Today, we published a second article that expands on the original XI50/XC10 integration article by demonstrating how to load balance HTTP REST requests from the XI50 across a collective of XC10 appliances. In a typical production environment, to handle high volumes of HTTP traffic, a load balancer is used to evenly distribute the HTTP traffic across a group of servers. The same principle can be applied to a collective of XC10 appliances to evenly distribute HTTP REST requests across the collective. It is important to understand that the REST gateway on each appliance acts as a client to the data grid. Therefore, it contains a table of partition locations so it can quickly access the specific data in the grid, regardless of which appliance has the data. By load balancing these HTTP REST requests, you are balancing the HTTP processing load across the collective of XC10 appliances. The XI50 has built in load balancing capability. Part 2 shows you how to configure a collective of XC10s, configure a load balancer and define a load balancer group on the XI50. The load balancer group contains the hostnames of the XC10 appliances in the collective.
