Exemplary computer system architectures and methods are described. In some embodiments, a computer network comprises a computing engine including a plurality of compute nodes and a load balancer coupled to the computing engine and including a processor and a memory module. The memory module comprises logic instructions which, when executed by the processor, configure the processor to receive a connection request from a client computing device for computing services provided by one of the compute nodes, obtain, from the connection request, a session identifier associated with the request, and store the session identifier in a memory coupled to the load balancer.
