Not sure how to set up my dns and heroku apps to do what I want -

-

heroku offers , eu servers , want users connect server closer them, if connects eu, redirect them eu server , same us.

my idea have them connect main domain name, example.com connect server, check users coming from, , redirect them want them be, , while looking @ same domain "example.com". heroku wont let me add same domain twice, , don't know should configure dns. domain provider has nameserver section , i'm not sure add there. want request , server load go onto heroku page, , not onto default dns server redirects or loads heroku page inside frame.

they way seems correct, connect example.com, heroku page , redirect inside frame or eu page... not sure if best way, , mentioned, i'm not sure how setup namespace , stuff connect directly heroku server instead of default domain server.

could explain me need achieve want?

it not possible run multi-region application on heroku , i'd caution against trying work way around limitation. areas cause users problems when trying attempt are:

  • you can't have same custom domain on 2 apps (as you've identified).
  • there no way setup multi-master database configuration each app has db in own region. likewise, maintaining single master both apps results in high latency 1 of apps.
  • the connection overhead of other trickery, propose here, negates latency improvement user sees accessing app in closest region.
  • using cdn static assets, , having proper http cache header strategy gets 90% of way performance of geo-distributed app.

to drill further question, i'm not sure mean here?

how setup namespace , stuff connect directly heroku server instead of default domain server

hope helps!

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
