linux - Zero downtime deploy with node.js and mongodb? -

i'm looking after building global app ground can updated , scaled transparently user.

the architecture far easy, each part of application has own process , talk other trough sockets.

this way can spawn many instances want each part of application , distribute them across globe accordingly needs.

in front end of scheme i'll have load balancer, them route users closest instance, , when new code spawned instances spawn new processes new code , route new requests , gracefully shutdown.

thank much advice.

edit:

the question is: best ( , simplest ) solution achieving 0 downtime when deploying node multiple instances ?

about app:

https://github.com/raynos/boot "socket" connections, http http requests, mongo database

solutions i'm trying @ moment:

https://www.npmjs.org/package/thalassa ( managed haproxy configuration files , app instances ), if don't know it, watch talk: https://www.youtube.com/watch?v=k6qknt4hzwq , aware crowsnest beingness replaced https://github.com/pearsoneducation/thalassa-consul

deployment 0 downtime possible if info share between old , new nodes compatible.

so in case alter structure, have build intermediate release, can handle old , new info construction without utilizing new construction until have replaced nodes intermediate version. roll out new version.

taking nodes in , out of production can done loadbalancer (and grace time until sessions expired on nodes) (don't know plenty application).

linux node.js mongodb deployment
