Another Key Difference Between REST and SOAP

It is easy to create SOAP Web Services, but difficult to consume them

A lot has been written about the difference between REST APIs and SOAP Web Services. The technical differences are well known at this stage. SOAP is heavyweight, while REST is light and mobile-friendly. However, there is another key difference which is often overlooked:

  • It is easy to create SOAP Web Services, but difficult to consume them.
  • It is difficult to create a good REST APIs, but easy to consume them.

Taking SOAP first: development platforms such as .NET made it almost too easy to create a SOAP Web Service. I remember seeing MSDN demos showing how, in a few clicks, you can take a .NET object and expose it as a Web Service, complete with WSDL. But, in those quick clicks, what had you created? You had exposed the methods of your objects as SOAP operations. But why? Is this really what you wanted to do? And while it was easy to say "Clients can just consume the WSDL to call my new Web Service", this was easier said than done. And when clients did this, it often made little sense to directly run the methods of the class.

Fast forward to the world of REST. One of the great virtues of REST is that it is so much easier to consume a REST API, compared to consuming a SOAP Web Service. In addition, it does not require parsing XML, if you prefer to directly read in JSON. However, creating a good REST API takes thought and some decisions. You should think about how you'll appropriately use the HTTP verbs, how to express versioning, and what kind of error messages you'll return. Fortunately, an API Server helps a lot here, by providing a platform for delivering APIs, to take care of aspects like security, usage quota-management, and analytics. But it still is important to take time to design your API up front.

Just last week a senior Hybris consultant shared the story of a customer engagement on which he was working. This customer had problems, serious problems. We’re talking about response times far beyond the most liberal acceptable standard. They were unable to solve the issue in their eCommerce platform – specifically Hybris. Although the eCommerce project was delivered by a system integrator / implementation partner, the vendor still gets involved when things go really wrong. After all, the vendo...
Small teams are more effective. The general agreement is that anything from 5 to 12 is the 'right' small. But of course small teams will also have 'small' throughput - relatively speaking. So if your demand is X and the throughput of a small team is X/10, you probably need 10 teams to meet that demand. But more teams also mean more effort to coordinate and align their efforts in the same direction. So, the challenge is how to harness the power of small teams and yet orchestrate multiples of them...

The initial debate is over: Any enterprise with a serious commitment to IT is migrating to the cloud. But things are not so simple. There is a complex mix of on-premises, colocated, and public-cloud deployments. In this power panel at 18th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists will look at the present state of cloud from the C-level view, and how great companies and rock star executives can use cloud computing to meet their most ambitious and disruptive business ...
The demand for organizations to expand their infrastructure to multiple IT environments like the cloud, on-premise, mobile, bring your own device (BYOD) and the Internet of Things (IoT) continues to grow. As this hybrid infrastructure increases, the challenge to monitor the security of these systems increases in volume and complexity. In his session at 18th Cloud Expo, Stephen Coty, Chief Security Evangelist at Alert Logic, will show how properly configured and managed security architecture can...
Last week I had the pleasure of speaking on a panel at Sapphire Ventures Next-Gen Tech Stack Forum in San Francisco. Obviously, I was excited to join the discussion, but as a participant the event crystallized not only where the larger software development market is relative to microservices, container technologies (like Docker), continuous integration and deployment; but also provided insight into where DevOps is heading in the coming years.
Admittedly, two years ago I was a bulk contributor to the DevOps noise with conversations rooted in the movement around culture, principles, and goals. And while all of these elements of DevOps environments are important, I’ve found that the biggest challenge now is a lack of understanding as to why DevOps is beneficial. It’s getting the wheels going, or just taking the next step. The best way to start on the road to change is to take a look at the companies that have already made great headway ...

When I talk about driving innovation with self-organizing teams, I emphasize that such self-organization includes expecting the participants to organize their own teams, give themselves their own goals, and determine for themselves how to measure their success. In contrast, the definition of skunkworks points out that members of such teams are “usually specially selected.” Good thing he added the word usually – because specially selecting such teams throws a wrench in the entire works, limiting...

While there has been much ado about interoperability, there are still no real solutions, same as last year and the year before that. The large EHR vendors who continue to dominate the market still maintain that interoperability is all but solved, still can't connect EHRs across the continuum causing frustration by providers and a disservice to patients. The ONC pays lip service to the problem, but that is about it. It is time for the healthcare industry to consider alternatives like middleware w...
