Portals and SOA
I recently saw a blog entry mentioning an article relating SOA with the portal technology. It's not clear to me that this is really related. Yes, there are services, which can expose portlets, but are we saying that the composition of portlets inside a portal is identical to the composition of services by a composite application platform like Sun's CAPS ?
Here is the pointer to the document: A Service Oriented Architecture for Portals Using Portlets
Capacity of distributed infrastructure
In his blog entry Capacity Challenges Charles Betz ponders on the difference between the capacity management of mainframes and (the lack of ?) capacity management of distributed applications. I agree with all the points made in this entry, and would like to add some thoughts.
