AGOS Grid Architecture for SOA

• Partners and Solutions

Building a Platform for Agile SOA with Grid

• Use Cases

AGOS: What for ?

• Context:• End of Moore law• Data size increase• Processing Time increase even faster (Data size + precision)

• AGOS Objectives:• Create an architecture and environment for integration of

• SOA business management with• GRID IT management

• Well fitted for data intensive and computational intensive applications:• Enact sub-parts of a BPEL workflow on dynamically allocated

resource• E.g.: Financial Simulations, Insurance, Revenue Management,

BIO… • Full dynamic scheduling of Services on GRIDs in the future• Integrated Management of SLO, SLA, QoS:

• Bottom to top:• Dynamic enforcement: Adaptive behavior

Why Run SOA on Application Grid?

2. Calls to backend systems for read only data generate load and result in performance hit

3. Using databases as a state repository and temporary store loads DB, incurs I/O cost

4. Building stateful services that are fault tolerance and performant. How?

5. Hitting backend

systems drives mainframe MIPs and results in performance hit

1. Response times for Web users / service consumer for synchronous requests

7. Sharing data between Web and SOA tiers

6. What happens if external service is unavailable?

2. Front-end calls for read-most data with cache to avoid hitting backend systems

3. Read directly from cache to improve response time and batch writes to improve throughput

4. Stateful business logic that is fault tolerance and performant built on data grid

5. Cache data and reduce traffic going to mainframe

1.Cache entire result of service invocation first time and reuse

7. Share data between tiers using cache

External ServiceBPEL

6. Cache result of external service calls giving fault tolerance for read only/ read mostly data
