From Components to Real-User Transactions to the Business: An Integrated approach to ITIL-aligned Capacity Management
September 2011
Rich Fronheiser, Metron-Athene, Inc.
Agenda
• A brief overview of ITIL Capacity Management
• The need for both component data and transaction data to do effective Capacity Management
• Monitor your business transactions
• Component data, business data and a framework for Capacity Management reporting, analysis, and planning
• An integrated solution for Capacity Management
What is ITIL (v3)?
• Good practice for IT Service Management
• Based on the Service Management Lifecycleo Service Strategyo Service Designo Service Transitiono Service Operationo Continual Service Improvement
ITIL Capacity Management
• Goal
• Purpose
• Objectives
• Scope
ITIL Capacity Management
• Three levels of Capacity Managemento Businesso Serviceo Component
• Requirements most often flow “top-down” and data and information “bottom-up”
Capacity Management Activities
• Iterative activitieso Monitoring, Analysis, Tuning, Implementation
• Demand Management
• Modeling
• Application sizing
• Modeling
• Storing data in the CMIS
• Completing the Capacity Plan
Capacity Management: Basic questions that need answers
• What is the expected business growth next year, and how will it affect our IT infrastructure?
• Which infrastructure items (servers and logical components) are serving which business applications and services?
• How will the relationship between the underlying components affect services levels and in a wider context the business that uses them?
• Which infrastructure components can be consolidated without degrading service levels?
Today’s Capacity Management Challenge
Planning ahead to achieve service levels while managing:
Business Constant Change, M&A
Service Complex, Multi-Tiered Architectures, SOA
ComponentHeterogeneous, Dynamic (Virtualization,
Cloud)
Many kinds of data needed
• Business data
• Service data
• Component data
• Financial data
• Relationships
Sharepath from Correlsense
• Allows you to monitor all real-user transactions in production
• Allows you to capture statistics from all the hops in the infrastructure
• Builds a map that shows the relationships between IT components even in very complicated environments
• Provides statistics for many different functions in an organization, including Capacity Management
Real-Time Detection – The Key to Business/IT Alignment!
• Transaction Metering
• Mapping and Modeling

How SharePath Works
o Patent pending technology
o No need for code change
o Stores 100% of all traffic –
by design
o No manual modeling
o Negligible overhead
Individual Transaction Path Detection
Transaction and Application Modeling
Auto-detection of dependency topology
Aligning Business and IT for Optimized Planning

• Component data can be captured or imported from
many different platforms and sources
• Business data can be imported into a central database
for use within Planning (trending and modeling)
applications
• Data can be captured and stored at all three levels of
ITIL Capacity Management – let’s see how Sharepath
data can be used within Athene to provide an
enterprise-wide Capacity Management solution

• How does SharePath integrate with Athene?
• How can it be used in the real-world?
• What value does it add?
Scenario
• Two applicationso Online Tradingo eBanking
• Hosted on multiple servers (UNIX & Linux)

“A model is a simplification of reality, built for a specific purpose”
Models
Modeling Overview - Trending
Utilization U
Non-linear change in Response
Time R
R Response times are non-linear Traffic related queuing Lists, cache, freeslots Constraints of OS and network Constraints of RDBMS etc Feedback loops Non-intuitive.
Modeling Overview - Analytical
Modeling Challenges
• Which servers are hosting which applications?o Understanding the relationshipso Understanding the volumeso Understanding the resource consumption
• Accurately assigning resource usageo SharePath accurately captures the workload split
Modeling - Baseline
Modeling – scenario one
Modeling – scenario two
Summary
• Business runs on transactions, transactions run on IT o Transactions are the missing link betweeno Componentso Serviceso Business
• By using SharePath to fully track transactions and Athene to optimize capacity management o Valuable business/IT data is createdo Unprecedented visibility is gained
• Enabling Athene to use this valuable data drives better capacity management decisions and predictions
