- Single database
- Elastic pools
- Managed instance
Key Features:
- Intelligent performance insights
- Built-in security with Advanced Threat Protection
- Automatic backups and point-in-time restore
- Hyperscale and Serverless options for flexible scaling
Azure Database for PostgreSQL
Offers a fully managed database service for application developers and businesses who need a reliable and high-performing relational database. It's based on the community edition of the PostgreSQL relational database.
Key Features:
- High availability with automatic failover
- Data encryption at rest and in transit
- Integration with Azure services like Azure Monitor and Azure Active Directory
- Flexible compute and storage options
Azure Database for MySQL
A managed relational database service that is based on the MySQL Community Edition database engine. It's suitable for MySQL application workloads.
Key Features:
- High availability with automatic failover
- Data encryption at rest and in transit
- Integration with Azure services
- Flexible pricing tiers including burstable options
NoSQL Databases
For applications requiring flexible schemas, high scalability, and global distribution, Azure's NoSQL offerings provide the ideal solution.
Azure Cosmos DB
Microsoft's globally distributed, multi-model database service. Cosmos DB allows you to elastically and globally scale throughput and storage with transparent, multi-region data distribution, low latency, and guaranteed high availability.
Key Features:
- Guaranteed low latency at the 99th percentile
- Multi-API support (SQL, MongoDB, Cassandra, Gremlin, Table)
- Global distribution with active-active replication
- Tunable consistency levels
- Automatic scaling of throughput and storage
In-Memory Caching
Accelerate application performance by reducing the latency of data access with Azure's managed in-memory caching service.
Azure Cache for Redis
A fully managed, open-source compatible Redis cache that enables high-performance data access. It's ideal for scenarios requiring fast data retrieval.
Key Features:
- High throughput and low latency
- Support for Redis persistence and replication
- Premium tier offers clustering, VNet integration, and geo-replication
- Managed service with automatic patching and monitoring
Choosing the Right Database
Selecting the appropriate Azure database service depends on your application's specific requirements, including:
- Data structure (relational, document, key-value, graph, etc.)
- Scalability needs (throughput, storage)
- Consistency requirements
- Geographic distribution needs
- Performance expectations (latency, throughput)
- Development language and existing technology stack
Azure's extensive portfolio ensures you can find a managed database solution that perfectly fits your workload.
