G00237716 Top 10 Technology Trends, 2013: Cloud Computing and Hybrid IT Drive Future IT Models Published: 6 February 2013 Analyst(s): David W. Cearley, Donna Scott, Joe Skorupa, Thomas J. Bittman Cloud computing continues to evolve, with new technologies emerging to support the dynamic creation of cloud services. IT departments in large enterprises should play the role of IT as a service broker, and train staffs to manage cloud provider relationships. Impacts The need to deal with hybrid environments gives rise to hybrid IT process models and the positioning of IT as a service broker (ITaaSB). As the use of multiple cloud services increases, enterprises should look to cloud service brokerages (CSBs) to facilitate consumption as part of an overall hybrid IT strategy. As cloud computing matures, IT departments will need to establish a more strategic approach to IT operations and service management. Dynamic infrastructure requirements make software-defined networking (SDN) a critical component of private cloud development and external service consumption. Recommendations IT departments in large enterprises should become ITaaSBs for their organizations. Design private cloud services with a hybrid future in mind, and ensure that future integration and interoperability is possible. Evaluate third-party CSBs that can facilitate the consumption of cloud services. Train IT staff to enable them to manage cloud provider relationships and contracts. When there is sufficient value in the IT operations management (ITOM) functions embedded in the cloud management platform (CMP), replace superfluous ITOM tools. CMP vendors may represent potential lock-in, so select them carefully.

Insist that vendors support open, standard northbound controller APIs to maximize flexibility and minimize lock-in. Analysis Cloud computing is an important and disruptive long-term force in the industry, with a significant potential for impact on every aspect of IT, the business and how users access applications, information and business services. Cloud computing is shifting from an isolated project to a central IT strategy, and most organizations now assume that cloud computing, in some form, will become a reality. Cloud computing and related technologies continue to evolve rapidly, and there is continuing confusion and misunderstanding as vendors' cloud offerings proliferate and they hype "cloud" as a marketing term. Nevertheless, the cloud offers significant potential advantages in delivering greater business and IT agility, more rapid access to application enhancements, innovative new cloudoptimized applications, and a shift to operational costs and lower costs in some instances. Gartner estimates that total spending on cloud services will increase from $110 billion in 2012 to $210 billion in 2016 (see "Forecast: Public Cloud Services, Worldwide, 2010-2016, 4Q12 Update"). Gartner sees enterprise cloud strategies evolving in five key areas: Consuming cloud services Building private cloud services Securing, managing and governing hybrid IT and cloud Cloud-enabled and optimized applications Enterprise delivery of cloud services The primary focus during the past few years has been on building private cloud services and establishing models to determine if, when and where to consume cloud services. These continue to form the baseline for any successful cloud strategy. Companies that have not already established formal mechanisms to evaluate cloud services based on business benefits and workload/data constraints must do so in 2013 or risk falling behind. Likewise, companies that have not examined how they can apply targeted technologies and techniques from the world of cloud computing to build a cloud-like data center risk falling behind. In 2013, technologies such as SDN and CMPs are influencing the design of private cloud computing, and will lead to advances in consuming external cloud services. The need to establish hybrid IT strategies that span traditional and new cloud models becomes an imperative in 2013, and hybrid models, in one form or another, will influence cloud strategies for the foreseeable future.

Source: Gartner (February 2013) Impacts and Recommendations The need to deal with hybrid environments gives rise to hybrid IT process models and the positioning of ITaaSB Most enterprises that consume cloud services will operate in a hybrid model in which they must secure, manage and govern what is in their environments, as well as external cloud services including those that have been acquired without IT involvement. Enterprises must deal with application development, delivery and integration patterns that need to be modified to safely exploit this hybrid internal/external, cloud/noncloud environment. Meanwhile, users continue to clamor for the speed, agility, flexibility, more choices and the perceived cost savings that cloud computing promises. Hybrid IT is emerging as an approach to deal with these complexities; however, hybrid IT does not refer to a particular technological approach or delivery model. Hybrid IT describes a new mission and operational model for IT in a dynamically multisourced, heterogeneous world. In hybrid Gartner, Inc. G00237716 Page 3 of 8
IT, the role of the IT organization is to be the value-added enabler for the most effective and efficient use of services across the enterprise. Hybrid IT requires that the relationship between the IT department and the business evolve and expand. IT becomes the trusted broker for most, if not all, IT-based services, regardless of provider sourcing or the style of service delivery. In this ITaaSB model, IT takes responsibility for service delivery and service levels, even when those services are delivered by other providers. This eliminates the requirement for the enterprise user to be concerned about how a service is being implemented and acquired enabling them to focus strictly on using the service. As a broker, IT engages with the business to select services, while shielding them from many provider selection, style of computing choice and integration issues. It also ensures compliance with corporate and industry governance requirements. Recommendations: IT departments in larger enterprises should plan on playing the role of ITaaSB for their enterprises. Design private cloud services with a hybrid future in mind, and ensure that future integration and interoperability are possible. Determine the relative role of the IT organization and external brokers and integrators in fulfilling the hybrid IT mission. Establish security, management and governance models to coordinate the use of cloud services across isolation and provider boundaries, particularly across internal and external boundaries. As the use of multiple cloud services increases, enterprises should look to CSBs to facilitate consumption as part of an overall hybrid IT strategy As cloud computing adoption proliferates, so does the need for consumption assistance. CSB refers to the market model and roles that support the intermediation between cloud services and cloud consumers. A CSB (see "A CIO Primer on Cloud Services Brokerage") primarily delivers three capabilities: Aggregation Integration Customization These capabilities can be delivered by both internal and external service providers to add value to one or more cloud services (generally public or hybrid, but possibly private) on behalf of one or more consumers of those services. As part of the move to ITaaSB, IT departments should explore how they can position themselves as internal CSBs by establishing a purchasing process that accommodates cloud adoption and encourages business units to come to the IT organization for advice and support. This key element Page 4 of 8 Gartner, Inc. G00237716
of a hybrid IT model will enable IT to track the services that business users are acquiring and bring a degree of governance to the process. However, IT must walk a fine line. If this process is used simply to erect a barrier to accessing cloud services, individuals will once again bypass IT. The enterprise CSB approach can be implemented by modifying existing processes and tools, such as internal portals and service catalogs. In addition, vendors of operations management and portal software, as well as external CSB providers, will offer tools to facilitate the process. Augmenting ITaaSB will be external CSBs. During the next three years, we expect the use of external cloud brokerage to accelerate, with an expanded set of providers and offerings. Deploying cloud services will involve substantial integration work, and many CSBs will deliver integration services and employ business process management suites to address this complexity. Steady investments by IT distributors and communication service providers for cloud aggregation brokerage offerings will help small or midsize businesses acquire, leverage and maximize investments involving multiple cloud services. Recommendations: Focus on the cloud and internal CSB as key elements of a larger hybrid IT approach. Establish an ITaaSB model to facilitate the use of external CSBs, as well as individual cloud services. Train IT staff in relationship management to better enable them to manage cloud provider relationships and contracts. Determine the strategic focus of a CSB provider and align this with your greatest need aggregation, integration or customization. Evaluate third-party CSBs that can facilitate the consumption of cloud services. As cloud computing matures, IT departments must establish a more strategic approach to IT operations and service management The need to deliver CSB capabilities and establish ITaaSB is changing how IT delivers and manages services. Both operational processes and supporting tools and technologies must be re-assessed with an eye toward standardization, repeatability and automation to drive speed, reduce service delivery cost and increase quality. As a result, IT organizations are adding or modifying roles (financial managers, service delivery and automation specialists) and investing in IT operations and service management architectures in a more cohesive and integrated fashion. On the process side, IT organizations are shoring up their business management expertise in areas such as cost accounting, overall financial management, benchmarking and end-to-end process design. These efforts, along with other decision frameworks, are used to assess the relative merits of internal versus external services delivery and rationalize cloud sourcing strategies. These changes require IT to increase attention to the business of running IT like an external service provider, because they are selling and delivering IT services to the business. As a result, IT service and operations management has never been more strategic to organizations serious about cloud computing. Gartner, Inc. G00237716 Page 5 of 8
As the service and operations management architecture is redesigned, it will require a greater degree of integration of management tools. CMPs are emerging and evolving as the next generation core of the IT service and ITOM framework, one that enables management and governance over internally and externally delivered services, automated service delivery and business/financial management. Initial implementations often focus on provisioning frequently requested sets of services with variable demand on top of IaaS, so that both labor and infrastructure costs are reduced by raising utilization rates (e.g., development and test cloud). Longer term, cloud infrastructure services will be designed such that even single-instance services will be provisioned and managed from the CMP, making it more of a runtime service assurance platform. Moreover, CMPs will evolve to provide more-robust management of platform and application services. They will also need to make choices between management platforms that handle all services based on a heterogeneous infrastructure versus those that focus on optimizing a particular application or software infrastructure platform. Recommendations: When there is sufficient value in the ITOM functions embedded in the CMP, replace superfluous ITOM tools in your architecture. CMP vendors may represent potential lock-in, so choose them carefully. Mitigate CMP acquisition risks in this rapidly evolving market by developing a long-term plan and planning for technology migration. Recognize that using multiple CMPs creates silos that must be independently managed, and consider designating a top-level CMP for visibility across all cloud services. Dynamic infrastructure requirements make SDN a critical component of private cloud development and external service consumption A key component of any cloud computing strategy is making IT more agile and, therefore, more responsive to the needs of the business. Historically, it could take two months to provision physical servers and two weeks to provision the network. With the adoption of server virtualization, server provisioning is measured in hours. This makes the two weeks needed to provision the network a key bottleneck and a barrier to business agility. SDN is a new approach to designing, building and operating networks that support business agility. SDN brings the same degree of agility to networks that abstraction/virtualization has brought to servers. In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications. As a result, programmability enables automation, which supports highly scalable, flexible networks that readily adapt to changing business needs. SDN is increasingly being used as an enabler of cloud service implementations to support the need for rapid, dynamic and elastic scalability of the networking component of the cloud service.

Coordinate server, network and storage teams to maximize the benefits of a policy-driven, software-controlled data center. Insist that vendors support open, standard northbound controller APIs to maximize flexibility and minimize lock-in. Avoid getting hung up on architectural purity at the expense of a practical focus on agility and lower total cost of operation. Consider a multiphase approach that leverages network infrastructures, where appropriate, and enables longer-term capital expenditure savings by leveraging open-switch control protocols, such as OpenFlow.
