A hyperscaler is a very large cloud provider that runs enormous, elastic infrastructure across multiple regions and data centers. These platforms are built to add compute, storage, and networking capacity quickly, often for millions of customers and services at once. In practice, hyperscalers include the major public cloud ecosystems that support on-demand scaling, managed databases, identity services, and global content delivery.
In cyber security, hyperscalers matter because they concentrate both opportunity and risk. Defenders use them for resilience, rapid patching, centralized logging, and multi-region failover. Attackers target them indirectly through stolen credentials, misconfigured storage, weak API keys, or abused cloud identities, because one account or workload can expose large amounts of data. Their scale also means a security mistake can spread widely if policies, permissions, or automation are poorly controlled. Good defense depends on strong identity management, least privilege, network segmentation, and continuous configuration monitoring.
