Well-Architected Serverless Lens
Introduction
The Well-Architected Serverless Lens provides guidance to help you evaluate your serverless applications against the AWS Well-Architected Framework. This lens focuses on the specific aspects of serverless architecture that are critical for success.
Key Concepts
1. Serverless Architecture
Serverless architecture allows developers to build and run applications without managing infrastructure. It automatically scales based on the demand.
2. AWS Services
Key AWS services used in serverless architectures include:
- AWS Lambda
- AWS API Gateway
- AWS DynamoDB
- AWS S3
3. Well-Architected Framework Pillars
The framework consists of five pillars:
- Operational Excellence
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
Best Practices
- Use AWS Lambda to run your code without provisioning servers.
- Implement API Gateway for managing and securing your APIs.
- Utilize DynamoDB for scalable data storage.
- Leverage S3 for file storage and hosting static websites.
