Commonly Used Concept by Cloud Provider

A.

A limit puts a maximum value on the amount of resources that may be consumed by either a system, a service, or a cloud customer.

It is commonly used to prevent one entity from consuming enormous amounts of resources and having an operational impact on other tenants within the same cloud system.

Limits can either be hard or somewhat flexible, meaning a customer can borrow from other customers while still having their actual limit preserved.

A reservation is a guarantee to a cloud customer that a certain level of resources will always be available to them, regardless of what operational demands are currently placed on the cloud environment.

Both cap and throttle are terms that sound similar to limit, but they are not the correct terms in this case.

Cloud providers use a variety of techniques to prevent cloud customers from consuming excessive resources that could negatively impact other customers in the cloud environment. One of the most common techniques used is resource throttling.

Resource throttling is a process that limits the amount of resources that a customer can consume within a cloud environment. This is typically done by setting usage limits or quotas on various resources such as CPU usage, memory, network bandwidth, and storage.

For example, a cloud provider might set a limit on the amount of CPU usage that a customer can consume in a given period. If the customer exceeds this limit, the cloud provider will throttle their usage, which means that their access to CPU resources will be reduced or temporarily suspended.

Resource throttling is an important concept in cloud computing because it helps to ensure that all customers are able to access the resources they need to run their applications and services without being impacted by other customers who may be consuming excessive amounts of resources.

In contrast to resource throttling, resource reservation involves allocating specific resources to a customer for their exclusive use. This can be useful in scenarios where a customer needs to guarantee a certain level of performance or availability for their application or service. However, resource reservation is less common than resource throttling in cloud computing environments.

In summary, the concept commonly used by a cloud provider to prevent cloud customers from potentially consuming enormous amounts of resources within a cloud environment and thus having a negative impact on other customers is resource throttling.
