The advent of cloud computing has changed the way applications are being built, deployed and hosted. One important development in recent years has been the emergence of DevOps — a discipline at the crossroads between application development and system administration.
Empowered developers have been given a wide new set of tools to enable:
- Application lifecycle management with continuous integration software like Jenkins, Travis CI, CircleCI, and CodeShip;
- Server provisioning with software and metadata using configuration management tools like Chef, Puppet, Salt, and Ansible;
- Hosting applications in the cloud, whether they use an IaaS provider like Amazon Web Services, Google Compute Engine, or Digital Ocean, or a PaaS solution like Heroku, Google App Engine, or any technology-specific offering.
