• 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 – 7th year

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

Enhanced High Availability

• AlwaysOn Enhancements• Online Database Operations

Hybrid Scenarios

• Smart Backup• AlwaysOn Replica in Windows Azure VM• SQL Server with Azure Storage Integration• On-Prem to Azure Migration

Other

• Separation of Duties• Extending PowerView• Windows Server Enhancements

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

BP & S: Columnstore

• New clustered option• Completely read/writeable• New archive option for even more compression

BP & S: Query Performance Improvements

• New cardinality estimator• Incremental statistics per partition

BP & S: Resource Governor

• Limit I/O to a Resource Pool• Limit CPU usage; percent, affinity• Limit DOP• Limit Memory

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

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

HA: Online Operations

• Single partition online index rebuild• Manage lock priority for SWITCH and online index

rebuild operations

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

Hybrid: Backup to Azure Storage

• Near-bottomless storage• Offsite, geo-redundant• No provisioning• No device management• No media decay• Remote accessibility

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

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

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

Other: Separation Of Duties

• CONNECT ANY DATABASE• IMPERSONATE ANY LOGIN• SELECT ALL USER SECURABLES• Allows for greater role separations – audit vs

admin

Other: Power View for Multidimensional Models

• Allows native support for DAX in Analysis Services• via BI Semantic Model

Other: Windows Server Enhancements

• ReFS Support• Online resize VHDX• Storage Tiering• SMB improvement• Hyper-V replica improvement• Faster live migrations
