Resilience and Continuity

Resilience and continuity are shared responsibility topics because provider uptime is not the same thing as workload resilience. Providers can keep the platform available while the customer’s own architecture, data strategy, failover design, and recovery processes still determine whether the business service survives disruption.

This chapter makes that distinction concrete. The lessons compare platform availability with workload availability, walk through backup and snapshot responsibilities, examine multi-zone, multi-region, and cross-provider design, and finish with the ownership model for business continuity and disaster recovery. Together, they show why continuity planning belongs to the customer side even when the provider offers powerful resilience features.

Read This Chapter Looking For

• which resilience outcomes can be inherited and which must be engineered by the customer
• how recovery objectives depend on workload design, data strategy, and operating procedures rather than provider SLAs alone
• where continuity planning fails when architecture and governance are designed separately

Use this chapter when an uptime promise is being mistaken for a business continuity strategy.

In this section

• Availability of the Platform vs Availability of the Workload
  Platform availability and workload availability are related, but they are not the same thing.
• Backup Strategies, Snapshots, and Recovery Plans
  Backup strategy does not come pre-solved with provider tooling.
• Multi-Zone, Multi-Region, and Cross-Provider Thinking
  Multi-zone, multi-region, and cross-provider design are customer architecture choices, not provider defaults.
• Business Continuity and Disaster Recovery Ownership
  Business continuity and disaster recovery ownership remain on the customer side even when the cloud platform is highly resilient.
