SQL Server on Linux CTP 1.1 Florian Mader @flomader

Our Sponsors If you think, that a SQL Saturday is a nice possibility to learn from and network with fellow SQL Server enthusiasts FOR FREE, I just ask you one thing: Visit the sponsor booths and chat with the sponsors! They are covering the expenses for each and every of you, with is around EUR 60 …

Agenda Quickstart Supported Platforms & Features Platform Abstraction Layer Performance SQL Server on Linux HA SQL Server on Linux & Docker

Quickstart Requirements How? docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=<YourStrong!Passw0rd>' -p 1433:1433 -d microsoft/mssql-server-linux Requirements Same high quality & security standards Same value in terms of functionality and scale Application compatibility between SQL Server on Windows and Linux Features and fixes need to appear immediately across platforms Lay a foundation for future SQL Server suite services (SSIS) How? Same high quality code across OSes Enabled through Platform Abstraction Layer (PAL)

Supported Platforms & Features Ubuntu 16.10, Ubuntu 16.04 LTS and earlier Red Hat Enterprise Linux 7.3 Workstation, Server, and Desktop and earlier Docker Engine 1.8 and later Features Core Database Engine Including CLR, In-Memory OLTP, Columnstore Index, Query Store, DMV Tooling Administration: SSMS, mssql-conf, Powershell Development: SSMS, Visual Studio Code, SSDT, Connectivity libraries (C#, Java, PHP, Node.js, Python, Ruby, C++)

Unsupported Features (CTP 1.1) Database Engine High Availability Security Services Full-Text Search Always On Availability Groups Active Directory Authentication SQL Server Agent Replication Database Mirroring Windows Authentication SQL Server Browser Stretch DB Extensible Key Management SQL Server R Services Polybase Use of user-provided certificate for SSL or TLS StreamInsight Distributed Query Analysis Services CLR assemblies with the EXTERNAL_ACCESS or UNSAFE permission set Reporting Services Filetable Integration Services System extended stored procedures (XP_CMDSHELL, etc.) Data Quality Services Master Data Services

Platform Abstraction Layer Goal Remove or abstract away SQL Server’s dependencies on Windows Dependencies “Win32” (ex. user32.dll) NT Kernel (ntdll.dll) Windows application libraries (such as MSXML, MS DTC, ) SQL Server Operating Systems (SOS) Resource management Improved performance Supportability Not a full abstraction layer Drawbridge Microsoft Research Project reducing the virtualization resource when hosting many VMs on the same hardware user mode Library OS (LibOS) 1500+ Windows ABIs in user mode SOSv2 SOS and LibOS merged 81 MB of uncompressed Windows libraries, SQL PAL itself ~8MB

SQL Server on Linux HA Failover Cluster Instance on RHEL 7.3 based on Red Hat Enterprise Linux (RHEL) HA add-on Uses Corosync and Pacemaker Currently only high-level functional testing, not a production setup Linux Server 2 Linux Server 3 SQL Server 1 SQL Server 2 Pacemaker Corosync Linux Server 1 NFS

SQL Server on Linux & Docker Requires 4GB RAM Runs on Docker for Windows & Docker for Mac Demo
