Download the whitepaper from 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.

Migration to Virtualized Servers and Cloud Computing
Offers Many Benefits but also Many Challenges
2
Benefits
Flexible, dynamic IT infrastructure
Improved resource utilization
Huge cost savings
Better TCO and ROI
Challenges
Reduced Visibility
Greater difficulty in finding & fixing
performance problems
Security
Reality
Your team is virtualized and going to the
cloud, like it or not
So you need to figure out how to overcome
the challenges

Why the Reduced Visibility?
3
Note that all of these contributors to reduced visibility
are actual benefits of virtualization
The issue is how to get the benefits while dealing with
the challenges
Let’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
4
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
5
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
devices
You 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
8
Increased demand to
monitor and report on all
network traffic
Need to stay in
compliance with internal
and external regulations
