Where the Cloud is Compelling

App Characteristic Example

Massive scale Outback promo on Facebook

High reliability eCommerce apps (Coke, Dominos)

Variable load Online tax preparation (CCH)

Unpredictable lifetime Hurricane relief site

Requiring parallel processing Genome sequencing

Scale fast or fail fast Web sites (Kelley Blue Book)

Not good fit for in-house data center Frequently updated app

Needing external storage Online video archive

No desire to manage infrastructure SaaS apps (Quark’s Promote app)

Windows Azure Cloud Fabric

• Multiple virtual instances• Easy provision of applications• Detect failures• Spin up new instances to replace the failed ones• How many instances and what role they will play• Load balances and DNS• Elasticity of the service… scaling up/down number of instances

Windows Azure Features

ComputeDatabaseStorageCDNVirtual NetworkMarketplace

Compute

• Windows Azure provides developers an internet-scale hosting environment with a runtime execution environment for managed code.

• Administration

Windows Azure automatically takes care of things such as load balancing and failover thereby reducing the effort and cost of administering the application environment• Availability

designed to let developers build applications that are continuously available, even in the face of software upgrades and hardware failures

Compute (cont..)

• Scalability

Windows Azure enables developers to build scalable applications that run in Microsoft’s global data centers. Just as important, it allows developers to scale down applications when necessary, letting them use just the resources they need.

Windows Azure Roles• Web Role

– for web application programming in ASP.NET or PHP• Worker Role

– is used for generalized development, and may perform background processing for a web role.

– may be written in .NET, Ruby, Java– to improve scalability by increasing parallelism and

asynchronicity

Developer Experience

• Leverage Existing Skills in .NET, SQL Server, WCF• Use Familiar tools – Visual Studio, SSMS• RESTful HTTP cloud services, supports PHP,

Python• Cloud apps can be developed locally / offline• SDK Cloud Simulator – Dev Fabric, Dev Storage

The Windows Azure SDK

Storage

• Blobs – Large Data Store• Queues – Background work processing• Tables – Very Fast / Scalable Storage• Drives – NTFS Formatted Page Blobs • SQL Azure – Relational SQL in the Cloud

Microsoft® SQL Azure• Is a highly available, and scalable cloud database

service.• Built on SQL Server technologies• High availability and fault tolerance is built-in and no

physical administration is required.• Create, access, and manipulate tables, views, indexes,

roles, stored procedures, triggers, and functions.• Insert, .Update, and Delete.• Integration with SQL Server and tooling including Visual

Studio®• No physical administration required – software

installation and patching is included, as this is a platform as a service (PAAS)%

Programmability and Tools

• Managed ADO.NET data access• Native ODBC• Support for PHP• JDBC Support

Tools• SQL Server Management Studio: an integrated

environment with graphics tools for accessing• SQL Azure Database account portal• Visual Studio 2010 cloud toolkit.

Windows Azure SDK Features

• C# and VB Visual Studio project templates– Windows Azure Cloud Service solution with multiple roles.

• Tools to manage and configure roles• Local Development Fabric• Local Development Storage services• Local Cloud Service debugging support• Cloud Service package and deployment builderNote:• No SDK Required for SQL Azure

Windows Azure Virtual Network

• Windows Azure Connect provides a simple and easy-to-manage mechanism to setup IP-based network connectivity between on-premises and Windows Azure resources.

• Migrate their existing applications to the cloud by enabling direct IP-based network.

• Simple for developers to setup direct connectivity to their cloud-hosted virtual machines.

• Enabling remote administration and troubleshooting

Windows Azure Marketplace

• An online marketplace for developers to share, find, buy and sell building block components.

• An Applications section - includes finished applications, service templates and building block components• DataMarket section - include data, imagery, and real-time web services from leading commercial data providers and authoritative public data sources such as demographic, environmental, financial, retail, weather and sports.
