Our devops is currently managed by 3rd party consutancy and we're looking to take over over the next 6 months. I got AWS associate level certifications and will take over devops.

App is Rails monolith running on few EC2 with Capistrano used for deploys. RDS, redis etc, usual suspects, all hosted in AWS.

This migration may be a chance to setup things differently.

What architecture would you advise? what are the pros and cons of ElasticBeanstalk vs ECS vs doing the way we're doing it now.

Any articles/resources would be greatly appreciated. Thank you.
