SOA filling the Gaps

More than a week ago I wrote a post on Oracle-Sun hardware in the light of Exadata 2 announcement. This announcement did not change my view before the acquisition and right after the Sun acquisition : Oracle is not a hardware vendor. This post is more technical than the previous posts mentioned above. Storage Hierarchy The schematic illustration above depicts schematically Storage Hierarchy. It includes internal memory, as well as external storage. The top of the hierarchy includes small, fast and expensive storage types, so the amount of storage of that types is limited. Sometimes the amount is also limited by technological constraints. As we proceed down the hierarchy the storage is cheaper and the amount of storage of that kind is larger, but the time required for accessing it is longer. The illustration does not show size ratios it shows only size order from smaller to bigger. It also does not differentiate between slow and slower storage included in the bottom ...

More than 10 years ago I was invited by Oracle Distributor or Oracle Israel (I do not remember if an Oracle's local branch was already established) to a dramatic announcement by Larry Ellison . Tel-Aviv was one of the cities in which you can watch it in real time. Oracle in cooperation with Sun announced the age of Network Computing. It was a good show. Larry Ellison broke a PC demonstrating that Microsoft 's Fat Client applications and data were lost.

It took some years until Google 's applications as well as other Web 2.0 Services vendors' products were used and more than 10 years until S aaS is going Mainstream and Cloud Computing services are used for some enterprise applications. Oracle and Sun anti-Microsoft campaign continued with J2EE vs. .Net wars. However, few years afterwar...
