You have a business relationship with a cloud provider for all sales management functionality. Through the APIs and SDKs, you have customized the interface and some functionality, but the back end service is done through the cloud provider. In this relationship, which service is completed by the cloud provider?
In the given scenario, the primary aspect is that the entire sales management functionality is provided by the cloud provider, while customization is done via APIs and SDKs. This aligns with the Software-as-a-Service (SaaS) model, where a cloud provider hosts both the application and the data, and end-users can access the service over the internet. The customization of the interface and some functionality does not change the fact that the core application is a service provided by the cloud provider, making SaaS the correct answer.
B. Platform-as-a-service (PaaS) In the described scenario, where you have a business relationship with a cloud provider and you are customizing the interface and functionality through APIs and SDKs while relying on the cloud provider's back-end service, the service model is Platform-as-a-Service (PaaS). In a PaaS model, the cloud provider offers a platform that allows you to develop, deploy, and manage applications while handling the underlying infrastructure, including servers, storage, and networking. You are responsible for customizing the applications and their functionality, while the cloud provider takes care of the platform and infrastructure.
