Which cloud service model is typically chosen by software development teams that want to avoid managing the underlying infrastructure?

• A. PaaS
• B. SaaS
• C. IaaS
• D. XaaS

Answer: (A)

Platform as a Service is the option that lets development teams focus on building and deploying their applications while the provider handles the underlying infrastructure, including servers, operating systems, middleware, and runtime environments. With PaaS, you get tools, deployment pipelines, and scalable runtime environments managed for you, so you don’t have to worry about provisioning or maintaining the hardware or OS. You still control your application code and data, but the heavy lifting of infrastructure management is offloaded to the cloud provider. If you wanted a fully ready-to-use software experience, Software as a Service would be the path, where you consume an application without managing any part of its stack. Infrastructure as a Service would leave you responsible for configuring and maintaining the operating system, middleware, and runtime on virtual machines, which is the opposite of the goal here. XaaS is a broad, catch-all term for any service delivered over the cloud and isn’t the specific model that targets reducing infrastructure maintenance for development teams.
