Cloud computing models Flashcards
What is a cloud deployment model?
A cloud deployment model defines where your data is stored and how your customers interact with it. In
other words, how do they get to it, and where do the applications run? It also depends on how much of
your infrastructure you want or needs to manage.
What is a public cloud?
In the public cloud model, you have no local hardware to manage or keep up-to-date—everything runs on your cloud service provider’s hardware. This means that
the information technology infrastructure (hardware, servers, software, and other infrastructure items) is
located somewhere other than your data center, and is managed by a third party.
What are the two variants of a public cloud?
Shared public cloud and Dedicated public cloud.
What is a shared public cloud?
is where many companies share common resources (such as email) within the
same cloud service provider’s environment. Each company is only aware of its cloud services
account (also known as a tenant); only the cloud service provider who manages this multi-tenant
the environment is aware of the different accounts running within the same cloud. This model works well
for smaller businesses who are looking to save additional costs because sharing computing resources with other cloud users is cheaper than reserving resources for a single account.
What is a dedicated public cloud?
is typically for enterprise organizations who require a dedicated physical infrastructure that is reserved for only their use. While the cost might be higher than that of the shared public cloud, the dedicated public cloud might offer better security, performance, and customization.
What is a private cloud?
In a private cloud, you create a cloud environment in your own data center and provide self-service access
to compute resources to users in your organization. This model offers a simulation of a public cloud to
your users, but you remain entirely responsible for the purchase and maintenance of the hardware and
software services you provide
What are some of the reasons to move away from private cloud?
You have to purchase the hardware for startup and maintenance.
Private clouds require IT skills and expertise that can be hard to find.
What is a hybrid cloud?
A hybrid cloud combines public and private clouds, allowing you to run your applications in the most
appropriate location. For example, you could host a website in the public cloud, but link it to a highly
secure database hosted in your private cloud (or on-premises data center).
Reasons why you won’t put some data on the cloud.
Sensitive data, Extend capabilities of on-premises systems, Reduce data protection costs,
