Keep Your SOA and BPM Initiatives Separate

The entanglement of SOA and BPM into a single effort is fraught with problems and failure

Not to beat the dead horse, but during a discussion the other day with a fellow SOA cohort, I came to a realization for the reason SOA & BPM get inextricably tied together in some individual’s thoughts. I’ve written and blogged before on how SOA & BPM have very different goals. SOA is about application rationalization via a service metaphor and BPM is about business process analysis and optimization. The fact that they are discussed in the same breath leads one to believe that they are inherently related, when in fact they are not.

That said, as one performs a top-down analysis of their business as part of a BPM initiative, they are going to discover they need a framework to assist in implementing new business processes that cut across departmental and other organizational boundaries. Clearly, one of the greatest areas for improvement within in an organization is across these organizational boundaries because process improvement tended to be an intra-departmental exercise. When the process needed to cross an organizational boundary, the political, geographic, technological, etc. hurdles led to inefficient crossings.

Historically, SOA and BPM rose in popularity at or around the same time. SOA, led primarily by technological practitioners, responded to the needs of BPM practitioners for a framework to capture and implement newly-designed and efficient cross-organizational business processes with technology. However, for BPM, technology is the least of the problems. Indeed, BPM’s biggest issues are political and geographic in nature. A process that needs to cross continents or rely on participation of a department that is resistant to change pose a far greater problem to process optimization than not having a web service available to invoke.

Still, there is seems to be a natural gravitation toward SOA as providing the necessary framework to capture and implement new cross-organizational business processes. Most likely it is the service façade that allows various business functions to be exposed as technological assets accessible over common Internet protocols. After all, what better way to create a business process that crosses organizational boundaries than tapping directly into the data and systems that support those sub-organizational areas?

However, it’s important to note that SOA should not be viewed as the nail for BPM’s hammer, as is all too popular a notion today. It is not an SOA if you decided to wrap a few legacy systems with web services so that you could easily build out an automated business process. That is just part of your BPMS effort.

This entanglement of SOA and BPM into a single effort is fraught with problems and failure. Each initiative should be undertaken separately and with definitive goals that do not list each other as one of the outcomes. If as part of the rationalization that SOA provides, there happens to be some services exposed that simplify the implementation of a particular business process, then that would certainly be a slam-dunk. However, SOA and BPM each have their own metrics of success and their own barriers to success. Combining them into one, well, the words “boiling the ocean” comes to mind.

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.
The margins of cloud products like virtual machines are still in the 50% range. In essence, price drops are going to be a regular feature for the foreseeable future. This begets the question - are hosted solutions becoming irrelevant today? Boston-based market research firm, 451 Research, has been publishing their ‘Cloud Price Index' for a few years now. The quarterly study looks into the pricing of various offerings in the cloud market to understand the shifting dynamics in the public, privat...

Managing mission-critical SAP systems and landscapes has never been easy. Add public cloud with its myriad of powerful cloud native services and this may not change any time soon. Public cloud offers exciting new possibilities for enterprise workloads. But to make use of these possibilities and capabilities, IT teams need to re-think everything they have done before. Otherwise, they will just end up using public cloud as a hosting platform for their workloads, aka known as “lift and shift.”
There's a lot to gain from cloud computing, but success requires a thoughtful and enterprise focused approach. Cloud computing decouples data and information from the infrastructure on which it lies. A process that is a LOT more involved than dragging some folders from your desktop to a shared drive. Cloud computing as a mission transformation activity, not a technological one. As an organization moves from local information hosting to the cloud, one of the most important challenges is addressi...
The reality of data ubiquity is here—data is buried in operational statistics, machine logs, stacks of overflowing tickets and customer details, among other things. How can any user get valuable information amid this rapid influx of data? Imagine a situation where your firm’s revenue takes a hit owing to an unexpected failure in some business process. It would be a nightmare for IT admins to sift through the interminable piles of data to deduce exactly why and where the problem occurred. To sav...
Hybrid IT is today’s reality, and while its implementation may seem daunting at times, more and more organizations are migrating to the cloud. In fact, according to SolarWinds 2017 IT Trends Index: Portrait of a Hybrid IT Organization 95 percent of organizations have migrated crucial applications to the cloud in the past year. As such, it’s in every IT professional’s best interest to know what to expect.
Both SaaS vendors and SaaS buyers are going “all-in” to hyperscale IaaS platforms such as AWS, which is disrupting the SaaS value proposition. Why should the enterprise SaaS consumer pay for the SaaS service if their data is resident in adjacent AWS S3 buckets? If both SaaS sellers and buyers are using the same cloud tools, automation and pay-per-transaction model offered by IaaS platforms, then why not host the “shrink-wrapped” software in the customers’ cloud? Further, serverless computing, cl...
In the decade following his article, cloud computing further cemented Carr’s perspective. Compute, storage, and network resources have become simple utilities, available at the proverbial turn of the faucet. The value they provide is immense, but the cloud playing field is amazingly level. Carr’s quote above presaged the cloud to a T. Today, however, we’re in the digital era. Mark Andreesen’s ‘software is eating the world’ prognostication is coming to pass, as enterprises realize they must be...
A common misconception about the cloud is that one size fits all. Companies expecting to run all of their operations using one cloud solution or service must realize that doing so is akin to forcing the totality of their business functionality into a straightjacket. Unlocking the full potential of the cloud means embracing the multi-cloud future where businesses use their own cloud, and/or clouds from different vendors, to support separate functions or product groups. There is no single cloud so...
In 2014, Amazon announced a new form of compute called Lambda. We didn't know it at the time, but this represented a fundamental shift in what we expect from cloud computing. Now, all of the major cloud computing vendors want to take part in this disruptive technology. In his session at 20th Cloud Expo, Doug Vanderweide, an instructor at Linux Academy, discussed why major players like AWS, Microsoft Azure, IBM Bluemix, and Google Cloud Platform are all trying to sidestep VMs and containers wit...
Companies have always been concerned that traditional enterprise software is slow and complex to install, often disrupting critical and time-sensitive operations during roll-out. With the growing need to integrate new digital technologies into the enterprise to transform business processes, this concern has become even more pressing. A 2016 Panorama Consulting Solutions study revealed that enterprise resource planning (ERP) projects took an average of 21 months to install, with 57 percent of th...
