AlwaysOn: Objectives• Increased availability• Improved hardware utilization• Simplified administration
AlwaysOn: AvailabilityInstance Availability Database Availability
AlwaysOn: Instance Availability• Enhances Windows Failover Clustering
with:– Enhanced diagnostics– Flexible failover policies– Easier multi-site clustering
AlwaysOn: Health & Diagnostics
Five Resource Types:• System• Resources• Query Processing• IO Subsystem• Events
AlwaysOn: Failover PoliciesCondition
Policy Number0 1 2 3 4 5
Windows Service Down • • • • •Cannot Obtain Health • • • •System Reports Error • • •Resource Reports Error • •Query Processing Reports Error •
AlwaysOn: Multi-Site Clustering• Multi-site clustering supported since 2005
– VLAN required between sites– Storage-level replication separate from SQL Server
• Multi-subnet support with 2012– Storage-level replication still separate from SQL Server
DNS
Site A Site B
AlwaysOn: Database Availability• Enhances database mirroring with:– Multiple Secondaries– Availability Groups– Virtual Network Name– Readable Secondaries
AlwaysOn: Availability Groups• Multiple user databases in replicated set• Failover together within topology
AlwaysOn: Secondaries• 1 primary + up to 4 secondaries– 2 max synchronous secondaries
• Provide failover & automatic page correction• 1 secondary in automatic failover pair
AlwaysOn: Secondaries
AlwaysOn: Automated Failover
ConditionPolicy Number1 2 3 4 5
Windows Service Down ORAG Lease Expired • • • • •
Replica in Failed State • • • •System Reports Error • • •Resource Reports Error • •Query Processing Report Error •
AlwaysOn: Virtual Network Name• Virtual Network Name (VNN) established
with Windows Failover Cluster Services (WFCS)
• Availability Group Listener interacts with WFCS to identify primary Availability Group
• Applications connect to VNN or individual server names
Virtual Network Name
AlwaysOn: Readability• All secondaries support backups• 2 secondaries can be designated readable• Availability Group Listener can route read-
only workloads to readable secondaries– Routing list prioritizes secondaries– Application must specify
ReadOnly intent
Virtual Network Name
AlwaysOn: Administration
Windows Core Server Support
• Supports:– Database Engine– Analysis Services– Integration Services
Security: Contained DatabasesInstance
User
Login
Instance
User/Login
Useful in scenarios when need to move a database:• AlwaysOn• Application Development• Azure
Security: Contained Databases• Supports Windows & SQL authentication– Windows-only recommended for authentication
security & DoS concerns• Must be enabled at instance-level and
implemented for specific databases• Access to instance-level resources permitted– Database becomes partially contained– Partial containment monitored through
sys.dm_db_uncontained_entities & cdb_uncontained_usage event
Security: Contained Databases• Increased potential attack surface– db_owner, db_securityadmin, or users with
ALTER ANY USER permissions can grant access without knowledge of instance admins
• Drives security administration to multiple levels– DB-level logins can access other databases
through guest or corresponding logins or user-accounts
Security• BUILTIN\Admins & LocalSystem• Managed service accounts & virtual
accounts• Custom server roles
Security: Audit Improvements• Server-level audit available in every
edition– Database-level audit in Enterprise &
Developer only• Fail operation options for log failures• More information in audit logs• Audits can be defined with filters• sp_audit_write proc for custom audit
Resource Governor Enhancements
• Support for 64 resource pools• Hard caps for CPU usage– CPU does not wait for contention
• Resource pools can be assigned affinity for specific schedulers or NUMA nodes
Performance Improvements
• Full-text search– Fully integrated with database engine– Improved query optimization & parallelism– Versioning to improve concurrent reads &
writes• Spatial indexes– Numerous improvements to indexes– Helper procs for easier index tuning– Support for row and page-level compression– Query plan optimizations
Performance Improvements• Expanded online operations– Add a non-nullable column with a
default– Index rebuilds support BLOBs
• Support for 15k partitions– Back ported to SQL Server 2008 & 2008
R2• Columnstore indexes!

Columnstore Index Execution Plan
With Columnstore Index
Without Columnstore Index
Columnstore Index Scan• Scans required index columns• Optimized for batch retrieval
– Retrieves ~1,000 rows per batch– Batches proceed to subsequent filtering
Batch Hash Table Build & Hash Match• Multiple filtering values organized as hash table• Hash table applied to index scan batches

Programmability Enhancements• Pagination in ORDER BY clause
Programmability Enhancements• Windowed operations in OVER clause– Enable moving averages, running totals,
etc.
Programmability Enhancements• THROW statement• FORCESEEK & FORCESCAN table hints– Back ported to SQL Server 2008 R2
Sequence Objects• Defined using:
– TinyInt: 0 to 255– SmallInt: -32,768 to 32,767– Int: -2,147,483,648 to 2,147,483,647– BigInt: -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807– Decimal: - 99,999,999,999,999,999,999,999,999,999,999,999,999 to
99,999,999,999,999,999,999,999,999,999,999,999,999 using decimal(38,0)• Bound by start, increment, min & max values• Cycle options for when range is exceeded• Created outside scope of current transaction
– Values consumed upon request• Caching available for performance
– Cache lost with system failure– Default cache of 50
• Retrieved using NEXT VALUE FOR or sp_sequence_get_range
