DR-Testing

Designing Resilient Data Centers and Cloud Architectures Resilience is the steady backbone of modern IT. When apps rely on data, users expect uptime. A single outage can ripple through revenue, trust, and compliance. Designing resilient data centers and cloud architectures means preparing for power faults, network failures, and software bugs before they happen. Think of resilience in three layers: physical infrastructure, logical design, and operational practices. For physical resilience, plan for redundant power feeds, uninterruptible power supplies, backup generators, and cooling that can handle peak load. For logical design, use redundant storage, multiple compute nodes, and automated failover. For operations, run regular drills, monitor health, and document recovery steps. ...

Disaster Recovery for Cloud Environments Cloud environments offer rapid recovery when they are well planned. Disaster recovery (DR) is the practice of restoring critical systems after a disruption. In the cloud, you can leverage replication, backups, and automation to reduce downtime while controlling costs. The goal is to return to normal operations quickly and keep data safe. What to know: RTO: time to restore services. RPO: amount of data you can lose. Patterns: active-active, active-passive, or warm standby. Failover vs failback: switching traffic, then returning. Plan and design: ...
