, it's easier merge in case.

the process best automated using build server, can run unit tests. feedback provided developers in case of build / test failure, issues can fixed quickly.

continuous deployment involves automated deployment of build artefacts build process onto test , production environments. mitigate risk involved this, people use feature toggles separate release (in controlled way) deployment.

continuous delivery less technology , more organisations approach software delivery (although make heavy use of automation).

devops larger area emphasises breaking down barriers between developers , operations teams, , getting them collaborate in way benefit combined skills. more automation of environment provisioning, build deployment, monitoring (and reacting automatically problems , scalability), , in cases software defined networks come out of in company. in organisations, dedicated devops team(s) has been created.
