  3. 3. Introduction The application hosting market is a lucrative business opportunity that is growing at a 22% annual rate, according to AMR Research. A significant number of small and medium sized businesses have already purchased web and email hosting services, while business email, online gaming, rich media applications, mobile solutions, software as a service, and collaboration are new applications that will continue to drive revenue growth. One example of the growth in the managed application market is the following chart on managed mes- saging: $4.500 $4.053 $4.000 $3.500 $3.464 $3.039 $3.000 $2.713 $2.500 $2.468 $2.000 $1.500 $1.000 $500 $- 2002 2003 2004 2005 2006 Figure 1: Radicati Group The maturity of the hosted application market helps customers hear about and recognize the benefits of outsourcing application management. This awareness has also made customers more discerning about purchasing services. Customers demand quick and infallible deployment, guaranteed service levels, and prompt delivery on return on investment promises. To meet these customer needs, application hosting companies need to deploy an infrastructure which is robust, yet flexible enough so providers can adjust their offerings to the constantly changing needs of the market. Tomorrow’s most popular application might be something that has not been deployed today. WIndoWs HosTIng According to the Radicati Group, Windows web, mail, data and application hosting is the fastest growing segment of hosting market, fueled by Microsoft’s efforts to reclaim market share lost to Linux. Parallels recognizes the Windows opportunity and has partnered with Microsoft in many capacities to further advance Windows application hosting. In this paper, we will address generic application hosting and use the Microsoft Hosted Messaging and Collaboration Platform (HMC) to provide specific examples of how Parallels System Automation can be used to help service providers offer Hosted Exchange and Hosted SharePoint solutions. © Parallels Powerful Application Hosting 3
  4. 4. Application Hosting Considerations There are fundamental differences between hosting an application and hosting a web site. When hosting an application, service providers need to consider the following: • Availability – Web site owners are less likely to accept downtime than they used to, but application owners require even higher availability. Application owners deploying mission critical applications require zero downtime. Even non-mission critical applications often require an infrastructure with can support “five nines” of reliability1. If you are deploying a mission critical or essential application, make sure that you deploy service clusters and hot backups. • Anticipated Response Time – Web site owners are able to accept brief delays in response time, but for some applications, even a 1-2 second delay may not be acceptable. Online gaming, real-time communications, and online auctions are examples of applications that require zero latency. • Configuration – Applications may require different types of configurations than web sites. One example involves packet arrival order or jitter. Web browsers have the ability to re-assemble packets so that packets can arrive in a different order than they were sent. Some applications may be sensitive to packet arrival order. Many of these types of applications may have to be configured with tunneling software on both the client and the server. • Scalability – As successful websites grow in size, customers can upgrade their hosting plan to include more server resources according to well defined and well understood plans. Unique applications may require their own specific upgrade path. For example, a database intensive application may function well on a freeware database until a lot of users join. When this happens, the only upgrade path might involve setting up a commercial database. CusTomer ConCerns Before making the decision to purchase or host an application, customers consider return on investment. Frequently customers compare the total cost of purchasing a single server and a single software application to the monthly cost of hosting the application without considering several of the hidden costs. Some of the frequently overlooked costs include: cost of redundant architecture for mission critical applications, network bandwidth, cost of 24x7 support, and the costs associated with upgrading the application technology every 3-4 years. 1 Refers to uptime of 99.999%. This is the equivalent of 5 minutes 15 seconds of downtime per year. © Parallels Powerful Application Hosting 4
  5. 5. Hosted Application: Business email Business email is an example of a hosted application that can be expensive to implement internally, so customers are willing to pay a hosting provider between $8 - $12 per user per month for this service. Business email delivers additional value compared with POP3 and web-mail: • 24 x 7 availability on redundant hardware • Shared calendaring • Shared contacts and distribution lists • Secure remote access • Mobile access using a handheld device The most common platform for delivering business class email is the Microsoft Exchange Platform. Micro- soft Exchange can be installed in-house (as is frequently done by larger organizations) or purchased from a hosting provider (as is frequently done by small and medium sized businesses). The size of the organization as well as the expertise within the corporation are important factors when customers determine whether or not they will purchase hardware, purchase licenses, install, maintain, and manage an Exchange Server. The graph below shows an example cost analysis of purchasing a hosted solution versus installing a solution in-house. The cost per month was determined by calculat- $30 ing the total cost over two years spread over 24 $25 Purchased months based on the following assumptions: $20 • Licensing costs provided from Microsoft Exchange web site. $15 $10 • Hardware costs: $4,000 Hosted $5 • A purchased, in-house solution requires ¼ of a full time support person to install $0 and manage. 100 200 300 400 500 600 As illustrated, companies with less than four Figure 1: Exchange Cost Per User (monthly) hundred users can save money by purchasing Hosted Exchange instead of installing their own server. Utilizing a hosted solution for business email will also free up technical resources. © Parallels Powerful Application Hosting 5
  6. 6. HosTed exCHAnge requIremenTs Launching Hosted Exchange requires several enhancements to the core Microsoft Exchange Server platform. Microsoft has combined with partners such as Parallels to help service providers deliver robust Hosted Exchange offerings. Several enhancements to prepare Exchange for hosting include: • Multi-tenant architecture: Service providers must be able to serve multiple customers from a single Exchange platform as provided by the Microsoft Hosted Messaging and Collaboration platform. Special provisions for scaling and reporting are included in the HMC software written by Microsoft’s hosting team. • Automated provisioning: Service providers can manually provision customers into Active Directory and Exchange or utilize a commerce web site to provision customers online. Parallels provides software which links a provider’s store front with Exchange using enhancements to the Microsoft Provisioning System (MPS). • Billing: Service providers can manually bill customers or build a billing system to link online customer orders with a customer credit card or manual collections process. Parallels provides a multi-tier billing system to support resellers and end users. • Customer Service: Service providers can field support calls and spend time asking customers about their problem, or login to a system as the customer to see what the customer needs. Parallels provides a way for support personnel to witness the customer’s experience, as experienced by the customer in order to reduce the cost of support. Frequently these support costs can be as high as $2 per customer per month. • Reporting and Branding: Service providers can sell directly or utilize resellers. Parallels supports multi-tier reporting and branding for service providers that want to establish a reseller channel. Branding is completely customizable, so that resellers appear to be independent entities. Microsoft and Parallels deliver these features in through the Hosted Messaging and Collaboration platform (Microsoft) and Parallels System Automation (Parallels). HosTed exCHAnge ArCHITeCTure Microsoft’s Hosted Messaging and Collaboration platform is a software package which includes Ex- change plus additional software required for deploying Exchange in a hosted environment. Parallels Sys- tem Automation provides the necessary billing and operational support processes and can be deployed directly on top of the Microsoft recommended architecture. Microsoft recommends a deployment architecture containing 24 required servers in order to offer a fully redundant Hosted Exchange offering. This architecture includes the 1 ISA server, 5 Exchange front end servers, 6 Exchange back end servers (storage), 4 DNS servers, 2 Active Directory servers, 4 provisioning servers (MPS, SQL), and 2 monitoring servers (MOM). Microsoft also provides a minimal architecture consisting of 5 servers to provide a non-redundant archi- tecture that has been tested up to 1,000 end users. This architecture consists of 1 Exchange front end server, 1 Exchange back end server, 1 DNS server, 1 Active Directory server, and 1 provisioning server (MPS, SQL). The diagram below illustrates a solution containing a full Exchange deployment and four Parallels System Automation servers. © Parallels Powerful Application Hosting 6

Parallels system Automation solution Parallels System Automation is an adaptive web and application hosting solution that provides complete support of the Microsoft platform technologies and applications. Parallels System Automation enables provisioning and management for providers, multi-tier reseller delegation and customer self-management for of any type of web or application hosting service. Parallels System Automation’s modular architecture allows specific deployment of business or operational components or Parallels System Automation can be deployed as a complete hosting solution including billing, marketing, provisioning, IT resource man- agement, and customer care. Parallels System Automation is manageable and cost effective enough to support market entry and scaleable and flexible enough to meet carrier-class and multi-platform de- mands. APPlICATIons HosTIng Parallels System Automation supports a wide variety of applications that run on both Linux and Win- dows operating systems. Unlike many operations support systems, Parallels System Automation enables service providers to package service offerings across operating systems on a single service plan. For ex- ample, a provider can offer a service plan with business class email on Microsoft Exchange, collaboration © Parallels Powerful Application Hosting 7

If a customer cancels their plan or doesn’t pay their bill, Parallels System Automation will automatically deactivate all of the customer services and increment that pool of available server resources. Parallels System Automation is built with a fully distributed architecture. This allows service providers to deploy applications on single purpose servers which are configured to the exact needs of the applica- tions that they support. The result is a highly scalable solution with maximum server density. In addition, a distributed architecture allows service providers to add new applications without impacting the service levels of existing services. Windows Hosting mICrosofT PArTnersHIP In 2004, Parallels and Microsoft entered into a joint agreement that outlines engagement for sales, mar- keting and engineering development. Of particular importance is the engineering development agree- ment. In order to fully support and implement Microsoft technologies, Parallels has access to relevant code and subject matter experts. Parallels has identified the following Microsoft technologies as focus technologies: Microsoft Hosted Messaging and Collaboration Platform (Active Directory Web-based Hosting), Exchange, SharePoint, SQL Server, Microsoft Operations Manager (MOM), Systems Manage- ment Server (SMS), MS DNS, Identity Integration Server 2003, ASP.NET security, and Shared Hosting Accelerator (including User Management, Blog, Photo Gallery, Forums, Nuke CMS, Guestbook, etc.). Parallels has or is in the process of incorporating the Microsoft focus technologies into its complete hosting product set. PArAllels sysTem AuTomATIon develoPmenT In suPPorT of HosTed exCHAnge Parallels System Automation delivers advanced management capabilities for the Microsoft Hosted Messaging and Collaboration Platform (HMC). Parallels built this functionality to assist service providers with hosting Microsoft Windows applications including Exchange, SharePoint, and SQL Server. Parallels System Automation provides provisioning, store front integration, customer friendly control panels, bill- ing support, reseller support, and trouble ticketing for a HMC deployment. Parallels System Automation adheres to Microsoft best practices and is tightly integrated with both Ac- tive Directory and the Microsoft Provisioning System (MPS). Customer orders and changes are entered directly into the Parallels System Automation web-based control panels and provisioned using MPS. In cases where MPS does not support features needed by web hosting providers, Parallels develops its own “providers” which accompany the standard providers issued by Microsoft and shipped with MPS. Parallels System Automation specific providers help users manage the following: • IP address configuration • NTFS disk quotas • Management of FrontPage server extensions • IIS SSL certificates • Windows SharePoint Services • ColdFusion • ODBC DSN • Windows Media Services © Parallels Powerful Application Hosting 8
  9. 9. Parallels System Automation supports all of the advanced features inside Exchange and allows providers to manage most of them at an individual mailbox level. Parallels System Automation also allows service providers to establish service plans with distinct resource amounts as illustrated in the diagram below. In the example above, the service provider created a stand alone Exchange service template with 10 mailboxes and 100MB storage limits. Although not shown here, the provider also established prices for extra resources so customers can upgrade their plan to have a 2GB mailbox. The customer can per- form this type of upgrade online, directly from the customer control panel, without contacting the service provider. The example above also demonstrates how providers can use Parallels System Automation to control customer access by mobile device, Outlook Web Access, IMAP4, and POP3. The provider can also establish how many distribution lists and shared contacts can be entered by the customer.

  12. 12. Application Hosting Benefits BenefITs for servICe ProvIders Application hosting allows service providers to increase revenue from their existing customer base and by acquiring new customers. Domain registrars, Internet service providers, and hosting providers with a large base of customers can offer new services at minimal cost by automating the storefront, billing, and provisioning processes using Parallels System Automation. After customers are enrolled, Parallels System Automation provides online upgrades and online marketing in order to increase revenue from an existing customer base nearly zero expense. There are many benefits for providers that choose to deploy Microsoft Windows application hosting using Parallels System Automation. Primarily, Parallels’ core business is to develop software solutions for web and application hosting providers. Parallels has an extensive team of engineers and is able to leverage development and expertise across hundreds of developers. Re-creating this level of expertise becomes cost prohibitive for service oriented organizations as additional technologies and new releases drive continual software maintenance and development cycles. Also, Parallels’ relationship with Microsoft and access to code and experts is very difficult to match. The combination of Parallels’ expertise and the Microsoft relationship provide a powerful software development combination. Parallels System Automation was designed to be the most flexible, distributed, and complete hosting solution platform available with the ability to integrate with existing or best of breed application solu- tions. The Parallels System Automation architecture allows for a relatively fast deployment and the ability to add virtually unlimited future services. Parallels System Automation can also provide a single panel interface for customers on any number of services, and across any number of levels of resellers. Parallels System Automation’s distributed architecture allows unlimited growth and the ability to deploy over many locations, enabling high-density single purpose servers to maximize server utilization. The single platform also enables transparent customer upgrade migrations and service additions. Lastly, Parallels System Automation has many administrative benefits that will increase application host- ing profitability. Parallels System Automation has built-in auto-provisioning and billing allowing labor and error free customer deployments. The Parallels System Automation single platform allows creating com- bination services with Microsoft and other OS services; Parallels System Automation requires the same skill sets to support both Microsoft and Linux applications, reducing the administrative required skill sets and training. Additionally, built into Parallels System Automation is a monitoring capability that will assess system performance and health to proactively manage resources, reducing administrative tasks and providing a better level of service to end customers. BenefITs for end CusTomers Customers are increasingly considering outsourcing Microsoft applications. The primary benefit for IT or- ganizations is cost and management reduction. Outsourcing enables lower maintenance and administra- tion costs by alleviating patch administration and limiting required administrative support skills. Without complex, time-consuming application coverage, IT departments can focus on other areas of support. Outsourcing also helps to eliminate capacity planning and enables a full utility computing model. Organi- zations only pay for IT resources consumed. Also, application outsourcing enables access to application expertise and infrastructure. Applications change quickly and interact with many other technologies. One example is the risk of a security breach. Leveraging centralized expertise ensures that organizations have fewer exposures due to lack of applica- tion expertise. Access to application expertise will also allow organizations to quickly deploy advanced capabilities such as mobile support. One of the biggest benefits a customer has from application outsourcing is that providers are able to invest in technologies such as Parallels System Automation that enable service delivery enhancements © Parallels Powerful Application Hosting 12
  13. 13. such as automatic service activation for new hires, further enhancing the efficiency of IT administrative teams. Parallels System Automation’s control panel for customers and the application administrator are huge benefits, allowing a completely custom interface and self-management capabilities. WHo BenefITs THe mosT? • Companies that can’t afford significant upfront costs of new infrastructure deployment • Companies that don’t have the IT expertise or resources to deploy these applications • Companies with multiple small offices and/or highly mobile workforce • Companies running older Exchange versions but fear that upgrades will be painful • Companies that are suffering from viruses and spam • Companies with no dedicated IT resources Conclusion Application hosting is an important growth area in the hosting market. Service providers can attract new customers and increase the average revenue per customer by hosting advanced applications. In addi- tion, application providers can differentiate themselves and increase service margins by offering unique application bundles. Successful application hosting requires an infrastructure that is flexible, modular, and distributed. Flex- ibility is required in order to offer the latest applications without having to re-architect the hosting infra- structure. Modularity is important to support new types of service loads and servers without impacting existing services. Having a distributed architecture is important to allow for rapid growth for popular applications and to provide a way to scale back on applications which are not as well received in the marketplace. The Parallels System Automation solution from Parallels provides an infrastructure which is flexible, modular, and distributed. Parallels has the most experience of any company when it comes to building and managing hosted services. This fact is proven by the large number of Parallels customers as well as by the number of managed servers running Parallels software. Windows hosting is the fastest growing segment of the application hosting market. Parallels has re- sponded to this growth by forming a partnership with Microsoft and building the only solution that pro- vides the entire range of Microsoft Windows application management capabilities in a flexible and robust architecture that is capable of meeting carrier-level solution requirements.
