Critical Challenges

5.
Virtualization <ul><li>All companies are rapidly virtualising servers </li></ul><ul><ul><li>55% of firms will have implemented by 12/09* </li></ul></ul><ul><ul><li>Additional 29% planning budget for virtualization </li></ul></ul><ul><li>Major changes </li></ul><ul><ul><li>New connected elements (VMs) </li></ul></ul><ul><ul><li>New network elements (vSwitches, vNICs) </li></ul></ul><ul><ul><li>New topological constructs </li></ul></ul><ul><li>Challenges for IT managers </li></ul><ul><ul><li>Loss of visibility into: </li></ul></ul><ul><ul><ul><li>Topology changes </li></ul></ul></ul><ul><ul><ul><li>Within a hypervisor and VM-to-VM </li></ul></ul></ul><ul><ul><li>Loss of control </li></ul></ul><ul><ul><ul><li>Unclear responsibilities </li></ul></ul></ul><ul><ul><ul><li>New and unclear boundaries </li></ul></ul></ul>Sources:: Forrester Research, EMA Inc

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

8.
Unified Communications <ul><li>UC combination of e-mail, messaging, telepresence, VoIP, video </li></ul><ul><li>According to Cisco: </li></ul><ul><ul><li>By 2013, video (TV, VoD, Internet video, and P2P) will exceed 90% of global consumer IP traffic </li></ul></ul><ul><ul><li>Video communications traffic increase 10x 2008 to 2013 </li></ul></ul><ul><li>Preparing for the video conferencing bandwidth hog </li></ul><ul><ul><li>Single telepresence suite requires 5 Mbps dedicated bandwidth </li></ul></ul><ul><ul><li>Low end requires 5-10x bandwidth of typical VoIP calls </li></ul></ul><ul><ul><li>Delay or outage is a major issue </li></ul></ul><ul><li>Bottom line for network managers </li></ul><ul><ul><li>UC does not represent major change vs existing applications </li></ul></ul><ul><ul><li>Video requires added planning, policy, quality monitoring and troubleshooting </li></ul></ul><ul><ul><li>Monitor and set the boundaries </li></ul></ul>

9.
Increased Application Responsibilities <ul><li>Trends </li></ul><ul><ul><li>80% of application failures blamed on network problems, but networks will be less than 20% of the root cause* </li></ul></ul><ul><ul><li>User experience and business services hinge on application performance </li></ul></ul><ul><ul><li>Web enabled applications </li></ul></ul><ul><li>Challenges </li></ul><ul><ul><li>Increased layers and platforms to monitor </li></ul></ul><ul><ul><li>Easier for customer to “walk out of your shop” </li></ul></ul><ul><ul><li>Rate of change will be constant </li></ul></ul>Source: Gartner.

Performance Management Requirements

11.
<ul><li>Dropped packets = unresolved problems, especially in UC </li></ul><ul><li>Ensuring validation of new technologies requires </li></ul><ul><ul><li>Reliable 10 Gb capture </li></ul></ul><ul><ul><li>Large volume of data storage </li></ul></ul><ul><ul><li>Rapid search to locate root cause </li></ul></ul><ul><ul><li>“ Same size needle, larger haystack” </li></ul></ul>Moving at Data Centre Speeds

12.
<ul><li>Virtualized environments create black holes for ill prepared </li></ul><ul><li>Need visibility into VM-to-VM communication, even on same physical host </li></ul><ul><ul><li>Example: Multi-tiered applications </li></ul></ul><ul><li>Cannot analyse with tools that cannot be virtualized </li></ul><ul><li>Ensure integrated visibility into physical and virtual environments </li></ul>Virtualization

13.
<ul><li>Tools used to manage cloud services are often similar to tools used to manage internal infrastructures </li></ul><ul><li>Verify ability to track and analyze conversations from user to end destination in the cloud </li></ul><ul><li>Need in-depth WAN/Internet performance monitoring metrics: </li></ul><ul><ul><li>SLA enforcement </li></ul></ul><ul><ul><li>Tracking precedence </li></ul></ul><ul><ul><li>Locating and proving source of the problem: internal network, ISP, or cloud provider </li></ul></ul>The Cloud

14.
<ul><li>Solutions need visibility to validate performance </li></ul><ul><li>UC-specific metrics </li></ul><ul><ul><li>Jitter, quality, precedence settings, etc… </li></ul></ul><ul><li>View UC within context of overall network traffic </li></ul><ul><li>Separate Network and UC problems </li></ul>Unified Communications

15.
<ul><li>No brainer: It’s not the network, it’s the application </li></ul><ul><li>Need application-specific metrics and information </li></ul><ul><li>Integrate multiple monitoring perspectives </li></ul><ul><ul><li>Packets, NetFlow, SNMP, WMI, WAAS, NBAR </li></ul></ul><ul><li>Automated expert analysis </li></ul><ul><li>Baselines and intelligent alarms </li></ul><ul><li>Complete packet capture for problem resolution </li></ul>Increased Application Complexity
