DevOps is an emerging model of product delivery and full lifecycle management that emphasises a holistic, end-to-end process. We view it as the “engine room of change” that allows new ideas to be delivered quickly.
DevOps not only seeks to remove the silos between Development and Operations, but all of the key stakeholders in the application lifecycle.
It involves small teams from software and operational disciplines working collaboratively with each other and the business community to deliver deployable applications that will run and scale reliably, maximising payback. DevOps also involves introducing software automation tools to improve the speed, quality and reliability of the software deployment process.
Traditional models of application development and service delivery, which have multiple handovers between silos, face challenges when trying to achieve higher rates of change. Some of these existing models of delivery such as PRINCE2 and ITIL are over 20 years old, and pre-date many of the recent innovations in IT such as the Cloud, Infrastructure as Code, software defined networking, improved version control and collaboration tools.
Benefits Of DevOps:
Early detection of failure
Better Resource Utilization
Faster time to Market
Transparency in execution
Single click dployment
Promoted Builds
Governance with approval bassed releases.
Automated approach.
Quality releases
Enhanced recovery time.
Productivity gains
Decision support
7 Cs of DevOps
1)Communication
2)Collaboration
3)Controlled process
4)Continuous Integration
5)Continuous Deployment & Delivery
6)Continuous Testing
7)Continuous Monitoring
What is CI?
Continuous integration is a development practice that requires developer to integrate code into a shared repository several times a day.
Each check in is the verified by an automated build, allowing teams to detect problem early.
By Integrating regularly, you can detect errors quickly, and locate them more easily.
What is Continuous Delivery ?
Continuous delivery is a DevOps Software development practice where code changes are automatically built,tested, and prepared for a release to production with manual approval process.
What is Continuous Deployment?
If the approval process becomes automated then after staging, the code change is done directly to production system this is called continuous deployment
