Zorluk: ZorCloud Models (Public, Private, Hybrid, Multi-cloud)

A company is planning its cloud migration strategy and establishes the following requirements:

* The legacy customer database must remain in the company's local datacenter to ensure physical control and data sovereignty.
* New web applications must be deployed to an environment where the hardware is owned and maintained by a third-party cloud provider, and paid for as an operational expense (OpEx).
* The web applications must securely access data from the legacy customer database.

Which cloud model should the company adopt to satisfy these requirements?

  1. A
    Public cloud
  2. B
    Private cloud
  3. Hybrid cloudCevap
  4. D
    Software as a Service (SaaS)

Cevap

Hybrid cloud
The correct answer is hybrid cloud. A hybrid cloud combines public cloud services (such as hosting web applications on a third-party cloud provider's hardware using an OpEx model) with private cloud or on-premises infrastructure (such as keeping a database in a local datacenter to maintain data sovereignty and physical control). This allows the two environments to communicate and share data securely, meeting all of the company's requirements.

Adım Adım Çözüm

1
Analyze the requirement for the legacy customer database.
The database must remain in the local datacenter for physical control and data sovereignty, representing a private cloud or on-premises environment.
Identifying the infrastructure environment of the database is the first step in determining the overall model.
2
Analyze the requirement for the new web applications.
The applications must run on hardware owned/maintained by a third-party provider under an OpEx cost structure, representing a public cloud environment.
Identifying the infrastructure environment of the web applications provides the second component of the overall model.
3
Determine the combined cloud model that integrates both environments.
Combining an on-premises/private cloud environment (for the database) with a public cloud environment (for the web apps) is the definition of a hybrid cloud.
A hybrid cloud connects public and private clouds to share data and applications, fulfilling all specified requirements.
