src=\"https:\/\/bonghosting5.wordpress.com\/wp-content\/uploads\/2026\/05\/how-serverless-architecture-works-bonghosting.webp.jpg\" alt=\"How serverless architecture works infographic showing event triggers cloud functions and automatic scaling workflow with BongHosting branding\" width=\"1000\" height=\"667\" \/><\/p>\n<p>Serverless systems usually work like this:<\/p>\n<ol>\n<li>User triggers an event<\/li>\n<li>Cloud platform activates a function<\/li>\n<li>Code executes automatically<\/li>\n<li>Resources scale dynamically<\/li>\n<li>Function stops after execution<\/li>\n<\/ol>\n<p>This process is highly automated.<\/p>\n<h2>What Are Cloud Functions?<img decoding=\"async\" class=\"alignnone\" src=\"https:\/\/bonghosting5.wordpress.com\/wp-content\/uploads\/2026\/05\/cloud-functions-explained-bonghosting.webp.jpg\" alt=\"Cloud functions explained infographic showing event-driven functions API triggers and serverless execution workflow with BongHosting branding\" width=\"1000\" height=\"667\" \/><\/h2>\n<p>Cloud functions are small pieces of code that run in response to events.<\/p>\n<p>Functions can trigger from:<\/p>\n<ul>\n<li>API requests<\/li>\n<li>File uploads<\/li>\n<li>Database changes<\/li>\n<li>User actions<\/li>\n<li>Scheduled tasks<\/li>\n<\/ul>\n<p>Cloud functions are core components of serverless architecture.<\/p>\n<h2>Traditional Hosting vs Serverless Computing<\/h2>\n<p><img decoding=\"async\" class=\"alignnone\"
