How does WSO2 ELB pull information from a Cloud Service Cluster (IaaS) such as OpenStack in order to perform auto-scaling? Does WSO2 ELB make use of any Cloud Service Cluster internally? If it does, what IaaS vendor is implemented out-of-the-box?
Does WSO2 even pull any information at all? Does it just require the host machines to be in a cluster in order for the worker/manager or auto-scaling algorithm to work?
Thanks for explaining.
