2. Talk to me, you will find out why.
Who are you?
I am a SQL Server nerd. Very excited to see SQL Server 2017! I am here to learn what is new in the HADR space in this release!
I am a Linux guru. I had heard there is something called “SQL Server”. But hey, if you didn’t run on Linux, you didn’t have my attention. Heard SQL Server is coming to Linux. Now you have my interest!
None of the above.
I am unique.
Talk to me, you will find out why.
I have been playing with SQL Server on Linux for a while. I am here to learn HA and DR on Linux. Exciting stuff!
I already know everything about what you are going to talk. I am here for fun, and to contribute to the conversations. And to give my feedback. You got to listen to me!

5. SQL Server HA and DR solutions
Simple
Standard
Mission critical
VM failover
Resilience against guest and OS-level failures
Minutes RTO
Backup and restore DR
Minutes to hours RTO
Failover cluster
Instance-level protection
Seconds to minutes RTO
Basic availability groups
AG with 2 replicas
Log shipping
Warm standbys for DR
Always On availability groups
Database level protection
Seconds to minutes RTO
Distributed availability groups DR

6. Flexibility of HADR architectures with your choice of platform
SQL Server support for Linux, including high availability capabilities
Enhanced Microsoft Distributed Transaction Coordinator (DTC) support for Always On Availability Groups
Read scale-out without depending on cluster infrastructure
Cross platform scenarios
Required synchronized secondaries to commit
SQL Server 2017
Flexibility of HADR architectures with your choice of platform

7. HADR on Linux for mission critical applications
Scenario
All Linux infrastructure
Application-level protection
Automatic and within seconds failover during unplanned outages
No downtime during planned maintenance
Performance sensitive app
DR required for compliance regulations
Solution
HADR with Always On Availability Groups on Linux or Windows
Native clustering integration (Pacemaker)
Backups
Reports HA DR
Async Log Synchronization
Sync Log Synchronization

8. Native integration with Linux cluster solutions
6/15/2018 1:36 PM
Native integration with Linux cluster solutions
Outside in integration with availability group
Open design to integrate with other cluster solutions
Cluster operations (i.e. failover) must be executed using cluster tools
3 synchronous replicas required for automatic failover
Some limitations exist
Cross platform
Cloud
Containers
Pacemaker/Other cluster solutions HA DR
Availability Group

9. Demo Setup 3 nodes availability group
Add AG as a resource in the cluster
Automatic failover with application recovery

10. Mission Critical HA on any platform
Scenario
Enterprise moving to an all-Linux infrastructure
Rigorous business requirements
Seamless migration
Solution
Minimum downtime and HA for cross- platform migrations with Distributed Availability Groups
Enables upgrading AGs from 2016 to 2017
Distributed Availability Group
AG2
AG1
Migration/Testing

11. Flexibility of HADR infrastructure
Scenario
ISV solution built on SQL Server on Windows
Linux certification
Solution
Cross platform hybrid availability group
Enables DR/testing/migration – fast data replication and minimum downtime
Cost effective – hybrid with Azure replicas
Availability Group
DR/Migration/Testing

12. Demo Create Windows/Linux availability groups (cluster type NONE)
Automatic seeding
Manual failover

13. Scale with read only secondary replicas
Async Log Synchronization
OLTP workload

14. Scale with Distributed Availability Groups
Async Log Synchronization
AG2
Distributed availability group

15. Offload backups to secondary replicas
Async Log Synchronization
OLTP workload

16. Demo Create availability group in Windows (cluster type NONE)
Run analytic workload on secondaries
Scale out by adding additional replicas

17. Other Availability Groups enhancements
Scenario
Cross database DTC transactions
Application uses multiple databases within same server
Databases are part of an availability group
Ensure at least one failover target available
Mission critical application cannot tolerate prolonged downtime and/or data loss
Secondary replica disconnected before primary outage
Solution
Enhance DTC support for Always On Availability Groups: within and across instances
CREATE AVAILABILITY GROUP MyAG WITH
(DTC_SUPPORT = PER_DB)
New required_synchronized_secondaries_to_commit for maximum high availability and data protection
CREATE AVAILABILITY GROUP MyAG WITH (REQUIRED_SYNCHRONOUS_SECONDARIES_TO_COMMIT= 1)
