Cloud Agnostic

1. Explain how the concepts of scalability and elasticity differ in cloud computing and provide an example of each.
2. Given a scenario where an organization needs to rapidly scale its infrastructure up and down based on demand, which cloud service model (IaaS, PaaS, SaaS) would be most appropriate and why?
3. Describe a use case where a hybrid cloud model would be more advantageous than relying solely on public or private cloud models. Include considerations of compliance, data sovereignty, and technological flexibility in your answer.
4. Explain how serverless computing changes the cost model for running cloud-native applications compared to traditional cloud service models. Provide an example of a use case where serverless computing would significantly reduce operational costs.
5. Differentiate between a virtual network in a cloud environment and a traditional network. How does a virtual network facilitate the implementation of a hybrid cloud model?
