Runtime Infrastructure– Availability– Workload Management– Monitoring

Manageability Support– Unified Notification– Central Topology, Distributed Deployment– Backup/Recovery

Server Infrastructure for GridHigh Availability

Web Cache

• Virtualized cache• Surge protection

Oracle HTTPServer

• Metrics-based load balancing• Process monitoring and notification• Auto discovery of OC4Js

OC4J

• Instrumented runtime• Fast failover notification• Distributed config mgmt

RAC

• End-to-end tracing• Scale on commodity hardware• Virtualized database resource

Web CacheA Virtualized Grid Resource

• Make more effective use of low-cost, existing hardware– Enables high hit-rate caching (which improves performance and scalability)

• Maintain quality of service with workload management– Improves system reliability

• Manage the end-user experience– Supports end-user performance monitoring and flexible deployment options

Web Cache

HTTP Server

J2EE ServerDatabase

What is Web Cache?

• Reverse proxy cache and

compression engine

• Deployed between

browser and HTTP server

How Web Cache Works

1. Client sends HTTP request2. Web Cache responds immediately if cached object is available 3. If object is not in cache, Web Cache requests object from Application Server4. Application Server generates response (may include Database queries)5. Application Server responds to Web Cache6. If response is cacheable, Web Cache retains a copy for subsequent requests7. Web Cache compresses page and responds to Client

Cache Clustering

• Solution: clustering on the Grid– Virtualizes cache instances into a single logical cache – spreads out load

• Automatic content provisioning– partitions content space for increased cache capacity– replicates popular content for performance and high availability

• Benefits: improved scalability, availability and capacity of cache tier

Issues: Cache capacity

limited to individual machine resources

Grid-Related Standards Activity

Oracle commitment to open standards process

– WS-I, OASIS, W3C, GGF Grid standards build on web services

standards– WSDL emerging issues– OGSI– Grid standards are relatively immature

Goal: Commercialization of grid technology– Standards play a central role

Developing for the Grid

Existing Applications Just Run– Expose existing apps as grid-enabled services

New Applications– Develop web services

Use JDeveloper ADF– Web services are grid-enabled in iAS, built on the

J2EE platform

Leverage a Framework and Visual Tools

Oracle Application Development Framework

– Standards based patterns– Service oriented architecture

CHOICES

Productivity with choice.

Summary

Enabling technologies for enterprise grid computing are here today in Oracle Application Server 10g

– Implement one solution from many resources– Manage many resources as one

Existing applications can benefit now from grid computing.

– You do not need to sacrifice choice or openness to achieve productivity and performance
