In the UVP article, we discussed the importance of load balancing for implementing a highly available and scalable virtual private network (VPN) solution. Even though you can deploy Microsoft RRAS server as a primary VPN server or secondary server to provide capacity, it does not help with high availability. You need to deploy multiple RRAS servers in at least two sites so that every packet doesn’t take the same path when traveling between two users. In this case, you need another solution such as Azure Load Balancer or third-party network load balancer to implement a highly available and scalable VPN solution. With the explosive growth of cloud services and SaaS applications, service providers are striving to deliver reliable experiences at massive scale. To achieve this objective, service providers are adopting load balancing as one of their preferred options for increasing web performance and availability.

Why and when you need to use load balancer?
A load balancer distributes workloads across multiple servers and applications, enabling you to increase capacity and improve availability, scalability, and performance. It also offers functionality such as HTTPS termination and SSL offloading and WAF attacks protection. Load balancing is commonly used in the following scenarios: High availability: The load balancer redirects traffic to available servers to avoid an outage. Scaling: The load balancer distributes traffic to handle increased demand. Security: The load balancer provides security features such as authentication, SSL offloading, and WAF attacks protection.

What is a load balancer?
Load balancers redirect network traffic to backend servers designated to handle the request. A load balancer can distribute network traffic across multiple servers or hosts in order to increase the capacity of the servers, balance the load across servers, or provide failover protection. They are often used in web architectures to distribute traffic across servers providing services such as web hosting, email, and other applications. A load balancer can also be used in larger-scale systems such as big data clusters and distributed computing environments.
How does a load balancer work?
A load balancer uses one or more methods to distribute network traffic among the servers or hosts in the system. The most common method is to use a round-robin algorithm, where each connection is directed to the next host in a sequential order. In some systems, the connection to the host is terminated and then a new connection is created between the client and the host. This type of load balancing is referred to as “full-proxy” or “end-end” load balancing. The other common method is to use an “inline” method, where the connections are directly between the clients and the hosts.
Microsoft’s Always On VPN and Kemp Load Balancer
