Amazon SimpleDB is a hosted database service that allows developers to store and query structured data via web services requests without needing to worry about data modeling, index maintenance, or performance tuning. It is a flexible, scalable, and inexpensive key-value store that automatically indexes data and enables real-time lookups and simple queries without complexity. Netflix migrated parts of its database from Oracle to Amazon SimpleDB to take advantage of its high availability, flexibility, and cost effectiveness compared to running its own data centers.

- 28. CASE STUDY( contd...) Traditional relational database technologies were not built to accommodate large volumes of data, neither from a cost- effective perspective nor regarding the needs for continuous availability and flexibility. In 2010, Netflix began moving its data to Amazon Web Services (AWS) to offer subscribers more flexibility across devices.
- 29. CASE STUDY( contd...) Netflix decided to migrate from Cassandra to DataStax Enterprise for its enterprise-level security and production. About 95% of Netflix’s non-program data is stored in DataStax Enterprise. Includes customer account information, movie ratings, bookmarks and logs, and viewing history services.
- 30. Case STUDY( contd...) Performed immense amounts of customer viewing and log data to improve subscribers’ searching and streaming experiences. Multiple geographically dispersed data centers and processing capacity. Netflix decided to migrate its applications to Amazon’s AWS cloud. Netflix migrated core parts of its database from Oracle to Amazon’s SimpleDB data store. Added customer value rather than nationwide data centers.
