Cloud Computing Concepts

These flashcards cover essential concepts related to cloud computing, including service models, resource management strategies, and deployment types.

What is resource pooling in cloud services?

Resource pooling is when a Cloud Service Provider (CSP) pools resources in a multi-tenant model and adjusts resource allocation on an on-demand basis.

What does on-demand self-service mean in cloud computing?

On-demand self-service allows cloud services consumers to provision services as needed without directly interacting with the Cloud Service Provider (CSP).

What is measured service in cloud computing?

Measured service refers to the metering of resource utilization by Cloud Service Providers (CSP), allowing for efficient resource allocation and accurate billing based on consumption.

What is meant by broad network access in the context of cloud services?

Broad network access means that client devices and traditional server deployments can access cloud-based resources across the network.

Define elasticity in cloud computing.

Elasticity refers to the dynamic allocation of resources in cloud computing, enabling more efficient utilization of those resources.

What does scale-up mean in cloud resource management?

Scale-up means to add more resources to the existing deployment, such as increasing RAM in a server.

What is right-sizing in relation to cloud services?

Right-sizing is managing the resources available to each virtual machine on a cloud server based on its needs.

Explain scale-out in cloud computing.

Scale-out refers to adding more resources in a distributed environment, such as adding more web servers to support increased traffic.

What does auto-scaling do?

Auto-scaling automatically manages the number of active servers in a deployment based on workload, helping organizations manage costs effectively.

What is Platform as a Service (PaaS)?

PaaS provides hardware, operating systems, and necessary tools to consumers, who manage their data using those tools.

Define Software as a Service (SaaS).

SaaS solutions provide access to software services, with the Cloud Service Provider (CSP) being responsible for cloud management.

What is Infrastructure as a Service (IaaS)?

IaaS offloads hardware support to the Cloud Service Provider (CSP), while consumers manage virtual machines and software.

When might a private cloud be necessary?

A private cloud may be necessary for security concerns due to industry regulations, government requirements, or insurance limitations.

What are the characteristics of a community cloud?

A community cloud serves a specific group of consumers with similar business or security needs and restricts access to its members.

What is a hybrid cloud model?

A hybrid cloud model combines elements of public, private, and community clouds, providing adaptable security levels.
