How We Scaled a .NET Startup
- 1. You Too Can Be a Radio Host or How We Scaled a .NET Startup and Had Fun Doing it! Aleksandr Yampolskiy and Rob Blackin
- 3. Previously Director of Development at IDT in charge of systems for global businesses in 9 diff countries
- 4. CIO of VoiceNet subsidiary of Destia.
- 7. 10 of them in Tech
- 8. HQ in New York, NY

- 12. The Cinchcast Platform Confidential © 2011 Cinchcast - All Rights Reserved 5
- 13. DEMO TIME - LIVE Confidential © 2011 Cinchcast - All Rights Reserved 6
- 14. Our Approach “Be brief, be bright, be gone” Don’t go chasing hot technologies of the day. Instead ‘mitigate your top problems’ Achieve “essential”, then worry about “excellent”. Be a “how team” instead of a “no team”. Build security into the software development lifecycle. Love And Other Drugs
- 15. Current Technology Stack .NET 3.5 C# Jenkins + Nunit Sauce On Demand - Selenium Gomez + NewRelic for monitoring JQuery ASP.NET and MVC 3 IIS 6 SQL SERVER 2005 Windows Server 2003 and 2008 Red 5 Asterisk, Pactolus AiCache Aptimize
- 16. Development Environment Visual Studio 2010 StyleCop / Resharper experimentation. Scrum methodology for large features + adopting Kanban for various bug fixes JIRA for project management + Greenhopper Svn, Jenkins
- 17. Metrics Not using metrics for your dev process is like landing a plane without any instruments in a storm. Code coverage Site throughput Number of critical security bugs Time to fix Blocker/Critical/Major JIRA issues. Percentage of developers using your site. Etc.
- 18. What Do Metrics Tell Us?
- 19. Architecture
- 25. Evolution Summary 2008 – Multiple web servers via Coyote LB and Scaleout for session state 2009 – Read Only databases through replication and aptimize for combining JS, CSS and Images on the fly. 2010 - aiCache for caching html, second farm on amazon for specific traffic, specializtion of web and database servers. 2011 – Contendo cdn, services framework, retired aptimize due to Continuous Integration process, Service broker queuing.
- 29. Can be used either as DLL imports or through RESTful calls on the network.BlogTalkRadio Cinch.FM Cinchcast
- 30. Services Based on Martin framework (https://github.com/thegrubbsian/Martin) Lightweight .NET framework mapping URLs to actions. Modified framework to reflect interfaces and automatically expose all their methods.
- 32. Not all data is relational, so database isn’t always a good medium.
- 33. Logging is key to detecting problems.
- 35. Elastic Search
- 36. Caching “Donut caching” : caches most of the page except a few dynamic regions. .Net caching via Fixed Expiration myCache.Insert("LiveChatRooms", liveRooms, myDependency, DateTime.UtcNow.AddMinutes(2), Cache.NoSlidingExpiration); .Net caching via Sql Dependency Expiration SqlCacheDependency myHDDependency = new SqlCacheDependency(DBName, "Genres"); myCache.Insert(DictionaryOfGenreEntityByID, myDictionary, myHDDependency); Data Caching via Scaleout return DCacheSoss.GetObjectFromNamedCache(CacheName, UniqueKeyName); CDN caching of JS, CSS and Images via Contendo and Limelight HTML Caching via CDN – Contendo, Limelight, aiCache
- 37. Cool Tech Projects On the Horizon Personalization of radio shows based on customer’s preferences. Build out of SOA Cinchcast platform from Python, .NET, Java components communicating as RESTFUL JSON-based services Moving real-time search to ElasticSearch (right now just for RSS/bots) Improving our caching layer performance (too many hit misses) A/B testing framework
- 39. Don’t chase hot technologies (e.g. MemCached mania). Sometimes reinventing the wheel is good.
- 40. REST+JSON > SOAP+XML
- 42. Sys Admin
- 43. Tech Lead
- 44. If you are good we’ll find a role for you : jobs@cinchcast.comWell-funded profitable startup used by millions. Patent-pending radio tech utilized in a new way. Medical/dental/etc. benefits. Great office space in mid-town right near subway. Flexible hours. Top-notch compensation + stock options.
