The document discusses the architecture of ExceptionTail.com, which uses MongoDB and RabbitMQ. It begins with how the authors started the project and wanted to use Linux and a NoSQL database. They describe their initial architecture using queuing with RabbitMQ to address load issues. They then discuss other architectures using replication and sharding with SQL Server. The final architecture shown uses MongoDB for the data store and RabbitMQ for queuing of messages to address scalability issues. The document concludes with a demo of MongoDB.
