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

Challenges

Reduced VisibilityGreater difficulty in finding & fixing performance problemsSecurity

Reality

Your 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 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

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 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

Increased demand to monitor and report on all

network traffic

Need to stay in compliance with internal and external regulations
