Earlier I computed various statistical estimates like mean or variance-covariance matrix using Intel® Summary Statistics Library. In those cases I knew for sure that my datasets did not contain “bad” observations (points which do not belong to the distribution which I observed) or outliers. However, in some cases we need to deal with datasets which are contaminated with outliers.
In many conversations I participate in regarding Service Oriented Architecture (SOA), part of the conversation oftens leads to "....how best can I incorporate my mainframe in the SOA architecture...". There are a number of mainframe SOA-enabling options, and in this post I will share my opinion on the application of a short-list of tried and true approaches.
Integrating the hot, new SaaS application into a company can often be a challenging undertaking. The SaaS application was acquired for a pressing departmental need, yet manually re-inputting and syncing key data like employee, vendor or supplier master directories is not practical. Manually coordinating a sale by the customer saying "yes" with a win recorded in the sales force automation tool yet hand crafting delivery instructions in the order module of the ERP is not really a sustainable business proc
This might sound odd to some of you reading this, but I am regularly asked the following question ... "What is the difference between SOA and SaaS?".
Given the acronym soup of the IT industry I am not surprised to get that question and expect to for some time to come. The simple answer is that:
- Service Oriented Architecture (SOA) is a means of designing and building software. It is a manufacturing model.
In my last several posts I have been sharing the concepts of a new product category I have been referring to as a SOA "soft appliance". Those posts have covered the origin of the idea, features, benefits and how is it similar to and different from other types of service-enabling infrastructure.
Going forward for a while, I plan on posting on the deployment architectures and usages of a SOA "soft appliance" platform like Intel SOA Expressway.
In the last blog I wrote about the similarities and differences between a SOA "soft appliance" like Intel SOA Expressway and an ESB-based product. Two key questions often arise out of that discussion: (1) Why do I need a SOA appliance if I already have an ESB, and (2) Why is a "soft appliance" better than an easy-to-deploy, secure and high-performance hardware appliance?
