5 apm and capacity planning imperatives for a virtualized world
DESCRIPTION
The proliferation of virtualized applications has greatly increased the complexity of capacity planning and performance management. Monitoring and forecasting CPU utilization is no longer enough. IT operations and capacity planners now must understand and optimize their applications and infrastructure from the end user to the data center. Join Correlsense and Metron-Athene for an online seminar which will explore key performance management and capacity planning strategies for a virtualized world. We will discuss: What you need to know about capacity management when operating in both physical and virtual environments How performance monitoring in virtual environments relates to your capacity management goals What is unique about capacity and performance management for virtualized applicationsTRANSCRIPT

CHALLENGES OF VIRTUALIZATION
Managing Entire Environment
Planning ahead to meet biz requirements and SLAs while managing:
Business Constant Change, M&A
Service Complex, Multi-Tiered Architectures, SOA
Component Heterogeneous, Dynamic (Virtual, Cloud)
Moving from Physical to Virtual
• Virtual infrastructure is shared• Can be over-subscribed• Control in the hands of resources manager• App performance before and after migration is
critical
Maintaining SLAs
• SLAs are still in place even if you virtualize• Load testing might not provide enough info• How do you monitor desktop response time?• How do you know your end to end performance?

THE FIVE IMPERATIVES
Imperative 1:Changing of Mindsets• Shift to virtualization requires a change of mindset in many
data centers
– Technology moves work to pockets of adequate capacity
– Proper amounts of capacity on a host level is no longer focus
– Ensure adequate headroom for periods of peak demand
– Virtualization provides savings only if capacity managed
Imperative 2: ITIL – Service-Driven Approach• Driven by:
– Shared infrastructure/resources– Centralized storage– Reliance on network resources
• Strong processes to drive today’s virtualized data center– Incident Management – Problem Management – Service Level Management
• Proper CM ensures fewer problems and that SLAs are met
Imperative 3:Focus on Services and SLAs• ITIL-based approach• The service lifecycle is the central focus• Crucial that SLAs are developed that are
– Specific– Measurable– Achievable– At an acceptable cost
• Ensure enough (but not too much) capacity to meet SLAs
Focus on Services and SLAs
• Measuring end-to-end transaction time for production transactions is necessary to see if SLAs are met
• When SLAs are not met, model scenarios to determine infrastructure changes
• APM data helps find opportunities to right-size virtualized infrastructures

Imperative 4: Understand your Complete IT Picture
• Monitor critical application performance across physical and virtual environments
• Understand your true end-user experience
• Verify performance in the new virtual environment

Summary
• Virtualization brings many challenges– P2V migrations
– Applications environments
– Traditional tools are insufficient
• Solutions– SharePath to fully track transactions
– Athene to optimize capacity management
– Using performance data for better capacity management decisions and predictions
