Scalable proxy clusters

A computer program product for synchronizing data states between proxy nodes within a networked cluster of proxy nodes, comprising a non-transitory computer usable medium having a computer readable program code embodied therein, the computer readable program code comprising instructions executable to:

• detect a synchronization event at a first proxy node within the networked cluster of proxy nodes;
• synchronize, at the first proxy node, one or more data states of the first proxy node with corresponding one or more data states of a second proxy node within the networked cluster of proxy nodes, the one or more data states of the first proxy node and the corresponding one or more data states of the second proxy node including information descriptive of a set of Application Programming Interfaces (APIs) hosted on a set of servers;
• reconfigure, in response to a change to an API from the set of APIs and hosted on a server from the set of servers, the one or more data states of the first proxy node to reflect the change to the API;
• communicate, from the first proxy node, the one or more data states of the first proxy node after the reconfiguring to the remaining proxy nodes in the networked cluster of proxy nodes such that each proxy node from the remaining proxy nodes, in response to receiving the one or more data states of the first proxy node, synchronizes one or more data states of that proxy node with the one or more data states of the first proxy node;
• and
• transmit an API request received from a client device to a server (1) from the set of servers and (2) identified based on a routing policy and the information descriptive of the set of APIs.

An apparatus, comprising:

• a memory;
• and
• a processor associated with a proxy node from a plurality of proxy nodes in a cluster of proxy nodes, the processor operatively coupled to the memory and configured to:
• synchronize, in response to a synchronization event, a data state of the proxy node with a data state of at least one proxy node other than the proxy node and from the plurality of proxy nodes, the data state of the proxy node and the data state of the at least one proxy node other than the proxy node including information descriptive of a set of Application Programming Interfaces (APIs) hosted on a set of servers;
• reconfigure, in response to a change to an API from the set of APIs and hosted on a server from the set of servers, the data state of the proxy node to reflect the change to the API;
• communicate the data state of the proxy node that reflects the change to the API to the remaining proxy nodes from the plurality of proxy nodes such that each proxy node from the remaining proxy nodes, in response to receiving the data state of the first proxy node, synchronizes a data state of that proxy node with the data state of the proxy node;
• extract, from an API request received from a client device, information descriptive of an API associated with the API request;
• and
• identify a server from the set of servers to transmit the API request to based on (i) the information descriptive of the set of APIs, (ii) the information descriptive of the API associated with the API request, and (iii) a routing policy.
