4.1 - Cloud Characteristics Flashcards
What is an internal cloud?
An internal cloud is a cloud infrastructure created on an organization’s own internal network, using their own data center, equipment, and resources.
What are the cost characteristics of an internal cloud?
Initial costs are high due to the need to acquire equipment, but there are no ongoing costs associated with usage. You can use as much or as little as needed without additional fees.
What is an external cloud?
An external cloud is a cloud infrastructure provided by third-party cloud providers like Amazon or Microsoft, where resources are shared and managed by the provider.
What is metered cloud service?
Metered cloud service refers to a billing model where you pay based on the amount of platform usage, such as data transfer, storage, or computing power.
What is a non-metered cloud service?
A non-metered cloud service charges a fixed cost regardless of usage, allowing unlimited use of certain services for a flat monthly fee.
What is rapid elasticity in cloud computing?
Rapid elasticity is the ability to dynamically scale resources up or down as needed, allowing for flexible and efficient handling of changing workloads.
What does high availability mean in a cloud-based platform?
High availability refers to the built-in redundancy of cloud platforms that ensures continuous operation even if there are infrastructure failures, such as power loss or network issues.
Why is file synchronization important in a cloud environment?
File synchronization is important to ensure data consistency across multiple cloud instances deployed in different data centers or geographic locations.
What is Desktop as a Service (DaaS)?
Desktop as a Service (DaaS) is a cloud service that delivers virtual desktops to end users over the internet, allowing access to a full desktop environment from any device.
What is Virtual Desktop Infrastructure (VDI)?
Virtual Desktop Infrastructure (VDI) refers to the hosting of desktop environments on virtual machines, typically provided in a cloud-based DaaS solution.
What is required to access a cloud-based desktop in DaaS?
You need a device with a screen, a keyboard, and a mouse, along with a network connection to access the cloud-based desktop.
Why is network connection important for Desktop as a Service?
A network connection is essential for DaaS as it enables the remote desktop view of the cloud-based environment, transmitting minimal data between the client and the desktop.
What is Amazon’s DaaS offering called?
Amazon’s Desktop as a Service offering is called Amazon Workspaces.
What are some advantages of cloud-based application instances?
Advantages include rapid elasticity for scaling, high availability for redundancy, and global synchronization for data consistency.
What is the main difference between internal and external cloud costs?
Internal cloud has high initial costs with no ongoing usage fees, while external cloud costs vary based on usage and provider billing models.
