Deadline: Thursday, December 12, @23:59 pm Scenario Overview
You are tasked with creating a serverless architecture on AWS. Host a professional resume website on AWS and add a real-time visitor counter that updates with each page load. You can use S3 to host a static website, AWS Lambda to update the number of visitors in a DynamoDB table, and API Gateway to expose the Lambda function as an endpoint.
AWS Services Involved:
General Requirements:
Implementation: Two codes snippets are provided to you: one for the resume HTML and one for the Lambda function. You just need to replace some placeholders, understand what is happening in the code in general and do tweaks if needed. You need to:
o Attribute: count (stores the number of visitors). The value will be incremented with each page load.
Ensure that the Lambda function is configured to trigger through API Gateway and returns the visitor count correctly.
Evaluation Criteria:
traditional server-based structures.
