Relational Database Service (Amazon RDS) Amazon RDS gives you online access to the capabilities of a MySQL, Oracle, Microsoft SQL Server, PostgreSQL, or Amazon Aurora relational database management system. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call. Database Instances using Amazon RDS's MySQL, Oracle, SQL Server, and PostgreSQL engines can be provisioned with General Purpose (SSD) Storage, Provisioned IOPS (SSD) Storage, or Magnetic Storage.
In addition, Amazon RDS makes it easy to use replication to enhance availability and reliability for production workloads. SimpleDB. Amazon SimpleDB is a highly available NoSQL data store that offloads the work of database administration. Developers simply store and query data items via web services requests and Amazon SimpleDB does the rest. Unbound by the strict requirements of a relational database, Amazon SimpleDB is optimized to provide high availability and flexibility, with little or no administrative burden. Behind the scenes, Amazon SimpleDB creates and manages multiple geographically distributed replicas of your data automatically to enable high availability and data durability. The service charges you only for the resources actually consumed in storing your data and serving your requests.
The service allows you to focus fully on value-added application development, rather than arduous and time-consuming database administration. Amazon SimpleDB automatically creates multiple geographically distributed copies of each data item you store. Application examples include: Hadoop | Hadoop Download | Cloudera Hadoop | Cloudera. Cloud-hosted MongoDB. MongoHQ - The cloud-based hosted database solution for MongoDB. Couchbase | The First Comprehensive NoSQL Database Family.
