Serverless architecture

Serverless architecture is a cloud-computing model where developers build and run applications without managing ser vers. Instead of provisioning, maintaining, and scaling servers, developers rely on cloud providers (like AWS Lambda, Google Cloud Functions, or Azure Functions) to automatically handle the infrastructure. In this model, developers write functions or small units of code that are triggered by events (e.g., user actions, data changes, or API calls), and these functions run on-demand in a fully managed environment.

Key benefits of serverless architecture include:

• Cost Efficiency: Since you only pay for the compute time your code actually uses (measured in milliseconds), there’s no need to pay for idle server time, making it highly cost-effective for many use cases.
• Scalability: Serverless platforms automatically scale applications up or down based on demand, handling traffic spikes seamlessly without manual intervention.
• Faster Development: Developers can focus on writing business logic rather than managing infrastructure, speeding up development and deployment cycles.
• Reduced Maintenance: With infrastructure managed by cloud providers, there’s less need for system administration, updates, and patches, allowing developers to focus on application features.

Serverless is ideal for event-driven applications, microservices, APIs, and real-time data processing, but it may not be suitable for long-running, resource-intensive tasks.
