AWS Serverless Identity Server 4 with quickstart UI

I would like to run Identity Server 4 as a .NET Core 3.1 with its UI, if possible in Amazon Web Services serverless eco system. What would be the best approach ?

• AWS Lambda (using Amazon.Lambda.AspNetCoreServer package)

• AWS Elastic Beanstalk (using Amazon.Lambda.AspNetCoreServer package)

• AWS EC2 instances with load balancers (not quite serverless...)
