Resilience starts with understanding what the business cannot afford to lose: critical services, acceptable downtime, recoverable data and operational dependencies.
From there, architecture decisions should be proportionate. Redundant networks, backup strategy, virtualization, monitoring and recovery plans should each solve a defined risk. The strongest environment is not the one with the most components—it is the one the organization can understand, operate and recover confidently.
Start with business impact
Classify workloads by criticality, define recovery objectives and test the recovery process. This creates a clear foundation for infrastructure investment.
