SQL Server High Availability on premise - cloud -


i know best way make copy , keep copies synchronized of on premises sql server 2008 (not r2) database sql azure.

think of sql azure failover kind of structure...

notes:

  • the database runs fine in sql azure
  • i have figured out how rest of app running on azure
  • please consider suggestions of type "upgrade sql server 2012 because of x" if gain (reliability, efficiency, time replicate, etc...) worth it
  • i`m looking instant replication (as fast possible)
  • yes have sync eventually. if on-premises deploy crash , cloud activated , changed, sync necessary, think not need automatic... of is, better!
  • the database consist of 900+ tables (legacy system)

i think best bet use sql data sync, should give bidirectional , use sync data around world in terms of datacenters , 1 local on premise database. give 5 mins sync timing do, otherwise next best options use sql server vms , old fashion way. sql azure data sync have found reasonable reliable , been running 6 months syncing across 4 database in 4 data centres in azure.

some problems though it,

  • it uses triggers.
  • it obivously add load , connections current sql database.
  • the new control panel in azure nightmare it, use old panel moment.
  • it in preview last time looked, might not 100% suitable you.

i imagine there better third party solutions out there off shelf , in azure sql data sync worth situation describing.
