The document introduces Azure SQL as a managed service version of SQL Server available through various pricing models, emphasizing its affordability and performance advantages over earlier systems. It outlines different models such as DTU and VCore for pricing and performance metrics, alongside details on migration strategies and security features. Additionally, the document highlights the service's backup capabilities and options for existing applications versus new cloud applications.
Intro to Azure SQL database
- 1. INTRODUCING TO AZURE SQL #SQLsat712
- 2. HELLO MY NAME IS STEVE Managing Director of StratosTechnology Partners SharePoint Consultant Microsoft MVP for Office Servers and Services Based in Christchurch, New Zealand Twitter: @nztechtweet Email: [email protected]
- 3. MY SQL JOURNEY • Digital EquipmentCorporationVAX • VMS Operating System • Rdb relational database • Terrible performance • Extremely expensive • Green screen (or XTerm) Oracle said “even if Rdb were free, you couldn’t afford it”. They were probably right.
- 4. CANWE DOTHIS BETTER? • 1 CPU – Pentium 90 with 2 x 52MB IDE (IMP52) drives mirrored • Performance was almost 10 times theVAX on the same task • Price was nearly 25 times less! • I found a bug and Microsoft released a hot fix • The solution was affordable for other orgs with smaller budgets • The same core software is still in use today, more than 25 years later running on SQL 2016 FUN FACT: DECVMS included LAN Manager, the forerunner of Windows NT’s networking
- 5. SLIDE FOR MARTIN CATHERALL Steve, can you tell me more about SharePoint?
- 7. WHAT IS AZURE SQL? Managed Service version of SQLserver (PaaS model) Available in two pricing models Throughput based model (DTU – DatabaseThroughput Units) CPU based model (preview) Infrastructure as a Service (IaaS) SQL Server running on anAzureVirtual Machine Essential the same functionality as on-premises but hosted in Azure data centres Docker -> https://azure.microsoft.com/en-us/resources/videos/connect-2017-use-sql- server-2017-in-docker-containers-for-your-ci-cd-process/

DATABASETHROUGHPUT UNIT MODEL (DTU) Basic Standard Premium Target workload Development and production Development and production Development and production Uptime SLA 99.99% 99.99% 99.99% Backup retention 7 days 35 days 35 days CPU Low Low, Medium, High Medium, High IO throughput (approximate) 2.5 IOPS per DTU 2.5 IOPS per DTU 48 IOPS per DTU IO latency (approximate) 5 ms (read), 10 ms (write) 5 ms (read), 10 ms (write) 2 ms (read/write) Columnstore indexing N/A S3 and above Supported In-memory OLTP N/A N/A Supported http://dtucalculator.azurewebsites.net/
- 11. DTU STORAGE Basic Standard Premium Maximum storage size* 2 GB 1TB 4TB Maximum DTUs 5 3000 4000 Basic Standard Premium Maximum storage size per database* 2 GB 1TB 1TB Maximum storage size per pool* 156 GB 4TB 4TB Maximum eDTUs per database 5 3000 4000 Maximum eDTUs per pool 1600 3000 4000 Maximum number of databases per pool 500 500 100 Single Database Elastic Storage Pools
- 12. VCORE MODEL (PREVIEW) In the vCore-based purchasing model (preview) customers pay for: Compute (service tier + number of vCores + generation of hardware)* Type and amount of data and log storage Number of IOs** Backup storage (RA-GRS)** * In the initial public preview, the Gen 4 Logical CPUs are based on Intel E5-2673 v3 (Haswell) 2.4-GHz processors ** During preview, 7 days of backups and IOs are free
- 13. VCORE PERFORMANCE General Purpose Business Critical Best for Most business workloads. Offers budget oriented balanced and scalable compute and storage options. Business applications with high IO requirements. Offers highest resilience to failures using several isolated replicas. Compute 1 to 80 vCore, Generation 4 andGeneration 5 1 to 80 vCore, Generation 4 andGeneration 5 Memory 7 GB per core 7 GB per core Storage Premium remote storage, 5 GB – 4TB Local SSD storage, 5 GB – 4TB IO throughput (approximate) 500 IOPS per vCore with 7000 maximum IOPS 5000 IOPS per core with 200000 maximum IOPS Availability 1 replica, no read-scale 3 replicas, 1 read-scale, zone redundant HA Backups RA-GRS, 7-35 days (7 days by default) RA-GRS, 7-35 days (7 days by default)* In-Memory N/A Supported
- 14. PAAS OR IAAS? Azure SQL New cloud apps Need rapid deployment Need built in HA and DR Don’t want to manage a server Databases size up to 4TB SQL Server on AzureVirtual Machine Existing Applications Minimal change to applications You want to manage, patch and configure Need full administrative rights Database size up to 64TB
- 15. SECURITY Data Protection Encryption Data Discovery and Classification Access Control Firewall Authentication (SQL andAAD) Authorisation (roles) Row-level security Dynamic Data Masking Proactive Monitoring Auditing Threat Protection Compliance SQL compliance certifications Security Management VulnerabilityAssessment
- 19. TRANSACTIONAL REPLICATION If you want to minimise downtime use transactional replication from your existing on premises SQL server to Azure SQL Publish your source database Subscription on the destination database Everything in the schema appears in the Azure SQL database You can replicate a subset of objects or everything Once all data has replicated, stop replication and switch your application to the new datasource
- 20. MIGRATINGTO A MANAGED INSTANCE • Restore of system databases is not supported.To migrate instance level objects (stored in master or msdb databases), we recommend to script them out and runT-SQL scripts on the destination instance. • You can also use BACPAC to copy your source database and import into Azure SQL databases
- 21. BACKUP Point in time backups every 5-10 mins Backup retention: Basic service tier – 1 week Standard service tier – 5 weeks Advanced service tier – 5 weeks Long term retention Up to 10 years Weekly full backups copied to long term storage Backups are encrypted ifTDE is enabled on the database
- 22. RESTORE
- 23. HOW MUCH DOES IT COST? https://azure.microsoft.com/en-us/pricing/details/sql-database/managed/
- 24. BURNING QUESTIONS? Don’t ask me, I’m an MVP for SharePoint ;) See people like Simon,Warwick, Shaun and Hamish.These guys live and breath this stuff!
