We tested NodeJS workers in AWS EBS using slightly different architectures:
sqsd provided out-of-the-box (OOTB) in an AWS VM which would pull from SQS and hand a message to our worker.
with a nodejs sqsd standalone component which would pull from SQS and hand a message to our worker.
with our worker pulling a message directly from SQS itself.
This is similar to the architecture described for PHP workers in AWS EBS with one important distinction, the
supervisor isn't involved.
