In terms of cloud deployment models, the private model and the public model are on the opposite ends of the spectrum. Therefore, it's crucial to understand the difference between the two. If you know the strengths and drawbacks of each, then you can better decide on the best deployment model for a given use-case, even if it's something in between like the hybrid, community, or multicloud model!

Which of the following is classified as Private Model?

• Can get direct access to all the data centers.

• Provides an organization with exclusive use of infrastructure.

• In cloud bursting, overflow traffic is sent to this model.

• Usually has the least upfront time investment.

Answer explanation

Great job! One model isn't always better than the other so remember to consider your security requirements and other cloud deployment models in between.

Below are four statements each describing a deployment model and a use-case.

Select the statement that does not describe an appropriate use-case for a given model.

• Community model: Three different university hospitals have partnered on a research study requiring sensitive patient data.

• Public model: A young startup wants to get their app live right away at the lowest cost possible and with the ability to scale.

• Hybrid model: Different government agencies need access to tax data.

• Multicloud model: A freelance data scientist needs to use services from different cloud providers depending on their clients' needs.

Answer explanation

You got it! It's not clear in this use-case where the government agencies would benefit from combining more than one model. The community model sounds like a better fit for easier sharing of data, while maintaining exclusive use of the infrastructure.

GDPR has regulations on how long data can be stored. Below is an excerpt from the European Commission describing this regulation:

Data must be stored for the shortest time possible. That period should take into account the reasons why your company/organization needs to process the data, as well as any legal obligations to keep the data for a fixed period of time (for example national labour, tax or anti-fraud laws requiring you to keep personal data about your employees for a defined period, product warranty duration, etc.).

Your company/organization should establish time limits to erase or review the data stored.

How could this rule affect a company using cloud computing?

• If copies of European user data exist on multiple data centers, including disaster recovery backups, companies need to have a robust protocol for making sure every copy is deleted once the time limit elapses.

• Companies could store European user data outside of European Union borders to avoid having to delete data.

• Any hardware in data centers holding data that needs to be deleted will have to be physically destroyed, thereby increasing maintenance and hardware costs.

Answer explanation

Nice! Can you see how even regulations on time limits can affect a company's cloud infrastructure? These regulations hold true for both on-premise and cloud solutions. For on-premise solutions, you would have to make sure to delete all copies within your on-premise data centers.
