Even AWS and Azure have outages. Sometimes for hours. If your business runs on cloud and you haven't designed for cloud-going-down, you don't have a backup strategy — you have a hope. We build real disaster-recovery architectures: multi-region, multi-zone, tested twice a year.
Our entire stack ran there. So did our backups. So did our DNS. So did our monitoring. So did us.
Attacker has admin. They delete the snapshots before the encryption sweep. Now there's nothing.
Day-of-disaster is not the time to learn the restore process doesn't actually work.
Plan says 4-hour recovery. Last time it took two days. Plan never updated.
Critical workloads replicate to a second region. Failover tested. RTO under 1 hour for tier-1 systems.
Backups stored in a separate AWS account or Azure subscription. Compromised primary → backups untouched.
Object lock or immutable vault. Even an admin can't delete the backup before its retention expires.
Twice a year we fail over to the secondary region for real. Documented runbook, every step verified.
Real numbers based on tested recovery, not best-case math. Per workload tier.
Step-by-step what to do, who to call, how to know it worked. Updated after every drill.
Most firms are at level 2 and think they're at level 4.
| Backup only | Multi-AZ | Multi-region | Active-active | |
|---|---|---|---|---|
| Survives instance failure | No | Yes | Yes | Yes |
| Survives data-center failure | No | Yes | Yes | Yes |
| Survives region failure | No | No | Yes (failover) | Yes (transparent) |
| Survives account compromise | Maybe | Maybe | Yes (cross-account) | Yes |
| Typical recovery time | Hours–days | Minutes | 30–60 minutes | Seconds |
| Cost overhead | Lowest | +10–20% | +30–60% | +80–120% |
| Best for | Dev / test | Most workloads | Revenue-critical | Mission-critical |
Recovery time objective for revenue-critical workloads. Tested, not estimated.
Recovery point — maximum data loss in a region-failover scenario.
Twice a year. Real failover. Documented.
In the last 5 years. We don't move on until the drill passes.
“When us-east-1 went out last year, half of our competitors were down for the whole afternoon. We failed over to us-west-2 in 47 minutes. Senator's design held up — and the DR drills we did six months earlier meant we knew exactly what to do.”
For most workloads, yes. But for revenue-critical systems, AZ-level redundancy doesn't help when an entire region has an outage — and those do happen, every couple of years.
30–60% premium over single-region for the replicated workloads. Cheaper than the cost of an actual region-level outage for any serious business.
Twice a year is our standard. Annual minimum for compliance. Quarterly for the most critical environments.
Possible but expensive and complex. We rarely recommend it unless there's a regulatory or strategic reason. Multi-region within one cloud is usually the right answer.
We review your current architecture, identify the single points of failure, and propose what tier of DR makes sense per workload. Written report in 5 business days.
