Virtualization
All companies are rapidly virtualising servers 55% of firms will have implemented by 12/09* Additional 29% planning budget for virtualization
Major changes New connected elements (VMs) New network elements (vSwitches, vNICs) New topological constructs
Challenges for IT managers Loss of visibility into:
Topology changes Within a hypervisor and VM-to-VM
Loss of control Unclear responsibilities New and unclear boundaries

The Cloud
Gartner's 2010 CIO survey identified cloud computing as the No. 2 strategic technology investment for CIOs globally
Major challenges Loss of visibility with most processes taking place on another
network Proving points of delay/failure: internal network, ISP, or cloud
vendor
IT operations need visibility into cloud environments Monitor performance and availability Enable metering and billing Integrate with enterprise management systems

Unified Communications
UC combination of e-mail, messaging, telepresence, VoIP, video According to Cisco:
By 2013, video (TV, VoD, Internet video, and P2P) will exceed 90% of global consumer IP traffic
Video communications traffic increase 10x 2008 to 2013
Preparing for the video conferencing bandwidth hog Single telepresence suite requires 5 Mbps dedicated bandwidth Low end requires 5-10x bandwidth of typical VoIP calls Delay or outage is a major issue
Bottom line for network managers UC does not represent major change vs existing applications Video requires added planning, policy, quality monitoring and
troubleshooting Monitor and set the boundaries

Increased Application Responsibilities
Trends 80% of application failures blamed on network problems, but networks
will be less than 20% of the root cause* User experience and business services hinge on application
performance Web enabled applications
Challenges Increased layers and platforms to monitor Easier for customer to “walk out of your shop” Rate of change will be constant

Performance Management Requirements

Dropped packets = unresolved problems, especially in UC
Ensuring validation of new technologies requires Reliable 10 Gb capture Large volume of data storage Rapid search to locate root cause
“Same size needle, larger haystack”
Moving at Data Centre Speeds

Virtualized environments create black holes for ill prepared
Need visibility into VM-to-VM communication, even on same physical host Example: Multi-tiered applications
Cannot analyse with tools that cannot be virtualized
Ensure integrated visibility into physical and virtual environments
Virtualization

Tools used to manage cloud services are often similar to tools used to manage internal infrastructures
Verify ability to track and analyze conversations from user to end destination in the cloud
Need in-depth WAN/Internet performance monitoring metrics: SLA enforcement Tracking precedence Locating and proving source of the problem:
internal network, ISP, or cloud provider

Solutions need visibility to validate performance
UC-specific metrics Jitter, quality, precedence settings, etc…
View UC within context of overall network traffic
Separate Network and UC problems
Unified Communications

No brainer: It’s not the network, it’s the application
Need application-specific metrics and information
Integrate multiple monitoring perspectives Packets, NetFlow, SNMP, WMI, WAAS, NBAR
Automated expert analysis
Baselines and intelligent alarms
Complete packet capture for problem resolution
Increased Application Complexity
