Reliability and Availability

Recognize Downtime as a Business Risk: Explain why downtime is a business continuity issue, not just a technical one, and connect single-server architectures to extended recovery time, data loss risk, operational fragility, revenue impact, and customer trust.

Understand Built-In Replication and Automatic Failover: Describe how MongoDB replica sets maintain multiple copies of data and how automatic failover detects failures and promotes a new primary in seconds without human intervention, reducing outage impact and supporting strong recovery targets.

Select the Right Distribution Strategy: Evaluate availability zones, multi-region, and multi-cloud deployments to match your architecture to application criticality, business continuity requirements, and long-term operational confidence.
