The 7 Myths of Virtualized Application Performance


Published on

Whether you virtualize business applications like SAP, Microsoft Exchange and Java apps, or access apps like Citrix XenApp / XenDesktop - the dynamics and complexities of virtualized applications can cause significant performance and user experience issues that can diminish the benefits of virtualization.

The toughest performance problems to solve are the ones where users call and complain that "my application is slow". IT administrators struggle to determine the root-cause of the problem: is it the application? The virtualization layer? Is it the network? Database? Storage ...?

Watch this webinar with virtualization expert Dan Kusnetzky and find out how to deliver:

- Reliable performance assurance and user satisfaction
- Complete performance visibility across your virtualized environment
- Automatic, rapid root cause performance diagnosis for even the most complex performance problems
- Pre-emptive problem detection and alerting
- Rapid ROI through right-sizing and optimization

The 7 Myths of Virtualized Application Performance

  1. 1. The 7 Mythsof VirtualizedApplicationPerformanceWhy is My AppSo Slow?PresentersDan Kusnetzky (Analyst & Founder Kusnetzky Group)Bala Vaidhinathan (eG Innovations)
  2. 2. Virtualization Performance Dan Kusnetzky Distinguished Analyst Kusnetzky Group LLC© eG Innovations, Inc |
  3. 3. What is the problem?• Rapid change• Increasing use of virtualization technology• Emergence of cloud computing• Need to reduce costs at any cost• Maintain established systems Kusnetzky Group, LLC © 2012
  4. 4. Today’s coping strategies • Cross-functional tiger teams – Everyone brings the reports from their tools – Put the operational data jigsaw puzzle together – Determine the root cause – Determine what to do about it – Go and implement the agreed upon solution • Why isn’t this more simple? Kusnetzky Group, LLC © 2012
  5. 5. Where is the Problem? Active Directory SQL SAN Switch EnterpriseClient Apps Network Web on XenApp on ESX ZDC on VMware ESX VMware ESX Profile Server License Server Oracle vCenter What is the root cause of the service problem? Network? VMware? AD? SQL? Storage? Profile Server?
  6. 6. Why don’t today’s established performance tools do the job?• Blind — tools look at details rather than the whole picture• Static — tools were designed for static environments• Slow — a holistic view has to be built one piece at a time• Complex/difficult — many different disciplines must be involved• Costly — Many organizations don’t have all of the different types of expertise• Fragmented — operational data is maintained everywhere and nowhere Kusnetzky Group, LLC © 2012
  7. 7. What would an ideal tool look like?• Complete visibility — sees everything from the end user to the data center• Aware of all forms of virtualization — see into virtual desktops, applications, systems, networks and storage• Auto diagnosis — constant monitoring and predictive analysis producing automatic root cause analysis• Simplified — Built in intelligence to make things simple• Pre-emptive — Proactively identify issues before they can turn into problems• Cost effective — Reduce the cost of operations• Comprehensive — Manage performance across all silos from the end user to the data center Kusnetzky Group, LLC © 2012
  8. 8. 7 Myths - Fact or Fiction?1. Virtualization makes performance management easier2. Resource reservation ensures that VMs don’t interfere with each other3. Virtualization is just another silo that can be managed independently from other tiers4. Virtualization platforms already include all tools and metrics needed to manage the virtual layer5. The hypervisor view of virtual machines is sufficient to manage VMs6. VDI performance management can be done using tools that support Virtual Servers7. Scaling is linear - more hardware means more performance Kusnetzky Group, LLC © 2012
  9. 9. Audience Poll“What are your biggestvirtualization challenges?” Virtualization performance management is more complex Performance and user experience problems Inadequate performance management tools Lack of visibility into VMs and dependencies VM sprawl© eG Innovations, Inc |

  11. 11. Myth #1 “Virtualization makes performance management easier” Scope for performance management remains the same  10 servers, 30 guests => 300 virtual machines to monitor Higher complexity because of resource sharing across VMs  Guests share CPU, memory, disk, network resources  A single malfunctioning application in a guest can impact performance of all other VMs Physical Virtual© eG Innovations, Inc |
  12. 12. Myth #2 “Resource reservation ensures that VMs don’t interfere with each other” Slow Database Queries Streaming Media App Shared resources become bottlenecks: • Network • Storage • Compute • Apps Disk reads • Desktop Excessive disk reads by the one VM slows down application within another VM© eG Innovations, Inc |
  13. 13. Myth #3 “Virtualization is just another silo that can be managed independently from other tiers” “Myapplication is slow!” USER FIREWALL WEB SERVER APP SERVER DB SERVER A problem in one tier can affect all the other tiers. Is it the network, database, app server, or virtualization tier? © eG Innovations, Inc |

Myth #4 “Virtualization platforms already include all tools and metrics needed for performance management” “My application is Looks Not our fine Not mine slow!” problem either Talk to the other guys LAN ERP Admin Application End User Sys admin Admin Admin Everything Domain Is OK admin Firewall All lights admin Are green VMs are lightly The server is working loaded OK Database Admin Server admin Virtualization We don’t No other admin see anything complaints wrong IT Service Manager© eG Innovations, Inc |
  15. 15. Myth #5 “The hypervisor view of virtual machines is sufficient to manage VMs” 100% • The Outside view shows the portion of physical Resources of the Physical VM4 resources used by each VM (CPU, disk, memory) 32% • Provided by the virtualization hypervisor Machine VM3 20% • Useful for capacity planning and identifying certain VM issues VM2 25% • Does NOT show why a VM is consuming resources VM1 15% 0 100%Resources of the Physical Machine • The Inside view shows the portion of resources allocated to 40% VM4 a VM that are used by each application and each user of the VM 20% 32% 12% • Provided by the guest OS (for Windows: WMI) VM3 25% 60% 20% • Useful for user load balancing, identifying guest OS issues, misbehaving 10 45 5 applications, and unauthorized user activities VM2 30% 25% % % % VM1 60% 10% 15% • Does show why a VM is consuming resources, accelerates fix 0 Apps inside a VM © eG Innovations, Inc |
  16. 16. Myth #6 “VDI performance management can be done using tools that support Virtual Servers” Performance management for VDI is extremely unique as you Virtualization need a solution that combines multiple different performance management methodologies Brokers VDI and Desktop Support Systems Microsoft Hyper-V Citrix XenServer© eG Innovations, Inc |
