Alternative to EC2 for running ML batch training jobs on AWS

We are building an ML pipeline on AWS, which will obviously require some heavy-compute components including preprocessing and batch training.

Most the the pipeline is on Lambda, but Lambda is known to have time limits on how long a job can be run (~15mins). Thus for the longer running jobs like batch training of ML models we will need(?) to access something like EC2 instances. For example a lambda function could be invoked and then kick off an EC2 instance to handle the training.

Are there any alternatives to using EC2 for the heavy compute? Is there a way to still host/run the job on AWS without leveraging any EC2 to do the compute?

The idea is to avoid the extra management that comes with EC2 since we’re not currently using it. Keeping everything ad close to Lambda-like as possible is ideal.
