Cloud Security Architecture

Cloud security architecture is the design of security controls, trust boundaries, and data flows within cloud-based systems to protect against threats while enabling business requirements. It encompasses network segmentation design (VPC topology, subnet zoning), identity architecture (federation, workload identity, privilege design), data protection (encryption key hierarchy, data classification), and detective controls (logging strategy, threat detection coverage).

Architecture reviews before cloud adoption decisions are significantly more cost-effective than remediating production security gaps.
