Zorluk: OrtaPlatform as a Service (PaaS)

A financial startup is deploying a custom database backend for a new mobile transaction application. The development team wants to focus exclusively on designing the database schema and writing stored procedures, without managing hardware maintenance, operating system patching, or database engine updates.

Which service model and responsibility division meets these requirements?

  1. Platform as a Service (PaaS), where the cloud provider manages the operating system patching and database engine updates.Cevap
  2. B
    Platform as a Service (PaaS), where the customer is responsible for operating system patching and database engine updates.
  3. C
    Infrastructure as a Service (IaaS), where the cloud provider manages the operating system patching and database engine updates.
  4. D
    Software as a Service (SaaS), where the cloud provider manages the database schema design and stored procedures.

Cevap

Platform as a Service (PaaS), where the cloud provider manages the operating system patching and database engine updates.
The correct option is 'Platform as a Service (PaaS), where the cloud provider manages the operating system patching and database engine updates.' This service model allows the customer to focus on application development and database design (like schemas and stored procedures) while the cloud provider handles the underlying infrastructure, operating system, and database software updates.

Adım Adım Çözüm

1
Analyze the management requirements of the financial startup.
The startup needs custom database access (schema design, stored procedures) but wants to delegate hardware, OS patching, and database engine updates to the cloud provider.
Identifying what the customer wants to manage versus what they want the provider to manage helps determine the correct cloud service model.
2
Evaluate the cloud service models (IaaS, PaaS, SaaS) against these requirements.
IaaS leaves OS and database engine management to the customer. SaaS does not allow custom database schema design. PaaS allows custom database configurations while the provider manages the OS and database engine.
Comparing requirements to the features of each service model narrows the choices down to Platform as a Service (PaaS).
3
Determine the correct responsibility distribution for the chosen PaaS model.
In PaaS, the cloud provider manages the operating system patching and database engine updates, not the customer.
This filters out the incorrect PaaS option that misassigns OS patching to the customer.
