The Production-Grade Ruby Microservices Stack (2026)
March 2, 2026
Microservices don’t fail because of Ruby.
They fail because of architecture.
Most “microservices” I see in Ruby are:
• HTTP chains tightly coupled together
• Shared databases behind the scenes
• No tracing
• No event replay
• No contract validation
That’s not distributed architecture.
That’s a distributed monolith.
