1 A Custom Technology Adoption Profile Commissioned By Juniper Networks April 2014 Hybrid Cloud Places New Demands On The Network Introduction Today s business pressures require IT resources to be a cost-effective mixture of public and private cloud resources. Consequently, IT infrastructure and operations (I&O) professionals need to rethink how they design, deploy, and manage IT services in a way that seamlessly combines internal resources and public cloud platforms into a single platform. Under the old static IT model, security, reliability, and scalability have been fundamental pieces to connecting business resources; however, as IT shifts to creating a hybrid cloud platform, questions arise as to what new demands will be placed on the network. To uncover what changes had to be made to the network and what IT decision-makers prioritize when evaluating cloud networks Juniper Networks commissioned Forrester Consulting in January 2014 to examine its industry data on cloud and to pair the findings with a custom study of IT decision-makers who have experience tying together public and private infrastructures.
2 1 Businesses Want IT Resources To Be Fast And Responsive Businesses want to leverage the best IT platform possible, which is ultimately a combination of internal and external resources. On the whole, cloud services provide businesses with irresistible benefits. Adopting infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), or software-as-aservice (SaaS) can reduce internal labor costs associated with the operation, maintenance, and upgrades; and it allows IT leaders to deploy these services much faster and with more agility. According to the Forrsights Developer Survey, Q1 2013, 34% of organizations see cloud environments as a way to optimize development, and 33% believe that it enables faster production and deployment (see Figure 1). Moreover, 31% have implemented cloud initiatives in order to cut the costs of on-premises environments.

3 2 As part of this study, IT decision-makers were surveyed on their plans to deploy a private cloud in addition to using IaaS/PaaS cloud services. Seventy-five percent of respondents said their organization is planning to deploy this hybrid environment at their organizations (see Figure 2). FIGURE 2 Three-Quarters Of Organizations Plan To Deploy A Hybrid Cloud Is your organization planning to deploy a private cloud in addition to using cloud (infrastructure/ platform-as-a-service like Rackspace, Amazon.com, etc.) services? multitenancy, resource pooling, and scale-out within each cloud domain, for instance. FIGURE 3 Three-Quarters Of Organizations Using Public Cloud Platforms Had To Make Changes To Their Networks In regards to planning on using the cloud services or your experience with cloud services, has your organization had to or will it change the network infrastructure for its private, public and/or hybrid cloud initiative?

While of organizations surveyed for this profile have not needed to overhaul their network infrastructure to accommodate a cloud platform, 73% have needed to make changes since not all the architecture is under their domain (see Figure 3). Consequently, I&O teams have to create an operations center that requires them to shift their mindset about controlling infrastructures and leave cloud infrastructure management to the cloud providers. Then enterprise I&O professionals can transition to being responsible for Base: 52 IT decision-makers in the US Source: A commissioned study conducted by Forrester Consulting on behalf of Juniper Networks, January 2014 I&O teams struggle to do this. Respondents who indicated that their organization encountered obstacles when incorporating cloud services were given a list of nine issues and asked to select their top three. Fifty percent selected the difficulty to integrate public cloud services (IaaS or PaaS) with private data center infrastructure as one of the top three reasons (see Figure 4). Nearly half of respondents (46%) cited lacking the capability to integrate with cloud portals, management and orchestration systems, or homegrown management systems, and about one-third believe that it is too timeconsuming to update the network when adding or changing applications, services, and data (). Twenty-nine percent also listed the lack of flexibility to support multitenancy networks at scale.

Difficult to integrate public services (infrastructure-as-a-service or platform-as-a-service) with private data center infrastructure to create a seamless infrastructure Lacking the capability to integrate with cloud portals, management and orchestration systems, or homegrown management systems Too time-consuming to make changes to the network when adding/changing applications, services, and data 46% 50% Not flexible enough to support multitenancy networks at scale The infrastructure can t cater to different types of hosted applications, by supporting tiered service levels in terms of ADC capabilities or cost models 25% Didn t or don t have the technical skills in-house Physical deployments and management of networking devices like switches/adcs/firewalls are too slow and hamper the of complete service creation The number of networking services/requirements (switching, load balancing, security, etc.) growing beyond the available resources to manage them Current network incompatible with the requirements of the cloud service None 7% Note: Don t know not shown Base: 30 IT decision-makers in the US Source: A commissioned study conducted by Forrester Consulting on behalf of Juniper Networks, January 2014 Survey respondents identified three fundamental hybrid cloud components that must be addressed: security, reliability, and scalability (bandwidth and performance). Half of respondents surveyed for this profile stated that network security when connecting to cloud services has the biggest impact on creating a hybrid cloud, followed by network bandwidth (42%), network performance (42%), and network reliability (39%) (see Figure 5). Once these fundamental features are implemented, the focus turns to network automation/programmability (32%) and network virtualization (32%), enabling seamless integration of features and ultimately a truly hybrid cloud. This means a lot of the same best practices that network engineers use today are just as critical if not more so to enabling hybrid clouds. Then once these network fundamentals are in place, automation can be added to make the network capable of dynamically adapting to the demands of the cloud.

Cloud users will then have easy and customized multi-tiered and multi-cloud applications with a few clicks: preconfigured image templates, application stack blueprints, and configurable inputs like domain, database, compliance, security, and load balancing parameters. This enables developers to deploy application or infrastructure services from the service catalog in minutes by removing any manual approval processes and replacing them with policy-driven workflow. To make these on-demand, elastic services possible, web services companies have focused on automating everything. These best practices have filtered into the enterprise space. Consequently, enterprise I&O teams have turned to automation software solutions. Sixty percent of organizations surveyed are turning to server administration solutions, followed by 54% implementing storage administration, and 46% adopting network administration (see Figure 6). This order of priority is logical, but it s important to note that if just one of these elements such as the network is not automated, it can be a hindrance to truly delivering elastic services. Automating all the data center components enables the platform to transition into a platform that has no boundaries. These tools can automatically discover the OS, network, and storage configurations of in-place multi-tiered applications, and then inject drivers, tools, and security components and package the app for deployment to a range of private and public cloud stacks.

Server administration 60% Storage administration 54% Network administration 46% General IT processes Private cloud delivery Incident management Release management Change management Problem management 40% 40% 39% 37% 36% 34% Converged infrastructure Service brokering 14% Base: 200 hardware decision-makers in the US Source: Forrsights Hardware Survey (Q3 2013) Forrester Research, Inc Conclusion I&O professionals using hybrid clouds need to evolve their strategy toward managing holistic services, not individual infrastructure components. IT organizations that have made the change don t manage discrete components but manage a system that interweaves the network elements to create a seamless hybrid cloud platform. Before this can be possible, I&O professionals start with ensuring they have secure, scalable, and resilient network infrastructure. Surprisingly, a vast majority of respondents didn t feel that their existing network had the capabilities to meet these demands and had to upgrade in one or more of these areas. Then the teams remove the manual elements and initiate automation capabilities to enable the network to quickly respond to the dynamic scale-up and scale-down of an elastic set of resources according to business demands. This automated cloud network infrastructure interweaves multiple network properties and components such as policies, controls, security and virtualization, local area devices, and acceleration technologies to seamlessly connect users to both public and private cloud resources. The results of this study show that IT decision-makers value the performance, reliability, and security of the network that underpins their cloud and that these network fundamentals together with automation are the top priorities to enable a successful hybrid cloud deployment.
