Mastering AWS Serverless: Build and Deploy Applications
- AWS serverless architecture enables developers to focus on writing code without managing servers.
- AWS Serverless offers benefits like automatic scaling, cost efficiency, no upfront costs, and faster development.
- The core services for building and deploying serverless applications on AWS include AWS Lambda, Amazon API Gateway, Amazon DynamoDB, and Amazon S3.
- AWS Lambda is a compute service that lets you run code without provisioning or managing servers that scales your application automatically based on demand.
- Amazon API Gateway allows you to build RESTful and WebSocket APIs, which can easily integrate with other AWS services like AWS Lambda and others.
- Amazon DynamoDB is a serverless NoSQL database service that offers seamless scalability with great performance. It is best for serverless architectures that require efficient data storage.
- Amazon S3 provides scalable object storage for serverless applications and has built-in serverless triggers that invoke AWS Lambda functions.
- Building serverless applications with AWS involves designing your application architecture, creating a Lambda function with the required triggers, setting up API Gateway routes, persisting data in DynamoDB database, and storing and processing files in S3 bucket.
- Best practices for AWS Serverless Applications are minimizing cold starts, using IAM Roles, monitoring with CloudWatch, and leveraging AWS X-ray to trace requests and identify performance issues.
- AWS Serverless allows developers to innovate faster, reduce costs, and focus more on delivering business value rather than running infrastructure.
