  • 3. EXECUTIVE SUMMARY By any measure, the hype around Cloud computing has reached nearly deafening levels. However, behind the wall of hype lies a fundamentally straightforward concept — one that’s been percolating for many years in the IT world. Cloud computing is an architecture that enables IT organizations to parcel out portions of a shared pool of hardware and so ware resources to users through an automated, self-service request system. This model for IT, internally managed and externally hosted, offers tremendous benefits in the areas of cost-savings, IT responsiveness, and improved flexibility. However, its successful implementation typically requires organizations to overcome some significant organizational and technological hurdles. BMC So ware delivers solutions and expertise to clear these barriers, from the planning stages to the optimization and governance of a working Cloud. The payoff, in the end, is a transformed infrastructure that is flexible, highly responsive to business needs, cost effective, and unified. DREAMING OF CLOUDS: THE SKY HIGH GOAL Cloud computing is driving a great deal of IT investment. IT groups are seeking to give greater access to resources to their stakeholders, respond with agility to the needs and demands of the business, and at the same time, curtail costs. Clouds come in a variety of flavors, including: » So ware-as-a-Service (SaaS): Targeted at end users seeking to purchase applications, SaaS hosts those applications for the user and charges a subscription fee. » Platform-as-a-Service (PaaS): Designed for developers, PaaS hosts all the building blocks of a development environment, speeding up the development process and encouraging support for a platform. » Infrastructure-as-a-Service (IaaS): Comprised of the foundations of any IT environment, IaaS is the most fundamental type of Cloud, delivering operating systems and application stacks to internal or external customers. Fundamentally, a few core elements are required of an IaaS Cloud: » A self-service portal, enabling users to request and receive configured resources rapidly » An automated provisioning model, facilitating the creation of flexible, multi-tiered VMs to meet the specific needs of the user » A service-model, extending the traditional model of Business Service Management to the Cloud, and bringing with it the best practices that ensure service quality » A dynamic management environment that can actively monitor and respond to this ever-changing set of workloads in a way that optimizes service quality and cost This definition applies equally to private Clouds and public Clouds. Public Clouds are designed to sell capacity to companies with limited internal resources. Private Clouds mimic the same structure, but exist within the company’s datacenters, delivering flexibility and some cost-savings without leaving the walls of the organization. Hybrid Clouds are an amalgam of both, in which companies reach out to public Clouds to extend their own infrastructures, but manage them seamlessly. Finally, the concept of a community Cloud has been developed to describe coalitions of organizations, typically governmental or of the same type, who build a shared, secure external Cloud together. The ultimate goals of all these environments are: » More efficient use of resources, whether financial, physical, or human » Improved agility and flexibility, removing the IT barrier from business efficiency » Expanded service orientation, aligning IT and business goals more directly “ Enterprises investing in private Clouds and/or using the public Cloud for overdra or to build virtual private Clouds must invest in management technology to manage service quality and availability.

  • 4. A LADDER TO THE CLOUD: CHALLENGES GETTING THERE SUMMARY OF CASE STUDY While the concept of Cloud computing is reasonably straightforward, the execution does Concur Technologies embraced BSM come with its challenges. Each component must work hand-in-glove with the rest to enable for Cloud Computing, and in one year: a dynamic, stable, cost-effective, and flexible environment. Without careful attention, the » Increased server virtualization from equilibrium of a Cloud could easily be threatened. 5 percent to 42 percent virtualized Organizations face several challenges that must be addressed: » Reduced server configuration mistakes by 85-95 percent » First and foremost, Clouds must provide users with the ability to self-provision resources. » Has already saved $1.7 million Whether in internal private Clouds or third-party public Clouds, users must have a mechanism for selecting their preferences from a set of options and for initiating a According to Craig Baughn, vice workflow to generate this resource. In a process similar to that of ordering a laptop president of Concur’s hosting online, there are typically a variety of baseline options, capacity requirements, so ware services, the BMC solution “enabled options, and additional features — all of which represent a tailored, if not custom, us to re-allocate resources to other result. Identifying the options, creating the portal, defining the baseline requirements areas of the business because of the efficiency offered.” and approvals, and finally, provisioning the resources presents a complex orchestration challenge far beyond “copy and paste.” Specifically, organizations usually desire that (source: www.cio.com/article/506114/Inside_ One_Firm_s_Private_Cloud_Journey) the available service offerings be driven by user roles and constrained by security, organizational, or financial policies. » Second is the dynamic management challenge. Once commissioned, Cloud resources have tremendous flexibility to grow, shrink, move, change configurations, and ultimately, be decommissioned. This process mirrors that of a traditional physical datacenter, infused with a host of additional degrees of freedom (and thus, complexity). As such, it requires much of the same management best practices — augmented with Cloud awareness. Absent that, conditions will occur for which appropriate responses and controls are not well established, and the organization will experience increased costs, decreased availability, and reduced flexibility. In fact, organizations need to view Cloud as a catalyst for improving their IT maturity. » Third is the challenge of scope. Born of the virtualization world, Cloud computing is o en perceived as being uniformly based on x86 Microso Windows and Linux platforms; while, in fact, this is not at all reflective of the reality of the modern datacenter. Companies continue to be broadly multi-platform in their datacenters, running everything from blade servers to mainframes and leveraging a host of virtualization technologies, including hypervisors, Solaris™ zones and containers, and even LPARs. To limit the Cloud to a subset of the company’s systems is to hamper its strength and curtail its eventual growth. » Finally, a diverse group of public Clouds are being built by telecommunications firms and service providers the world over. Enterprises are increasingly seeking opportunities to leverage these external Clouds both for cost-savings and increased flexibility. However, the provisioning and management of those resources o en represent a separate IT challenge —one that, realistically, should be a seamless extension of the private Cloud, managed with consistent processes, policies, people, and tools. Thoughtful organizations, while embracing the benefits of public Cloud usage, are not willing to do so at the price of introducing new management silos. To implement and be successful developing a Cloud computing infrastructure, organizations should consider every stage of the environment — from planning and provisioning to operations and decommissioning. By adopting a layered approach, the fundamentals of management can be implemented, and then improved upon, generating increasing efficiencies and flexibility for the business. 2

KEY BENEFITS BSM FOR CLOUD COMPUTING CLOUD PLANNING BMC applies the proven principles of Business Service Management to the Cloud, in the » Discover and assess existing following ways: IT assets CLOUD PLANNING » Establish technical and business Cloud Planning lays the foundation of an efficient, effective Cloud environment by leveraging plans for Cloud transition a set of activities and solutions to ensure the private Cloud is tailored properly to meet the CLOUD LIFECYCLE needs of the organization. These steps include: MANAGEMENT » Efficiently and accurately » Developing and maintaining an accurate picture of the current IT environment — from provision Cloud services through existing VMs and physical machines to the dependencies between these systems. BMC a self-service portal driven by a Atrium Discovery and Dependency Mapping, working in conjunction with the BMC Atrium service catalog CMDB, can create a current, accurate base from which the requirements of the Cloud can be created. CLOUD OPERATIONS AND OPTIMIZATION » With a baseline understanding of the types of workloads that will be utilizing the » Proactively monitor the Cloud Cloud, BMC BladeLogic Server Automation Suite can come together with BMC Atrium by predicting and repairing Orchestrator and BMC Capacity Management to design the services that will be delivered performance issues before they via the Cloud. From the quantity of resources required to the desired service levels and impact users costs to the application stacks, these solutions help organizations balance the flexibility » Actively manage capacity to ensure desired by the business with the control required for successful operations. optimal use of resources » Once designed and built, the transition of existing workloads onto the Cloud requires a CLOUD GOVERNANCE combination of automation and organizational change. The same tools that helped create » Run IT like a business, with the Cloud can now assist in this move, ensuring continuity from the physical or virtual visibility and predictability of environments into the Cloud environment. Maintaining the context, data, configurations, financial metrics and histories on each workload is critical both to their ongoing operations and to measuring the success of the Cloud initiative. » View and manage asset usage for reduced costs BMC CLOUD LIFECYCLE MANAGEMENT SUMMARY OF CASE STUDY BMC Cloud Lifecycle Management ensures the full lifecycle of resources in the Cloud is (BMC I.T. ORGANIZATION) well structured and flexible. As the most visible manifestation of the Cloud computing infrastructure, the provisioning experience must be easy, flexible, and rapid, while still BMC’s own IT department utilized ensuring that the operational integrity of the environment is maintained. BSM for Cloud Computing and: » Reduced physical servers by 25 » A self-service portal is the only interaction most Cloud users will ever have with the percent, and achieved 70 percent infrastructure, and thus should be a positive experience. Rather than simply offering a CPU utilization limited, cookie-cutter set of VMs, cloned from static images, BMC BladeLogic Server Automation Suite, BMC BladeLogic Network Automation, and BMC Atrium Orchestrator » Reduced power consumption by work behind the scenes to provision and deploy custom services — from OS to 23 percent application stack to network configuration. Exposed through a robust service catalog, » Increased server admin this capability enables each Cloud resource to both conform to operational requirements productivity by 600 percent (such as policy or cost constraints), while still meeting users’ individual needs. » Reduced server provisioning time » Once Cloud resources are no longer needed, they should be properly decommissioned, from two weeks to five minutes or else the detritus of prior workloads will continue to consume resources and clog the The financial payback of this Cloud. BMC Cloud Lifecycle Management ensures that workloads with termination dates investment in Cloud, which was are appropriately handled, saving resources and greatly easing management. approximately $2 million, was achieved in fewer than six months. » Cloud resources are fundamentally service offerings, and thus should be measured and managed as such. With integration into the BMC Remedy IT Service Management Suite, BMC Cloud Lifecycle Management ensures that the Cloud is not managed in a vacuum, but rather alongside traditional resources, ensuring continuity of service throughout. 3

With proper, proactive performance management in place, IT can environmental integrity ensure that service quality is maintained. » A modular, complete solution that can be implemented in stages » Capacity management, like performance, is ever-changing in world of self-service and customized to meet the Cloud provisioning and automated decommissioning. As sophistication increases, managing the needs of your enterprise capacity of the environment and the resources available to each VM will become critical not only to their service levels but also to forecasting additional investment needs. BMC Capacity Management can monitor, analyze, and forecast capacity needs in this new, dynamic environment. CLOUD GOVERNANCE Cloud governance enables IT organizations to operate their Cloud environment like a business. Organizations need the ability not only to calculate the costs associated with delivering services, but also to optimize resource utilization in the environment and ensure that compliance requirements are consistently and efficiently met. By linking an understanding of service costing with Cloud service level definitions, utilization, capacity investment, and public Cloud pricing, decisions can all be driven by — and aligned to — the priorities of the business. The Cloud environment, private or hybrid, must create the flexibility to address the needs of the business, while at the same time, optimize its own operations to ensure costs and investments support business goals. » IT service costing marries detailed information about the workloads in the Cloud with costs associated with hardware, network, so ware, and other relevant resources. By combining BMC Service Cost Management data with service level metrics and BMC Capacity Management, a financial strategy for the growth of the Cloud can be created to support the technological direction. 4
