I would consider Azure App Service for your deployment. This is a fully managed platform that allows you to build, deploy, and scale web apps and APIs using Node.js. You can choose from different pricing tiers depending on your needs, such as memory, CPU, and storage. You can also use features such as custom domains, SSL certificates, continuous deployment, and autoscaling.

If you want the stack to operate and be managed more like a traditional server you can deploy on Virtual Machines.
If you want further suggestions I highly recommend reaching out to Azure sales. You can contact Azure sales to get help with choosing the best option for your needs. They can provide you with more information about the different Azure services and plans, and help you select the one that best fits your requirements. You can chat with a sales representative or request a call back from a sales specialist
