Cloud Architecture and Services

Cloud Architecture and Services defines both the structural design of cloud environments and the models through which they are delivered to users. The architecture is the blueprint that organizes and interconnects core components like compute, storage, and networking to ensure scalability, resilience, and security. This foundational structure supports the primary service models: Infrastructure as a Service (IaaS), which provides raw virtualized resources; Platform as a Service (PaaS), which offers a managed environment for developing and deploying applications; and Software as a Service (SaaS), which delivers complete, ready-to-use software over the internet.
