Abstract: It’s an interesting paradigm where hybrid systems using Sql and NoSql databases are more a necessity than just good to have. With all these options around us Couch Db, Cassandra, Raven Db, Mongo Db, HBase et al. it is easy to get confused. Come and learn the strengths and weaknesses of the major NoSql databases. As a developer you will learn how to create features that may not exist in some of these databases in your app. You will see feature by feature comparison and performance in different business cases. You will understand what makes the most sense for your business case. All the examples will be based on Windows Azure and yes, it’s not a surprise that all of them run great on Windows Azure and it’s very easy to use them.

Abstract: What is Dependency Injection? The answers to the question seem to cause more confusion than help. We’ll take a look at what Dependency Injection (DI) is, when we should use it, and what design patterns we can use to help us implement it. Benefits range from extensibility to late binding to testability. We can implement DI with or without a container (such as Unity, Ninject, or StructureMap), but we’ll see how a container can do a lot of the work for us.

Abstract: Reactive extensions have long been used for controlling UI events and interactions [1]. Rx is also great for backend and middleware interactions. As illustrated by Netflix’s porting [2] Rx library to Java in their recently released port RxJava [3]. Rx is a great abstraction for handling concurrency, client side or server side. In my talk I would give a short overview of Rx and its capabilities. I will show a simple implementation of an In Memory Bus with Rx. I will show how Rx can help with common backend operations, like logging and testing. I will also show how an abstraction of Windows Service Bus [4] with Rx, this will simplify the api and use case scenarios.
