SQL Server and Azure: Hybrid Scenarios and Features
Luis VargasSenior Program Manager
BRK2554
SQL Server integrates cloud services from Azureproviding end-to-end experiencesthat are optimized and use familiar interfaces
Key Takeaway
• Environment that combines resources from on-premise and cloud• Physical Machines• VMs• Storage• Domain Controllers• Databases
• SQL Server on-premise using cloud resources• SQL Server on cloud using on-premise resources
Hybrid Cloud
SQL Server & Hybrid Cloud
On-Premises
SQL Server on-premise using cloud resources
Cloud resources
Azure Storage• Unlimited storage• No data loss
• 3 local sync copies• Optionally: 3 remote async copies readable
• Highly available (automated disk healing)• Low cost: $0.02 p/GB/month
Azure VMs• VMs hosted in Azure• Created from Microsoft Gallery Images or your own Images
• SQL Server 2008R2/2012/2014 Web/Standard/Enterprise• Elastic: 1 core, 2 GB RAM, 1 TB data 32 cores, 512 GB RAM, 32 TB data• Highly available (automated VM healing)• Cost: $0.70 p/h for SQL Standard on 4-core, 8GB RAM VM
Accessing cloud resourcesOver the Internet
• Public endpoints• Free
Over a site-to-site VPN tunnel• VPN Device or Windows Server RRAS• Encrypted (IKE, AES)• ~10MB p/sec (600MB p/min, 35GB p/hour)• $0.19 p/hour
DemoStorage Accounts, VMs, and VPN tunnels
• Microsoft builds both SQL Server and Microsoft Azure Thus it can provide end-to-end experiences that are optimized and use familiar interfaces

Azure VM
On-premise
• Unlimited low-cost storage• Off-site (compliance)• No device management• Media safety (geo-redundant)• Encrypted and compressed• Accessibility
• SSMS, T-SQL, PowerShell• Azure Portal, CloudExplorer
• Encryption• Certificates (AES256, AES128)
• Compression
Backup
Restore
Restore
• Databases can be backed up to Azure Storage• Full/Differential/Log (Max 1TB uncompressed)• Regular/Copy-Only
• Backups can be restored from on-premise or an Azure VM
Benefits
100 GB DB (compressed):Backup: 20 min, Restore: 1h
Recovery• Data
• Media failure or undesired action (e.g. DROP TABLE)• Restore to any on-premise SQL Server
• Cheap Disaster Recovery• Restore to an Azure VM and redirect applications
Dev/Test• Restore to an Azure VM and give access to developers
Backup to Windows Azure Storage - Scenarios
DemoBackup/Restore to/from Azure Storage
Support block blobs (besides page blobs)• 3x cheaper ($0.03 vs $0.09 p/GB)
Stripping• Divide a backup into multiple blobs• Allows backups larger than 1TB• Faster backup/restore (parallel I/O)
Backup to Windows Azure Storage - SQL Server 2016
BACKUP DATABASE <database> TO URL = 'https://<account>.blob.core.windows.net/<container>/<blob1>', URL = 'https://<account>.blob.core.windows.net/<container>/<blob2>‘…
Backup to Windows Azure Storage Tool
• Downloadable tool that allows backup to Azure Storage from previous versions of SQL Server
• Copies backups from local directories to Azure Storage
Benefits• Single backup strategy to cloud across SQL Server 2005, 2008, 2008 R2, 2012, and
2014• Provides backup encryption• Easy configuration
DemoBackup to Windows Azure Storage Tool
Managed Backup• Feature that automates SQL Server backups to Azure Storage based on workload• It also automates the backup retention (configurable)
Benefits• No need to define & manage backup policy
• Full Backup when log growth >1GB• Log backup when log growh > 5MB
• Ensures a consistent backup chain• Full backup taken if chain is broken
• Covers some/all DBs• Retries on errors (e.g. network)
• Unlimited low-cost storage• Off-site (compliance)• No device management• Media safety (geo-redundant)• Encrypted and compressed• Accessibility
• SSMS, T-SQL, PowerShell• Azure Portal, CloudExplorer
Plus same as before:
DemoEnable and trigger Managed Backup
Scheduling• Allow specifying when to take full backups and how often to take log backups
Staging• Keep a local copy of the last part of the backup chain

Data Files in Azure Storage
DB3COLD
On-Premise
DB1HOT
• Store historical/cold DBs/filegroups in Azure Storage• Secure access via Transparent DB Encryption• Read workloads optimized via Buffer Pool• DBs can be attached by another server or Azure VM (basic migration/recovery)
• Unlimited low-cost storage• Media safety (geo-redundant)• Accessibility/Programmability
• T-SQL, PowerShell• Azure Portal, CloudExplorer
• Encrypted and compressed
DB2HOT

DemoStore data files in Azure Storage
AlwaysOn Replicas in Azure VMs• Extend AlwaysOn Availability Groups with replicas in Azure VMs
Benefits• Low TCO
• Just VM and Storage, free ingress traffic• No DR site cost (rent, hardware, ops)
• Any Azure region (America, Europe, Asia)• Azure Storage guarantees no data loss• Azure VM is highly available
Disaster Recovery• Manually failover to (warm) secondary replica
Offload work off the primary• Read workloads (Reporting, BI)• Backups (compliance)
Backup to Windows Azure Storage - Scenarios
Before extending AlwaysOn configurationConfigure site-to-site VPN tunnel between on-premise and Azure

AlwaysOn Replica in Azure - Sample Deployment
Windows Cluster
DemoAdding an AlwaysOn Replica in an Azure VM
Dealing with lots of data in Hybrid Cloud•Azure Import service
• Ship backups to Azure Storage via physical drives (max 4TB each)• Encrypted with BitLocker
• Recommended for backups larger than 1 TB
•Windows Azure Express Route service• Dedicated network link to an Azure data center
• Many providers (A&T, Equinix, Verizon, BT, Level3, ..)• Guaranteed high bandwidth (up to 10Gbps)• Recommended for workloads generating more than 20 MBPs
SQL Server on cloud using on-premise resources
SQL Server on cloud using on-premise resources•Provisioning an Azure VM with SQL Server
• Microsoft Gallery• SQL 2014 (Enterprise , Standard, Web, OLTP Optimized, DW Optimized)• SQL 2012 (Enterprise , Standard, Web, OLTP Optimized, DW Optimized)• SQL 2008 R2 (Enterprise, Standard, Web)
• Your own Images
•Migrating on-prem DBs to Azure• SQL Server Deployment Wizard
•Accesing on-premise resources (requires site-to-site VPN tunnel)
• Active Directory• Join VM to on-premise Windows Domain to use Windows logins and
policies • Other SQL Server(s)
• Configure Linked Servers
