gigamon: monitor your virtual servers better
DESCRIPTION
Download the whitepaper from http://www.gigamon.com/virtualized-data-center Cloud computing and network virtualization provide undeniable cost and scalability benefits. However, the elastic and dynamic nature of cloud computing brings a whole new set of visibility challenges for IT professionals. Though response to immediate virtualized data center needs have improved, visibility to diagnose problems and analyze performance has become more complex. Take a look at this presentation to know how Gigamon gives you more visibility into your virtual network.TRANSCRIPT

Migration to Virtualized Servers and Cloud Computing Offers Many Benefits but also Many Challenges
Benefits Flexible, dynamic IT infrastructure Improved resource utilization Huge cost savings Better TCO and ROI
ChallengesReduced VisibilityGreater difficulty in finding & fixing performance problemsSecurity
RealityYour team is virtualized and going to the cloud, like it or notSo you need to figure out how to overcome the challenges

Why the Reduced Visibility?
Note that all of these contributors to reduced visibility are actual benefits of virtualizationThe issue is how to get the benefits while dealing with the challengesLet’s start with the challenges
Distributed application
architectures
VMs on the move
Traffic not traversing the
physical network

Challenge 1: Traffic not Traversing the Physical Network
The result: Only part of the traffic is visible to monitoring at the edge
With virtualization, a lot of traffic doesn’t traverse the physical network
Physical Switch
Traditional monitoring tools can’t see new encapsulated traffic in overlay networks

Challenge 2: Distributed Application Architectures
Once monolithic, large applications are now running in a distributed application architecture
The results: More east/west traffic handling applications More difficult to monitor and troubleshoot

Challenge 3: VMs on the Move
The result: Limited visibility and potential security gaps
VM migration across servers or across data center boundaries uses technologies such as VMotion, which hide traffic details from monitoring devicesYou need to track vMotion events in order to retain monitoring continuity and history

If you can’t see it, you can’t
control it
Virtualization creates silos of IT hidden from security tools
Additional Challenge: Security

Additional Challenge: Pressure on IT Infrastructure and Admin
Increased demand to monitor and report on all
network traffic
Need to stay in compliance with internal and external regulations
