If you want to follow cloud native design patterns

• Service Discovery
• Inter-service messaging
• Request load balancing
• Service Presence and health

I would suggest using Hydra , its basically uses Express for creating API's and has inbuilt support for : hydramicroservice.com

• Automated health and presence
• Service discovery
• Inter-service communication with support for HTTP RESTful API and WebSocket messaging
• Self-registration with near zero configuration
• Built-in job queues

Seneca is another good framework for building applications following cloud native design patterns.

You can check the like microservice frameworks like Moleculer and senecajs.org They give in built options for your microservice stack.

Depending on your requirements, you might want to use the serverless framework. github.com/serverless/serverless

I think a MERN or MEAN stack in conjunction with a messaging service like RabbitMQ would be a very good way to go.

Did anyone already use studio and have feedback about it ? It's look simple, consise and very powerful!
