C. Software as a service (SaaS).
Software as a Service (SaaS) provides fully managed software applications that users can access directly over the internet, without the need to manage servers, infrastructure, or write code. The cloud vendor takes care of everything, including updates, security, and maintenance. Examples include Gmail, Microsoft 365, and Salesforce.
Incorrect options:
A. Infrastructure as a service (IaaS): Provides virtualized computing resources like virtual machines, storage, and networking. With IaaS, users still need to manage and configure the operating systems, applications, and code on top of the infrastructure (e.g., Google Compute Engine or AWS EC2). This is not the right fit because the organization would still be responsible for managing the software and services.
B. Platform as a service (PaaS): Provides a platform for developers to build, deploy, and manage applications without dealing with the underlying infrastructure. However, users still need to write their own code and configure the platform (e.g., Google App Engine or AWS Elastic Beanstalk). This is not the right fit because the organization does not want to manage code.
D. Functions as a service (FaaS): Allows users to execute code in response to events without managing servers. This is a more granular service model where users write functions, and the cloud platform executes them. However, this still involves writing code, so it's not the correct fit for someone who wants to use a software application without managing any code.
