Which cloud service model is most suitable for deploying code directly in the cloud without the need for additional infrastructure?

• A. Infrastructure as a Service (IaaS)
• B. Platform as a Service (PaaS)
• C. Software as a Service (SaaS)
• D. Network as a Service (NaaS)

Answer: (B)

The most suitable cloud service model for deploying code directly in the cloud without the need for additional infrastructure is Platform as a Service (PaaS). PaaS provides a development and deployment environment in the cloud, allowing developers to focus on writing code rather than managing the underlying hardware and software layers. PaaS includes a variety of tools and services that support the entire application lifecycle, including development, testing, and deployment. This model abstracts much of the complexity involved in managing servers, storage, and networking, which are typically handled by the PaaS provider. Developers can easily deploy their applications and scale them according to demand, taking advantage of built-in services such as databases, caching, and messaging systems, all without needing to provision underlying infrastructure. This contrasts with other models such as IaaS, which requires users to manage virtual machines and networking resources, making it less convenient for quick code deployments. SaaS delivers fully managed applications to end users, which does not involve code deployment by developers themselves. Network as a Service (NaaS) focuses primarily on providing network services, thus is not applicable for deploying applications. In summary, PaaS is designed specifically to facilitate the development and deployment of applications in a cloud environment, making it the most
