If you are a beginner, developer, startup founder, or tech enthusiast, this guide is written especially for you.<\/p>\n\n\n\n<p><strong>Serverless computing is often misunderstood because of its name<\/strong>. Many people think it means <strong>\u201cno servers at all,\u201d<\/strong> but that is not true. In reality, servers still exist \u2014 the difference is that <strong>you don\u2019t need to manage them<\/strong>. The cloud provider takes full responsibility for infrastructure, scaling, and maintenance.<\/p>\n\n\n\n<p>In today\u2019s fast-moving digital world, businesses want speed, flexibility, and cost efficiency. Serverless computing helps achieve exactly that by allowing developers to focus only on code instead of worrying about servers, operating systems, or capacity planning.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2240\" height=\"1260\" src=\"https:\/\/www.oflox.com\/blog\/wp-content\/uploads\/2026\/01\/What-Is-Serverless-Computing.jpg\" alt=\"What Is Serverless Computing\" class=\"wp-image-33751\" srcset=\"https:\/\/www.oflox.com\/blog\/wp-content\/uploads\/2026\/01\/What-Is-Serverless-Computing.jpg 2240w, https:\/\/www.oflox.com\/blog\/wp-content\/uploads\/2026\/01\/What-Is-Serverless-Computing-768x432.jpg 768w, https:\/\/www.oflox.com\/blog\/wp-content\/uploads\/2026\/01\/What-Is-Serverless-Computing-1536x864.jpg 1536w, https:\/\/www.oflox.com\/blog\/wp-content\/uploads\/2026\/01\/What-Is-Serverless-Computing-2048x1152.jpg 2048w\" sizes=\"auto, (max-width: 2240px) 100vw, 2240px\" \/><\/figure>\n\n\n\n<p>We\u2019re exploring \u201c<strong>What Is Serverless Computing<\/strong>\u201d in this article, with all the key information at your fingertips.<\/p>\n\n\n\n<p>Let\u2019s explore it together!<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-69fe249b9e695\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-69fe249b9e695\"  aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.oflox.com\/blog\/what-is-serverless-computing\/#What_Is_Serverless_Computing\" >What Is Serverless Computing?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.oflox.com\/blog\/what-is-serverless-computing\/#Why_Is_It_Called_%E2%80%9CServerless%E2%80%9D\" >Why Is It Called \u201cServerless\u201d?<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.oflox.com\/blog\/what-is-serverless-computing\/#1_The_reality\" >1.
