IaaS, SQL, REST and Powershell

Why is IaaS useful and what can do with it

Introduction

AgendaIntroduction to IaaSSimple IaaS patterns for the EnterpriseSQL Server and IaaSDeploying via PowershellDeploying using RESTScripting updates to your VMSQL and High Availability in the Cloud

WhoRichard Conway (and Andy Cross), co-founders UK Windows Azure User Group and need to use this cache in their own application and will explain why!

What is IaaS?

IaaS is…

• By Definition and Function• Infrastructure as a Service• Permanent VM Roles (with a lot less hassle!)• A way of extending your windows network into the cloud securely• A way of migrating your existing application and processes into the cloud• A way of doing what you do on premise without large capital investment and

scaling to meet your needs quickly

• What can you do• Build a web farm• Build a Windows network• Build a virtual datacentre• Build a set of virtualised desktops to offload complex tasks (e.g. rendering)• Basically, building applications and entire organisations in the cloud!

Installing a SQL VM via Powershell

Types and info on caches

Recap of demo• Download and install WAPP CmdLets• Download a .publishsettings file• Use Import-AzurePublishSettingsFile CmdLet• Use Set-AzureSubscription or Select-AzureSubscription to set the

correct subscription• To see a list of gallery and saved images Get-AzureVMImage• You need to specify an image name, a cloud service name, a machine

name, a VM size, a Windows password and a location• Use New-AzureVMConfig to provide the config, Add-

AzureProvisioningConfig to add the Windows provisioning, Add-AzureDataDisk to add an additional disk, Add-AzureEndpoint to setup an Azure endpoint on 1433

• Use Get-AzureDisk | Select DiskName and Remove-AzureDisk –DiskName –DeleteVHD to remove

What to do after an install …

• Remote desktop on to the machine• Update the SQL Server to use Mixed Mode authentication• Create and login and user with a password• Add the user to the dbowner role• Open an incoming port on the firewall to allow access to port 1433• Open up SSMS• Enter the credentials to the DNS endpoint • Login and manipulate the database• Take all of the above and script into a powershell script!

Deploying a SQL VM in C#Using Fluent Management

Simple Fluent Syntax

var manager = new SubscriptionManager(TestConstants.InsidersSubscriptionId);manager.GetVirtualMachinesManager() .AddCertificateFromStore(TestConstants.ManagementThumbprintIaaS) .CreateVirtualMachineDeployment() .AddToExistingCloudServiceWithName(TestConstants.CloudServiceNameIaaS) .WithDeploymentType(VirtualMachineTemplates.SqlServer2012) .WithStorageAccountForVhds(TestConstants.StorageServiceNameIaaS) .WithVmOfSize(VmSize.Small) .Deploy();

What the REST request is composed of …

• Deployment• RoleList• Role

• ConfigurationSet• Windows

• Domain Join• Certificates

• Linux• SSH

• Network• Endpoints

• Endpoint• Loadbalancer

• Subnet• Availability Set• DataDisks• DataDisk

• OS Disk• Role Size• Virtual Network• DNS Servers

POST https://management.core.windows.net/<subscription-id>/services/hostedservices/<service-name>/deployments/

Requests are asynchronous so you need to poll for success with the “x-ms-request-id”

https://management.core.windows.net/%3Csubscription-id%3E/services/hostedservices/%3Cservice-name%3E/deployments/

Best Practice GuidelinesSQL Dos and Donts

SQL Performance Best Practice

• From the SQL Server team!• Test performance with SQLIO (test the underlying storage

subsystem)• Use Storage Analytics as a free download to see the underlying

storage transactions• Don’t set max memory let SQL Server handle this • Disable write caching for the OS• Move the data and logs off the OS Disk preferably onto

separate drives• Use the volatile D: drive for tempdb storage• Use page compression to reduce IO
