What cloud service model is preferred by a software development company with no infrastructure requirements?

1. PaaS

2. SaaS

3. IaaS

4. XaaS

The correct answer is: PaaS

The preferred cloud service model for a software development company with no infrastructure requirements is Platform as a Service (PaaS). This model provides a cloud platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure. Essentially, PaaS offers an environment that includes everything needed for software development, such as runtime, development tools, databases, and middleware. In this scenario, PaaS is ideal because it abstracts away the complexities of server management, storage, and networking, which are typically associated with infrastructure. Instead, developers can focus on coding and application development, utilizing the built-in tools and services provided by the PaaS provider. Other options like Software as a Service (SaaS) deliver fully functional applications over the internet but do not allow for customization or application development, making it less suitable for a development-centric organization. Infrastructure as a Service (IaaS) provides raw computing resources like virtual machines and storage, which would require management and setup that the company seeks to avoid. XaaS refers to the broader concept of everything as a service, encompassing various service models, but it does not specifically cater to the needs of software development in the same way that PaaS does.
