A proxy server acts as an intermediary between a database client and a database server. The proxy server is configured with a set of user-defined rules. When a request is received from the database client, the proxy server may apply rules that modify, route, reject, log, or pass the request to the database server. Individual rules may be based on attributes of the client computer system, database server, or the request itself. In one embodiment, a rule may be used to translate a request from a format provided by the client into a format preferred by a destination database. In one embodiment, a rule may route a particular request to one of a number of databases based on the nature of the request.

Database proxy

A database proxy server provides a web service interface such as a representational state transfer ('REST') interface to a relational database. The proxy server maps a request submitted via the web service interface to a database interface. In some examples, the web service interface is a stateless REST interface that maps particular SQL statements or subroutines to a request submitted via a particular URL. A web client is able to pass parameters with a request using either URL encoding (the GET method) or within the body of the request (the POST method). The proxy server generates one or more database commands that correspond to the request. The database commands are submitted to the relational database, and the relational database performs the database commands to fulfil the request.

Database rest API

A proxy server acts as an intermediary between a database client and a database server. The proxy server establishes and maintains a set of logical connections to the database server. The proxy server receives a request from the database client, and generates a set of database commands that, when performed by the database server, are capable of fulfilling the request. The proxy server selects a particular logical connection from the set of logical connections based at least in part on a characteristic of the request, and submits the set of database commands to the database server via the selected particular logical connection. In various examples, the particular logical connection is selected so that various performance, efficiency, and security objectives are achieved.

Database proxy connection management

A proxy server receives requests from a client computer system and generates corresponding sets of database commands that are capable of fulfilling the requests when submitted to a database server. The proxy server may repeat processing associated with a particular request more than once under different operational conditions in order to improve future performance. In some examples, the proxy server submits a particular database command sequence to the database server using various operational parameters, and measures the performance of each submission to identify a particular set of operational parameters to be applied to the database server with future submissions. In another example, the proxy server determines a number of alternative command sequences that fulfill a particular request, and measures the performance of each of the alternative command sequences to determine how command sequences are generated for future requests.

Database command replay

Resources hosted in different virtualization platforms may be managed across the different virtualization platform. Requests to perform types of actions with respect to a resource hosted in a type of virtualization platform may be received. Mapping information between types of actions and actions available via interfaces for different types of virtualization platforms may be evaluated to select actions for an interface of the type of virtualization platform that hosts the resource. The selected actions may then be performed via the interface to perform the action with regard to the resource.
