Gigamon: monitor your virtual servers better

  2. 2. © 2014 Gigamon Inc. All rights reserved. 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
  3. 3. © 2014 Gigamon Inc. All rights reserved. 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
  4. 4. © 2014 Gigamon Inc. All rights reserved. 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 Traffic Destination Traffic Destination Traffic Destination Monitoring/Security Solutions
  5. 5. © 2014 Gigamon Inc. All rights reserved. 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 vSwitch OVERLAY NETWORK UNDERLAY NETWORK Database Hypervisor Web Java LDAP AAA DB API DB API REST JSON API Web Java vSwitch Hypervisor vSwitch Web Java LDAP AAA DB API DB API REST JSON API Web Java
  6. 6. © 2014 Gigamon Inc. All rights reserved. 6 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
  7. 7. © 2014 Gigamon Inc. All rights reserved. If you can’t see it, you can’t control it Virtualization creates silos of IT hidden from security tools 7 Additional Challenge: Security
  8. 8. © 2014 Gigamon Inc. All rights reserved. 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

Gigamon Enables Virtual Server and Virtual Network Monitoring 9 Gigamon provides unmatched visibility into these environments: Traffic not traversing the physical network Distributed application architectures VMs on the move Hidden silos of virtualized IT Overlay/underlay networks
