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

An organization is deploying a new web application using a Platform as a Service (PaaS) cloud model. Which of the following operational layers are managed directly by the cloud service provider in this service model? (Select TWO.)

  1. Operating system updates and security patchesCevap
  2. B
    Custom application source code and business logic
  3. Physical server hardware and virtualization layerCevap
  4. D
    Customer user accounts and application data management

Cevap

In a Platform as a Service (PaaS) environment, the provider handles operating system patching and physical hardware infrastructure, while the customer maintains control over custom code and data.
In Platform as a Service (PaaS), the cloud vendor provides a fully managed runtime environment. This includes servicing the underlying physical hardware, virtualized hypervisors, and operating system maintenance. The developer/customer is only responsible for writing application code and managing datasets.

Adım Adım Çözüm

1
Identify the requested cloud service model
The scenario specifies Platform as a Service (PaaS).
Different service models divide customer vs. provider responsibilities at different architectural layers.
2
Differentiate shared responsibility boundaries for PaaS
PaaS providers supply the runtime environment, middleware, operating systems, hypervisors, and physical hardware. Customers supply application code and user data.
PaaS frees developers from managing OS configurations and server hardware.
3
Select matching provider responsibilities
Operating system updates and physical server infrastructure are provider responsibilities.
These match the platform and infrastructure management tier managed by the vendor.
