Episode 63 — Understand Cloud Deployment and Service Models Clearly

Cloud topics appear across SSCP domains, and clarity on models is essential. We define deployment models—public, private, community, and hybrid—and service models—Infrastructure as a Service, Platform as a Service, and Software as a Service. You’ll learn what the customer manages versus the provider in each, how elasticity and multitenancy affect risk, and why identity, logging, and network design change in virtualized contexts. We connect models to common exam stems: selecting where to place controls such as encryption, key management, security groups, and web application protection, and recognizing when provider features replace on-prem tools.

We then apply the taxonomy to concrete design and validation steps. Examples include mapping shared network controls to cloud security groups and route tables, using platform services for secrets and configuration, and understanding SaaS limitations where only identity, data classification, and DLP are customer-side levers. We discuss evidence for assurance—configuration exports, access logs, resource tags, and architecture diagrams—and pitfalls such as flat address spaces, unmanaged admin APIs, and drift between templates and running stacks. Troubleshooting highlights include misaligned regions and zones, ephemeral assets without inventory, and overlooked control plane paths. With a crisp model of who operates which layer and how evidence is produced, you will choose exam answers that fit the stated cloud context rather than assuming on-prem patterns still apply.
