The principles behind Service-Oriented Architectures (SOA) were established long before the Internet became a force, and certainly before the appearance of Cloud infrastructure. Although many people consider SOA as well as the Cloud to be about ways of building, deploying and managing applications, these technologies and methodologies are also important in making "big data" useful and manageable. Indeed, SOA and Cloud are increasingly becoming so intertwined as to cause major confusion in the marketplace. Let's be clear - there's SOA, and there's Cloud and there's the intersection of SOA and Cloud. That intersection is a very exciting place to be I remember having discussions a couple of decades ago on technologies like CICS, which embodied many of the principals behind SOA - and I'm sure there are technologies (and methodologies) older than that which similarly embo...

Software Best Practices: Use Cases Are for Everyone

What Are Use Cases and Who Uses Them? Use Cases are NOT just for requirements gathering by project managers. They're far too useful to be relegated to that niche. For those not familiar with use cases, you can look up various confusing definitions which make reference to UML diagrams and such - but generally speaking in the world of software design, they describe how a person interacts with a piece of software. For example, a use case for Amazon.com might describe how a user searches for a book title.  Ultimately, use cases when collected together describe how software is used, wh... (more)

Netflix Shocker: Confidence Crisis

Boomberg's Cliff Edwards reported the facts well: Netflix Inc. (NFLX) dropped the most in seven years after the video-rental service said it lost 800,000 U.S. subscribers in the third quarter, more than expected, and predicted more cancellations over a price increase. Netflix plunged 37 percent to $75.28 at 9:39 a.m. New York time, for the biggest intraday decline since October 2004. The stock closed at an all-time high of $298.73 on July 13, according to Bloomberg data. The outlook suggests Netflix has been unable to contain a subscriber revolt over a price increase and aborted p... (more)

Software Quality Best Practices: Healthy Software

Consider the following scenario-typical in many application development organizations. A major new release of an application has just gone into production. Although the development and QA teams endured many late nights of coding and testing, and consumed large quantities of delivered pizza, the project missed its ship date. Still, customers are happy with the product and are giving positive feedback. By many definitions, the team has produced a quality product. Then, a new, large business opportunity requires the rapid implementation of a significant new feature in the product. ... (more)

Steve Jobs: Software Hero

I’ve been using Steve Jobs and Apple as examples in my software blog dedicated to the creation of Great Software. Although Steve Jobs is thought of as being the Mac/iPhone/iPad/iPod guy, he’s also a software hero. At least he’s one of my software heroes. Steve Jobs’ Apple doesn’t just build products. They understand the market and the consumers better than anyone else. And then they create something that defines and totally owns that market. Their deep understanding of the needs, wants and priorities of the consumer and their “make no compromises” approach allows them to do this... (more)
