Some of the key features of DevOps architecture is:

1) Automation

Automation helps to reduce time during the testing and deployment phase. With automation, productivity increases, and releases are made faster. This helps in catching bugs quickly so that they can be fixed easily. For continuous delivery, each code drop is defined through automated tests, cloud-based services, and builds. The builds are deployed in production using automation, to reduce human errors caused due to manual deployment.

2) Collaboration

DevOps is a collaboration of the Development and Operations team. It improves the working model of the teams and they become more productive with their productivity, which strengthens accountability and ownership. The teams work in close collaboration sharing responsibilities, which in turn makes the deployment to production faster.

3) Integration

Software Applications need to be integrated with other components in the environment. The integration phase is where the existing code is combined/merged with new features/functionality and then tested. Continuous integration and testing enable continuous development. A significant operational challenge is faced in how frequently the releases are to be made. To cater to such problems, continuous integration and delivery are implemented. It ensures quicker, safer, and reliable deliveries.

4) Configuration management

Configuration management helps in building robust and stable systems for the engineering teams using tools that can automatically manage and monitor updates to the configuration data. The configuration file can be written during deployment(for the automated environment), or it can be loaded at the run time(manually), depending on the environment in which it is running.
