    [ The Challenges Behind Multi-Cloud Management ]

    INTRODUCTIONWith cloud services firmly established in the enterprise, businesses are in-creasingly turning to multiple cloud providers and a variety of deployment models to meet their unique application and workload requirements.

    A multi-cloud strategy offers increased flexibility and agility; however, at the same time, it makes connecting and managing a holistic IT environment significantly more complex.

    This white paper examines the emerging trend of multi-cloud and explains how companies can benefit from comprehensive tools for multi-cloud management that enable them to spend less time managing IT resources and more time on critical business activities.

    WHY MULTI-CLOUD ADOPTION IS GROWINGQuite simply, cloud services are on their way to becoming the dominant paradigm for business services. According to IDCs Cloud Futurescape 2015, more than 65 percent of enterprise IT organizations will commit to hybrid cloud technologies before 2016. By 2017, IDC said, 35 percent of new applica-tions will use cloud-enabled continuous delivery in order to achieve faster rollout of new features and increase business innovation. 1

    We use the term multi-cloud to refer to any IT architecture that merges at least two cloud-based services into one platform, as well as those that mix third-party clouds, private clouds and hosted infra-structure together.

    In practice, most enterprises will make use of substantially more than two cloud platforms. An indi-vidual company may mix services from one or two infrastructure-as-a-service providers for its storage and backup needs; use a platform-as-a-service provider for a variety of on-demand business applica-tions; and incorporate cloud-based security applications all while still making use of hosted or owned infrastructure for some data or mission-critical services.

    While the initial impetus for the move to the cloud came from the desire to reduce costs and increase efficiency in provisioning, there are four major reasons for the explosive growth in the use of a multi-cloud strategy:

    1. Complexity of modern enterprises: Modern businesses typically use dozens of internal, partner-facing and consumer-facing applications, and it is unlikely that a single cloud can provide everything a company needs to operate effectively.

    2. Competitive demands: Cloud services provide agility at a lower cost than on-premise solu-tions. More importantly, business intelligence has become a key competitive tool among companies, and cloud-based analytics applications can help deliver new insights in the growing amount of data they generate and store in multiple repositories. According to KPMG, 35 percent of enterprises say business analytics is a prime driver of cloud services, and 73 percent achieve improved business performance. 2

    3. Increased usage of mobile: Public websites and online services now receive a majority of visits from mobile devices. According to IDC, by 2017, all of the line-of-business apps in customer-facing roles and 75 percent of internal applications will be built for mobile-first consumption.3 Cloud architectures better support access from anywhere via any device.

    4. Consumerization of IT: Cloud-based services, especially webmail and online storage, have won the loyalty of consumers with an unbeatable value proposition: easy to set up and use, and always available. As employees, they have come to expect the same and, in many cases, simply self-provision public cloud services at the office. According to the Cloud Security Alli-ance, 72 percent of companies globally do not know the scope of this shadow IT, which includes cloud apps adopted by individual employees, teams, and business units.4

    THE BENEFITS OF IMPLEMENTING A MULTI-CLOUD STRATEGY The 800 technology leaders who participated in KPMGs Cloud Survey ranked the cloud as the tech-nology that will have the greatest impact on driving business transformation. Businesses competing in the digital economy will find many benefits in a multi-cloud architecture. These key benefits include:

    Lower cost: Just-in-time provisioning of capacity without the need to purchase hardware can reduce capital expenses and operating costs.

    Flexibility: Multi-cloud architectures can help companies avoid vendor lock-in and, instead, choose the ideal location for data based on price, availability and performance.

    Choice: Companies can run applications and workloads on the most suitable environment based on application requirements, whether that means dedicated resources, a private cloud or a public cloud.

    Focus on higher-value business processes: Outsourcing provisioning and management of data storage frees IT and lines of business to focus on more core business needs.

    Use best-of-breed: Theres increasing specialization in cloud services in order to best serve specific needs of business sectors or technologies, such as healthcare-specific clouds or Hadoop-as-a-service. Specialized clouds can also reduce the number of cloud applications an enterprise needs to deploy, and/or provide a more tailored service.

    CHALLENGES OF A MULTI-CLOUD STRATEGYWhile there are compelling opportunities for increased business value and lowered infrastructure costs with multi-cloud services, these advantages come with a new set of challenges that businesses must meet.

    The first challenge is network complexity. A diverse array of in-house and cloud services typically comprises a multi-cloud architecture. Joining them via a public internet connection can create band-width problems that slow down applications. In this architecture, a mix of private and public data typically travels on different layers among the networked cloud services, which requires higher levels of management. There is also the risk of potential lack of integration among cloud services. Standard-ization of APIs has greatly improved the ability of cloud applications to exchange data. Nevertheless, it may be necessary for a company to create their own custom APIs in order to implement its preferred multi-cloud architecture both a costly and resource-intensive endeavor. Another challenge of a multi-cloud strategy is a lack of visibility into performance. While many cloud service providers offer management tools for their own offerings, it can be difficult for a company to keep track of how their overall infrastructure is performing without having to use multiple proprietary systems and tools. Mutual dependencies or interoperability issues could break the multi-cloud system even though each of its parts was operating correctly.

    Shadow IT is another major concern. According to the Cloud Security Alliance, only 8 percent of companies knew the scope of shadow IT within their enterprises. When establishing or expanding into multi-cloud, a company may have difficulty migrating data from rogue applications used by lines of business into the systems of preferred vendors. They may not even be able to identify the applications being used across the company.

    Multi-cloud also introduces new security and governance requirements. Because of the complexity and geographical distribution of its multi-cloud architecture, a business may need to develop federated systems for providing security and compliance with regulations, especially in sectors such as finance and healthcare.

    Finally, multi-cloud strategy typically drives the need for new IT skillsets. From CIOs down to tech support, IT staff will need to expand their skills, adding programming languages like Ruby on Rails and Hadoop. In addition, companies may need to hire personnel able to manage and monitor networked cloud services.

    TOOLS TO HELP BUSINESSES COMPETE IN A MULTI-CLOUD WORLDWith the growth in multi-cloud architectures comes a need for enterprises to be able to manage multiple environments holistically, in one consolidated view. As this market expands, vendors continue to provide more tools to help businesses overcome the challenges of multi-cloud management. The offerings include wider choice in basic cloud-management software, as well as new tools that provide better visibility. These tools typically come in a few different categories:

    Cloud data migration: As a company moves data to the cloud o
