Your company has a Cloud computing deployment model that uses a private Cloud, which has
sufficient resources for most anticipated workloads.
You are asked to explore possibilities for coping with unexpected peak demands where the
resources in the private Cloud are fully utilized.
Your proposal must conform to the National Institute of Standards and Technology (MST)
standards to be acceptable.
Which solution would you recommend?
A.
Use a hybrid Cloud that uses capacity from another private Cloud from the same organization
during peak periods.
B.
Use a hybrid Cloud that uses capacity from a community Cloud during peak periods.
C.
Use a hybrid Cloud that uses capacity from another private Cloud from a different organization
during peak periods.
D.
Use a hybrid Cloud that uses capacity from a public Cloud during peak periods.
Explanation:
I think so!
Cloud Computing: Deployment Models
Private: For exclusive use by a single organization
Community: A common environment for use by a group of related organizations
Public: Separate environments for use by multiple organizations (multi-tenancy)
Hybrid: A combination of private and public clouds for a single organization
Deployment Models: Hybrid Cloud
A combination of two or more private, community, or public clouds
Clouds remain distinct.
Three use-cases:
Lifecycle distribution
Functional distribution
Workload distribution — aka “cloud bursting”
Four Cloud Computing Deployment Models
The NIST definition of cloud computing includes four deployment models:
…
Hybrid Cloud: This may be to implement a “cloud bursting” scenario, where an organization might run the steady-state workload of an application on a private cloud. But when a spike in workload occurs (such as at the end of the financial quarter or during the holiday season), the application can burst out to use computing capacity from a public cloud, and then return those resources to the public pool when they are no longer needed.
Hybrid Cloud for Total Flexibility
The hybrid cloud deployment model involves two or more private, community, or public clouds that are separate entities but are bound by common technologies. These common technologies allow applications to scale, migrate, or communicate between the clouds.
Three use-cases for implementing a hybrid cloud deployment model are:
Lifecycle distribution: Your organization may be developing its own application, but does not wish to own and maintain a development environment including source code control system, development platform, and other development resources. An example of the hybrid cloud model would be using resources in a public cloud to develop and test code, which is then deployed to an internal private cloud where your production environment is running.
Functional distribution: Your organization may have a business process such as an insurance claim workflow where some client interaction is unregulated but for regulatory or privacy compliance part of the process needs to be strictly controlled and monitored. The hybrid cloud model allows you to take advantage of the benefits of a public SaaS cloud while ensuring regulatory compliance by protecting sensitive operations and information in your internal private cloud.
