Based on customer feedback, Azure SQL Database is introducing new service tiers to help customers more easily innovate with cloud-designed database workloads. At the heart of this change, the new tiers deliver predictable performance across a spectrum of six performance levels for light- to heavy-weight transactional application demands.  Additionally, the new tiers offer a spectrum of business continuity features, a stronger uptime SLA, larger database sizes for less money, and an improved billing experience.
*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

9. 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*
S1 — 20 DTU
S2 — 50 DTU
P1 — 100 DTU
P2 — 200 DTU
P3 — 800 DTU

10. 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 system- related overhead—focused on just the resources used to run your database workload
In-depth views (DMVs) are also available for deeper understanding and trouble- shooting (for example, at the query level)

11. 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
Backups retention policy:
Basic, up to 7 days
Standard, up to 14 days
Premium, up to 35 days

Scale out layer
Status: Private preview
fall public preview

18. Unlock savings in the new tiers
Larger DBs for less money
Backups workaround via import/export
Disaster Recovery via DataSync
Scenario: Today, customer pays $45 and $225 for 10GB and 150GB databases, respectively.
Solution: With Standard, customer gets access to 250GB databases at a flat rate of $40 and $200 and greater performance assurance and business continuity.
Scenario: Customer uses DB Copy & export to create database copies as backups which incurs additional database cost.
Solution: Restore removes the need for the customer to carry the extra DB cost which can cut their database count by up to 50%, leaving headroom to dial- up performance.
Scenario: Customer uses Azure DataSync (in preview) to create geo-replicated databases which incurs additional database cost and doesn’t assure transactional consistency after failover.
Solution: Geo-Replication in Standard is built-in and discounts the passive, secondary database by 25% which can save money on the total bill and assures transactional consistency.
