Zorluk: ZorShared Responsibility Model

An organization is migrating its custom inventory management system from Azure Virtual Machines (IaaS) to Azure App Service and Azure SQL Database (PaaS). Under the Microsoft Shared Responsibility Model, which responsibility shifts from the customer to Microsoft as a result of this transition?

  1. A
    Configuring and maintaining network firewall rules and access restrictions for the database
  2. Applying security updates and patches to the guest operating system and database engineCevap
  3. C
    Updating and patching the custom application code deployed to the web app
  4. D
    Managing the physical security of the datacenter hosting the servers

Cevap

Applying security updates and patches to the guest operating system and database engine
Migrating from Infrastructure as a Service (IaaS) to Platform as a Service (PaaS) reduces the customer's administrative overhead. In an IaaS model (Virtual Machines), the customer is responsible for maintaining and patching the guest operating system and database engine. When migrating to PaaS (App Service and Azure SQL Database), Microsoft assumes full responsibility for patching the operating system and database software.

Adım Adım Çözüm

1
Analyze the starting model (IaaS - Virtual Machines)
In IaaS, the customer is fully responsible for managing the guest operating system, database software configurations, network security groups, application code, and data. Microsoft is only responsible for the physical host, physical network, and hypervisor.
Establishing the baseline of responsibilities before the migration.
2
Analyze the target model (PaaS - Azure App Service and Azure SQL Database)
In PaaS, Microsoft takes over the management of the operating system, database engine software, physical hardware, and virtualization layers. The customer retains responsibility for applications, data, identities, and network configurations (such as firewalls and access rules).
Identifying the target state of responsibilities under the Platform as a Service model.
3
Identify the delta (responsibility that shifts from customer to Microsoft)
The management, updating, and patching of the guest operating system and the database engine software shift from the customer (responsible in IaaS) to Microsoft (responsible in PaaS).
Matching the shift to find the correct answer.

Anahtar Kavram

Under the Azure Shared Responsibility Model, migrating from IaaS to PaaS shifts the responsibility of operating system maintenance, database engine patching, and middleware management from the customer to the cloud provider (Microsoft).
