💻 How large companies build architecture: solutions, technologies, approaches

📦 Version control and API management

They use Garage Extension — an extension to the monolith (Rails), configured separately via a client.
Required: Rails / Sinatra, gRPC / JSON API, CI/CD (e.g., GitHub Actions, CircleCI)

🔗 Microservice communication

Challenge: requests between many services → complexity, latency, fault tolerance.
Solution: GenExpediter — a Ruby equivalent of Netflix Hystrix.

Required: concurrent-ruby, Redis / Kafka / RabbitMQ for queues, Sidekiq / Resque, Circuit breaker + fallback logic, Monitoring: Prometheus + Grafana

🏗 Lego-style architecture approach
Rails is minimalist but flexible. Want a monolith — keep it. Want microservices — add them.

Options: Dry-rb — clean architecture, Hanami — for stricter structure, Event Sourcing via RailsEventStore, gRPC / JSON-RPC for inter-service communication

💻 Exactly 21 years ago, DHH introduced the world to the first version of Rails — v0.5.0 — with the words: "this piece will grow in public."

He wasn’t wrong.

Since then, Ruby on Rails has become the foundation for thousands of companies around the world, grown with the support of countless developers, and stayed true to its core principles: simplicity, elegance, and productivity.

Rails 0.5.0 marked the end of vaporware — and the beginning of a new era in web development.

Original announcement from July 24, 2004:

Want to build iOS and Android apps without leaving Rails?

At RailsConf 2025, Joe Masilotti showed how Hotwire Native lets you create native mobile apps using just HTML, CSS, and Rails.

One codebase — three platforms: Web, iOS, Android

Instant updates across all platforms

Only 31% of Rails developers use Stimulus, while the majority believes that Rails API + SPA architecture is “necessary.”
Inertia.js allows to build modern JS components without the SPA complexity:
