Last few months working on few pre-sales proposals, seeing couple of trends/patterns in many of them. Many of the projects customers are planning to start have a cloud piece. Many of the customers are using SFDC (Salesforce.com) or planning to move particularly in media, hospitality industries. Subscription based cost is driving a lot of technology choices. Customers are becoming very cost sensitive and want a very flexible costing model and execution models, where they can pay as they use in buy, build or cloud choices.
From solution perspective, It becomes new challenges around how to integrate with cloud, how to handle security, how to handle RASP (Performance in particular).
Other than the cloud trend, the other trend is the regular debate of orchestration vs choreography. So for every industry or cross-industry problem there are many packaged applications, now these applications also provide regular supporting peripheral/plumbing functionality. For example, an Order-Management App will have its own inbuilt workflow, will have OOB UI to manage the process flow or administration. Now the debate is whether to use the App's such in-built features or to use an esb/bpel layer to unify these functionalities centrally across applications. That's the choreography vs orchestration debate, ESB for stateless choreography and BPEL/BPM for stateful orchestration.
Either way positioning an ESB is easy, with all the security and visibility story around services. Positioning the BPM story is a challenge, customers in hurry resort to point-to-point integrations and some even don't go for commercial esbs. That's another trend I saw open-source ESBs the entire story around JBI, Mule, Fuse, Spring, OSGi etc.
Another trend I see is customers are more interested in data/dw, bi/reporting, mdm etc. And different compliance requirements are driving lot of strategic projects in this area.
My next interest is to find architecture patterns, how soa/bpm/e2.0 can be used both strategically and tactically, particularly oracle soa.
