From PHP monolith to polyglot microservices
- 1. From PHP Monolith to Polyglot Microservices Kazki Matz @ CareerLink Vietnam
- 2. About me • Kazuki MATSUMOTO (Kazki Matz) • Rubyist (Since 2009) • Been living in Vietnam (Since 2012) • CTO at CareerLink Vietnam (Since 2012)
- 4. Our architecture (~ 2015) • PHP Monolith built with Symfony2 Symfony2 Monolith (mod_php) LB (Nginx) MySQL mongoDB ElasXcsearch
- 5. Microservices Architecture Building applicaXon as a suite of small services • Each service has it’s own codebase • Each service runs under dedicated process • Each service can be wriZen in different languages • Each service has it’s own datastore • Each service has it’s own deployment strategy

- 7. • Inter-‐process communicaXon overhead – SerializaXon, Network RTT • New middlewares – Load balancing / API discovery • More management costs – Monitoring & Error NoXficaXons – Deployment Infrastructure – Performance Profiling Cost of Microservices
- 8. • Inter-‐process communicaXon overhead – SerializaXon, Network RTT • New middlewares – Load balancing / API discovery / Profiling • More management costs – Monitoring & Error NoXficaXons – Deployment Infrastructure – Performance Profiling Cost of Microservices
- 9. • Inter-‐process communicaXon overhead – SerializaXon, Network RTT • New middlewares – Load balancing / API discovery • More management costs – Monitoring & Error NoXficaXons – Deployment Infrastructure – Performance Profiling Cost of Microservices
- 10. New middlewares • Load balancing • API discovery / rouXng service • RPC request profiling
- 12. RabbitMQ RPC: Pros • No need of load balancing • No need of API discovery service • Synchronous RPC / Asynchronous Messaging • Nice built-‐in web UI
- 14. RabbitMQ RPC: Cons • Not scalable • No request logging/profiling
- 15. • Inter-‐process communicaXon overhead – SerializaXon, Network RTT • New middlewares – Load balancing / API discovery • More management costs – Monitoring & Error NoXficaXons – Deployment Infrastructure – Performance Profiling Cost of Microservices
- 16. Error NoXficaXons
- 17. Deployment
- 18. Cost of Microservices • Inter-‐process communicaXon overhead – SerializaXon, Network roundtrip • New middlewares – API gateway • More management costs – Monitoring & Error NoXficaXons – Deployment Infrastructure – Performance Profiling
