DevOps is a set of automated to shorten the software development lifecycle

DevOps (a portmanteau of Development and Operations) is a set of cultural philosophies, practices, and tools that combines software development (Dev) and IT operations (Ops). Its core goal is to shorten the systems development lifecycle and provide continuous delivery with high software quality. ​Core Pillars & Principles ​Culture of Collaboration: Breaks down traditional silos between software developers and IT infrastructure teams, sharing responsibilities for both application code and operational stability. ​Continuous Integration & Continuous Delivery (CI/CD): ​CI: Developers regularly merge code changes into a central repository, where automated builds and tests run. ​CD: Code changes are automatically prepared, tested, and released to production environments reliably at any time. ​Infrastructure as Code (IaC): Managing and provisioning infrastructure (servers, networks, storage) through code and software development techniques rather than manual configuration. ​Automation: Automating repetitive tasks—such as testing, deployments, monitoring, and provisioning—to reduce human error and increase release speed. ​Continuous Monitoring & Feedback: Collecting performance metrics and logs from live applications in real time to proactively identify bugs and iterate on improvements. ​Key Technical Components & Tooling DomainKey ConceptsIndustry Tools Version ControlSource code management, branching strategiesGit, GitHub, GitLab CI/CD PipelinesAutomated build, test, and release automationGitHub Actions, GitLab CI, Jenkins ContainerizationPackaging applications with dependenciesDocker, Podman OrchestrationManaging container lifecycles at scaleKubernetes, Docker Swarm IaC & ProvisioningDeclarative infrastructure definitionTerraform, Ansible, AWS CloudFormation Monitoring & LoggingSystem health metrics, error tracing, aggregation
