Which of the following is a term used to describe the collection of cloud computing services provided to users?

The term "cloud offerings" accurately describes the collection of cloud computing services provided to users. It encompasses the various services and products available in the cloud, including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). This terminology is frequently used in the industry to categorize and communicate the diverse range of services that cloud service providers deliver to meet different business needs and objectives.

The other terms, while relevant to cloud computing, do not specifically encapsulate the entirety of services provided. "Cloud ecosystem" suggests a broader network of interactions and dependencies among various cloud providers and users but does not directly refer to the services themselves. "Cloud infrastructure" is focused on the foundational components such as servers, storage, and networking, rather than the array of services offered. "Cloud solutions" typically refers to specific applications or methodologies developed to solve problems using cloud technologies, which may not represent the full spectrum of available services. Thus, "cloud offerings" is the most precise term for what is being described.
