Describing Cloud Computing Flashcards
(19 cards)
What is the fundamental definition of cloud computing?
Cloud computing is the on-demand delivery of compute services over the internet.
Name at least three types of compute services that are delivered via the cloud.
Types of compute services include compute, networking, storage, databases, and software.
What is considered the main advantage of using cloud computing?
The main advantage of the cloud is its flexibility to gain access to compute capacity instantly.
Explain the core concept of the shared responsibility model in cloud computing.
The shared responsibility model describes the separation of responsibility between a cloud vendor and a customer for different aspects of the cloud environment.
According to the shared responsibility model, what are customers always responsible for?
Customers are always responsible for their information and data, device security, and accounts and identities.
What are cloud providers always responsible for in the shared responsibility model?
Cloud providers are always responsible for all the physical assets like physical host, physical network, and physical data center access.
Describe the key characteristics of a private cloud.
A private cloud is essentially a cloud for a single customer, similar to an on-premises data center, which is not available to the general public.
What is a primary advantage of using a public cloud compared to a private cloud?
A primary advantage of a public cloud is its overall greater flexibility and the ability to pay for resources as you go.
How does a hybrid cloud combine elements of both public and private clouds?
A hybrid cloud combines public and private workloads, privately connecting them to offer the best of both worlds in terms of flexibility.
Differentiate between Capital Expenditures (CapEx) and Operational Expenditures (OpEx) in the context of cloud computing.
CapEx involves large, upfront investments requiring forecasting, while OpEx is a pay-as-you-go consumption model where you pay only for what you need right now.
What is Cloud Computing?
The on-demand delivery of compute services over the internet.
What are Compute Services?
A broad term encompassing services like compute, networking, storage, databases, and software delivered via the cloud.
What is the Shared Responsibility Model?
A framework that defines the division of responsibilities between a cloud vendor and a customer in a cloud environment.
What is a Private Cloud?
A cloud infrastructure dedicated to and operated exclusively for a single organization, not available to the general public.
What is a Public Cloud?
Cloud services offered by third-party providers over the public internet, available to anyone who wants to purchase them.
What is a Hybrid Cloud?
A cloud computing environment that uses a mix of on-premises, private cloud, and public cloud services with orchestration between the platforms.
What are Capital Expenditures (CapEx)?
Large, upfront investments in physical or intangible assets that are expensed over a period of years.
What are Operational Expenditures (OpEx)?
Ongoing costs for running a business, paid as you use a service or resource.
What is the Consumption Model?
Refers to the OpEx model in cloud computing where costs are based on the actual usage of resources (pay-as-you-go).
