VMware NSX Edge (load balancer) is a solution that provides routing, Firewall, NAT, DHCP, Site to Site VPN, SSL VPN-Plus, Load Balancing, High Availability, syslog for the virtual data center. Physically implemented as a virtual machine, connected to the networks of a virtual data center and to external networks (Internet).

Why do i need Load balancer?

Load balancer is located between the client and the server farm that receives incoming network and application traffic and distributes traffic to multiple servers using different methods. By balancing application requests across multiple servers, the load balancer reduces the load on a single server and does not allow one application server to become a single point of failure, thereby improving overall application availability and responsiveness.
The volumes of traffic are growing, and applications are becoming more complex. Load balancers provide the foundation for creating flexible networks that meet growing demands, increasing productivity and security for many types of traffic and services, including applications.
