A company wants to migrate its data and applications to the cloud to improve scalability and reduce operational costs. Which type of cloud computing model should they consider?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
For scalability and reduced operational costs, a Platform as a Service (PaaS) model is suitable as it provides a platform to develop, run, and manage applications without the complexity of infrastructure management.
