DevOps is a set of practices, tools, and a cultural philosophy that automates and integrates the processes between software development (Dev) and IT operations (Ops). The main goal of DevOps is to shorten the system development life cycle and provide continuous delivery with high software quality
- Collaboration: DevOps fosters a collaborative culture between development and operations teams, breaking down silos and enabling them to work together efficiently.
- Continuous Integration and Continuous Deployment (CI/CD): CI/CD pipelines automate the process of integrating code changes and deploying them to production, allowing for frequent, reliable software releases.
- Automation: Automation of repetitive tasks, such as testing, deployment, and infrastructure management, is central to DevOps. This reduces human error, speeds up processes, and ensures consistency.
- Monitoring and Logging: DevOps emphasizes the importance of monitoring applications and infrastructure in real-time, gathering logs, and using this data to improve performance, stability, and security.
- Infrastructure as Code (IaC): This practice involves managing and provisioning computing infrastructure through machine-readable scripts, rather than through physical hardware configuration or interactive configuration tools.
- Microservices Architecture: DevOps often goes hand-in-hand with microservices, where applications are broken down into smaller, loosely coupled services that can be developed, deployed, and scaled independently.
- Faster Delivery: Automation and continuous processes help speed up the delivery of software.
- Improved Collaboration: By fostering a culture of shared responsibility, teams work better together.
- Higher Quality Software: Continuous testing and monitoring help catch issues early, leading to more reliable software.
- Scalability and Flexibility: Automated processes allow for scaling up or down with ease, adapting quickly to changes.
- CI/CD: Jenkins, CircleCI, GitLab CI
- Configuration Management: Ansible, Puppet, Chef
- Version Control: Git, GitHub, GitLab
- Containers and Orchestration: Docker, Kubernetes
- Monitoring: Prometheus, Grafana, Nagios
