Our clients are using Fortinet FortiADC primarily for load balancing, which serves as the application server load balancer. We have worked with one or two cases of Fortinet FortiADC. For application load balancer solutions, we prefer either A10, which is a leader product present in Gartner leader and Forrester leader, or Radware. We worked with a customer who was in the Fortinet environment, so we suggested Fortinet FortiADC, which helps integrate with FortiWeb, a WAF solution.
For integration purposes, we implemented Fortinet FortiADC, and they had around four applications and 20 servers. We were able to do the load balancing based on the round robin method in that ADC, which was the use case objective of having the ADC solution. It was placed behind the WAF solution, so SSL offloading and transitions were taken care of in the SLB part, specifically Fortinet FortiADC.
Regarding SSL offloading, we had the same use case since they need the certificate for external communications, but for internal communications, they had a separate certificate. We just offloaded the SSL in WAF, and we do the SSL transition in the Fortinet FortiADC part.
When speaking about load balancing, this refers to GSLB, which stands for Global Server Load Balancing. The use case was to balance the loads in a hospital environment with one main application and other side applications supporting doctors, the database for their medical equipment, and related systems. The main application was an online consulting application. The task of Fortinet FortiADC was to load balance the number of hits based on the round robin algorithm and manage the balances between the four or five servers allocated to the application.
