Devops terms
Shipping fast, breaking nothing, sleeping soundly
The gap between writing code and running it reliably in production is where DevOps lives. CI/CD pipelines, infrastructure as code, containerisation, deployment strategies, monitoring, and incident response — this category covers the culture, tools, and practices that let teams ship with confidence and recover quickly when things go wrong.

DevOps
A culture and set of practices that unifies development and operations teams to deliver software faster and more reliably.
2mo ago
devops beginner
DORA Metrics PHP 5.0+ Four metrics from the DevOps Research and Assessment team that predict software delivery performance: deployment frequency, lead time, change failure rate, and time to restore.

Feature Toggle Types Release toggles, ops toggles, experiment toggles, and permission toggles — each with different lifespans, owners, and removal disciplines.
2mo ago
devops intermediate
GitFlow vs Trunk-Based Development GitFlow uses long-lived feature and release branches; trunk-based development merges to main frequently — the latter scales better with CI/CD.
2mo ago
devops intermediate
GitHub Actions for PHP PHP 5.0+ Automating PHP CI/CD with GitHub Actions — running tests, static analysis, code style checks, and deployments on every push and pull request.
2mo ago
devops intermediate
GitOps PHP 5.0+ Using Git as the single source of truth for infrastructure and application state — changes are made via pull requests, and a reconciliation loop automatically applies them to the target environment.
2mo ago
devops advanced
Health Check Endpoints PHP 5.0+ Dedicated endpoints that report application and dependency status, enabling load balancers, container orchestrators, and monitors to route traffic correctly.
2mo ago
devops beginner
Immutable Infrastructure PHP 5.0+ Servers are never modified after deployment — to update, you build a new image and replace the old server entirely, eliminating configuration drift.
2mo ago
devops intermediate
Incident Response PHP 5.0+ A structured process for detecting, containing, investigating, and recovering from security incidents or system failures.
2mo ago
devops intermediate
Infrastructure as Code (IaC) PHP 5.0+
Managing servers, networks, and services through version-controlled machine-readable configuration files rather than manual processes.
2mo ago
devops intermediate
Infrastructure Drift
When the actual state of infrastructure diverges from its declared desired state — caused by manual changes, failed deployments, or out-of-band modifications that bypass IaC.
2mo ago
devops intermediate
Load Balancing PHP 5.0+ Distributing incoming requests across multiple servers to maximise throughput, minimise latency, and eliminate single points of failure.
2mo ago
devops intermediate
Observability (Logs, Metrics, Traces) PHP 5.0+
The ability to understand a system's internal state from its external outputs — built on three pillars: logs, metrics, and distributed traces.
2mo ago
devops intermediate
PHP Deployment Pipeline PHP 5.0+
A complete CI/CD pipeline for PHP — from push to production — covering lint, test, build, staging deploy, smoke test, and production release.
2mo ago
devops intermediate
Rolling Deployment
Gradually replacing old application instances with new ones, a few at a time, so the service remains available throughout the upgrade.
2mo ago
devops intermediate
Secret Rotation
The practice of periodically replacing cryptographic secrets, API keys, and credentials — limiting the window of exposure if a secret is compromised without triggering a breach.
2mo ago
devops intermediate
Semantic Versioning (SemVer) PHP 5.0+
A versioning scheme (MAJOR.MINOR.PATCH) where version numbers communicate the nature of changes to consumers.
2mo ago
devops beginner
SLA / SLO / Error Budgets (SRE)
SLA is the external promise; SLO is the internal target; error budget is the allowed downtime — together they guide reliability decisions.
2mo ago
devops intermediate
Three Pillars of Observability
Logs (events), metrics (measurements), and traces (request flows) are the three pillars of observability — together they answer 'what happened, how much, and where.'
2mo ago
devops intermediate
Trunk-Based Development
All developers integrate small, frequent commits directly into a single shared branch (trunk/main), avoiding long-lived feature branches.
