Step-by-step explanation:
A cost-effective serverless solution for the small business's flagship application with both static and dynamic content can be achieved using AWS Lambda and Amazon S3. AWS Lambda is a serverless compute service that allows you to run your code without provisioning or managing servers. Amazon S3 is a highly scalable and cost-effective storage service.
To implement the solution, you can store the static content, such as HTML, CSS, and images, in an S3 bucket. The dynamic parts of the application can be handled by Lambda functions triggered by API Gateway.
By utilizing serverless computing, you can save costs by only paying for the actual usage of resources and not for idle time. Additionally, Amazon S3 provides cost-effective storage options and the ability to automatically scale to accommodate increasing data needs.
