Flightcontrol is very popular for Next.js deployments on AWS

But of course AWS is a nightmare on it's own.
So you might like Flightcontrol [1] which provides a PaaS user experience on your own AWS, thereby giving you the best of both worlds.
Today, the server deployments use Fargate, and are truly hands off just like PaaS. Soon we're launching ECS+EC2 support which will let you customize the EC2 instance type, use GPUs, and leverage reserved instances. ECS doesn't offer some advanced k8s features, but it's 80% or more of the benefit in an easier to use, cheaper package.
We commonly see Series A & B companies migrating off PaaS to Flightcontrol + AWS because they can keep the same workflows while gaining more reliability, control, and flexibility.
I'm cofounder, CEO. Let me know if you have any questions.
