Azure SQL Database

使用雲端中受控的智慧型 SQL,建置可隨著您業務步調調整規模的應用程式

在完全受控的 SQL 資料庫上更快建置下一個應用程式

Part of the Azure SQL family, Azure SQL Database is an intelligent, scalable, relational database service built for the cloud. Optimize performance and durability with automated, AI-powered features that are always up to date. With serverless compute and Hyperscale storage options that automatically scale resources on demand, you’re free to focus on building new applications without worrying about storage size or resource management.

完全受控的 SQL 資料庫會自動更新、佈建並備份,以便您專注於應用程式開發

Flexible and responsive serverless compute and Hyperscale storage rapidly adapt to your changing requirements

Layers of protection, built-in controls, and intelligent threat detection keep your data secure

Built-in AI and built-in high availability maintain peak performance and durability with an SLA of up to 99.995 percent

完全受控且永遠使用最新版 SQL

Eliminate the complexity of configuring and managing high availability, tuning, backups, and other database tasks with a fully managed SQL database.

Accelerate your application development in the only cloud with evergreen SQL using the latest SQL Server capabilities, and never worry about updates, upgrades, or end of support again.



Break through the resource limitations that can affect your application’s performance. Azure SQL Database Hyperscale adapts to changing requirements by rapidly scaling storage up to 100 TB. Flexible, cloud-native architecture allows storage to grow as needed and enables you to back up data almost instantaneously and restore your database in minutes—regardless of the size of the data operation.



Build modern apps your way with provisioned and serverless compute options. Azure SQL Database serverless simplifies performance management and helps developers focus on building apps faster and more efficiently with compute resources that automatically scale based on workload demand.

SQL Database serverless is best for scenarios where usage is intermittent and unpredictable and you only pay for compute resources you use on a per-second basis, which optimizes overall price performance.




Switch to Azure SQL Database and get better price performance than with other cloud providers. Azure SQL Database meets your mission-critical requirements and costs up to 86 percent less than the competition.1

Azure SQL Database 更新、部落格及公告

  • Azure SQL Database provides the following deployment options for an Azure SQL database:

    • As a single database with its own set of resources managed via a logical server.
    • As a pooled database in an elastic pool with a shared set of resources managed through a logical server

    In general, elastic pools are designed for a typical software-as-a-service (SaaS) application pattern, where there is one database per customer or tenant. Purchasing individual databases and over provisioning to meet the variable and peak demand for each database is often not cost efficient, but with pools, you manage the collective performance and the databases scale up and down automatically. Our intelligent engine recommends a pool for databases when a usage pattern warrants it. For details, see elastic pool guidance.

  • The Azure Hybrid Benefit for SQL Server helps you maximize the value from your current licensing investments and accelerate your migration to the cloud. Azure Hybrid Benefit for SQL Server is an Azure-based benefit that enables you to use your SQL Server licenses with active Software Assurance to pay a reduced rate (“base rate”) on vCore-based Azure SQL Database and Azure SQL Managed Instance. You may apply this benefit even if the SKU is active but note the base rate will be applied from the time you select it in the portal. No credit will be issued retroactively.

    You can activate the Azure Hybrid Benefit via the Azure Portal by attesting you have sufficient active licenses with Software Assurance.

    The Azure Hybrid Benefit for SQL Server provides:

    • The ability to move your licenses to a fully managed platform-as-a-service (PaaS) product. Azure is the only cloud that provides this ability. Amazon Web Services Relational Database Service (RDS) is not eligible for bring-your-own-license (BYOL) and must be offered as "license-included."
    • Four cores in the cloud for every one core on-premises for Enterprise edition customers in the general purpose or Hyperscale service tiers.
    • 180 days of dual-use rights to apply to current deployment (on premises or on third-party cloud) and in Azure to allow for data migration.
  • No. Azure SQL Database is a fully managed database service, which means that Microsoft operates SQL Server for you and ensures its availability and performance. SQL Database also includes innovative features to enhance your business continuity, such as built-in high availability. A comprehensive security portfolio allows you to implement intelligent features like threat detection, so that don’t have to worry about administering or maintaining hundreds or thousands of your SQL Server databases. View the full feature comparison of Azure SQL Database and SQL Server.
  • 以虛擬核心為基礎的服務層級主要依可用性、儲存體類型和 IOPS 來區分:

    一般用途提供一組預算導向且平衡的計算和儲存體選項,其中不會優先考慮 I/O 效能或容錯移轉時間。

    超大規模資料庫適用於大部分商務工作負載,已針對線上交易處理 (OLTP) 和混合式交易分析工作負載 (HTAP) 進行最佳化,並具備高調整性儲存體大小、讀取縮放,以及快速資料庫還原功能。

    「商務關鍵性」最適合需要高交易率且低 IO 延遲的 OLTP 應用程式。它使用多個已同步更新的複本,來提供最高的失敗復原力及快速容錯移轉。

  • Connectivity between your Microsoft Azure SQL Database and the Azure Internet gateway is guaranteed at least 99.99 percent of the time, regardless of your service tier. 0.01 percent is reserved for patches, upgrades, and failovers. For more information, read the SLA. For information about the availability architecture of Azure SQL Database, see high availability and Azure SQL Database.
