“Smart Solutions with Serverless: Event-Driven AWS Lambda in Action”

stp2y0 CommentsNews, , , , , , , ,
Serverless computing is a cloud computing paradigm that abstracts away server management, allowing developers to focus solely on writing and deploying code. Here's a breakdown of the core concepts: No Server Management: In traditional deployments, developers manage servers, including provisioning, scaling, and patching. Serverless computing eliminates this burden. The cloud provider handles infrastructure management, freeing developers to concentrate on application logic. Pay-Per-Use Model: Serverless platforms charge based on resource consumption, typically execution time and memory used. This translates to cost-effectiveness, especially for applications with variable workloads. You only pay for the resources your code utilizes. Event-Driven Architecture: Serverless functions are…
