 VM hosted on Microsoft Azure Infrastructure (“IaaS”)
• From Microsoft images (gallery) or your own images (custom)
SQL 2008R2 / 2012 / 2014 / 2016 Web / Standard / Enterprise
Images refreshed with latest version, SP, CU
• Fast provisioning (~10 minutes).
• Accessible via RDP and Powershell
•
 Pay per use
• Per minute (only when running)
• Cost depends on size and licensing
• EA customers can use existing SQL licenses (BYOL)
• Network: only outgoing (not incoming)
• Storage: only used (not allocated)
 Elasticity
• 1 core / 2 GB mem / 1 TB   32 cores / 448 GB mem / 64 TB

Migrating Data
Migrate from on-prem SQL server to Azure VM IaaS:
• Use the Deploy a SQL Server Database to a Microsoft Azure VM wizard. Recommended method for migrating an on-premises user database
when the compressed database backup file is less than 1 TB. Use on SQL Server 2005 or greater to SQL Server 2014 or greater
• Perform on-premises backup using compression and manually copy the backup file into the Azure virtual machine and then do a restore (only if
you cannot use the above wizard or the database backup size is larger than 1 TB). Use on SQL Server 2005 or greater to SQL Server 2005 or
greater
• Perform a backup to URL and restore into the Azure virtual machine from the URL. Use on SQL Server 2012 SP1 CU2 or greater to SQL Server
2012 SP1 CU2 or greater
• Detach and then copy the data and log files to Azure blob storage and then attach to SQL Server in Azure VM from URL. Use on SQL Server
2005 or greater to SQL Server 2014 or greater
• Convert on-premises physical machine to Hyper-V VHD, upload to Azure Blob storage, and then deploy as new VM using uploaded VHD. Use
when bringing your own SQL Server license, when migrating a database that you will run on an older version of SQL Server, or when migrating
system and user databases together as part of the migration of database dependent on other user databases and/or system databases. Use on
SQL Server 2005 or greater to SQL Server 2005 or greater
• Ship hard drive using Windows Import/Export Service. Use when manual copy method is too slow, such as with very large databases. Use on SQL
Server 2005 or greater to SQL Server 2005 or greater
• If you have an AlwaysOn deployment on-premises and want to minimize downtime, use the Add Azure Replica Wizard to create a replica in Azure
and then failover, pointing users to the Azure database instance. Use on SQL Server 2012 or greater to SQL Server 2012 or greater
• If you do not have an AlwaysOn deployment on-premises and want to minimize downtime, use SQL Server transactional replication to configure
the Azure SQL Server instance as a subscriber and then disable replication, pointing users to the Azure database instance. Use on SQL Server
2005 or greater to SQL Server 2005 or greater
• Others: data-tier application, transact-SQL scripts, sql server import and export wizard, SSIS, copy database wizard

Automated Patching
• Predictable solution for patching (Windows & SQL)
• Simple: just specify a time window
• Uses SQL Agent Extension and MS Update
• Portal and Powershell
• It relies on the Windows Update and the Microsoft
Update infrastructure and installs any update that
matches the ‘Important’ category for the machine

20.
Automated Backup
• For all DBs in the SQL instance
• Simple: just specify a retention period
• Supports Compression and Encryption
• Portal and Powershell
• Full database and transaction log backups
• Configure at database level or SQL Server instance level
In SQL Server 2016:
• Full, bulk-logged and simple recovery models are all
supported
• System databases can be configured for backups
• Backup striping can be used to support backup sizes of up to
12 TB
• Customer backup schedules can be specified to ensure your
backups are created when it is best for your workload

Attach SSD/HDD up to 1TB. These
are .vhd files

25.
Azure Default Blob Storage
 Azure Storage Page Blobs, 3 copies
 Storage high durability built-in (like have RAID)
 VHD disks, up to 1 TB per disk (64 TB total)

26.
Geo-storage replication
 3 copies locally, another 3 copies in different region
 Disable for SQL Server VM disk (consistent write
order across multiple disks is not guaranteed).
Instead use DR techniques in this deck

HA/DR pieces

HA/DR deployment architectures
Azure Only
Availability replicas

multiple datacenters
in Azure VMs for
disaster recovery.
Cross-region solution
protects against
complete site outage.
Hybrid
Some availability
replicas running in
Azure VMs and other
replicas running on-
premises for cross-
site disaster recovery.
HA only, not DR

WSFC running in
Azure VMs with
storage supported by
a third-party
clustering solution.

Principal, Mirror, and
Witness run within
same Azure data
center, deployed
using a DC or server
certificates for HA.
Hybrid

Log shipping
depends on Windows
file sharing, so a VPN
connection between

required.

RPO/RTO
RTO – Recover Time Objective. How much time after a failure until we have to be up
and running again?
RPO – Recover Point Objective. How much data can we lose?
• HA – High Availability
• RTO: seconds to minutes
• RPO: Zero to seconds
• Automatic failover
• Well tested (maybe with each patch or release)
• DR – Disaster Recovery
• RTO: minutes to hours
• RPO: seconds to minutes
• Manual failover into prepared environment
• Tested from time to time
How long does it take to fail over:
• Backup-Restore: Hours
• Log Shipping: Minutes
• AlwaysOn FCI: Seconds to minutes
• AlwaysOn AG/Mirroring: Seconds

31.
AlwaysOn Availability Groups
Azure Only
Availability replicas
running across
multiple datacenters
in Azure VMs for
disaster recovery.
Cross-region solution
protects against
complete site outage.
Hybrid
Some availability
replicas running in
Azure VMs and other
replicas running on-
premises for cross-
site disaster recovery.
Availability replicas running across multiple datacenters in Azure
VMs for disaster recovery. This cross-region solution protects
against complete site outage.
Within a region, all replicas should be within the same cloud
service and the same VNet. Because each region will have a
separate VNet, these solutions require VNet to VNet connectivity.
For more information, see Configure a Site-to-Site VPN in the
Azure classic portal.
All availability replicas running in Azure VMs for high
availability within the same region. You need to configure a
domain controller VM, because Windows Server Failover
Clustering (WSFC) requires an Active Directory domain.
For more information, see Configure AlwaysOn Availability
Groups in Azure (GUI).

32.
AlwaysOn between Azure Regions
• Configure AlwaysOn between VMs in different geographic regions (asynchronous)
• Over secure tunnel
• Manual Failover (~15 seconds) in case of a regional failure
• Test it at any time
• Use closest secondary for read workloads
• Region 1: AG used instead
of FCI (synchronous)

33.
AlwaysOn Failover Cluster Instances (FCI)
An FCI on a two-node WSFC running in Azure VMs with remote
iSCSI Target shared block storage via ExpressRoute. For example,
NetApp Private Storage (NPS) exposes an iSCSI target via
ExpressRoute with Equinix to Azure VMs.
For third-party shared storage and data replication solutions, you
should contact the vendor for any issues related to accessing data
on failover.
Note that using FCI on top of Azure File storage is not supported
yet, because this solution does not utilize Premium Storage. We
are working to support this soon.
HA only, not DR
FCI on a two-node
WSFC running in
Azure VMs with
storage supported by
a third-party
clustering solution.

35.
Database Mirroring
Azure Only
Principal and mirror
and servers running
in different
datacenters for
disaster recovery.
Principal, Mirror, and
Witness run within
same Azure data
center, deployed
using a DC or server
certificates for HA.
Hybrid
One partner running
in an Azure VM and
the other running
on-premises for
cross-site disaster
recovery using server
certificates.
Principal and mirror and servers running in
different datacenters for disaster recovery. You
must deploy using server certificates because an
Active Directory domain cannot span multiple
datacenters.
Principal, mirror, and witness servers all running in the
same Azure datacenter for high availability. You can
deploy using a domain controller.
You can also deploy the same database mirroring configuration
without a domain controller by using server certificates instead.
