DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle and provide continuous delivery of high-quality software.
DevOps is:
- A culture of collaboration between teams that historically functioned in relative siloes.
- A philosophy of unifying Development and Operations for improved workflow.
- A practice emphasizing the automation and monitoring of all steps of software construction, from integration, testing, and releasing, to deployment and infrastructure management.
- Collaborative Culture: Teams work together, share responsibilities, and combine their workflows to reduce inefficiencies.
- Automation: Repetitive tasks are automated, speeding up the development process and reducing the risk of human error.
- Continuous Integration & Continuous Delivery (CI/CD): Frequent integration of code changes into a shared repository, followed by automated testing and deployment.
- Monitoring & Feedback: Constant monitoring of applications and infrastructure performance, with real-time feedback into the development process.
- Source Code Management (SCM)
- Configuration Management
- Continuous Integration and Deployment
- Automated Testing and Monitoring
- Containerization and Microservices
- Source Control: Git, SVN
- Continuous Integration: Jenkins, Travis CI
- Deployment Automation: Ansible, Terraform
- Containerization: Docker, Kubernetes
- Monitoring: Nagios, Prometheus
- Collaboration and Communication: Slack, Microsoft Teams
- Faster, more reliable software releases.
- Improved collaboration and communication.
- Increased efficiency and reduced development lifecycle.
- Faster recovery from downtime.
By adopting a DevOps culture, along with associated practices and tools, organizations can break down siloes, improve collaboration, and deliver high-quality software more efficiently and effectively.
