mongodb - scalable meanjs on digitalocean -


i'm trying learn deployment process can guarantee headackeless scaling of meanjs application (not in level people in big companies, not @ hobby level).

so long understood, solution work on: 1. having mongodb on digitalocean on ubuntu 2. having meanjs application (all other mongodb) in docker

then 1 can scale! because mongodb clustered separately , docker keeps scaling of application easy.

well, know sounds trivial , that's why i'm asking here: want go , learn docker , want make sure before investing time on above assumed solution!

do think guarantee easy scaling, say, simple online multiplayer game on meanjs please? thank you.

there no off shelf solution.

you can use docker swamp small deployment brings additional issues of monitoring , networking.

so here did:

  1. create script generate haproxy config when start/stop instance
  2. have mongo in cluster or replica or whatever. database not need scaled dynamically. have single mongo server scale , when can't scale vertically anymore scale horizontally creating replica set , scale until can't sharding.

so have haproxy load balancer accepts connections on port 80 , forwards droples oven private network. can write scripts use api create image deployment , fire once have more traffic either dynamically detecting response time or cpu load or whatever other metric have or statically.

i hope helps.

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
