I would advise against Elastic Beanstalk, last time I used it the product had the stink of being on life support - they've not really added any new features to it in several years, and even before that it was incredibly flakey.
A concur. I got burned three times by Elastic Beanstalk in 2019 before switching away.
1. Their server manager process got in an unresponsive state. It wouldn't update my service. It stopped reporting logs from the service that was running. I went to the AWS Loft and consulted with the AWS Support technician. They had me log into the machine with SSH and troubleshoot. I was using Elastic Beanstalk specifically so I would not have to log into machines.
2. The console frequently showed servers as running when they weren't. And vice-versa. I wasted a lot of time trying to figure out why my server didn't start when it actually did start and why my server isn't listening on its port when the console incorrectly showed that it started. Logs were also delayed randomly.
3. The final straw happened on a Saturday. Elastic Beanstalk suddenly started returning errors. I purchased an AWS Support subscription and filed a ticket. It turns out Elastic Beanstalk Team had deployed on a Saturday and then rolled back. Unfortunately, anyone who did API calls through the new API version got new values added to their Elastic Beanstalk API backing database. The rolled-back the server errored when it saw the new values. They refused to just fix the bad data in their database caused by their bad deployment. Instead, they asked me (their customer) to download special management tools and perform manual operations to fix it. And I had to pay them to find out these instructions.
What additional features are you looking for? I've been using beanstalk for the past few years, and just wrapped up doing a large deployment on it. I've never found beanstalk to be a bottleneck or not have a feature I was looking for.
Recently Beanstalk got upgraded to their "Amazon Linux 2" making it basically pretty much a Heroku clone, you even set up Procfile and services ;-) It still requires a LOT of hacking and insider-knowledge to do some funkier things, but it's a great thing
I use Elastic Beanstalk daily it is maintained and supports everything on AWS, they've added ALB and WAP for example. It runs on Cloud Formation. Never experienced anything "flakey"
