Managing application performance for cloud apps bmc

  1. 1. Managing ApplicationsPerformance of Cloud-basedapplicationsDebu Panda
  2. 2. Why performance to Cloud based application is critical Most cloud based applications affect end-user …So it directly impacts your revenue© Copyright 1/11/2013 BMC Software, Inc 2
  3. 3. The Complication – Cloud is Different Day 2, 3, 4… …With new cloud complexity: Traditional challenges remain: o Incredible scale o Varied infrastructures o Local and public resources o End-to-End application monitoring o Highly movable workloads o Multiple data sources o Ongoing new/ retired services o Security considerations o End-user expectations + mobility 1. Service Level Enforcement 2. Proactive Service Performance Management 3. Continuous Resource Optimization An integrated, holistic approach across all 3 requirements© Copyright 1/11/2013 BMC Software, Inc 3
  4. 4. Complexity in Architecture Is the application performing? IaaS Can I complete my transaction? Virtualized or Multiple Data Centers Content Managed Services Delivery (PaaS) / SaaS Networks (CDN)© Copyright 1/11/2013 BMC Software, Inc 4
  5. 5. Your GOAL: Meet the user’s ongoing expectations for servicequality© Copyright 1/11/2013 BMC Software, Inc 5
  6. 6. The Challenges Highly distributed systems No visibility Many tiers – App, Cache, - Impacted users - Actual errors on browser Messaging, - Offending component NoSQL/Hadoop, RDB, - The problematic VM or MOM, server No control over the - The problem in Java physical hardware or app layer, Caching, or when using SaaS Persistence tier Network problems Improperly tuned application tier The risk is very high as the time, effort and cost of diagnosing goes high© Copyright 1/11/2013 BMC Software, Inc 6
  7. 7. Approaches for Managing Performance for Cloud-basedapplications End-user monitoring Applications Monitoring - Synthetic user - Transactions and deep dive monitoring - Real User Monitoring - App Infra monitoring Logs© Copyright 1/11/2013 BMC Software, Inc 7
  8. 8. Synthetic Monitoring 1) Transaction working? 2) Yes, try again in 5 minutes Pros - Consistent data for trending and availability - Does not require real user traffic - Can measure DNS and 3rd party content Cons - Only monitors a small part of the web site/application – many problems missed - Only monitors a fraction of time intervals – can miss sporadic problems - Only represents a limited number of reference user locations - Website/application changes can break scripts - Additional transactions can generate overhead© Copyright 1/11/2013 BMC Software, Inc 8
  9. 9. Real User Monitoring Pros - Monitor actual business processes - SLAs based on real user experience, not limited scripts - No need to set up and maintain scripts - No need to set up dummy accounts Cons - Requires real user traffic - Volume of collected data can be very large© Copyright 1/11/2013 BMC Software, Inc 9
  10. 10. Real User Monitoring: Network Capture of user traffic 1) Span port or network Tap 2) Continuous capture Pros - Rich network-level data - No overhead introduced - Can see the majority of real user traffic - Automatically detect applications - Done by a Cloud-agent in the web server if network tapping is not available Cons - See traffic that reaches origin – miss 3rd party objects & cached pages - Requires ability to capture/tap the traffic© Copyright 1/11/2013 BMC Software, Inc 10
  11. 11. Real User Monitoring : Browser-based measurement (w/JavaScript) 2) JavaScript execution 1) Instrument pages 3) Record measurements Pros - Most accurate measure of browser render time - Includes 3rd-party content and frames in measurements - Can measure cached content (ADN) Cons - Instrumentation of pages can be difficult - JavaScript instrumentation can cause logic issues if not done correctly - Only measures HTML, cannot measure certain types of objects (like pdf, or images) - Will not detect page errors - No packet-level metrics© Copyright 1/11/2013 BMC Software, Inc 11
  12. 12. Real User Monitoring :Client agent 1) Install agent 2) Record measurements Pros Accurate measurement of traffic at the mobile device Can capture other device statistics (CPU, memory, etc) May be able to capture mobile app performance Cons Requires installation of agent on client machine (intrusive) Or requires instrumentation of the applications (need developer)© Copyright 1/11/2013 BMC Software, Inc 12
  13. 13. Deep-dive Monitoring Applications Install agent on app serverTwo approaches • Server-centric • User / Transaction based problem isolation© Copyright 1/11/2013 BMC Software, Inc 13
  14. 14. Server Centric Monitoring Monitor Application Server/JDBC/JMS resources Monitor summarized end-point invocations Use JVM diagnostic tools to find JVM issues© Copyright 1/11/2013 BMC Software, Inc 14
  15. 15. Challenges in Server Centric Monitoring Old generation products are not suitable for Cloud - Do not work well in virtualized environment Manual correlation of issues - Challenging in dynamic/elastic environment Difficult to identify impacted users and issues with specific transaction Difficult to identify problems are in actual tiers - Network, CDN or external services For PaaS: Depend upon your PaaS vendors for their monitoring metrics© Copyright 1/11/2013 BMC Software, Inc 15
  16. 16. Transaction-based approach Identify top level transactions and monitor health of transactions and monitors its health Requires agent to be installed on the Application Server© Copyright 1/11/2013 BMC Software, Inc 16
  17. 17. End-to-end APM – combining power of end-user monitoringwith deep-dive From the data-center perspective Service Level Enforcement CDN DB Tier App Tier End to End Web Tier End User Experience Mgmt Deep Diagnostics From the end-user perspective© Copyright 1/11/2013 BMC Software, Inc 17
  18. 18. End-to-End Performance with Real User / TransactionDriven Diagnostic AppVis Continuously monitor end user details transactions Integrate your transaction driven deep-dive monitoring tool with real-user monitoring Complete visibility to applications and end-users© Copyright 1/11/2013 BMC Software, Inc 18
  19. 19. DEMONSTRATION© Copyright 1/11/2013 BMC Software, Inc 19
  20. 20. Summary Cloud applications are more complex than traditional applications Diagnosing problems in application deployed in the cloud could be challenging You can use a User transaction based tool to identify bottlenecks in your application© Copyright 1/11/2013 BMC Software, Inc 20
