Abstract

The present disclosure is directed to preserving running sessions during a side-by-side upgrade of system resources. Example aspects include deploying a first version and a second version of a system resource to a server within a network, the first version and the second version of the system resource both maintained within the system network and accessible via a version agnostic Application Programming Interface. Example aspects can receive, at a front-end server, a request for interaction with the system resource from a first client system, the request from the first client system including a header including version-identifying information. The systems and methods can determine, at a session version redirector, that the client system should be provided the first version and not the second version based on the version-identifying information in the header.

Claims21

Dependent claims

A system for preserving running sessions during side-by-side upgrade, the system comprising:

one or more processors;
a memory coupled to the one or more processors, the memory storing a session preservation application comprising computer-executable instructions that, when executed by the one or more processors, causes the system to:
deploy a first version and a second version of a system resource to a server within a network, wherein the first version and the second version of the system resource are both maintained within the system network and accessible via a version agnostic Application Programming Interface, the second version of the system resource being updated relative to the first version;
receive, at a front-end server, a request for interaction with the system resource from a first client system, the request from the first client system including a header including version-identifying information;
determine, at a session version redirector, that the client system should be provided the first version of the system resource and not the second version of the system resource based on the version-identifying information in the header;
and
in response to the request from the first client system, provide the first version of the system resource to the first client system.

4 more elements

A computer-readable storage medium encoded with computer-executable instructions that, when executed by a computer, cause the computer to:

receive, at a front-end server, a first request from a client system for interaction with a system resource hosted at a server within a server network;
provide a first version of the system resource to the client system;
deploy a second version of the system resource to a server within the system network, such that the first version and the second version of the system resource are both maintained within the system network;
receive a second request for interaction with the system resource from the client system;
determine, at a session version redirector, that the client system has an existing session associated with the first version of the system resource;
and
in response to the second request, provide the first version of the system resource to the client system.
