Explanation

SaaS – Software as a Service

Option A (SaaS) is correct because the provider manages everything - hardware, operating system, software, patching, and monitoring - while Heather's only responsibility is managing user accounts. This is the defining characteristic of SaaS: the customer simply uses the application, with virtually no infrastructure or software maintenance responsibilities.

The distractors are wrong because:

• IaaS (Infrastructure as a Service) only provides virtualized hardware/infrastructure; the customer must manage the OS, middleware, and applications themselves.
• CaaS (Containers as a Service) provides a platform for deploying and managing containerized applications, requiring significantly more technical administration from the customer.
• PaaS (Platform as a Service) sits between IaaS and SaaS - the provider manages the infrastructure and OS, but the customer is responsible for deploying and managing their own applications.

Memory tip: Think of SaaS as "Software as a Subscription" - if you just log in and use it like Gmail or Salesforce with no backend responsibilities, it's SaaS. A helpful hierarchy to remember is IaaS → PaaS → SaaS, where each step up means the provider takes on more responsibility and you manage less.
