Converting a serverless application to a traditional microservice application

I want to convert an application that use AWS Eventbridge, Dynamodb, AWS S3, AWS SES, AWS SQS and AWS API gateway to a traditional microservice application. So in my understanding AWS Eventbridge can be replaced with a NATS streaming server, Dynamodb can be replaced with Mongodb and AWS API gateway can be replaced with a Node.js Express server, but I am not sure what I can use to replace AWS S3, AWS SES and AWS SQS.
