Amazon’s Elastic Load Balancer (ELB) is not designed to handle sudden spikes. Customers need to request AWS to pre-warm the ELB to get it ready to handle the expected load. This requires a subscription to AWS support. GCE’s Load Balancer doesn’t require pre-warming. It scales instantly to support spiky traffic. Compute Engine Load Balancing hits 1 million+ requests per second with no pre-warming.
