Which option should an organization choose if there is a need to avoid software ownership?

Choosing Software as a Service (SaaS) is the optimal option for an organization that needs to avoid software ownership. SaaS provides software applications that are hosted and maintained by a service provider. This model allows organizations to access software over the internet on a subscription basis, eliminating the need to purchase, install, or manage the underlying infrastructure and software licenses. By using SaaS, organizations benefit from automatic updates, scaling, and support typically handled by the provider, which simplifies operations and IT responsibilities.

In contrast, the other options involve varying degrees of ownership or management of the software and infrastructure. For instance, Platform as a Service (PaaS) provides a platform for developers to build applications but still requires them to manage the applications they develop. Containers as a Service (CaaS) focuses on container orchestration, allowing more control over applications and their environments, which suggests a level of ownership and management. Infrastructure as a Service (IaaS) offers virtualized computing resources over the internet, meaning that organizations still need to manage the operating systems, applications, and data themselves, thus maintaining more ownership of the underlying software.
