Question

I want to explore how to use Go in the

following architecture:

I'm running a couple of dozen NodeJS fat processes (50+Mb RES ram each, some >150Mb), all different workloads. They are all managed by a supervisord instance.

Each process connects to a RabbitMQ broker and to a PostgreSQL RDBMS, and is responsible of one or two message queues. Each message received is mapped to a function, and after processing, a reply message is sento back to the broker where it's routed to the originating web browser (mostly) and/or to other NodeJS consumers. The browsers are connected directly to rabbitMQ trough a STOMP over WS adapter.

All of this is the backend of a B2C web property; it works great, response times are consistent and I'm sure I can scale horizontally and outsource each important piece when the time comes.

Now, What would be the best practice if I wanted to decommission the fat NodeJS processes?

- Do I need a couple of dozen Go executables or only one?
- The couple of dozen proceses are currently there to allow me to fix/upgrade a small part of the site without disturbing anything else. How can I achieve this with Go?

Finally, the main reason I'm considering decomissioning the nodeJS processes is because I want to reduce the RAM consumption and be able to scale with smaller VMs and/or use simple containers (not multilayered ones, but simple, one image each). Another consideration is _npm install_; each deploy/upgrade cycle it's just a waste of resources and it increases the build time considerably.

- Would you consider this as valid reasons?

Thanks all.

I've heard of RabbitMQ but I'm still not sure I understand its uses or how to implement it

So your question is if you should have different go processes on the MQ?
