4️⃣ Serverless Deployment

🚧 Documentation in progress - This section is currently being developed

Serverless deployment provides a cost-effective, auto-scaling solution for AstrNest, suitable for production environments with variable workloads.

Overview

Serverless deployment leverages cloud platforms to automatically manage infrastructure, scaling, and availability. This approach eliminates the need for server management while providing high availability and cost optimization.

Prerequisites

• Cloud Platform Account (AWS, Azure, Google Cloud, etc.)
• Serverless Framework or platform-specific CLI tools
• Database Service (cloud-managed MySQL/PostgreSQL)
• Object Storage (for file storage)

Quick Start

Quick start guide will be available once serverless deployment is fully implemented.
