Zorluk: ZorCloud Service Models (IaaS, PaaS, SaaS)

A logistics company is containerizing its fleet routing API microservices. The systems engineering team wants a cloud deployment where the cloud service provider maintains the physical hardware, virtualization layer, operating system kernels, and language runtime environment. However, the company's developers need to deploy custom code, configure API endpoints, and manage application database tables without taking on OS patching or hypervisor administration duties. Which cloud service model best fulfills these deployment and management requirements?

  1. A
    Infrastructure as a Service (IaaS)
  2. Platform as a Service (PaaS)Cevap
  3. C
    Software as a Service (SaaS)
  4. D
    Desktop as a Service (DaaS)

Cevap

Platform as a Service (PaaS)
Platform as a Service (PaaS) provides a pre-configured platform and execution runtime where the cloud vendor manages hardware infrastructure, virtualization, operating systems, and runtime engines. This matches the company's requirement for developers to deploy API microservices and manage database structures without having to maintain OS kernels or hypervisor software.

Adım Adım Çözüm

1
Analyze the management boundary requirements in the scenario.
The vendor must manage host hardware, hypervisors, OS maintenance, and language runtimes, while developers maintain application code and database schemas.
Evaluating shared responsibility boundaries for OS and runtime management distinguishes IaaS, PaaS, and SaaS.
2
Compare the scope against standard cloud service model definitions.
Platform as a Service (PaaS) delivers hardware, OS, and runtime infrastructure as a service, allowing users to deploy applications without managing underlying software platforms.
PaaS abstracts operating system administration and hardware maintenance while offering deployment control to developers.
3
Eliminate non-matching cloud models.
IaaS requires the customer to manage OS patching; SaaS removes code-level developer control; DaaS provides end-user virtual desktops.
Only PaaS satisfies both constraints of zero OS management and full application code control.
