Understanding the Stability of Your EnvironmentUnderstanding the Stability of Your Environment

How confident are you during environment transitions and releases?

How often do changes (e.g. releases, upgrades, maintenance, issue handling) put your environment stability at risk?

How important is environment stability to you?Have you ever suffered from unplanned downtime?

How difficult is it for you to investigate accurately the root cause of instability of your environment?

Load TestLoad Test

End-to-end performance test based on anticipated production load in order to:► determine response times for various time-critical transactions and business

processes to ensure they meet service level agreement (SLA)► measure the ability of Internet applications to function correctly under load by

measuring transaction pass/fail/error rates

Interactive Test SessionsInteractive Test Sessions

A range of test sessions in which multiple test runs and re-runs are managed interactively with the customer:

Failover TestVerification of redundancy mechanisms while the system is under load

Targeted Infrastructure TestIsolation of each layer and/or component in an end-to-end application configuration

Performance TestEnd-to-end timing (benchmarking) of various time-critical business processes and transactions while the system is under load with a production-sized database

Network Sensitivity TestSet-up of various network activity scenarios (e.g. traffic, error rates), and measurement of their impact on a range of bandwidth-dependent applications

Volume TestMeasurement of batch processing under load

Environment ComparisonEnvironment Comparison


Environment Comparison Solution OverviewEnvironment Comparison Solution Overview

Helps to achieve and maintain environment stability

Identifies and analyzes changes and differences that put environment stability at risk by:► comparing different environments► comparing current environment with a historical snapshot or its golden baseline


End-to-End Environment ComparisonEnd-to-End Environment ComparisonIntegrative, top-down comparisonIntegrative, top-down comparison

Compares entire environment – applications and their underlying software infrastructure stack

► Applications► Front-end servers► Middleware► Databases► Messaging layer ► Operating systems► Hardware

Applies environment perspective rather than particular server or point technology

Compares logical environment architecture (i.e. independent of physical topology)


In-Depth Comparison In-Depth Comparison ““The devil is in the details”The devil is in the details”

Compares all facets of the environment► Architecture ► Configuration ► Bill-of-materials

Drills down to most granular level of configuration parameter in any configuration source

► Configuration files► Registry► Database schema / stored procedures► Reference data in database

Compares content of each environment component

► Version ► Size► Last modification


Comparison Analytics ApplicationComparison Analytics ApplicationFocus only on the “important stuff”Focus only on the “important stuff”

Applies comparison analytics in order to:► Classify changes and differences by

impact ► Prioritize and highlight critical

changes ► Ignore insignificant changes ► Compare inherently different

environments (test vs. production)

Visualizes comparison results for faster analysis

Leverages customizable comparison logic to ensure meaningful comparison

Cut Release Deployment and Stabilization TimeCompare production with pre-production environment after deployment to verify accurate transition of key release configurations

Cut Incident Investigation TimeCompare production environment with a golden baseline to identify changes that might be causing the incident

Cut Incident Investigation TimeCompare a non-working environment with a working environment to identify configuration differences that might be causing the incident

Avoid Risk of Negative Impact of ChangesCompare current environment with its historical snapshot before a change in order to identify and review all granular impact points caused by the change
