ruby on rails - How to create server (failover) redundancy and reliability solution -


i looking way redirect traffic heroku application instance else when heroku/aws experiencing downtime.

i envision along these lines love feedback , other ideas.

  1. app running on heroku(or wherever) returns error.
  2. request redirect fallback url (i have far set up)
  3. this url contains clone (db included) of original application.
  4. this clone can read want avoid having sync db , forth.

i reasonably efficient way of keeping dbs in uptodate every 30-60 minutes or well. not sure how this. thought docker might start more dynamic deploy. goal have redundancy , not tied using heroku app resides.

am missing something? reasonable implement? taking time.

[update] found this. although of light, little can use because set quite ways off 1 used.

heroku paas, easy & fast server setup.

when application start growing big enough, suggest change iaas virtual machine example aws, google cloud platform, azure, etc.
