Enterprise Mashups: The New Face of Your SOA

Bringing value to the enterprise

Enterprise mashups, one of the hottest Web 2.0 technologies today, could impact your SOA in a very positive way. But are you ready for them? How does an SOA architect prepare for this dynamic technology?

Do you know what a mashup is and what value it brings to an enterprise? Can you distinguish between a consumer mashup and an enterprise mashup? Equally important, do you understand the difference between a mashup and popular enterprise technologies like business intelligence, data warehouses, portals, and the Enterprise Service Bus?

Mashups are not exactly new. Analysts and pundits alike have been talking about "composite applications" since the birth of the Internet. Today there are thousands of consumer-focused mashups. One popular mashup site, Programmable Web, reports that three new mashups have been registered every single day for the last two years.

Like many other buzz-laden terms (Web 2.0, for instance), the term mashup isn't subject to formal definition by any standards-setting body. One mashup expert is fond of saying that if you "ask 10 self-proclaimed mashup developers what a mashup is...you just might get 10 different answers." And there's considerable overuse and misuse of the term in software marketing. The mashup label has been used and abused by consumer and business-oriented software vendors alike in such diverse functional areas as portals, business process management, document/content management, Web scraping/clipping, and even knowledge management.

So what's a pure mashup? Mashups solve the quintessential information sharing problem: accessing and combining data from disparate internal and external data sources in ways that were not pre-imagined. Imagine connecting SAP Accounts Receivable via NetWeaver services, Oracle Human Resources via Fusion services, and some Mule-driven SOA services from a legacy database - and doing it through the global LDAP server and in a PKI infrastructure. That's a pure mashup in the context of an enterprise.

Unfortunately, most well-known mashups are much simpler: take data from one source of information and plot that data on an interactive map. But this course pattern hardly applies in the sophisticated world of the enterprise. For the purposes of this discussion, it will help to juxtapose consumer mashups from enterprise mashups.

A consumer mashup is an application that combines data from multiple public sources in the browser and organizes it through a simple browser user interface. A good example is HousingMaps (http://www.housingmaps.com), which combines Craigslist rental listings with Google Maps for a visual representation of local apartments for rent.

An enterprise mashup, also referred to as a business mashup, is an application that combines data from multiple internal and public sources and publishes the results to enterprise portals, application development tools, or as a service in an SOA cloud. Enterprise mashups must also interoperate with enterprise application technologies for security, governance, monitoring, and availability.

In the midst of the widespread popularity and adoption of cloud computing, it seems like everything is being offered “as a Service” these days: Infrastructure? Check. Platform? You bet. Software? Absolutely. Toaster? It’s only a matter of time. With service providers positioning vastly differing offerings under a generic “cloud” umbrella, it’s all too easy to get confused about what’s actually being offered. In his session at 16th Cloud Expo, Kevin Hazard, Director of Digital Content for SoftL...

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...
Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...
Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...
