Glossary

Amazon RDS uses the same locations as Amazon EC2. These locations are composed of Regions and Availability Zones.

The database software and version running on the DB Instance.

For MySQL, this is the optionally supplied name for the initially created database on a DB Instance. For Oracle, this is the Oracle System ID (SID) used for connecting to the database on a DB Instance.

An isolated database environment running in the cloud. A DB Instance can contain multiple user-created databases, and can be accessed using the same tools and applications as a stand-alone database instance. Unlike a stand-alone database instance, an DB Instance cannot be accessed via an interactive login session (e.g. ssh).

Used to specify the CPU and memory capacity of a DB Instance.

Customer supplied identifier for the DB Instance that must be unique for that customer in an AWS region.

A DB Parameter Group is a container for engine parameter values that can be applied to one or more DB Instances.

A DB Security Group is a collection of ingress rules maintained by Amazon RDS. The two types of authorizations are IP ranges and EC2 security groups. IP range ingress authorizations allow access to DB Instances from the Internet. EC2 security group ingress authorizations allow access to DB Instances from EC2 instances.

A backup of a DB Instance at a point chosen by the user.

An AWS standard for compute CPU and memory. One EC2 Compute Unit (ECU) provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.

DNS name of a DB Instance.

Port number used by a DB Instance, see endpoint.

A primary DB Instance that has a synchronous standby replica in a different Availability Zone. The primary DB Instance is synchronously replicated across Availability Zones to the standby replica.

APIs that return a potentially large list of records allow a subset to be viewed by using a MaxRecords and Marker value. The MaxRecords value corresponds to the maximum number of records to return, in the event MaxRecords is not specified a default is used. The Marker identifies the last record returned in the set of records (if the set is larger than MaxRecords).

The maximum number of DB Instances and available storage that can be used by a customer.

A standard (non-Multi-AZ) DB Instance that is deployed in one Availability Zone, without a standby replica in another Availability Zone.
