Phil Brammer Over 13 years’ experience in database technologies, data warehousing, ETL, on-call… Worked with Teradata at PayPal Operationally manages multi-terabyte instances Dabbles a bit in SSIS – ssistalk.com Microsoft MVP, SQL Server – 7 th year
3
Breakthrough Performance & Scale In-Memory OLTP (Hekaton) Columnstore Improvements Query Performance Improvements Resource Governor for I/O Buffer Pool Extension Scale Optimizations for > 8 socket systems
4
Enhanced High Availability AlwaysOn Enhancements Online Database Operations
5
Hybrid Scenarios Smart Backup AlwaysOn Replica in Windows Azure VM SQL Server with Azure Storage Integration On-Prem to Azure Migration
6
Other Separation of Duties Extending PowerView Windows Server Enhancements
7
BP & S: In-Memory OLTP Up to 20-30x throughput Easy to migrate existing applications Integrated experience Full ACID support All in-memory. No buffer pool, B-Trees No lock manager, latches, or spinlocks
8
BP & S: Columnstore New clustered option Completely read/writeable New archive option for even more compression
9
BP & S: Query Performance Improvements New cardinality estimator Incremental statistics per partition
10
BP & S: Resource Governor Limit I/O to a Resource Pool Limit CPU usage; percent, affinity Limit DOP Limit Memory
11
BP & S: Buffer Pool Extension Ability to extend buffer cache to any volume (SSD) Improve OLTP performance No risk of data loss (clean pages) Easy to implement
12
HA: AlwaysOn Enhancements Up to 8 readable secondaries Ability to use readable secondaries during network failures Cluster Shared Volume support Easier troubleshooting Wizard to add replica to Azure
13
HA: Online Operations Single partition online index rebuild Manage lock priority for SWITCH and online index rebuild operations
14
Hybrid: Smart Backup Input storage URL (Azure), retention Automatically backs up databases Automatically cleans up Context aware Minimal storage costs Zero hardware management No media decay
15
Hybrid: Backup to Azure Storage Near-bottomless storage Offsite, geo-redundant No provisioning No device management No media decay Remote accessibility
16
Hybrid: AlwaysOn Replica in Azure Wizard to add a replica in Windows Azure VMs Eliminates DR site needs (hardware, rent, etc…) Offload read/backup workloads
17
Hybrid: SQL & Azure Storage Integration Native support for SQL Server database files stored as Azure blobs Can move a single database at a time Save storage costs Backed by Azure Storage SLAs Fast disaster recovery using database attach Control security with on-prem model
18
Hybrid: Migrations to Azure VMs New Wizard to migrate databases to Azure VM Perfect for DBAs new to Azure No need of specific Azure knowledge Time to transfer DB is limiting factor
19
Other: Separation Of Duties CONNECT ANY DATABASE IMPERSONATE ANY LOGIN SELECT ALL USER SECURABLES Allows for greater role separations – audit vs admin
20
Other: Power View for Multidimensional Models Allows native support for DAX in Analysis Services via BI Semantic Model
21
Other: Windows Server Enhancements ReFS Support Online resize VHDX Storage Tiering SMB improvement Hyper-V replica improvement Faster live migrations
