Abstract

A dynamic proxy may be implemented for a database that can establish a connection between the proxy and a database engine to perform a database queries received from a client at the proxy. The proxy may receive a connection request (and later database queries) through a first network endpoint from a client. The proxy can then determine based on the source of the connection request a second network endpoint through which to access the database (e.g., the endpoint of the database engine). Once the proxy establishes a connection with the database engine through the second network endpoint, the proxy can request the performance of queries at the database engine instead of the client.

Claims19

Dependent claims

A system, comprising:

a memory to store program instructions which, if performed by at least one processor, cause the at least one processor to perform a method to at least:
receive, from a client at a proxy, a request to connect to a database received by a first network endpoint;
evaluate, by the proxy, a header of a network packet of the request to determine that a payload of the network packet is to be accessed;
access, by the proxy, data to lookup a second network endpoint through which to access the database based, at least in part, on a source identified for the request and the payload of the network packet;
establish, by the proxy, a connection from which to access the database through the first network endpoint and a database engine through the second network endpoint;
receive one or more database queries from the client at the proxy;
and
send, by the proxy, the one or more database queries to be performed by the database engine through the connection.

5 more elements

A non-transitory, computer-readable storage medium, storing program instructions that when executed by one or more computing devices cause the one or more computing devices to implement:

receiving, from a client, a request to connect to a database received by a first network endpoint;
evaluating a header of a network packet of the request to determine that a payload of the network packet is to be accessed;
identifying a second network endpoint through which to access the database based, at least in part, on a source of the request and the payload of the network packet;
establishing a connection between a proxy from which to access the database through the first network endpoint and a database engine;
and
causing the database engine to perform one or more database queries received from the client via the connection.
