By distributing incoming network traffic across multiple servers, load balancers ensure optimal resource utilisation, improved responsiveness, and enhanced fault tolerance. Let&#8217;s explore how load balancing works in practice and examine some real-world success stories.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<h3 id=\"t-1737104913951\"><span data-contrast=\"none\" lang=\"EN-US\"><span data-ccp-parastyle=\"heading 2\">How Load Balancing Works<\/span><span data-ccp-parastyle=\"heading 2\">?<\/span><\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;335559738&quot;:160,&quot;335559739&quot;:80}\">&nbsp;<\/span><\/h3>\n<p><span data-contrast=\"auto\" lang=\"EN-US\">At its core, load balancing involves distributing incoming requests across a group of backend servers, also known as a server pool or server farm. When a client sends a request, the load balancer intercepts it and forwards it to one of the available servers based on a predefined algorithm.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><span data-contrast=\"auto\" lang=\"EN-US\"><\/span><span data-contrast=\"auto\" lang=\"EN-US\">Some common load balancing algorithms include:<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p>\n<ul>\n<li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Round Robin: <\/strong>Requests are distributed sequentially to each server in turn.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Least Connections: <\/strong>Requests are sent to the server with the fewest active connections.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>IP Hash: <\/strong>The client&#8217;s IP address is used to determine which server receives the request.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Weighted Round Robin: <\/strong>Servers are assigned different weights based on their capacity.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li>\n<\/ul>\n<p><span data-contrast=\"auto\" lang=\"EN-US\">Each algorithm has its strengths and is suited for different scenarios.

data-contrast=\"auto\" lang=\"EN-US\">Load balancing is a critical component of modern web infrastructure, enabling websites and applications to handle high traffic volumes efficiently and reliably. By distributing incoming network traffic across multiple servers, load balancers ensure optimal resource utilisation, improved responsiveness, and enhanced fault tolerance. Let's explore how load balancing works in practice and examine some real-world success stories.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p><\/div><div class=\"thrv_wrapper thrv_text_element\"><h3 class=\"\" id=\"t-1737104913951\"><span data-contrast=\"none\" lang=\"EN-US\"><span data-ccp-parastyle=\"heading 2\">How Load Balancing Works<\/span><span data-ccp-parastyle=\"heading 2\">?<\/span><\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;335559738&quot;:160,&quot;335559739&quot;:80}\">&nbsp;<\/span><\/h3><p><span data-contrast=\"auto\" lang=\"EN-US\">At its core, load balancing involves distributing incoming requests across a group of backend servers, also known as a server pool or server farm. When a client sends a request, the load balancer intercepts it and forwards it to one of the available servers based on a predefined algorithm.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><span data-contrast=\"auto\" lang=\"EN-US\"><\/span><span data-contrast=\"auto\" lang=\"EN-US\">Some common load balancing algorithms include:<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/p><ul class=\"\"><li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Round Robin: <\/strong>Requests are distributed sequentially to each server in turn.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li><li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Least Connections: <\/strong>Requests are sent to the server with the fewest active connections.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li><li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>IP Hash: <\/strong>The client's IP address is used to determine which server receives the request.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li><li><span data-contrast=\"auto\" lang=\"EN-US\"><strong>Weighted Round Robin: <\/strong>Servers are assigned different weights based on their capacity.<\/span><span data-ccp-props=\"{}\">&nbsp;<\/span><\/li><\/ul><p><span data-contrast=\"auto\" lang=\"EN-US\">Each algorithm has its strengths and is suited for different scenarios.
