4.1 Cloud Deployment Models Flashcards
What is a public cloud?
Resources provided over the internet by third-party service providers, offering cost efficiency and quick scalability.
What is a private cloud?
A cloud exclusively built and managed for a single organization, prioritizing security over cost.
What is a hybrid cloud?
A deployment model combining public and private clouds, ensuring sensitive data remains secure with strict data hosting policies.
What is a community cloud?
A shared resource model for organizations with common needs (e.g., healthcare or research groups) to reduce costs.
What is multitenancy in cloud computing?
A model where multiple organizations share the same resources, balancing efficiency and cost with potential shared security risks.
What is single tenancy in cloud computing?
A model where resources are dedicated to one organization, providing enhanced security at a higher cost.
Which cloud model is ideal for cost-driven organizations?
Public cloud or multitenancy models.
Which cloud model is best for security-centric organizations?
Private or single-tenancy models.
What is the main benefit of a public cloud?
Cost efficiency and scalability.
What is the primary drawback of a private cloud?
Higher costs compared to public or multitenant clouds.
Why is hybrid cloud considered a balanced approach?
It combines the benefits of public and private clouds while ensuring sensitive data is secure.
What organizations commonly use community clouds?
Groups with shared needs like healthcare, education, or research sectors.
What is a key risk of multitenancy?
Collateral damage from attacks or misuse by other tenants sharing the same resources.
How does single tenancy improve security?
By dedicating resources to one organization, eliminating risks from other tenants.
