Question
An organization developed a containerized application. The organization wants to run the application in the cloud and automatically scale it based on demand. The security operations team would like to use container orchestration but does not want to assume patching responsibilities. Which of the following service models best meets these requirements?
A. PaaS
B. SaaS
C. IaaS
D. MaaS
Answer
A. Platform as a Service (PaaS) is the best cloud service model for this scenario.
Explanation
PaaS provides a managed platform for developing, running, and scaling applications without the operational overhead of managing the underlying infrastructure. With PaaS, the cloud provider handles patching, updates, and maintenance of the operating system, middleware, and other platform components. This allows the organization’s security team to leverage container orchestration capabilities for their application while the cloud provider takes care of the patching.
PaaS supports containerized applications and can automatically scale them based on demand, meeting the organization’s scalability requirements. The development team can focus on building the application using the programming languages, libraries, and tools supported by the PaaS platform.
In contrast:
- Software as a Service (SaaS) provides access to a fully managed application, which would not allow custom application development.
- Infrastructure as a Service (IaaS) only provides the virtual machines and requires the organization to manage the operating system, middleware, and runtime environment, including patching.
- Metal as a Service (MaaS) refers to bare metal servers and is not a standard cloud service model for running applications.
Therefore, PaaS provides the ideal balance of a managed platform for running containerized applications while allowing the organization to avoid patching responsibilities, making it the best choice for this scenario.
