Imagine you want to…

Move to the public cloud with your appGlobal scale, new customers / reach, dealing with peaks and growth

You want to get max of the advantages of the cloudSimplest possible scale, automated operations management, no manual processes

But: parts of your app do have special requirementsLegacy components, special SQL Server functionality, other OS platforms (e.g. Linux, Oracle)...

Starting Point – Decision to go Cloud

You are a software vendor (ISV)Web-based software product

Data is partially sensitive (personally identifyable)

Generating lots of documents in the background

You are local leader – global growth desiredGrowth on the local market is limited

Business goals from the CEO: Growth to US and APAC

No resource for HW/SW investmentsYour budget for additional hardware and software is limited, nevertheless

Current Application Architecture

Web Server

ASP.NETMVC App

DocumentGeneration

Service

SQL Server Cluster

SQL Server Cluster

Storage Cluster System

Your decision for Windows Azure

Primary reason: Platform-as-a-ServiceFast and flexible scaleability

Lowest-possible effort for managing the deployments

Options for PaaS in Windows AzureCloud Services = highly scalable multi-tier applications

Web Sites = scalable web applications with database backends

Mobile Services = scalable backend framework for mobile apps (tablet, phone)

Globally available data centersEurope 2x, USA 4x, Asia/Pacific 4x, China 1x, Austrialia 1x – continous extension

Analyzing the application architecture...

Web Server

ASP.NETMVC App

DocumentGeneration

SQL Server Cluster

SQL Server Cluster

Storage Cluster System

Analysis Results for this example...

Web application:Is stateless and manages sessions through ASP.NET state provider

Must be able to scale extremly fast

Document generation runs async in the background

SQL Server Cluster:SQL Server 2008 R2 with latest service packs

Usage of SQL Server Encryption for sensitive data

Storage ClusterHighly available storage system used as network file share

Results for the architecture on Azure:

Results for this example in Azure:

Web App & Document Generation ServiceWindows Azure Cloud Services

Enables Web App & Backend Service in one deployment package

Web Role for the web app as front-end

Worker Role for the document generation in the backend

AutoScaling possible (since mid 2013)

Database backend systemSQL Server 2008 or 2012 in Windows Azure Virtual Machines

Enables leveraging full feature-set of SQL Server

Disadvantage: you have to do the operations management for your VM

But: management can be automated through PowerShell Scripts

Implementing a PaaS/IaaS Mix

Networking & CommunicationsCreation of a Windows Azure Virtual Network

Enables „private“ communication between Virtual Machines & Web/Worker Roles

Deploy and configure VMs in AzureOperating database with full SQL Server in Windows Azure

Configuration of Firewall Rules, Ports, disks etc. necessary

Develop and connect the Cloud ServiceWeb-Role for the web front-end tier in our example

Worker-Role for operting the document generation service

Deploy and configure VMs in Azure

99.95% SLA be sure you have 2+ VMsSQL Server AlwaysOn Availability Groups are fully supported (since GA 2013)

SQL AlwaysOn Availability Group Listeners are fully supported (since 09-2013)

Data Disks and SQL Server in VMsEach data disk has ~500 IOPS

Store logs and data files on separate data disks

Use SQL Server files and file groups or storage pools to distribute load

DON‘T use RAID striping!!!

Options for SQL Server „licensing“Bring your own SQL license

Alternative: use per-hour billing by selecting images from gallery

Cloud Services – Important Details

Highest degree of elasticity & scaleScaling through portal, management API or AutoScale (!!)

You focus on app package and logic, not infrastructure

OS and hosts are fully automatically managed

e.g. automated Windows Updates, app-updates without downtime etc.

But – be prepared for that automationRound-Robin Load Balancing, automated start/shutdown of instances…

SLA – 99.95% ensure 2 instances / role

In Summary

VM / Cloud Services Mix Deployments

Mixed cloud app = IaaS + PaaSParts run in Platform-as-a-Service, others in Infrastructure-as-a-Service

„Private“ communication via virtual networks

Cloud Services (Platform-as-a-Service)Whatever possible do in PaaS and not IaaS!

Fastest scale, lowest operations management overhead

Virtual Machines (Infrastructure-as-a-Service)You do have full control of the VM

Optimum for components with lots of customization efforts etc.

More Use Cases for PaaS/IaaS-Mix

Linux-based ComponentsThese run in Azure VMs (CentOS, SuSE, Ubuntu, Oracle Linux)

Real world stuff: Linux-based video encoder of partner, partner in Spain with MongoDB in Linux

Special SQL Server requirementsSQL Server in VMs whenever Azure SQL DB cannot be used

Real-world sample: SQL CLR usage of a partner in Austria, high-memory DB requirements

Oracle Database is neededOfficially supported backed by announcement in June 2013

Oracle DB on linux is GA and supported, Oracle DB on Windows is in Preview
