Episode 97: Platform Diversity and Multi-cloud Architecture (Domain 3)

Relying on a single technology stack or vendor can introduce systemic risk, and in this episode, we explore how platform diversity and multi-cloud strategies enhance both security and resilience. Platform diversity means using a range of operating systems, software solutions, or infrastructure types to avoid monocultures that attackers can exploit with a single technique. If every system uses the same OS or hypervisor, a single vulnerability could compromise your entire environment. Multi-cloud architecture, on the other hand, spreads workloads across different cloud providers—such as AWS, Azure, or Google Cloud—to mitigate outages, reduce vendor lock-in, and support regulatory compliance through regional customization. We also discuss how diversity increases operational complexity, requiring consistent visibility, unified policy enforcement, and cross-platform monitoring. Still, for organizations with critical uptime or high-value assets, diversity provides both defense in depth and business continuity. It’s not about being everywhere—it’s about not being entirely dependent on any one thing.
