Pervasive Network Visibility
Enterprises are evolving – networks and applications continue to expand within IT organizations along with the volume and pace of information. The distinction between internal and external customers is blurring as everyone expects instant access to information with reliable and predictable network performance.
Despite budget restraints, IT organizations are expected to meet the demands for ever-higher bandwidth, lower latency, and superior user experience, as well as to drive efficiencies to improve communication, collaboration, and overall corporate productivity. As enterprises attempt to harness data to obtain high-quality, fine-grained relevant data for real-time insights, many are turning towards best-in-class tools to effectively manage, analyze, and secure their infrastructure. But there are challenges. As data is distributed across the enterprise, it puts an organizational strain upon the tools, and without critical traffic visibility, vulnerabilities can affect compliance, safety, or general IT best practices.
Visibility today means insight into infrastructure blind spots. Driven by the need for real-time decision making, network traffic provides network operations and security administrators with an authentic source of data to base these decisions. For pervasive visibility, the network traffic should be acquired from a variety of devices and applications—across physical, virtual and SDN/NFV environments—as well as private and public clouds. As infrastructure becomes more distributed, traffic volume and speeds increase, and the adoption of emerging technologies continues, the need to converge on a unified visibility infrastructure that not only simplifies and automates network traffic visibility, but also provides built-in intelligence, will drive the ongoing evolution of the Visibility Fabric. Given the complexity in today’s infrastructure, it is important that the fabric provides visibility into physical, virtual, remote sites as well as emerging SDN/NFV infrastructure as a single unified fabric with a common management and policy model, rather than as a set of disjoint nodes. Such a unified management model allows rapid visibility into infrastructure blind spots.
