I came across this interesting post: How Mashups Could Eliminate Integration Projects by Loraine Lawson. In a related post, she refers to John Crupi’s article Enterprise Mashups Part I: Bringing SOA to the People which I would recommend to readers who want to understand JackBe’s take on defining mashups. Anyway, Loraine’s post led me to Ron Schmelzer’s ZapFlash.
Here are some excerpts of Ron’s article that caught my eye, with my take on it:
A year or two ago, assuming that a mashup was a web browser-based, static, user interface composition of web-based functionality would be a reasonable presumption. But in the enterprise context, none of those assumptions necessarily hold – we might want non-Web access to mashed applications, we might want to change them regularly, and we might want to mash up information that exists below the user interface abstraction. For sure, Web mashups might embody the ideals of the original mashup concept, but we now have the desire to mash up a wide variety of IT resources from application to infrastructure to data that might be exposed with a wide range of interfaces – or without. And, it’s the desire to mash up information freed from the application that diversifies the mashup term to include the concept of the data mashup.
My take: This hits the point right on what we at JackBe have been saying all along about mashups. While some mashups are done purely in the UI/Browser, in the enterprise, such mashups need to be supported by a new tier, the mashup tier, which sits between the presentation and business tier. So enterprise mashups will have some mashing done in the client, but most of the mashing happens in server side where security, governance, policies can be applied before any mashing can happen in the client.
There are many scenarios for composing data, but some are better suited for static, tightly-coupled, IT-driven, non-Service Oriented form. In fact, 80% of the value that businesses derive from data come from the 20% of fixed, highly optimized data integration approaches implemented over decades. In this realm, traditional data integration approaches retain high value. However, it’s the other 80% of data integration requirements, most of which come from the need to meet short-term, often ad hoc, integration requests that cause 80% of the problems. Anyone who has lived long enough in the enterprise IT space knows that business-driven requests for reporting, forecasting, analysis, or other interpretations of data can present significant complications and cost to the IT organization. The reason for this is that the IT organization is set up to meet the recurring needs of the business and not “situational” needs for information.
My take: This highlights another issue which we have been talking about at JackBe about the long tail & enterprise applications need which was so nicely discussed here by Dion Hinchcliffe.
Bottom line: Something new and interesting is happening in the enterprise architecture space. A new flexible and agile tier is being introduced in the architecture to meet the increasing demand on IT and add value to existing architecture, applications, services and data. Question is, are you embracing this inevitable change? If not, it’s still not too late. 🙂
