Controlling complexity is a

major IT issue . . .


IT and the enterprise

Application performance is key to enterprise productivity and

business success.

Transactional applications and business services based on aggregates of

these applications are the business visible component of IT.

Performances are critical for the overall productivity of the enterprise.

IT operation must deliver performances are in line with business expectations.

The current economic conditions favor short-term returns on

investments.

IT organizations tend to favor tactical over strategic initiatives.

In light of the poor economic situation, reducing costs tops business goals.

There's increasing pressure to prove business benefits of any IT spending.

Productivity equals application performance

The key to productivity in interactive applications is

response time:

.1 second is instantaneous.

1 second is when a response time is perceived.

10 seconds is when users lose focus on the interaction.

Basic rules

Simple and frequent tasks: 1 second or less

Common tasks: 2 to 4 seconds

Complex tasks: 8 to 12 seconds


But can IT organizations deliver?

Cloud-based services are on the horizon


What will be naturally in the cloud in 2015?

Standardized business logic

Horizontal business applications

Multitenant business process platforms

Simple, standardized infrastructure services (IaaS) like storage and

compute power

What will remain on-premise?

Most custom-build applications

Application implementing customers intellectual property relevant and competitive business logic

How will we manage complex hybrid applications?

The application performance management concept

Java EE and .NET are at the application core.

Java EE applications servers seen as the critical technology

Number of entrants in the monitoring of these applications, closely followed by

an interest in .NET

Acquired by larger IT management vendors

BSM and application mapping

But the granularity of dependency mapping at the application level isn't

sufficient to be a template for transaction performance management

APM evolved into a broader monitoring solution.

Complex applications, using Web services, SOA, and multitier aggregation

Problems can now come from a number of directions .

APM started to include other forms of monitoring, such as end user experience,

infrastructure, and database to complement the Java EE and .NET monitoring.


The business transaction monitoring concept

Applications are really seen through business transactions.

Performances are perceived at the transaction level.

Transactions are not created equal.

Global monitoring is not sufficient to debug transaction performance

issues.

Business transaction monitoring, with the possibility to map in real time at

the individual transaction level, appears alongside APM solutions.

Business transaction monitoring solutions provide transaction visibility and

problem identification but not the monitoring depth of APM.

Is the ideal solution an APM-BTM convergence?

Collect transaction response time

Zone of customer expectationMap the transaction componentsZone of customer expectationMonitor the transaction components



Collect response times by transaction, and determine the first level-

alerting criterion.

Understand and map all the components of the transaction.

Monitor applications themselves. This includes all types of applications.

Monitor performance of the database(s).

Monitor the physical and virtual components of the infrastructure.

Combine all these parameters.

Provide all this information on a single-pane-of-glass dashboard.

Conclusion

An application performance management solution:

Understands the infrastructure supporting the transaction

Collects data and events from all transaction components, including

virtualization and cloud

Integrates all events and data on a single pane of glass for proactive

analysis

Guide IT operations in identifying the component at fault

Determine transaction criticality

Allows deep dive on component (of all nature) at fault


Recommendations

Understand the complexity level of your business services. This should be

assessed in a business dimension and in an IT operation dimension but with an eye

to whats coming down the pike.

Inventory the monitoring products installed in your operation. Conduct a

thorough assessment of the value and potential for integration of each of these

products, sorting what should be replaced and what should be kept.

Conduct an analysis of the solutions available on the market. Create a gap

analysis between installed solutions versus a comprehensive performance

management solution using the Forrester reference model.

Conduct an economic analysis. This analysis should take into consideration the

efficiency of the end result. For example, how many brownouts and downtimes

could have been avoided with the right solution, and privilege these long-term

benefits over short-term savings in license costs.
