Service Tiers

Basic

• Best suited for a small size database, supporting typically one single active operation at a given time.

Standard

• The go-to option for most cloud applications, supporting multiple concurrent queries.

Premium

• Designed for high transactional volume, supporting a large number of concurrent users and requiring the highest level of business continuity capabilities.

Overview of the Performance Model

Basic

• DTU = 5

• Max DB Size = 2GB

• 16 600 Trans/hour

Standard

• S0/S1/S2/S3

• DTU = 10 – 100

• Max DB Size = 250 GB

• 5100 Trans/min

Premium

• P1/P2/P3

• DTU = 125 – 1000

• Max DB Size = 500 GB

• 735 Trans/sec

Upgrade to a Higher Service Tier

Downgrade to a Lower Service Tier

Changing Performance Level

Scale up or down

Impact of Database Changes• Connections to the database may be

temporarily dropped

• SLO change for a database often involves data movement

3 x (5 minutes + database size / 150 MB/minute)

Scale up or down

Dynamic Data MaskingDemo

Row-level Security• Control access to rows in a database table

based on the characteristics of the user executing a query

• Simplifies the design and coding of security in your application.

• The access restriction logic is located in the database tier not in the application tier

Auditing• Tracks database events and writes

audited events to an audit log

• Auditing can help you with• Maintain regulatory compliance• Understand database activity• Gain insight into discrepancies and anomalies

Retain an audit trail of selected events.

Automatic Backup

Creates backups of every active database

Every hour a backup is taken

Geo-replicated

Every 5 minutes a transaction Log backup is taken

Point-in-Time RestoreDesigned to recover a database to a specific point in time

Creates a new database with the same service tier

The time taken to complete a restore depends on the size of the database and the length of the log chain
