Download as PPTX, PDF1 like1,730 views
The document outlines challenges in virtualization, emphasizing the need for a service-driven approach and effective capacity planning to meet service level agreements (SLAs). It identifies five key imperatives for managing virtualized environments, including mindset changes, ITIL processes, and end-to-end performance monitoring. Solutions discussed include tools for tracking transactions and optimizing capacity management based on performance data.
5 APM and Capacity Planning Imperatives for a Virtualized World
- 1. Five APM and Capacity Planning Imperatives for a Virtualized World Your hosts: Rich Fronheiser Frank Days Metron-Athene Correlsense October 17, 2012
- 2. Agenda 1. Challenges of Virtualiztion 2. The Five Imperatives 3. Summary/Q&A
- 3. Housekeeping • Presentation will last 30 minutes • Submit questions via the chat window • Slides will be made available tomorrow
- 5. 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)
- 6. 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
- 7. 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?
- 8. Traditional Tools are Insufficient Lack end-to-end performance management and capacity planning functions “CPU and “PING works, “SAN has low “Plenty of Storage & Memory are OK” Temp is OK” utilization” No hardware failures” Application Database X Server Server Fabric Storage Target Application Server SAN Performance SW Mgmt. SW Mgmt. SW Array Mgmt. SW SRM Tools “Plenty of capacity”
- 10. 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
- 11. 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
- 12. 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
- 13. 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

- 18. 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
- 19. Keep an Eye on your Top Ten Killers
- 20. Imperative 5: Monitor your IT Infrastructure End to End Who what response times Your users are experiencing SERVER WEB APP SVR PROXY MQ/ESB LDAP CORBA DCOM Web Services Datacenter
- 22. And Across your Infrastructure
- 23. 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
Editor's Notes
- #21: But why is this infrastructure in place? It is to host Applications that are required to support the Business.And the Transactions that flow through these applications are what allow the Business to be a Success.The founders of SharePath realized that by managing these Transactions is the most important thing because they are the lifeblood of the company.These transactions can be simple client Server transactions from Thick Clients talking to Databases <click>To more complex legacy Client Server transactions that connect multiple Back-End systems <click>To Web Transactions that now allow end-users to directly interact with your business systems and issue their own transactions.<click>And now these Web Technologies allow internal applications to be built to run the business.The point is that in this Complex, Heterogeneous technology architecture, the key thing to monitor is the Transactions of all types that flow through these systems.<click
