A solutions engineer is looking for a cloud model owned primarily by the organization they work for, but the engineer also wants to reduce costs where possible. What solution would most likely fit the engineer's organizational needs?

The correct choice for this scenario is a community cloud model. A community cloud is specifically designed for a collection of organizations that share common interests, such as security requirements, compliance considerations, or specific applications. By utilizing a community cloud, the solutions engineer can benefit from shared resources and costs among the participating organizations, which helps in reducing expenses while still maintaining ownership and control over the infrastructure.

Organizations that might face similar challenges or have related missions can collaboratively benefit from the cost savings presented in a community cloud. This model aligns with the engineer's goals of having a cloud environment that is primarily owned by their organization while also being mindful of cost reductions through shared services and resources.

In contrast, a private cloud would mean that the organization has a dedicated cloud solely for their use, which can become more expensive as all costs fall on the single organization. A public cloud, while potentially more cost-effective due to its scale and resource sharing with the general public, would not meet the ownership requirements. The multi-tenant model typically refers to a scenario present in public clouds where multiple customers share the same physical infrastructure, leading to a lack of control and possibly security concerns that a single organization would want to avoid. Hence, the community cloud offers the best balance of ownership and cost efficiency
