Dev
The Developers focus their efforts on ‘pushing out code.’ Changes and enhancements to production systems and attendant failures in providing service are seen as part of this rush to get the latest and greatest code out to consumers.
Ops
The Operations groups, on the other hand, are “reactive.” They are focused on service management and incident response. Teams supporting operations tend to use organization models closely aligned with ITSM and ITIL.
How DevOps Works
Under a DevOps model, development and operations teams are no longer “siloed.” Sometimes, these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function. In some DevOps models, quality assurance and security teams may also become more tightly integrated with development and operations and throughout the application lifecycle. When security is the focus of everyone on a DevOps team, this is sometimes referred to as DevSecOps.
Speed
Move at high velocity so you can innovate for customers faster, adapt to changing markets better, and grow more efficient at driving business results. The DevOps model enables your developers and operations teams to achieve these results.
Rapid Delivery
Increase the frequency and pace of releases so you can innovate and improve your product faster. Continuous integration and continuous delivery are practices that automate the software release process, from build to deploy.
Relibility
Ensure the quality of application updates and infrastructure changes so you can reliably deliver at a more rapid pace while maintaining a positive experience for end users.
Scale
Operate and manage your infrastructure and development processes at scale. Automation and consistency help you manage complex or changing systems efficiently and with reduced risk.
Improved Collaboration
Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows.
Security
Move quickly while retaining control and preserving compliance. You can adopt a DevOps model without sacrificing security by using automated compliance policies, fine-grained controls, and configuration management techniques.
Continuous Integration
Continuous integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run. The key goals of continuous integration are to find and fix bugs faster, improve software quality, and reduce the time it takes for new updates
Continuous Delivery
Continuous delivery is a software development practice where code changes are automatically built, tested, and prepared for a release to production. It expands upon continuous integration by deploying all code changes to a testing environment and/or a production environment after the build stage.
