Read the first 7 IaaS, PaaS & SaaS Models flashcards as text
An enterprise runs its ERP system on a private cloud using virtual machines it fully controls. A third-party vendor hosts the VMs. Which model BEST describes this arrangement?
Answer: IaaS consumed via private cloud
When an enterprise controls its own VMs and applications hosted on someone else's physical infrastructure, it is consuming IaaS — even in a private cloud context.
Which cloud model requires customers to manage application performance tuning and query optimization?
Answer: PaaS and IaaS
In both PaaS and IaaS, customers deploy and manage their own applications and databases, making them responsible for performance tuning and query optimization.
Which of the following scenarios BEST illustrates a hybrid cloud approach combining IaaS and SaaS?
Answer: Running sensitive data on private IaaS while using cloud-based SaaS for email
A hybrid approach combines private IaaS for sensitive, controlled workloads with public SaaS for commodity functions like email, balancing control and convenience.
From a Total Cost of Ownership (TCO) perspective, which cloud model typically has the HIGHEST ongoing management labor costs for the customer?
Answer: IaaS
IaaS requires customers to manage OS patches, security configurations, middleware, and application stacks, resulting in the highest ongoing labor costs among cloud models.
A company wants to offer its customers a cloud-based accounting application that it built internally. What model are they acting as for their customers?
Answer: SaaS provider
When a company builds and delivers software to customers over the internet as a service, it is acting as a SaaS provider regardless of what cloud infrastructure it uses internally.
Which characteristic is SHARED by all three cloud service models (IaaS, PaaS, SaaS)?
Answer: Services are delivered over a network on demand
All three cloud service models share the fundamental characteristic of delivering IT resources over a network (internet or private) on demand.
A CCP exam candidate is asked to classify 'AWS Lambda' (serverless function execution). Which model is MOST appropriate?
Answer: PaaS, because the platform manages execution environment
Serverless computing like AWS Lambda is classified under PaaS because the provider manages all infrastructure and runtime, and developers only supply function code.
