The IT industry is positioned to experience major technology shifts within the next few years as a result of the rise of cloud adoption. According to Gartner, more than $1 trillion in IT spending will be affected by the shift to the cloud by 2020 - making cloud computing "one of the most disruptive forces of IT spending since the early days of the digital age." As enterprises prepare for, or continue to run on, the cloud, it is important for them to have a strong grasp of the cloud adoption process and the requirements for ongoing management of cloud environments. Here are five major trends that will shake up the industry in 2017. 1. Major acquisitions The pressures of cloud computing are becoming increasingly prevalent. As enterprises fight to stay ahead of the competition, many will choose to pursue acquisitions to both bolster their existing capabilities and fill ... (more)

SOA and User Interfaces

What is unique about an SOA is that it's as much of a strategy as a set of technologies, and it's really more of a journey than a destination. Moreover, it's a notion that is dependent upon specific technologies or standards, such as Web services and interface technology, but really requires many different types of technologies and standards for a complete SOA. The types of technologies you employ are dependent upon your requirement. Let's be a bit clearer as to where user interfaces fit into this SOA mix by providing core reference architecture, or, the basics of SOA. Figure 1 ... (more)

Real-World AJAX

So, what do AJAX and SOA have in common? The answer: Everything. Is AJAX an enterprise technology? The answer: Absolutely. As we move to next-generation enterprise architectures using newer notions such as Service Oriented Architecture (SOA), there's a need for a dynamic Web interface that can layer over services and provide more value to the enterprise. Moreover, the enterprise in general can benefit from the advantages of AJAX; it's just a matter of making enterprise developers as well as the SOA architects aware of AJAX. AJAX is becoming the standard dynamic interface for the W... (more)

SOA World - Approaching SOA Testing

So, does testing change with SOA? You bet it does. Unless you're willing to act now, you may find yourself behind the curve as SOA becomes systemic to all that is enterprise architecture, and we add more complexity to get to an agile and reusable state. If you're willing to take the risk, the return on your SOA investment will come back three fold...that is, if it is a well-tested SOA. Untested SOA could cost you millions. Truth be told, testing SOAs is a complex, disturbed computing problem. You have to learn how to isolate, check, and integrate, assuring that things work at t... (more)

SOA - Loosely Coupled...What?

With the advent of Web services and SOA, we've been seeking to create architectures and systems that are more loosely coupled. Loosely coupled systems provide many advantages including support for late or dynamically binding to other components while running, and can mediate the difference in the component's structure, security model, protocols, and semantics, thus abstracting volatility. This is in contrast to compile-time or runtime binding, which requires that you bind the components at compile time or runtime (synchronous calls), respectively, and also requires that changes ...
