Gigamon: monitor your virtual servers better

Download the whitepaper from http://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.

  1. Visibility intoVirtualized Data Centers

  2. 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 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. Why the Reduced Visibility? Distributed application architectures Traffic not traversing the physical network VMs on the move 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

  4. Challenge 1: Traffic not Traversing the Physical Network With virtualization, a lot of traffic doesn’t traverse the physical network Traffic Destination Traffic Destination Traffic Destination Physical Switch Monitoring/Security Solutions The result: Only part of the traffic is visible to monitoring at the edge Traditional monitoring tools can’t see new encapsulated traffic in overlay networks

  5. Challenge 2: Distributed Application Architectures Once monolithic, large applications are now running in a distributed application architecture Web Java Web Java AAA LDAP LDAP Web Java AAA Web Java DB API DB API JSON API JSON API REST REST DB API DB API Database vSwitch vSwitch vSwitch Hypervisor Hypervisor OVERLAY NETWORK UNDERLAY NETWORK • The results: • More east/west traffic handling applications • More difficult to monitor and troubleshoot

  6. Challenge 3: VMs on the Move 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 The result: Limited visibility and potential security gaps

  7. Additional Challenge: Security If you can’t see it, you can’t control it Virtualization creates silos of IT hidden from security tools

  8. 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

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