BUSINESS TRENDS
Virtualization is dependent
on the network, and the
network is incredibly
complex.
At least half of IT leaders said network complexity is
holding back virtualization for networks, storage,
applications and servers
SOFTWARE-DEFINED NETWORKING AND
VIRTUALIZATION
7
More than half the respondents will evaluate software-defined networks (SDN)
within the next two years to help automate and simplify network operations

SOFTWARE-DEFINED NETWORKING AND
VIRTUALIZATION
8
• Facilitates virtualized networks by abstracting lower-level functionality
• Decouples the control plane from the data plane
• Enables direct programmatic control of the network
• Management and operation of the network is handled and automated in a centralized
controller
• Provides network admins more granular control
• Network designers must consider entire infrastructure when creating workloads

• Nearly half of respondents have or expect to run into skill gaps when deploying SDN
• They also worry about lack of proven ROI
IT skill gaps
Unsure of ROI/ immature technology
Integrating with current technology
Staff resource constraints
Cultural barriers within IT

• Benefits of implementing SDN
– Increased network efficiency
– Improved IT services delivery
– Lower operating costs due to centralized network management
– Reduced capital expenditures
– Less dependence on proprietary hardware, dedicated appliances
and application-specific devices

VIRTUALIZATION AND SIMPLIFIED ARCHITECTURE
11
• Nearly 70% of organizations with more than 1,000 employees have plans to
simplify the IT structure to accelerate virtualization and cloud
• One in five are creating new IT teams to redesign the network

• Nearly all respondents
report that business
continuity and disaster
recovery (BC/DR) are
considered when
planning network
changes
• Network availability,
network security and
user connectivity are
top considerations

MANAGEMENT
17
• Optimal network management requires a single interface that provides visibility
into both the virtual and physical networks
• Helps organizations identify the source of performance and other issues
• Also provides a single interface to automate behavior across the entire network
SIMPLE, OPEN, SMART
18
• Many IT organizations have virtualized their data center resources
• But, to achieve even greater levels of agility and flexibility, they need to also
virtualize the network
• Juniper Networks MetaFabric™ architecture:
– Enables simple, open and smart data centers
– Accelerates the deployment and delivery of applications within
and across multiple sites and clouds
Simple SmartOpen
