[infinispan-dev] Infinispan within JBossAS

Hi guys,

I'll be doing a short talk about JBoss 6 & Infinispan at a local conference:

"This presentation introduces Infinispan, the new underlying data caching and replication 
infrastructure included with the upcoming JBoss AS 6. Infinispan is an Open Source library 
that can be used independently of JBoss AS to let you build dynamic and highly available 
data grids that scale to the order of thousands, while offering a large number of enterprise 
features."

I need some help to identify the key benefits of using Infinispan in the context of AS.

- Why is it going to be better from JBoss Cache?
- What are the major use cases we are addressing?

The obvious ones are

- smaller memory footprint
- faster

But I need more, in terms of how it will affect

- session/sfsb replication
- jpa/entity caching invalidation, 2nd level caching
- other?

Beyond the "standard" usage of Infinispan replacing JBossCache in AS, I need usecases of 
datagrids used in the context of AS deployments. Is it going to be used primarily as a 
read-mostly cache? Do you have some examples?

I'm trying to imagine applications that would really benefit by the JBossAS/Infinispan 
combination when deployed in the cloud in really large numbers (e.g. hundred of AS 
instances). Would a special architecture design would need to be used in this case?

Finally, do you have some standalone Infinispan usage examples?

I think it will be great if we can associate/match Infinispan (within AS) to real people 
problems and usecases.

Thanks for the help!
