What is Azure SQL Database?
A relational database-as-a-service, fully managed by Microsoft.
Delivers predictable performance, elastic scale, business continuity and programmatic functionality.
For cloud-designed apps when near-zero administration and enterprise-grade capabilities are key.
Perfect for cloud architects and developers looking for programmatic DBA-like functionality.

Current approach
Valued on database size
Polar service models; light-weight or high-end
Missing intermediate steps
Customers value
Efficiency, performance & business continuity
Progressive service model aligned with
application patterns, billing simplicity
New service model principles
Provide strong availability SLA and
performance and disaster recovery SLOs
Predictable model; features and functionality
as a continuum
Introducing new service tiers – in preview
Elastic scale & performance: Six performance levels across three tiers for scale up and
down based on throughput needs. Better resource isolation Improved billing
experience.
Business continuity: A spectrum of business continuity features from light-weight to
mission-critical across the tiers. Customers can dial up the control over data recovery
and failover.
Familiar & Self-managed: Unprecedented efficiencies as your applications scale with a
near-zero maintenance service and a variety of familiar management tools &
programmatic APIs.
Azure SQL Database New Service Tiers
*SLAs will take effect at time of GA, Azure previews are subject to different service terms, as set forth in preview supplemental terms.
**Not all restore & disaster recovery features are available today, visit the disaster recovery documentation page to learn more.
***Auditing and Data masking will be added to public preview shortly
Predictable performance levels
Redefined
Across the service tiers, each performance level is assigned a
defined level of throughput for a streamlined experience
Measure of
power
Introducing the Database Throughput Unit (DTU) which
represents database power and replaces hardware specs
% CPU
% read
% write
% memory
DTU is defined by the bounding box for
the resources required by a database
workload and measures power across
the six performance levels.
Basic — 5 DTU S0 — 10 DTU* P1 — 100 DTU
S1 — 20 DTU P2 — 200 DTU
S2 — 50 DTU P3 — 800 DTU
Dashboard views of metrics
Monitor
Quickly understand DB resource usage via percent of resources
consumed for each resource type over time and database size
Available in the management
portal & via APIs
In contrast to a VM, no systemrelated overhead—focused on
just the resources used to run
your database workload
In-depth views (DMVs) are also
available for deeper
understanding and troubleshooting (for example, at the
query level)
Point-in-time restore
Programmatic “oops recovery” of data deletion or alteration
Auto backups, transactional logs every 5 min
Backups in Azure Storage and geo-replicated
Creates a side-by-side copy, non-disruptive
REST API, PowerShell or Azure Portal

Data masking
Prevent the abuse of sensitive data by hiding it from users
Configuration made easy in the new Azure portal
Policy-driven at the table and column level, for a
defined set of users
Data masking applied in real-time to query results
based on policy
Multiple masking functions available (e.g. full, partial)
for various sensitive data categories (e.g. Credit Card
Numbers, SSN, etc.)
