Which of the following is a cloud service model that organizations use when their third-party ERP tool is provided as a complete service?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
The correct answer is B. SaaS (Software-as-a-Service).
SaaS is a cloud service model where a third-party provider hosts applications and makes them available to customers over the internet. In this model, customers do not need to install or manage the software themselves, as the provider handles maintenance, updates, and security. Customers typically access the software through a web browser or a dedicated application, and pay for the service based on usage or subscription.
In the context of the question, the third-party ERP (Enterprise Resource Planning) tool is provided as a complete service, which means that it is likely hosted by a SaaS provider. This allows organizations to leverage the benefits of cloud computing, such as scalability, flexibility, and cost-efficiency, without having to manage the underlying infrastructure or software.
The other options are:
A. Public cloud: This refers to a cloud computing model where services and resources are offered over the public internet, typically by a third-party provider. Public cloud services can be accessed by anyone with an internet connection, and are often offered on a pay-as-you-go or subscription basis.
C. Hybrid cloud: This refers to a cloud computing environment that combines public and private cloud resources, allowing organizations to take advantage of the benefits of both. Hybrid cloud architectures can be complex and require careful planning and management.
D. IaaS: This stands for Infrastructure-as-a-Service, which is a cloud service model that provides virtualized computing resources over the internet. In an IaaS model, customers have more control over the underlying infrastructure than in a SaaS model, but are still responsible for managing their own applications and data.
