Portfolios, Add Technical Value

with the Windows Azure PlatformThree Case Studies for Technical Decision Makers

This white paper describes how Microsoft system integrator partners are using

Windows Azure, an Internet-scale cloud services platform that is hosted in

Microsoft data centers, to develop applications and services that are quick todeploy, easy to manage, readily scalable, and competitively priced.

Because the Windows Azure platform handles the deployment and operations

infrastructure, partners can extend their reach into new markets while staying

focused on the bottom-line business value of customers IT investments.

The Windows Azure PlatformThe Windows Azure platform is an Internet-scale cloud services platform hosted

in Microsoft data centers that offers virtualized computing power, storage,

monitoring, and automated management for

applications and services.

Although the platform provides specific add-ins

and tools for the Microsoft Visual Studio 2008

development system, Windows Azure is an open

environment that enables developers to

continue to use familiar Microsoft and non-

Microsoft languages, tools, and services.Windows Azure supports .NET, SOAP, REST,

XML, Eclipse, Ruby, PHP, and Python, helping

developers integrate a broad variety of

applications with minimal effort.

Windows Azure for System Integrators

The Windows Azure platform provides readily scalable processing power and

storage, along with tools and services that support dynamic capacity adjustment,

load balancing, and failover, on a pay-as-you-go basis.

With Windows Azure, system integrators (SIs) have the infrastructure they need

to develop cloud-based applications and service offerings. SIs can more readily

offer their clients options for moving all or part of on-premises applications to

the Web, for extending existing applications functionality with new Web-based

features, and for enhancing current on-premises operations with the benefits of

software-plus-services.

Using Windows Azure, SIs can extend the scale and reach of their services

without huge capital outlay or significant increases in logistical staff. They benefitfrom new consulting opportunities and associated revenue streams offered by

the cloud computing environment. SIs can concentrate on designing and building

applications and services that their clients need without committing resources to

the operational tasks involved in deploying, managing, and hosting those

services themselves.

Windows Azure is an open

platform that adds

support for non-Microsoft

developer tools and

technologies to its solid

foundation in Visual

Studio 2008 and the .NETFramework.

The following case studies illustrate how three Microsoft system integrator

partners, Avanade, CSC, and Infosys, are using the Windows Azure platform to

expand on and streamline service offerings.

Avanade: High-Volume Applications from

Enterprise to WebAvanadewhich is majority owned by Accentureconnects insight, innovation,

and expertise with Microsoft technologies to help customers realize

results. As early adopters of Windows Azure, Avanade developers

immediately saw the value in moving high-volume, on-premises

applications that are characterized by unpredictable surges in traffic

to the cloud.

Accenture and Avanade produce industry solutions such as online

banking, e-commerce, and media production. Predicting demand,

and therefore the required IT capacity for these sorts of services is

difficult. The tendency is to overprovision data center capacity to

support strict service level agreements (SLAs). But this leads to

extended periods where data center resources are idle and

operations overhead is correspondingly high; in this environment,the cost to serve can be artificially inflated. On-demand scalability

with the Windows Azure platform provides an advantage in this scenario by

offering the ability to bring additional instances of processing applications online

or take them offline as required by variability in demand. Avanade developers

demonstrated how the companys applications for media processing, ticketing ,

and publishing would benefit from the flexible scaling options available through

the Windows Azure platform.

Developers also identified another more purely logistical advantage to moving to

the cloud: They could build Windows Azure applications that were functionally

equivalent to their on-premises versions, from standardized and shared source

components. Doing so increases efficiency throughout the development, test,

and build processes. They can then migrate all or part of their applications to

Windows Azure with minimal forking of a single code base, from which they can

build both on-premises and cloud-based editions of their applications.

Moving to a Distributed Processing Model

Avanades applications were primarily three-tier architectures that relied more on

multithreaded local processing than a distributed processing model. The mediaprocessing and ticketing projects share a common requirement of applications

that Avanade plans to move to Windows Azure: They need to respond with

predictable performance and cost to unpredictable fluctuations in demand.

Developers decided on a phased migration approach to the Windows Azure

platform. Early phases would first divide application tasks into local front-end job

scheduling and remote compute-heavy processing before the tasks would be

migrated to the cloud. Subsequent phases would move more of the front-end

components into Windows Azure, along with operations and management

support such as rich-event and performance logging.

A first step was to use the Windows Communication Foundation (WCF) to move

the processing portion of a multithreaded local processing model into

cooperative Web services that can then be readily hosted in Windows Azure.

For Avanades media encoding and publishing application, this meant that tasks

were handed off to the cloud, where worker roles could be brought online to

service batches of up to 20 or more encoding requests for each media stream.

For the ticketing and online reservation system, Accenture hosts the back-end

business logic locally and utilizes the Windows Azure service to handle

unpredictable surges in consumer traffic. User interface and data presentation

functions are unchanged, but services such as user authentication, data storage,

and event logging can be moved to the cloud.

Design Points

Developers at Avanade noted that services on the Windows Azure platform must

be strictly statelessmeaning that the distributed processing features of

Windows Azure services cannot maintain state across requests. This required

some changes to the stateful on-premises model, but it is a common

requirement for Web services and a best-practice for developing WCF

applications.

Moving to a cloud-based infrastructure such as Windows Azure is seldom an all-

or-nothing process. Avanades experience is that software-plus-services

applications, in which portions of the application remain on-premises while


6/15

6 | P a g e

(typically) compute-intensive or resource-intensive functions are moved to the

cloud, often make the most sense. Part of the design process is finding the

balance point that makes most logistical and economic sense for the specificapplication and its customer deployment.

A further consideration was operations. Customers are used to monitoring

applications from their on-premises operations consoles, where they now need to

see the performance of their cloud-based services. Developers plan to integrate

performance data from Windows Azure into local operations functions so that

customers can more easily maintain a holistic view of their IT investments.

Avanade is developing dedicated Windows Azure skills now while also identifying

common patterns and practices that will speed clients future adoption of servicesbuilt on the Window Azure platform.

CSC: Legal Solutions SuiteCSC provides a mature suite of applications for the legal and claims industries

including Legal Solutions Suite (LSS). Currently hosted onsite at customer

locations or in CSC data centers, Legal Solutions Suite is poised tooffer a

business service based on the Windows Azure

platform.

A key consideration for CSC in developing an

application for Windows Azure was expanding

its corporate services penetration in both

domestic and international markets. The

expanding network of Microsoft data centers

offers greater potential for global reach with

applications and services written for Windows

Azure and for isolation from scalability issues as demand grows. CSC anticipates

significantly reducing the lead time required to provision the solution, thus

accelerating time to production. And by using the Windows Azure platform, CSC

will be able to increase capacity almost instantaneously. Alongside the added

capacity, the Windows Azure platform provides high availability through

automated load balancing and redundancyimportant features that are costly to

firms to help simplify the

deploy and manage in-house or as options from a conventional hosting service

provider.

CSC developers were already familiar with Microsoft development tools and the

Microsoft .NET Framework; the existing LSS application is built on the .NET

Framework version 3.5, so portions of the code could be easily ported to the

Windows Azure platform. Other components needed to be

redesigned to take advantage of the functional division

between Web roles and worker roles in Windows Azure.

Breaking Down the Migration Task

LSS comprises three major components that handle Web

server, data access and consolidation, and data processingfunctions.

For the Windows Azure deployment, LSS developers created

two Web roles to handle HTTPS communications and

business logic, and one worker role to perform

asynchronous processing and data storage and retrieval

tasks. The number of instances of concurrent roles can then

be increased or decreased to meet current capacity

requirements.

For the initial release to the Windows Azure platform, CSC developers decided to

implement core features of the current version of LSS. However, some LSS

features are planned for a subsequent release, such as those that interface with

external components, including CSCs claims management system for the self-

insured market, Riskmaster X, and Data Exchange Web service. When migrated,

these external components will implement WCF interfaces, which can be readily

deployed in Windows Azure.

Some additional design changes needed to be made to their application toprepare existing functionality for deployment on the Windows Azure platform.

Windows Azures stateless model means that cached data can no longer be

stored in memory because it may be serviced by multiple instances of an LSS role.

Instead, data is written to Windows Azure storagea slight trade-off in

performance compared with local on-premises storage that buys a big advantage

in scalability and availability.

For event and error reporting, LSS

components must now use Windows Azure

agents. Local system files and event logs are

no longer available in the virtualized

Windows Azure environment.

To keep LSS e-mail alerts running in Windows

Azure, which does not offer an SMTP service,

LSS developers routed messages through

port 25 to use an external SMTP relay.

To help optimize performance, developers decided to take advantage ofaffinity

groups in Windows Azure. Affinity groups help achieve high bandwidth and low

latency by specifying not only the geographic location of the hosted services but

also collocation for services and their related data storage.

Experience So Far

CSC developers took advantage of Windows Azure tools for building, debugging,

and deploying to Windows Azure directly from their existing development

environment. As a result, developers were comfortable with an aggressive

schedule that enabled them to design, develop, test, and publish a solution

hosted on Windows Azure within their normal annual product release cycle. In

addition, the LSS transformation to the cloud used CSCs existing software-as-a-

service business and technical framework to accelerate overall project timelines.

CSC has made a considerable investment in cloud services, including the creation

of an Azure Competency Center for Windows Azure Development. The company

is preparing LSS for production in its competency center in Vietnam, and

anticipates further expansion in Asia and to the United Kingdom. CSC expects tooffer more of its financial services applications on the Windows Azure platform in

the future.

CSC believes that moving

to Windows Azure will give

it a significant competitive

advantage with its Legal

Solutions Services product.

Infosys: mConnectInfosys offers mConnect, a product that enables Web sites, e-commerce, and

banking platforms to support mobile devices without costly modifications to their

services. Infosys mConnect middleware abstracts the variety and complexity of

current and future mobile devices, identifies device and network capabilities, and

presents requested data to users in the most appropriate and effective way.

mConnect overcomes major challenges to the distribution of content on mobile

devices, isolating content provisioning from the diversity of devices, browsers,

mobile applications, and network technologies. And mConnect is fully extensible,

so that support for new application capabilities and devices can be brought

online quickly and efficiently.

For Web sites and e-commerce providers, the value is simple: a device-agnostic

process of building applications that offers a standardized context regardless of

how data is ultimately presented and consumed.

mConnect is a successful on-premises product. In order to best offer mConnect

in a hosted, multitenant environment, Infosys decided to take advantage of the

pay-by-use model offered by Windows Azure. Windows Azure provides increased

scalability and improved performance without high upfront investment, helping

mConnect efficiently meet the huge demand of business-to-consumer mobility

services. The Windows Azure platform handles computation and Web-facing

workloads, while Microsoft SQL Azure provides data storage, simplifying

provisioning and deployment of databases that benefit

from enterprise-class availability and built-in data

protection.

Putting Language Interoperability to the Test

mConnects platform was originally built on a J2EE

platform and can work with almost all relational databases

for data storage. An attractive benefit of the move to

Windows Azure was the increase in scalability gained by

utilizing SQL Azure while maintaining the applications

existing relational data handling functions. One of the key

mConnect from Infosys

provides a rich customer

experience, rapid support

for new devices and

services, and can be

integrated with anyexisting back-end

a lication.

implementation objectives was to accomplish

the migration to Windows Azure in weeks rather

than months and to avoid rewriting large partsof the application, which were already well

tested.

Migrating the data repository to SQL Azure was

straight forward: Developers used Microsoft SQL

Server Integration Services tools to help build

packages that would migrate data from on-

premises databases to SQL Azure. But the Java-

based application components required more

thought because they could not be hosted

directly as a service in Windows Azure.

Interoperability, though, is key to Windows Azure, and Java-based applications

and services can interoperate with components of the .NET Framework in

Windows Azure as long as they do not require elevated privileges (such as are

required to write directly to the registry or to access system folders). Infosys

developers created a specialized Windows Azure worker role under the .NET

Framework for the service endpoints; at service startup, the worker role deploys

and configures the required J2EE Web server and infrastructure and then deploysthe mConnect package above it to start the mConnect engine. Because the

application was already using the Java runtime in the Azure worker role, no

changes were required to the application code itself. By adopting this least-

invasive approach to application migration, Infosys was able to run a Java-based

package deployed and served from the Windows Azure platform. Thus, the

company gained the required scalability and reliability it needed from the

platform along with an overall fast time-to-market.

Future Directions

The Infosys mConnect experience is an example of a relatively straightforward

migration of a legacy application to cloud-based services. Developers are

confident that they can deploy any of their Java-based application packages in

Windows Azure with minimal changes and few, now well-understood, new

components.

With Windows Azure, you

really don't have to go

outside and ask for

infrastructure; therefore

your ability to deliver

solutions becomes much

faster. You can really

innovate and be

competitive.

Infosys is looking at other creative ways to add the value of

its Windows Azurebased mConnect service to existing on-

premises applications such as Interactive Voice Response andIP-based television. The scalability and ubiquity of Windows

Azure applications is a natural fit for mConnects

multichannel, multiple-device capabilities.

But there are also scenarios where on-premises applications

that use the .NET Framework can make some or all of their

functionality available to Windows Azure by exploiting the

interoperability WCF. For the future, Infosys sees a productive interaction

between cloud-based and on-premises applications as they take advantage of

the commonality between local and Web-based programming and deployment

environments. Customers could be offered the ability to run almost any

application both on-premises and as a service published to Windows Azure,

depending on their current business requirements.

ConclusionA common thread among the experiences of these Microsoft SI partners is that

Windows Azure solutions are a key addition to their services portfolio, enabling

them to offer their clients a broad range of options for taking advantage of

cloud-based services.

Windows Azure is a flexible environment, offering SIs a great response to

customer scenarios that can take advantage of the scalability and the cost-

effectiveness of moving all or part of the solution to the Web. In some cases, key

functionality can be migrated to a cloud-based service, while the bulk of the

application remains on-premises. The windows Azure architecture also enables

complete applications to be recast as services, removing the requirement for on-

premises equipment and operations.

Development is supported by a rapidly maturing tool set, based on familiar

Microsoft programming environments and a comprehensive SDK. A base level of

support for non-Microsoft software and runtime environments is enhanced by a

growing amount of community experience in migrating diverse deployment

configurations to the Windows Azure platform.

Windows Azure supportsxcopy deployment for

applications that require

otherwise unsupported

runtime components.
