CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingMedium
A company is evaluating different cloud deployment models. They require a solution that offers the scalability and cost-effectiveness of public cloud resources for non-sensitive data and general applications, while keeping highly sensitive data and critical core applications on their existing on-premises infrastructure. What cloud deployment model would best meet these requirements?
- AHybrid cloud
- BPublic cloud
- CPrivate cloud
- DCommunity cloud
Show answer & explanationAnswer & explanation
Correct answer: A. Hybrid cloud
A hybrid cloud model combines a private cloud (on-premises infrastructure) with a public cloud, allowing organizations to leverage the benefits of both. This setup enables them to keep sensitive data and critical applications secure on-premises while using the public cloud for scalable, less sensitive workloads, exactly matching the company's needs.
Why the other options are wrong
- B. Public cloud alone would not meet the requirement for keeping sensitive data on-premises.
- C. Private cloud alone would not provide the scalability and cost-effectiveness of public cloud for non-sensitive data.
- D. Community cloud is shared by several organizations with common concerns, not a mix of public and private for a single organization.
Hybrid Cloud
A cloud computing deployment model that combines two or more distinct cloud infrastructures (private, public, or community) that remain unique entities but are bound together by standardized or proprietary technology.
- Combines private and public cloud.
- Allows data and applications to be placed based on sensitivity and need.
- Offers flexibility and scalability.
Memory trick: A 'HYBRID' cloud is half in your house, half in the public sky.
