3 The Cloud: a new era of utility computing All types of computing are available as a service via global network Applications: Business Applications Software as a Service (SaaS) Platform: Databases and Middleware as a Service (PaaS) Infrastructure: VM, OS, Servers and Storage as a Service (IaaS) 3

4 Oracle Fusion Middleware portfolio Bringing Oracle Fusion Middleware as a Service to the Cloud Social Mobile Web Business Process Management Service Integration User Engagement Content Management Identity Management & Security Business Intelligence Data Integration Complete Open Integrated Best in Class Development Tools Cloud Application Foundation Enterprise Management 4

5 Oracle Cloud Application Foundation What is needed for such a middleware PaaS service? What is the minimal set of components needed to host SAAS-oriented applications effectively? a lightweight and standards-based Java server a Java framework, specifically designed for building cloud applications an in-memory data grid for caching and clustering elasticity to adjust to workload variations integrated traffic management to route traffic throughout this elastic infrastructure virtualization for optimal use of server resources simple provisioning typically via self-service interfaces 5

29 HA with Rolling Upgrade Zero Server Infrastructure Downtime Upgrade a running cluster with a patch, maintenance pack or minor release without shutting down the entire cluster During the rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while the other servers in the cluster continue to host your application You can also roll back the patch, maintenance pack, or minor release in a similar fashion Node 1 Node Mgr Managed Server App 1 Maint Pack x.y Node 3 Node Mgr Managed Server App 1 Maint Pack x.y IP Unicast Node 3 Node Mgr Managed Server App 1 Maint Pack x.y Node 4 Node Mgr Managed Server App 1 Maint Pack x.y 29

30 Backup and Recovery Certified Solution Based on Disk Replication Simple solution based on file system copy for middle-tier components Use RMAN for Oracle Database Support for online backups Can integrate with existing Backup/Recovery tools Can be scheduled through Enterprise Manager or cron jobs LDAP, Policy, Credential Data Fusion Middleware WebLogic Middle Tiers Application Data Application Data Oracle Binaries Exploded Archives Metadata External Files Backup Storage 30

31 Disaster Recovery Architectures Web Tier Active Site Web Server Web Server Global Load Balancer Web Server Standby Site Web Server Web Tier Middle Tier Binaries Configuration Non-critical files replicated separately File Replication from critical Technology data. Binaries Configuration Middle Tier Data Tier Transaction Logs JMS Messages Application Data No need to struggle to synchronize file and data replication Critical Datagard data stored, managed, GoldenGate and replicated together Transaction Logs JMS Messages Application Data Data Tier 31

32 Application Server Scale Out Issues Scaling cached data Difficult to scale clustered cached data reliably Consistency, expiry, location Scaling state State is heavy and expensive Difficult to manage state independent of application server Scaling database transactions Difficult to buffer database from spiky application layers yet maintain transactional integrity Managed Server1 WebLogic Domain Node Manager WebLogic Cluster Cached Data??? Shared State??? Transactions??? Database Managed Server2 32

33 Weblogic and Coherence*Web Standard Weblogic Server HTTP session replication Optimized HTTP session replication option with Weblogic 33

34 Standard Two-Tier Weblogic Cluster Typical Two-tier WebLogic HA Cluster Architecture Web Tier Servlet engines handle HTTP requests Sessions are replicated between Servlet engines according to defined replication groups Servlets use replica-aware stubs to look up EJBs in the Object Tier Primary/Replica pair are distributed according to defined replication groups and order of precedence rules Object Tier Object Tier provides EJB container services, JCA adapters, JDBC, LDAP or other connectivity HTTP/JSP Sessions WebLogic Server EJB JDBC WebLogic Server 34

36 Optimized Web Tier Dedicated session grid & session-less traffic processors Engine Tier Engine Tier is stateless Optimized for request processing Engine Tier nodes may be added/removed with no impact on ongoing sessions Session Tier Stand-alone (POJO) Coherence nodes Zero code change for applications that use standard WebLogic session replication or a plug-in solution from another vendor Sessions are shared between all Web-tier instances, even different applications Low memory/cpu overhead, fast startup Easily handles large sessions (10MB+) Optimized networking, serialization HTTP/JSP WebLogic Server Sessions Coherence*Web 36
