Heterogeneous stacks, ransomware, and ITaaS: A DR nightmare

The document argues that ransomware has become a leading cause of outages and that heterogeneous, ITaaS-heavy environments complicate disaster recovery, urging organizations to standardize infrastructure, maintain immutable backups, and rigorously test failover/failback. Using recent healthcare sector incidents—such as the Synnovis/Qilin attack affecting NHS services, outages tied to Octapharma/OneBlood, and the Change Healthcare breach—it highlights cascading third‑party risks and the need to verify (not just trust) suppliers’ DR capabilities. It notes that DRaaS offerings can help but often require homogeneous, well‑protected workloads and careful configuration, underscoring shared responsibility and proactive planning.
