With mobility and cloud trends today, network infrastructure now encompasses everything from virtual machines (VMs) to employees’ personal devices brought in through “bring your own device” (BYOD). IT is expected to respond to this shift with 24×7 support, but in such a dynamic environment, it’s becoming difficult to determine whether applications or underlying infrastructure are performing as desired – let alone whether security, compliance, and audit requirements are being met.
A new white paper from Gigamon looks at how IT can better manage network complexity through software-defined networking (SDN) and traffic-based visibility. “Monitoring, Managing, and Securing SDN Deployments” examines how SDN deployments with traffic-based visibility solutions can help ensure end users are truly getting a good experience, applications are performing as expected, and adequate security measures are being put in place in the cloud.
SDN brings operational simplicity by having the Controller act as the central point of management and removing the need to manage every switch/router individually. But SDN also brings new challenges, as today’s management and security tools typically don’t have the visibility they need to accurately determine the security and performance of this evolving and changing environment. This white paper examines how increased traffic-based monitoring can help overcome those obstacles.
Gigamon looks at the main types of techniques for monitoring and managing networks today, and how SDN will affect the need for each. The white paper argues SDN likely will diminish the need for SNMP-style monitoring of individual devices while increasing the need for flow- and packet-based monitoring (i.e. traffic-based monitoring).
In fact, the paper says, traffic-based monitoring likely will become an integral component of SDN deployments because IT needs to monitor and manage both the SDN deployment itself, as well as the IT infrastructure that SDN will enable. Gigamon outlines how traffic-based monitoring solutions can help overcome challenges like controller and switch synchronization, network virtualization monitoring, and hybrid deployments. It also explains how enhanced traffic-based analysis can help pinpoint the source of security threats in highly mobile environments.
SDN can change the fundamental nature of networking to help it keep pace with changing demands on IT. Download the white paper to learn more about how combining SDN technology with increased traffic-based visibility provides an effective and reliable way to enable instrumentation for the SDN world.
