Evaluate AWS Lambda for Scorer Service Performance & Cost Efficiency

[nutrina]

Background

This task is a continuation of issue #1646 and aims to assess the efficacy and cost-effectiveness of using AWS Lambda to serve our Scorer API.

Objectives

Run load tests to measure AWS Lambda's performance under varying conditions:

• Submit-Passport Request: Target this specific request as it is one of our slowest endpoints.
• Ceramic-Cache Operations: Run tests for requests that interact with reads and writes from the ceramic-cache.

Analyze and compare the results with previous load tests to answer the following:

• Scalability: Can this setup manage sudden spikes in load without degradation in performance?
• Cost Analysis: Provide estimates for the costs involved in using AWS Lambda compared to using AWS Fargate.

Open Issues & Concerns

• Rate Limits: Identify the request-per-second limitations of this setup.
• Cost Management: Explore mechanisms to keep AWS Lambda costs in check without compromising performance.

Rate limit & cost management are to be clarified in this ticket: #405
