Summary
Complex Event Processing on Event-Driven Networks, In-Memory grid, and parallel pro-
cessing with the following entity aggregation are not isolated standalone technologies that
can be evaluated versus / instead of a service-oriented approach but parts and supporting
blocks of SOA in a broad prospective. Similar to the cloud methodology and mechanisms,
the Cloud Service / Resource Broker is not someone who is trying to upsell you the remote
hosting services, which are provided by the company two blocks away.
SOA and Cloud are quite interconnected, complementing each other with atomic and trans-
portable units of work at one side (genuine SOA) and virtually unlimited distributed com-
puting resources (Service Grid and Canonical Resources SOA patterns, which are provided
by cloud) at another.
With recent developments, Oracle can practically provide all the necessary building blocks
for all implementation tiers and frameworks, both on-premise and offsite. Complex silo-
like applications, such as Salesforce, are now available on cloud. They can be easily integ-
rated with the local Oracle SOA Suite, or clouds from other vendors can be linked to
Oracle Cloud Farm with not much effort. This approach will allow you to boost your pro-
cessing right away without making any significant investments in your local infrastructure,
paying as you go. For those who already have corporate data centers with service infra-
structures of any level of maturity, a more gradual pattern-based approach would be wiser.
Just remember where we started; each pattern is the answer to a particular, repeatable, and
identifiable problem. Identify your problem first.
