using Spring and MongoDB on Cloud Foundry
The document provides an overview of using Spring and MongoDB with Cloud Foundry, highlighting key features and data access challenges. It discusses Spring Framework's built-in support for various data access methods, including NoSQL and document stores, and includes practical examples of using MongoTemplate and custom repositories for MongoDB. Additionally, the document details the integration of these technologies within the Cloud Foundry environment and offers resources for further exploration.

Editor's Notes
- #2 \n
- #3 Hello, thank you or having me. Im pleased to have the opportunity to introduce you today to Spring and the SpringSource Tool Suite \n\nMy anem is Josh Long. I serve as the developer advocate for the Spring framework. I’ve used it in earnest and advocated it for many years now. i’m an author on 3 books on the technology, as well as a comitter to many of the Spring projects. Additionally, I take community activism very seriously and do my best to participate in the community. Sometimes this means answering question on Twitter, or in the forums, or helping contribute to the InfoQ.com and Artima.com communities\n

- #7 Oracle RAC clustering is very expensive. $70K/CPU according to list. Even at ½ the cost, it’s still really expensive to build out a horizontal data access grid. \n
- #8 The amount of log data amassed in Facebook’s operations is staggering. Rothschild said Facebook manages more than 25 terabytes of data per day in logging data, which he said was the equivalent of about 1,000 times the volume of mail delivered daily by the U.S. Postal Service.\n\nBASE (basically available, soft state, eventually consistent)\n
