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

A game development studio is migrating its backend API services to a Platform as a Service (PaaS) solution to streamline software deployment. Under the cloud shared responsibility model for PaaS, which of the following tasks remain the direct responsibility of the studio's development and operations team? (Select TWO.)

  1. Developing, deploying, and maintaining the custom application source codeCevap
  2. B
    Installing security updates and patches on the underlying host operating system
  3. Managing application database schemas and user access permissionsCevap
  4. D
    Provisioning physical server hardware and configuring hypervisor virtual networks

Cevap

The studio's team remains responsible for developing, deploying, and maintaining the custom application source code, as well as managing application database schemas and user access permissions.
Under Platform as a Service (PaaS), the cloud vendor manages the underlying physical host infrastructure, virtualization hypervisor, and operating system platform. The customer retains administrative control and responsibility strictly over the application layer (writing, deploying, and updating source code) and the data layer (defining database schemas and configuring user access control).

Adım Adım Çözüm

1
Identify the cloud service model specified in the scenario.
The scenario describes Platform as a Service (PaaS).
Understanding the service model determines the division of responsibility between the cloud provider and the enterprise customer.
2
Determine the customer administrative boundaries for PaaS.
In PaaS, the provider handles infrastructure hardware, hypervisors, runtime environments, and operating systems, leaving the customer in charge of application code and data.
PaaS abstracts away low-level system management so developers can focus solely on software creation and data governance.
3
Evaluate the choices against PaaS customer responsibilities.
Application code deployment and database schema/access configuration belong to the customer. Host OS patching and hypervisor/hardware provisioning belong to the provider.
Managing OS patches is an IaaS responsibility, while physical server maintenance is managed by the vendor in all public cloud service models.
