Derek Collison gave a presentation on Cloud Foundry and why Ruby was chosen as the programming language. Cloud Foundry is an open platform as a service (PaaS) that allows applications to be deployed and scaled across clouds. It uses Ruby due to its expressiveness, productivity, and ability to implement asynchronous patterns required for a distributed system. However, Ruby's performance and packaging could be improved. While Ruby was a good choice, its future depends on how well it can power mobile, data-centric and distributed applications.
RubyWorld 2011
- 1. RubyWorld 2011 Cloud Foundry Why Ruby, and will it last? Derek Collison Sept 5, 2011
- 2. Agenda ‣ What is Cloud Foundry? ‣ Why Ruby? ‣ The Business of Cloud Foundry ‣ Challenges and Ruby’s future
- 4. The Open Platform as a Service
- 6. Or more specifically, aPaaS?
- 7. aPaaS ‣ Application Platform as a Service ‣ Applications and Services ‣ Not VMs, Memory, Storage, Networks, CPU
- 9. OpenPaaS ‣ Multi-Language ‣ Multi-Framework ‣ Multi-Services ‣ Multi-Cloud, Multi-IaaS ‣ Hybrid - Public or Private or Both ‣ OpenSource
- 10. OpenPaaS ‣ Multi-Language ‣ Ruby, Java, Scala, Node.js, Erlang, Python, PHP.. ‣ Multi-Framework ‣ Rails, Sinatra, Spring, Grails, Express, Lift, MochiWeb ‣ Multi-Services ‣ MySQL, Postgres, MongoDB, Redis, RabbitMQ ‣ Multi-Cloud, Multi-IaaS ‣ vSphere, MicroCloud, OpenStack, AWS, Eucalyptus
- 11. The Open PaaS Ap .js ce p rfa Private lic te at Data Services Clouds In io n er Se vid r vic Public o e Pr Clouds In Messaging Services ud te rfa o Cl ce Micro Clouds Other Services
- 12. What was our Goal? ‣ Raise the unit of currency to be the application and its associated services, not the infrastructure ‣ Best of breed delivery platform for all modern applications and frameworks ‣ Favor Choice and Openness ‣ Simplicity and Speed
- 13. How was it Built? ‣ Kernel (CloudFoundry OSS) ‣ Core PaaS System ‣ Kernel and Orchestrator Shells ‣ Layered on top of IaaS ‣ Orchestrator ‣ Creation, management and orchestration of IaaS
- 14. High Level Clients (VMC, STS, Browser) CF Kernel Orchestrator / IaaS Hardware - CPU/Memory/Disk/Network
- 15. Basic Premises ‣ Fail Fast ‣ Self Healing ‣ Horizontally Scalable Components ‣ Distributed State, No Single Point of Failure ‣ Should be as simple as possible
- 16. Basic Patterns ‣ Event-Driven ‣ Asynchronous ‣ Non-blocking ‣ Independent, Idempotent ‣ Message Passing ‣ Eventually Consistent
- 17. Logical View Browser VMC client STS plugin (user app access) Routers CloudControllers App App HealthManager Services DEA Pool Messaging
- 18. All built with Ruby 1.9!
- 19. But why Ruby?
- 20. Why Ruby? ‣ Amazingly Expressive Language ‣ Allows great productivity and rapid iteration ‣ Utilized EventMachine for Async Patterns ‣ Ruby 1.9 Fibers ‣ Language performance is not always key ‣ All components are independent
- 21. Kernel and Orchestrator ‣ Both built using Ruby 1.9 ‣ Kernel does have some performance issues ‣ Orchestrator, Chef, Puppet ‣ Ruby is a great language for cloud management ‣ CF Orchestrator built with Ruby as well
- 22. How do we make Money?
- 23. The Business ‣ Charge for CloudFoundry.com and Services ‣ Enable the private enterprise PaaS Cloud ‣ Hybrid clouds, combining service + software
- 24. The key is the private cloud..
- 26. Many customers don’t want to be thrown into the deep end of the pool!
- 27. Same Patterns Everytime ‣ Customers get a CF.com account and try it ‣ Download source code and try to build ‣ Try to setup a multi-node installation ‣ Request information on hybrid capabilities
- 28. Same Patterns Everytime ‣ Customers get a CF.com account and try it ‣ Download source code and try to build ‣ Try to setup a multi-node installation ‣ Request information on hybrid capabilities
- 29. This can be hard..
- 30. Answer:MicroCloud Full single instance CF as a downloadable VM Available now
- 31. Micro Cloud Foundry Cloud Foundry on a USB Available at RubyWorld
- 32. Same Patterns Everytime ‣ Customers get a CF.com account and try it ‣ Download source code and try to build ‣ Try to setup a multi-node installation ‣ Request information on hybrid capabilities
- 33. This can be even harder..
- 34. Answer: Project Bento Fully supported private cloud version of CF Available 2012
- 35. Cloud Foundry EcoSystem VMware 3rd party OSS code OSS code VMware 3rd party proprietary proprietary code code CloudFoundry.org CloudFoundry.com Bento Micro Cloud Foundry
- 36. Demo
- 38. Ruby VM, Gil, GC issues
- 39. EventMachine Problems (1.9, IO skew)
- 40. Evented IO ‣ Event-driven programming ‣ Fundamental shift in thinking, e.g. Node.js ‣ Does this require deeper language integration for Ruby? ‣ Does Ruby need a formal Reactor Pattern?
- 42. Gem vs VM Choice compatibility (MRI/Yarv, JRuby, RBX)
- 43. Did we make the right decision?
- 44. Did we make the right decision? YES!
- 45. But...
- 46. What does Ruby want to be when it grows up?
- 47. What is Ruby? ‣ Great scripting language! ‣ Cloud Management and Tools ‣ Modern Application Language! ‣ Mobile, Data-Centric, Web ‣ Distributed/Cloud Systems Language?
- 48. What would need to Change?
- 49. Summary
- 50. Summary ‣ Ruby can power large distributed systems ‣ Ruby can power your business ‣ What does Ruby want to be? ‣ What needs to evolve and improve?
- 51. Questions?
