  12. 12. Elastic Caching for WAS V8.5.5 WebSphere eXtreme Scale entitlement with WAS • Customers can now develop with caching in mind • Benefits for developers – free access to caching for unit testing on developer’s desktop • Benefits for business – improvements to performance at lower cost • Ability to enhance customer experience for web sites which can also improve revenue Web Server Tier App Server Tier Data Cache (WXS) Back-end Systems Database Tier  WAS Network Deployment includes full entitlement to eXtreme Scale  WAS includes entitlement to use eXtreme Scale for Session Management and distributing the WAS DynaCache service
  13. 13. Web Cache Example WAS v8.5.5 provides support for WebSphere Web Cache, a.k.a. DynaCache, enabling a local caching service for simplified development of applications  Local server cache for dynamic web content webCache  Enables developers to easily develop / test applications for local server caching solutions Servlet/JSP/ application  Same API as full WAS  Optional disk offload DistributedMap API cachespec xml  LRU replacement policy  Run as local server cache in production or move applications unchanged to distributed caching via WebSphere eXtreme Scale 13 In-process web cache (dynacache) Disk offload
  14. 14. WebSphere Extreme Scale for Distributed Web Caching Use WebSphere Extreme Scale for greater data elasticity and higher caching qualities of service  Massive data volume with Servlet/JSP/ application linear scalability  Elasticity: add more cachespec xml instances dynamically and runtime redistributes data automatically. WebSphere eXtreme Scale Client Grid Container Servlet/JSP/ application cachespec xml Grid Container DistributedMap API Catalog Server WebSphere eXtreme Scale Client 14 Grid Container … – No need to store cache at every application server. Grid Container Grid Container  Cache consistency  Configurable number of replicas: balance between read and write operations. DistributedMap API Grid Container WXS Caching Tier

  18. 18. WAS - Intelligent Management Application Edition Management Server Health Management (Part of WAS ND and WAS for z) SLA based Dynamic Clustering Intelligent Routing and SLA Enforcement StockTrading 1.0 StockTrading 2.0 StockTrading 3.0 Costs Up to 45% less hardware Up to 60% less administration Up to 45% less software Up to 90% fewer outages Source: Based on 60+ WebsSphere Virtual Enterprise Value Assessments done to date by IBM for real customers
  19. 19. Application Edition Management Seamless upgrades from one version to the next… What is Application Edition Management? − Seamless upgrades without interruption − Deploy new applications easily − Test specific version with a select group of users Benefits − Easy validation of new versions − Supports “rolling” upgrades − More agile and flexible deployments − Concurrent activation − Upgrade applications without incurring outages  Keeping critical business apps up and running
  20. 20. Health Management – Preventive Action Avoids Outages Sense and respond to problems before end users suffer an outage  Proactively deal with application issues before they become acute problems … automatically  Administrative policies for health conditions and associated corrective actions − Examples: Memory leaks, slow response times etc…  Provides insight! Results In: − Better availability − Less administration − Satisfied end users
  21. 21. Health Management – Health Policies Helps mitigate common health problems before outages occur  Health policies can be defined for common server health conditions  Health Policy: If (Condition) then (Action) e.g: • Notify administrator (send email or SNMP trap) • Capture diagnostics (generate heap dump, java core) • Restart server  Custom health actions are commands or scripts  Excessive response time means you are monitoring what matters most: your customer's experience!  Each health policy can be in supervise or automatic mode. Supervise mode is like training wheels to allow you to verify that a health policy does what you want before making it automatic. Health Conditions • Excessive request timeouts: % of timed out requests • Excessive response time: average response time • Excessive garbage collection: % of time spent in GCs • Excessive memory: % of maximum JVM heap size • Age-based: amount of time server has been running • Memory leak: JVM heap size after garbage collection • Storm drain: significant drop in response time • Workload: total number of requests
  22. 22. Dynamic Clustering Proactively provision and start or stop application servers based on workload demands to meet Service Level Agreements  Associate service policies with your applications •Let WebSphere manage to the service goals  Optional: programmatically respond to spikes in demand •Add or reduce application server instances as appropriate  Pool middleware resources for higher utilization  Decrease administrative overhead required to monitor and diagnose performance issues  (Since V8.5.5) Web server plugin as alternative to Java ODR.
