Interface for secure cloud metadata retrieval

A method for metadata interfacing, comprising:

• establishing, by an application server, a proxy service component associated with a metadata source associated with a first version of a metadata service and having a first type of metadata requests;
• configuring, by the application server, a packet filtering component associated with redirection of metadata service traffic directed to the metadata service associated with a second type of a second version of the metadata service;
• receiving, by the application server and from a request source, a first metadata request directed to an endpoint associated with the first version of the metadata service;
• determining, by the application server and using the packet filtering component, that the first metadata request is associated with the second type of the second version of the metadata service;
• passing, by the application server, the first metadata request from the packet filtering component to the proxy service component;
• authorizing, by the application server, the first metadata request for fulfillment by the proxy service component;
• generating, by the application server and using the proxy service component, a second metadata request associated with the first type of the first version of the metadata service based on authorizing the first metadata request for fulfillment;
• transmitting, by the application server, the second metadata request to the metadata service;
• receiving, by the application server, a metadata response as a response to the second metadata request;
• and
• transmitting, by the application server, information identifying a content of the metadata response to the request source as a response to the first metadata request.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a system, cause the system to:
• establish a proxy service associated with a proxy user;
• configure a packet filter rule associated with redirection of metadata service traffic, associated with a metadata service, originating from a source other than the proxy service;
• receive a metadata request for metadata from the metadata service;
• evaluate the metadata request to determine whether to authorize the metadata request;
• extract request information associated with identifying the metadata that is responsive to the metadata request based on authorizing the metadata request;
• obtain the metadata that is responsive to the metadata request;
• and
• transmit a metadata response message conveying the metadata that is responsive to the metadata request.
