Nexus Pathway is a course that helps you move from "local developer" to "production-ready engineer" in Ruby. 🌐After Zenith Pathway, you know how to build clean architecture and test code. Now it's time to cover everything that happens after "bundle exec rails s": deployment, monitoring, security, legacy handling, observability, and avoiding common production pitfalls. What’s included9 modules with videos, real production examples, configs, scripts, exercises on tool setup, and real incident analysis.Module 1: Advanced tooling & environment managementrbenv vs rvm vs asdf • chruby • gemsets vs bundler groups • multiple Ruby versionsModule 2: Deployment patternsCapistrano vs Kamal vs Docker + Compose • zero-downtime deploy • blue-green / canary basicsModule 3: Containerization & Orchestration introDockerfile best practices • multi-stage builds • simple Kubernetes manifests for Ruby appsModule 4: Observability stackPrometheus + Grafana • OpenTelemetry basics • structured logging (lograge, semantic_logger) • error tracking (Sentry, Rollbar)Module 5: Security in Ruby appsBrakeman, bundler-audit, secure_headers • OWASP top 10 in Ruby context • secrets management (dotenv vs Vault)Module 6: CI/CD pipelinesGitHub Actions / GitLab CI examples • parallel testing • auto-deploy on merge • gem cachingModule 7: Legacy code handlingStrangler fig pattern strategies • characterization tests • golden master testing • gradual refactoringModule 8: Scaling & resilience patternsCircuit breaker, retry, rate limiting • sidekiq pro features • database connection pooling tuningModule 9: Final capstone exerciseFull production setup: Docker + CI + observability + secure config + deploy script for a simple Ruby service Who this course is forSuitable if you: already have experience deploying Ruby apps but want modern, resilient practices face downtime, slow deploys, or production complexities plan to work in teams where code lives for years, not months 🚀 Not suitable if you: have not yet written production code or dealt with real servers are looking only for "how to run on Heroku" without depth What you will studyHow to set up stable environments and tools for multiple Ruby versionsDifferent deployment strategies with minimal downtimeHow to build observability without expensive SaaS (or with them)How to detect and fix security issues in Ruby codeHow to handle legacy code without full rewrite About the authorDeveloper with over 8 years of Ruby experience. Worked on high-load systems where uptime, observability, and fast recovery were critical.
