Layer 4 load balancing uses information defined at the networking transport layer (Layer 4) as the basis for deciding how to distribute client requests across a group of servers. For Internet traffic specifically, a Layer 4 load balancer bases the load-balancing decision on the source and destination IP addresses and ports recorded in the packet header, without considering the contents of the packet. There are seven networking layers in all, defined by the Open Systems Interconnection [OSI] Refe...
What Is DNS Load Balancing? ; DNS load balancing distributes incoming network traffic across multiple servers or resources to improve the availability, scalability, and performance of a service or application by spreading the load among several server instances. It presents a simple and efficient way to achieve load distribution among multiple servers. The DNS is often described as the Internet's phonebook because it translates website domain names (such as f5.com or amazon.com) into numeric IP ...

The Random with Two Choices load-balancing algorithm is NGINX's implementation of the "power of two choices" method. This biased random algorithm has been shown to be effective at balancing loads w...
In Load Balancing with NGINX and NGINX Plus, Part 1, we set up a simple HTTP proxy to load balance traffic across several web servers. In this article, we’ll look at additional features, some of them available in NGINX Plus: performance optimization with keepalives, health checks, session persistence, redirects, and content rewriting. For details of the load‑balancing features in NGINX and NGINX Plus, check out the NGINX Plus Admin Guide. Editor – NGINX Plus Release 5 and later can also load balance TCP-based applications. TCP load balanc ...
NGINX is a capable accelerating proxy for a wide range of HTTP‑based applications. Its caching, HTTP connection processing, and offload significantly increase application performance, particularly during periods of high load. You configure TCP and UDP load balancing in the stream context instead of the http context. The available directives and parameters differ somewhat because of inherent differences between HTTP and TCP/UDP; for details, see the documentation for the HTTP and TCP Upstream m...
Thank you Paulius I test it, and really the status changes to Unavailable (Enabled) - The pool member's connection limit has been reached ; I configured two servers in the pool ; server 1 - connection limit 2 | priority group 20
Load balancing across multiple application instances is a commonly used technique for optimizing resource utilization, maximizing throughput, reducing latency, and ensuring fault‑tolerant configurations. Watch the F5 NGINX Plus for Load Balancing and Scaling webinar on demand for a deep dive on techniques that NGINX users employ to build large‑scale, highly available web services. NGINX and NGINX Plus can be used in different deployment scenarios as a very efficient HTTP load balancer. ...
