CLOUD-BASED EMAIL: A GROWING MARKET

Email and collaboration services remain among the core applications that IT departments universally provide to their users, and these services are increasingly moving to cloud-based solutions. Gartner, a leading IT research and advisory company, forecasts worldwide total email and calendaring software revenue at $4.4 billion in 2012, growing to $6.1 billion in 2015. Cloud-based email and calendaring services will represent 15% of the market by 2015,1 with compound average growth rates of 38% from 2010 to 2015.

Why is collaboration moving to the cloud? In today’s challenging economic environment, companies are looking for ways to reduce costs and do more with fewer IT resources. In fact, the typical company spends as much as 80% of its IT budget to simply maintain the status quo (“keeping the lights on”), leaving the business starved for new and updated capabilities that can improve business processes and increase overall competitiveness. Business opportunity is literally trapped within IT infrastructure.

For businesses with limited budgets relying on a legacy application, email can be a burden and a significant source of lost productivity due to poor Web interfaces and significant downtime. Forrester Research, Inc., a leading independent research firm, reports that organizations moving to the cloud have these objectives in mind: trimming upfront and ongoing email costs; freeing up resources for strategic initia-tives and increasing flexibility; and providing quicker and easier access to new features and services.2 Moving to the cloud addresses many of the challenges of legacy on-premises email applications, such as Microsoft Exchange 2000/2003, IBM Domino 6/7/8 and Novell Groupwise.

CHALLENGES OF LEGACY EMAIL APPLICATIONS

Lost ProductivityThe end user experience on legacy email solutions is painful and anti-productive, from poor Web interfaces, limited mobile options, and storage quotas to ap-plication downtime and dependencies on local .PST files. Because email and collaboration is the application they use most frequently, business users demand productivity from the solution. Users want access anytime, on any device, on any platform and anywhere — even while offline. But legacy platforms, including Microsoft Exchange, lack a consistent experience across different browsers and offline clients, impose restrictive Inbox storage limits, and suffer from frequent downtime. Gartner predicts that by 2016, at least 50% of enterprise email users will rely primarily on a browser, tablet or mobile client for their email, instead of on a desktop client.3 Providing users with both access and a consistent email experience on their mobile devices has become a necessity to meet user needs and maintain their productivity.

Insufficient StorageToday’s end users have become accustomed to free consumer email services that offer multi-gigabyte mailbox storage limits. Just as bandwidth demands have increased with the growing exchange of large file formats, videos and other rich media, the strain on corporate email storage limits has increased, as well. Employ-ees lose productivity as their ability to send messages is halted the moment the Inbox exceeds the enforced storage limit. And IT resources are wasted trying to manage inefficient storage resources.

Compounding this email management burden are various limitations of the storage architecture underlying Microsoft Exchange, the most common legacy platform. IT administrators must purchase additional costly storage capacity or increase storage performance in order to mitigate insufficient storage quotas. Furthermore, managing storage servers and performing related archiving, backup and disaster recovery related tasks can consume up to half of IT support costs. Legacy systems also require significant resources to scale as the business grows, and often cause recurring server downtime, further impacting IT management challenges.

Proprietary PlatformsEnd users are stymied by the proliferation of separate applications. This problem isn’t just limited to applications such as Salesforce, Oracle and SAP, but extends to social and Web applications like Facebook, Google and Dropbox. Today’s em-ployees are demanding a hub of communications that aggregates and integrates multiple applications into the one they use most frequently — email. To achieve this, applications need to support openness; unfortunately, many legacy systems are practically impossible to extend to third-party applications, or customize to internal requirements. Outlook, for example, does not allow users to embed video into an email and is limited in functionality for the integration of global work-groups and unified communications systems. In contrast, open source platforms protect the service provider’s investment with simpler management and more cost-effective scalability. Open solutions offer standard protocols for interoper-ability and easy integration to enable development of value-added services, dif-ferentiated features and seamless support for all clients and operating systems.



3

Costly and Burdensome ManagementLegacy email solutions like Microsoft Exchange are difficult to manage and prevent administrators from supporting user requirements of a variety of desktop clients, mobile devices and operating systems. Frequent updates must be deployed on all Outlook clients and, in many cases, the entire system must be brought down in order to implement an upgrade.

The proprietary architecture of Microsoft Exchange locks customers into a Windows-based platform, which requires redundant hardware and software, and dedicated IT resources to monitor and resolve issues. Ensuring high availability on such closed platforms requires expensive technology to replicate Exchange and prevents the use of open-source or lower cost alternatives. Small and medium businesses with limited IT budgets are often unable to offer optimum service levels due to the infrastructure and resource costs required to do so in house.

IT as a ServiceAll of these challenges are motivating businesses to seek more flexible, lower cost alternative solutions for email and collaboration. To break the trend of ever-decreasing flexibility, combined with ever-increasing costs, a new model is emerging — IT as a Service. This approach extrapolates applications and informa-tion from the complexity of underlying infrastructure, so IT can focus on enabling business value through collaboration. Businesses of all sizes are migrating to IT as a Service for a more business-centric approach to IT that enables operational effi-ciency, competitiveness and rapid response. IT shifts from producing IT services to optimizing production and consumption of those services in ways consistent with business requirements. Service providers, such as CSC, can help businesses make this shift to IT as a Service and change the role of their IT department from a cost center to a center of strategic value.

Research suggests that businesses are making the shift to IT as a Service initially with hosted email solutions. Email is the number one application organizations are moving to the cloud. Not surprisingly, reducing IT costs is the primary driver for this transition. In addition to cost savings, the IT as a Service approach has also dramatically shifted expectations for end users and IT operations. These expectations are driving business requirements for how email and collaboration solutions will be delivered.

CLOUD COLLABORATION APPLICATION TRENDS

Consumer Expectations Driving Business RequirementsToday, employees want to use data and applications at work in the manner they are accustomed to in their personal lives. Users want applications to be available on any device, anywhere and anytime. These applications need to be available using traditional desktop clients, as well as a variety of browsers and mobile devices to optimize employee productivity.

The collaboration cloud is a hub for communications: regardless of device, the user has the context needed to make decisions — e.g., what flights to take, which pur-chase orders to accept/reject, or what information should be synced with the CRM system. Additionally, users want to be able to share information with co-workers, partners and other external users in order to solve business problems. In order to maximize productivity, employees need to be able to collaborate seamlessly with integrated applications that can be easily accessed regardless of location or device.

In a recent study with more than 3,500 cloud computing users, one of the key findings was that for 33% of respondents, the number one reason they adopted cloud was their need to better connect employees who use a multitude of computing devices.4

Application ManagementIn order to empower employees with this agile collaboration experience, organi-zations need a service that facilitates easy management, rapid deployment and migration. Organizations need an IT as a Service approach that offers built-in security and reliability, to reduce the need for additional IT resources. Cloud pro-viders must make it simple for administrators to manage service levels, perform remote device wipes of data and easily install software and security updates. Providers must also remove the management headaches of storage limits by leveraging economies of scale to offer low-cost storage. IT administrators need to be able to easily perform archiving, backup and disaster recovery processes without the drain on IT resources and cost of legacy systems.

Best-in class solutions are based on open platforms that offer simple integration with ERP systems, global address contacts, travel information and other applica-tions, delivering the right content in the right context for extreme end user pro-ductivity. Only solutions that are platform agnostic can offer such broad-based support and integration with third-party applications.

Data Center FlexibilityAnother key change in the IT market is that organizations want the flexibility to deploy applications in a private or public cloud. In order to maximize flexibility and drive down the total cost of ownership (TCO), applications need to be portable and provide support for standards-based virtualization and cross-plat-form back-up tools, easing the IT management burden. And this evolution to the cloud has not changed the core IT requirements of high availability and security. The efficiency of cloud computing can offer businesses higher service levels than the business could afford in house, due to budget and resource limitations.

SELECTING THE RIGHT SOLUTION

If you are considering moving your email and collaboration to the cloud, there are several key criteria to consider when choosing which solution is right for your organization.

Complete SolutionBest-of-breed solutions offer a comprehensive collaboration suite that includes unified communications, social media integration, support for a variety of mobile devices and other value-added services that are aligned with business functions. Best-in-class solution providers offer services to help you migrate from your current platform and manage a fully integrated suite of collaboration services.

Leading SaaS providers such as salesforce.com and WebEx have set end user expectations for a rich user interface. You do not want to compromise on fea-tures when transitioning from on-premises to Web-based solutions. A baseline requirement is the ability to access email both online and offline and on any mobile device. Be sure the vendor you select can offer support for a variety of mobile devices.

Another question to consider when defining your complete solution is: How extensible is the messaging platform? Is it based on open standards that will facilitate integration with your most important applications? Integration with third-party or custom enterprise applications will greatly enhance end user productivity, allowing end users to access other applications without leaving the messaging interface, and eliminating additional steps required to copy and share information easily across applications.

What level of management support do you require? Is security a concern when migrating your applications to the cloud? Do you need to retain some or all of your users and email application behind your firewall? Do you need to support multiple domains? To address these concerns, you need to understand the level of management support that is included with the service and the availability and response time SLAs that will be delivered. To address security issues, you want to ensure that the cloud infrastructure provides the physical, logical and access control security standards you require. And if you are using a leveraged resource model, you need to ensure that a dedicated virtual application is provided for each client. If all or some of your user accounts must be retained behind your firewall due to security policies or compliance requirements, then deployment options offered by the supplier become extremely important. If your enterprise requires multiple domains, you will save on operating costs if the solution provides this capability.



6

High Performance at the Lowest TCOBe sure the supplier you select for your email and collaboration solution builds on a modern, distributed architecture — designed for high scalability that ena-bles you to support hundreds of thousands of provisioned users per dual CPU server for the lowest TCO. Best-of-breed applications offer native volume and hierarchical storage management (HSM) to accommodate large quotas on com-modity storage and can provide multiple mail domains to support changing busi-ness needs. Finally, to satisfy business security requirements, the solution you choose should include strong, Internet-based security (SSL/TLS for all protocols), with support for single sign-on.

DEVELOPING YOUR BUSINESS CASE

The shift to IT as a Service represents an exciting opportunity for IT organizations. But in order to capture the greatest benefits, the first step is to choose the right package and the right support level. A sample portfolio might include: Sample Email Packages

Features Bronze Silver Gold Platinum Email/Calendar/Contacts

Mobile Support

Shared Folders/Documents

Availability 99.9% 99.9% 99.9% 99.95

The next step is to outline your costs, including software, infrastructure and operating expenses. For software, consider your cost for email and collabora-tion application licensing and support, Linux licensing and support, virtualization software licensing, and additional licenses for add-on features such as antivirus and anti-spam gateway, archiving and disaster recovery. For infrastructure, consider your costs for servers, production storage (measure on a cost per GB including disk, controllers and connectivity), backup/snapshot storage, disaster recovery infrastructure and archiving server and storage resources. Finally, consider your operating expenses for administration, bandwidth and data center resource costs. Once you understand these costs, you will have a benchmark to compare alternative cloud solutions to your current on-premises application.
