First, the cluster type:1. Load Balancer Cluster (LB cluster--load balancing):Considering the increase of server capacity is the main technology for scalability expansion.Consider an extension when the following scenario occurs for concurrent requests:1200 request: 1s1500 Request: 2s1800 Request: 10sExtension Type:Scale up: upward, requiring more powerful servers, the downside is that the upper limit is limited and its cost-effective.Scale out: More than n hosts are required.A, LB software solut
