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)

"Many SOA Vendors Can't Explain Their Own Product," Claims David Linthicum

Last month I wrote about vendor-driven architectures (VDA), and I had a few vendors ask me to look on the other side of the fence. In essence, to consider how vendors can better address the needs of the customer, considering the new drivers with SOA. Truth be told, I can't believe the unsophisticated approaches many vendors have when selling their product. Indeed, I'm taken aback weekly by a vendor pitch that just does not flatter their technology, perhaps even making them take a few steps back in my book, and perhaps in the opinions of their customers. Core to this is the fact... (more)

Why SOA Needs Cloud Computing - Part 1

SOA in the Cloud It's Thursday morning, you're the CEO of a large, publicly traded company, and you just called your executives into the conference room for the exciting news. The board of directors has approved the acquisition of a key competitor, and you're looking for a call-to-action to get everyone planning for the next steps. You talk to the sales executives about the integration of both sales forces in three months time, and they are excited about the new prospects. You talk to the HR director who is ready to address the change they need to make in two months. You speak ... (more)

Semantic Mapping, Ontologies, and XML Standards

When dealing with application integration, as you know by now, we are dealing with much complexity. The notion of ontologies helps the application integration architect prepare generalizations that make the problem domain more understandable. In contrast to abstraction, generalization ignores many of the details and ends up with general ideas. Therefore, when generalizing, we start with a collection of types and analyze commonalities to generalize them. Clearly, semantic heterogeneity and divergence hinders the notion of generalization, and as commonalities of two entities are r... (more)

Understanding Information Transformation

The transformation layer is the "Rosetta stone" of the system. It understands the format of all information being transmitted among the applications and translates that information on the fly, restructuring data from one message so that it makes sense to the receiving application or applications. It provides a common dictionary that contains information on how each application communicates outside itself (application externalization), as well as which bits of information have meaning to which applications. Transformation layers, such as those that process XML-based messages (e.g.,... (more)
