This year, a small team of developers delivered a ASP.NET MVC app, with a Neo4j backed, all running in Azure. This isn't in POC; it's a production system. Also, unlike most graph DB talks, it's not a social network! In this session you'll hear the stories of: - what our project is, why we chose a graph db, how we modelled it to start with and how our model was wrong, - how we deploy neo4j in Azure, - how we diagnosed and fixed a performance problem that spanned the CLR, the JVM and Azure, - how we built our own Neo4j client for .NET, complete with a fluent, interface and internal logic to serialize .NET - expressions into Groovy comparisons (It was only slightly scary.)
