Zorluk: OrtaRelational Data Storage Solutions

A legal services firm is deploying a new application on Azure that uses a relational database. The design must accommodate the following requirements:

- The database must support cross-database queries and SQL Server Agent.
- The database must be highly available and resilient to zone outages.
- Administrative effort for managing the underlying operating system must be eliminated.

Which relational database solution and configuration should you recommend?

  1. A
    Azure SQL Database single database configured with zone-redundant storage
  2. B
    SQL Server on Azure Virtual Machines configured with zone-redundant storage
  3. Azure SQL Database Managed Instance configured with zone-redundant storageCevap
  4. D
    Azure SQL Database Managed Instance configured with locally redundant storage

Cevap

Azure SQL Database Managed Instance configured with zone-redundant storage
The correct option is Azure SQL Database Managed Instance configured with zone-redundant storage because it supports instance-level features such as SQL Server Agent and cross-database queries, requires no operating system management, and is resilient to availability zone failures through zone-redundant replication.

Adım Adım Çözüm

1
Evaluate feature requirements.
SQL Server Agent and cross-database queries require instance-level features, ruling out Azure SQL Database single database.
Azure SQL Database single database does not natively support SQL Server Agent or cross-database queries.
2
Evaluate management requirements.
Operating system administrative effort must be eliminated, ruling out SQL Server on Azure Virtual Machines.
SQL Server on Azure VMs is a fully self-managed Infrastructure-as-a-Service (IaaS) option requiring OS patching.
3
Evaluate resiliency requirements.
Resilience to zone outages requires a zone-redundant storage option.
Locally redundant storage is limited to a single facility and cannot survive a zone failure, whereas zone-redundant storage replicates data across multiple zones.
