How to monitor AWS infrastructure&workloads using Elasticsearch integration

Question

It is needed to intagrate AWS with Elasticsearch, I have found a couple of articles which describe general process:

1. Create and configure an S3 bucket
2. Create and configure an SQS queue.
3. Install and configure Filebeat and Metricbeat to collect Logs and
4. Metrics Collect logs from S3
5. Collect metrics from Amazon CloudWatch

f/e https://www.elastic.co/guide/en/observability/current/monitor-aws.html#monitor-aws

The question is where Filebeat and Metricbeat suppose to be installed f.e if I have complex infra with serverless items?

I also tried to connect with aws access and secret key in elasticsearch policies, bu no luck(data is not picked up)
