Vitor Fava
MVP Data Platform
Pass Chapter Leader do SQLManiacs
SQL Server Database Consultant na Pythian
CEO da Vita Database Solutions
Welcome students to the course and introduce yourself. Provide a brief overview of your background to establish credibility.
Ask students to introduce themselves and provide their backgrounds, product experience, and expectations of the course.
Record student expectations on a whiteboard or flip chart that you can reference during class.

4. What is Cloud Computing?
What is the cloud? Where is the cloud? Are we in the cloud now?
Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive.
Software-as-a-Service (SaaS)
Infrastructure-as-a-service (IaaS)
Platform-as-a-Service (PaaS)

5. What is SQL Database?
Relational database service in the cloud based on the market-leading Microsoft SQL Server engine, with mission-critical capabilities.
Delivers predictable performance, scalability with no downtime, business continuity and data protection—all with near-zero administration
Focus on rapid app development and accelerating your time to market, rather than managing virtual machines and infrastructure.
Because it’s based on the SQL Server engine, SQL Database supports existing SQL Server tools, libraries and APIs, which makes it easier for you to move and extend to the cloud.

6. Azure – Service Tiers

7. What is DTU? DTU = Database Throughput Units
Resources assigned to a database
Unified measure of CPU+Memory+Read/write rates
CPU
40%
65%
30%
50%
Writes
Reads
Memory
Utilization

8. DTU Calculator How to calculate the needed DTU to my SQL Database?
You can predict the service tier 
Too much: Not cost effective.
Too less: You can put your database in trouble (and you!).
DTU Calculator
Online service (
Based on collected performance indicators.
Processor - % Processor Time
Logical Disk - Disk Reads/sec
Logical Disk - Disk Writes/sec
Database - Log Bytes Flushed/sec
Does not take into account:
Uptime SLA
Point in time Restore
Performance Objective

9. Managing a SQL Database
Azure Portal  
Web-based application where you can create, update, and delete databases and logical servers and monitor database activity
SSMS and Data Tools
Client tools that run on your computer and allow you to connect to, manage, and develop your database in the cloud.
Command line tools
You can use command line tools such as PowerShell to manage databases and elastic database pools, and to automate Azure resource deployments.

10. Backup/Restore
Point-in-time Restore - return the database to an earlier point in time. A kind of regular “restore”.
Automatic backups:
Weekly* full backup;
Daily* differential backup;
Log backups every 5 minutes;
*automatically uploaded to geo-redundant Azure Storage

11. Restore to any Azure region
Business Continuity
Geo-Restore - default recovery option when a database is unavailable. Restores last daily backup to another region, using a geo-replicated backup copy.

12. Business Continuity
Standard Geo-Replication - When the primary database fails you can initiate failover to a non-readable secondary. Offline secondary, fixed DR pairing.

You must reconfigure the new secondary databases.

13. Business Continuity
Active Geo-Replication - Up to 4 readable secondaries, with configurable regions. A kind of AG in the cloud.

14. MONITORING A SQL DATABASE
DMVs
Extended Events
Query Performance Insight

15. Query Performance Insight
Deeper insight into your databases resource (DTU) consumption;
The top CPU consuming queries, which can potentially be tuned for improved performance.
The ability to drill down into the details of a query, view its text and history of resource utilization.
Performance tuning annotations that show actions performed by SQL Azure Database Advisor
