Single affinity should also be used for any application that uses sessions lasting over multiple TCP connections to ensure that the entire session is mapped to the same server. Finally, single affinity must be used if your client sessions use the secure sockets layer (SSL) to connect to NLB servers.
When should single affinity be used?

If the important thread comes, Affinity is useful to set and reserve a core. Affinity helps to ensure that thread always runs on the “best” core. Sometimes it is worth to deny a process to run on the particular core of CPUs or CPUs itself. In this case, even if the CPU core is available to run the process, it will not run.

What affinity is responsible for when setting up NLB?
With Class C affinity, NLB associates clients with particular members by using the Class C portion of the client's IP address. Thus, clients coming from the same Class C address range always access the same member. This affinity provides the best performance for clusters serving the Internet.
What is affinity in load balancing?
Session affinity is a feature available on load balancers that allows all subsequent traffic and requests from an initial client session to be passed to the same server in the pool. Session affinity is also referred to as session persistence, server affinity, server persistence, or server sticky.
How does session affinity work?
Session affinity uses cookies to track session information and, potentially, to maintain login credentials. With session affinity, the application server that handles the first client request generates session information and places it in a Set-Cookie header in the response.

Session affinity, also known as “sticky sessions”, is the function of the load balancer that directs subsequent requests from each unique session to the same Dgraph in the load balancer pool.
What is difference between ALB and NLB?
NLB natively preserves the source IP address in TCP/UDP packets; in contrast, ALB and ELB can be configured to add additional HTTP headers with forwarding information, and those have to be parsed properly by your application.
What is the benefit of a network load balancing cluster?
The Network Load Balancing (NLB) feature distributes traffic across several servers by using the TCP/IP networking protocol. By combining two or more computers that are running applications into a single virtual cluster, NLB provides reliability and performance for web servers and other mission-critical servers.
How many servers can you have in one NLB cluster?
32 serversA Network Load Balancing cluster can scale up to 32 servers. Systems administrators and networking administrators can manage the Network Load Balancing feature through Microsoft's NLB Manager or with PowerShell cmdlets.
What is load balancing persistence or affinity?
Session stickiness, a.k.a., session persistence, is a process in which a load balancer creates an affinity between a client and a specific network server for the duration of a session, (i.e., the time a specific IP spends on a website).
How do I enable affinity in load balancer?

What is cookie based affinity?
Cookie-based affinity When a user sends the first request to Application Gateway, it sets an affinity cookie in the response with a hash value which contains the session details, so that the subsequent requests carrying the affinity cookie will be routed to the same backend server for maintaining stickiness.
