Hi Team
We have a requirement to for a Software based NLB to Load Balance an enterprise application. Following are the Capacity and Features of NLB required. Please confirm, does HA Proxy supports the below capacity and features ?. let us know the licensing model and Support structure. Capacity : - Requests per Second = 5000 RPS - Concurrent Connections = 5000 Concurrent Sessions. - Throughput = 40 Mbps Features : 1. *Routing Profile * Routing profile can be TCP based (layer 4) or HTTP based (layer 7). 1. *Load Balancing Method* All load balancing methods are supported. It is recommended to use Least Connections or Round Robin load balancing methods, for better distribution between Application servers. 1. *Session persistence (stickiness)* The LB must be configured with session persistence to enable a session connection with the same application server instance. Configure session persistence in all levels of load balancing (for example, if there is a global load balancer in front of a few local load balancers). To achieve session persistence, configure the LB with one of the following persistence profiles: - HTTP Cookie - Client IP (Source address) 1. *Health monitoring* An important property of an LB is the ability to perform health monitoring checks (heartbeats) on each Application server. By using health monitors, the LB verifies the server response or checks for any network problems that can prevent a client from reaching a server. By doing so, the LB can place the server in or out of service and can make reliable load-balancing and high availability decisions. A common and recommended health monitor is *HTTP GET Request.* 1. *Idle (execution) timeout* Setting the execution timeout controls termination of idle connections. Configure an execution timeout of at least 4 hours. 1. *HTTPS Configuration* The load balancer supports several HTTPS configuration methods. These include: - SSL bridging - SSL offload - SSL pass-through SSL bridging and SSL offload are supported in HTTP based routing (layer 7), and require deploying TLS certificate on the LB. SSL pass-through is supported in TCP based routing (layer 4), and does not require deploying a certificate on the LB. Regards Mohammed Anees +91 9944170656
