The use of Network Load Balancing technology enables the availability and scalability of some applications: IIS, firewalls, VPNs, and some key businesses. Each node runs a copy of the application. NLB distributes incoming client requests in multiple hosts in the cluster. You can dynamically add a host, or you can boot all traffic to a specific single host, which is called the default master host. Supports u

the Realserver and LVs are in an intranet.Another mode DR: this mode works at the data link layer, and when ARP is performed, there is only lvsserver response to it. The gateway delivered the request to lvsserver. The lvsserver is then sent to Realserver via the scheduling algorithm, in response to the request. No need to go through Lvsserver Direct response to the client. This greatly increases the rate and reduces the pressure on the lvsserver.Keepalived is the work on the LVS, so-called work

Competition is the product of today's society, so there is competition everywhere in the online world. In the world of Server Load balancer, nginx and LVS are comparable.
