Local realities.
WHAT CONSTRAINS WORK HERE
Bandwidth cost for large transfers Latency to distant servers Power affecting on-premises systems Foreign-currency pricing for managed services
WHAT BANDWIDTH AFFECTS
Downloading backups Restoring from off-site copies
WHAT TO DO ABOUT IT
Compress before transferring Transfer server to server directly Keep a local copy for speed and a remote one for safety
WHY THE LOCAL COPY MATTERS
Restoring from a distant backup over a slow link can take longer than the outage you are fixing.
WHAT LATENCY AFFECTS
Applications separated from their database by distance.
WHY THAT MATTERS ENORMOUSLY
Each query pays the round trip, and applications issuing many queries become unusable.
WHAT TO DO
Keep application and database close, ideally on the same network.
WHAT POWER AFFECTS
On-premises servers, where unclean shutdown causes corruption.
WHAT PREVENTS IT
Backup power sufficient for a clean shutdown Durability settings that do not trade safety for speed
WHAT TO VERIFY ABOUT MANAGED SERVICES
Where data resides What it costs at your size, in local terms Whether you can export it
WHAT TO PLAN FOR
Costs rising with the exchange rate.
WHAT TO KEEP LOCALLY
Documentation and restore procedures.
