Abstract

In one aspect, the present disclosure relates to a method comprising: receiving, at a client device, information from a node manager about a plurality of nodes in a computer cluster, the information comprising a network address associated each of the plurality of nodes and sending, by the client device, a request to a load balancer to access a first node from the plurality of nodes, the request comprising a first URL including an encoded representation of the network address associated with the first node. The load balancer is configured to determine the request should be routed to a first network address based on decoding the URL, the first network address associated with a first node from the plurality of nodes and forward the request to the first node in response to the determining.

First claim

The invention claimed is:

1. A method comprising:
receiving, at a client device, information from a node manager about a plurality of nodes in a computer cluster, the information comprising a network address associated each of the plurality of nodes; and
sending, by the client device, a request to a load balancer to access a first node from the plurality of nodes, the request comprising a first URL including an encoded representation of the network address associated with the first node, wherein the load balancer is configured to:
determine the request should be routed to a first network address based on decoding the URL, the first network address associated with a first node from the plurality of nodes; and
forward the request to the first node in response to the determining.

2. The method of claim 1 wherein the first URL comprises an encoded representation of an Internet Protocol (IP) address associated with the first node.

3. The method of claim 2 wherein the first URL comprises a hash of the IP address associated with the first node.

4. The method of claim 1 where the first URL comprises an encoded representation of the network address associated with the first node within the subdomain portion of the first URL.

5. The method of claim 1 where the first URL comprises an encoded representation of the network address associated with the first node within the path portion of the first URL.

6. The method of claim 1 comprising:
receiving, by the client device, a response from the load balancer, the response comprising a response received from the first node.

7. The method of claim 1 wherein the node manager is a cluster node manager.

8. The method of claim 1 wherein the load balancer is a cluster load balancer.

9. A system comprising:
a processor; and
a non-volatile memory storing computer program code that when executed on the processor causes the processor to execute a process operable to:
receive, from a node manager, information about a plurality of nodes in a computer cluster, the information comprising a network address associated each of the plurality of nodes; and
send, to a load balancer, a request to access a first node from the plurality of nodes, the request comprising a first URL including an encoded representation of the network address associated with the first node, wherein the load balancer is configured to:
determine the request should be routed to a first network address based on decoding the URL, the first network address associated with a first node from the plurality of nodes; and
forward the request to the first node in response to the determining.
