You can get Heroku/Vercel/Render like experience on your AWS account with rock solid support from AWS.
Checkout https://localops.co if you guys are migrating away from Heroku.
(I'm the founder of LocalOps here)
App runtime: Connect your Github repo and AWS account in 1-click and get Heroku like-PaaS automation. Just push to your Github repo and we will deploy your code automatically. Zero cloud config or DevOps effort required.
Databases: Just add the databases you need on a json file and they will get auto-provisioned. AWS managed RDS (Postgres/MySQL), Elastic cache (Redis/Memcache). No need for manual provisioning or maintenance.
Zero downtime deployments.
No ceiling: Scale infinitely on your AWS account
Cost: 60-70% overall cheaper than any traditional PaaS alternatives like Heroku/Render because you are paying for infrastructure provider directly for all servers and paying LocalOps just for automation.
Support: Get rock solid support from AWS for infrastructure uptime.
