Aspects of modern APM solutions
- 1. ASPECTS OF MODERN APM SOLUTIONS Fabian Lange, Head of Competence Center Performance codecentric AG
- 2. TODAYS CHALLENGES IN APM − Complex IT architecture − Technology mix − Large amount of IT infrastructure − Legacy does not go away − High rate of change − Multiple distributed development teams − Operations has little insight codecentric AG
- 3. TYPICAL(?) APPLICATION ARCHITECTURE Amazon EC2 Public Cloud Tomca t Jboss MQ VMware Sprin Private Cloud g Weblogi c codecentric AG
- 4. APM NEEDS TO PROVIDE − Single point for application health monitoring − APM solution has to support most existing and future technologies − Including End User Monitoring − High grade of automation − Deployment of the APM solution − Discovery of application architecture and code execution paths − Auto Configuration without expert knowledge − Change Adoption − Behavior learning − Meaningful data presentation − User view of transactions − How does the end user notice problems − Different views for various stakeholder codecentric AG
- 5. APM NEEDS TO PROVIDE − Scalable solution that can monitor − Tenths, hundreds, thousands of machines − Millions and Billions of transactions per minute − Thousands of users − Tools to narrow down root causes − Operations needs to find the needle in the haystack − Provide detail level information to responsible development team − Tools to monitor the application − Health − Load and Trends − Aggregation and Reporting codecentric AG
- 7. MTTR – MEAN TIME TO REPAIR − Is there a problem? − Baselines provide realistic thresholds − Where is the problem? − Distributed transaction tracing helps locating the root cause − Often connected to responsible dev team − What is the problem? − Drill Down allows finding details − Code Execution − Environment Metrics − User Data − Improving MTTR is the main reason for APM codecentric AG
- 9. LOAD AND PERFORMANCE TESTS − Monitoring is more important than test − Reality is different from test environment − Not reproducable problems happen in reality − Testing allows early feedback − No real customers harmed − Early tests are an integral part of agile methodologies − APM Solutions should support Production as well as Test environments codecentric AG
- 10. EASE OF USE − No time for complex tool − Time savers cannot require extra time − Not everybody is a performance expert − Collect enough data to troubleshoot problems without knowledge − Provide certain degree of automatic problem resolution − Still some problems require performance know how − Apple raised the bar for everybody codecentric AG
- 11. CHANGE − Business wants new functionality … − … and agile finally delivers − Application changes frequently … − … and with it its performance characteristics − Successful products create demand … − … which is often solved by adding resources codecentric AG
- 12. DEVOPS 1. Application Complexity cannot be handled by Operations 2. Operational Complexity is unknown to Developers − DevOps lets development and operations teams cooperate more closely − Developers learn how servers are set up and configured − Operations learn how applications are supposed to work − Developers learn the pain to be called during night − Operations learn development practices like test and version control − Major improvement for application − Development and Operations share responsibility for Applications − They need shared tooling codecentric AG
- 13. CLOUD − Cloud aka Virtualization is nothing new − APM Solutions can provide extra value − Determining the correct sizing at any time − Automatically reconfigure the application by load pattern − APMaaS − APM solutions can leverage SaaS models − Low cost of ownership − Pay Per use codecentric AG
- 15. SUMMARY − IT Applications change fast − APM Solution needs to adapt automatically − Support for multiple languages, frameworks and protocols − Operations need wide overview, but Developers need deep insight − An APM Solution has to provide both − Alerts need to be actionable − False alarms disturb − No red light should be ever ignored − APM solution should be able to alert the right thing codecentric AG
