In today’s security-driven software landscape, controlling access to resources is crucial. Two dominant access control models— RBAC and ABAC —help teams manage permissions, but they differ significantly in flexibility, complexity, and use cases. Let’s dive into what sets them apart and when to use each. What is Role-Based Access Control (RBAC)? RBAC assigns permissions to users based on roles they belong to (e.g., Admin, Editor, Viewer). Pros: Simple and easy to manage Scalable for small to mid-sized teams Industry-standard for enterprise apps Cons: Limited flexibility Role explosion in complex systems Example: A user with the "Manager" role can view and edit employee records but cannot delete them. What is Attribute-Based Access Control (ABAC)? ABAC evaluates user attributes , resource attributes, and environmental conditions (e.g., time, location) to determine access. Pros: Highly flexible and fine-grained Context-aware security Better suited for dynamic or multi-tenant ...

The serverless paradigm is transforming how developers build and deploy modern applications. Traditionally, managing back-end infrastructure meant provisioning servers, scaling systems, and maintaining uptime. But with serverless architecture, much of that burden is lifted—allowing developers to focus solely on building features. Let’s explore how serverless works for both the front-end and back-end , its benefits, and where it shines the most. What is Serverless? Despite its name, serverless doesn’t mean there are no servers. It means you don’t manage them . Cloud providers handle provisioning, scaling, and infrastructure management. You deploy your code, and it runs when triggered—often priced by usage. Popular serverless platforms include: AWS Lambda Azure Functions Google Cloud Functions Vercel / Netlify (for front-end) Serverless for the Front-End Serverless on the front-end often refers to deploying web apps on platforms like: Vercel Netlify Cloudflare Pages These platforms su...
