The easiest option is to install an EC2 from an existing template in IOC, there should be plenty in Terraform or pulumi . Beware of the ones that use the NAT gateway, they can be expensive in case your need a lot of traffic for the batch data. You can the internet gateway. Once the ec2 is setup and patched, ssh to it, install lein and upload your data. I've done a similar setup on my Raspbery pi.
But you can consider running the jobs on the local machine overnight, persist the results and read them in repl the next day. it will save you a lot of hassle and let you focus on the problem instead of infrastructure
