5 AGENDA

6 Hybrid Solutions with SQL Server 2016 Cloud-based AlwaysOn Availability Group Replicas Stretch Databases Enhanced Backups to the Cloud Better consistency in working with SQL Server on-premises, SQL Server on Azure Virtual Machines, and Azure SQL DB means that these solutions can all appear as transparent to your applications.

7 HYBRID SOLUTIONS ALWAYS ON AVAILABILITY GROUPS

Highly redundant storage on SAN Clustering vmotion / Live

8 Cloud-Based AlwaysOn Availability Group Replica Common On-Premise HA/DR Scenarios: Less Redundancy More Redundancy Highly redundant storage on SAN Clustering vmotion / Live Migration to move VM to another host AlwaysOn Availability Groups

Cloud-Based AlwaysOn Availability Group Replica Azure SQL Server 2012 2016 and later Primary Replica Secondary Replica Secondary Replica Multi-Site Extend to Azure Cluster Multiple Secondaries:

9 Cloud-Based AlwaysOn Availability Group Replica Azure SQL Server and later Primary Replica Secondary Replica Secondary Replica Multi-Site Extend to Azure Cluster Multiple Secondaries: but up to only 3 synchronous 1 Listener Load-balanced routes asynchronous the connections secondaries Basic (2 nodes) for Std Edition Listener routes the connections Primary Site Remote Site Listener

10 Cloud-Based Always On Availability Group Replica As easy as 1. Ensure your primary is running on a cluster 2. Run the wizard 3. Enjoy your secondary in Azure

11 Full HA/DR in Azure Simplified Distributed AG Primary Secondary Forwarder Secondary On Premise Azure

12 HYBRID SOLUTIONS STRETCH DATABASE

13 Issues with large DB or tables Tables are becoming massive because: Users want to keep their data forever Cold data in the tables accessed infrequently but must be online Maintenance challenges backups / DBCC

14 Stretch Databases Allows the movement of entire tables or identified rows and/or columns to be moved to Azure SQL DB CTP3 limited to moving entire tables Post-CTP3 release will allow selection of rows/columns based on a predicate Limitations (as at CTP 3) Unique / Primary Key constraints not enforced UPDATE / DELETE operations not permitted ALTER TABLE not permitted (other than to set MIGRATION_STATE) Indexed Views cannot reference a stretch table

15 Stretch Databases Eligibility Restrictions: Data types: timestamp sql_variant XML geometry / geography hierarchyid UDTs Column types: computed columns COLUMN_SET Constraints: FK constraints that reference the table DEFAULT constraints CHECK constraints Indexes: XML indexes Full Text indexes Spatial indexes Table properties: Max 1023 columns Less than 998 indexes FILESTREAM data File Tables Replication CDC or Change Tracking Memory-Optimised

18 HYBRID SOLUTIONS BACKUPS IN AZURE

19 Enhanced Backups to Azure Azure backup options: SQL Server 2012 Backup to Azure blob storage Backup to Windows Azure Tool SQL Server 2014 URL selectable in SSMS dialog box Managed Backup to Windows Azure SQL Server 2016 Block blobs can be used to stripe backups Snapshots for data files on Azure blob storage Enhanced Managed Backup to Windows Azure

20 Enhanced Backups to Azure Backup to block blobs Previous versions could only specify a single page blob (max size 1 TB) Block size is variable up to 4 MB and each block blob can contain up to 50,000 blocks (max block blob size = 195 GB) Can stripe the backup over multiple files improving throughput and size of the backup (effectively unlimited) Requires a Shared Access Signature for the Azure Storage Account (used to create a SQL Credential)

21 Enhanced Backups to Azure File-Snapshot Backups Requires the database files to be hosted on Azure Storage The.bak file doesn t contain the data pointers to the corresponding snapshots Backup must be to same storage account as the database files use
