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.
Internal Developer Platform (IDP)
A curated, self-service layer on top of cloud and CI/CD infrastructure that product teams use to ship services without filing tickets — paved roads that make the right thing the easy thing.

Docker Multi-Stage Builds PHP 5.0+ Dockerfile builds using multiple FROM stages — build dependencies (Composer, Node, test tools) in earlier stages, copy only production artifacts to the final minimal image.

Kubernetes for PHP Developers PHP 5.0+
The essential Kubernetes concepts PHP developers need — Pods, Deployments, Services, ConfigMaps, Secrets, and Ingress — for deploying and scaling PHP applications on Kubernetes.

nginx + PHP-FPM Production Config PHP 5.0+
The canonical nginx + PHP-FPM setup for PHP production — nginx handles static files and slow clients, PHP-FPM runs PHP via FastCGI, with proper timeout, buffer, and security settings.

On-Call Culture & Runbooks
Sustainable on-call practices — fair rotation, blameless postmortems, actionable alerts, and well-maintained runbooks that reduce mean time to recovery and prevent burnout.

devops intermediate
Shift-Left Testing
Moving testing earlier in the development process — catching bugs at the developer's machine and PR stage rather than in staging or production.

devops intermediate
Alerting & On-Call PHP 5.0+
Automated notifications triggered when SLIs breach SLO thresholds — effective alerting is actionable, low-noise, and tied to clear runbooks.

devops intermediate
Blameless Post-Mortem PHP 5.0+
A structured review of an incident focused on systemic causes and improvements, not individual blame — making it safe to surface failures.

devops intermediate
Blue/Green Deployment PHP 5.0+ Maintaining two identical production environments and switching traffic between them for zero-downtime releases and instant rollback.

devops intermediate
Canary Release PHP 5.0+ Gradually routing a small percentage of traffic to a new release, monitoring for issues before a full rollout.

devops intermediate
Container Security PHP 5.0+ Security practices for building and running containers — minimal base images, non-root users, read-only filesystems, image scanning, and runtime security controls.

Containerisation (Docker for PHP) PHP 5.0+ Packaging PHP applications and their dependencies into Docker containers for consistent, reproducible environments from dev to production.

devops intermediate
Continuous Deployment (CD) PHP 5.0+ Automatically deploying every commit that passes CI to production, eliminating manual release steps.

devops intermediate
Deployment Rollback Strategies PHP 5.0+ Strategies for reverting a broken deployment quickly — from git revert and re-deploy to instant traffic switching with blue-green or feature flags.

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.

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.

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.

devops intermediate
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.
