MapReduce moving into enterprise architecture world

MapReduce is a Google-inspired program looking to help enterprises clean up their databases and put them into the clouds. SearchSOA.com recently took a look at it here. This was a program originated by Google programmers who wrote programs for parallel situations, so data use was properly transferred from program to program. It also analyzes both structured and unstructured data.

Rich Seeley of SOA Situations can be useful in three situations:

- Text tokenization, indexing, and search

- Creation of other kinds of data structures (e.g., graphs)

- Data mining and machine learning.

What is WOA

This article from cnetnews.com states: Web-oriented architecture (WOA), a descriptive term for a subset of service- oriented architecture (SOA), has recently arisen as the next buzz-phrase to help further confuse the IT architect. So what is it? The article explains that WOA is an implementation of SOA that utilizes representational state transfer resources that permit data and services to be utilized through a uniform resource identifier. Another explanation comes from Nick Gall from Gartner:

WOA is an architectural style that is a substyle of SOA based on the architecture of the www with the following additional constraints: globally linked, decentralized, and uniform intermediary processing of application state via self-describing messages.

Growth of SOA in India

Business Standard mentioned today, in this article, that India is expected to have the “fastest growing SOA market in the Asia-Pacific region”. Springboard Research has predicted that this market will have a compound annual growth rate of 49% from 2006 to 2009. Many organizations are already starting to seize this opportunity. Intelligroup, one company interested in this growth rate, believes that 20% of the “larger SAP customer in India” will be adopting SOA within the year. Liladhar Bagad, practice head of Intelligroup, released this statement as a means to explain this growth:

“As organisations become more global, SOA will become an integral part of their strategy. It is aimed at lowering the total cost of ownership, simplifying integration and customisation. Organisations are increasingly embracing SOA as a means to access and distribute information in real time”

It is cautioned, however, that organizations need to be aware of disappointment that some companies may announce. As Chandika Mendi, director and head of Virtusa Corporation, explained

“The reason for the disappointment will be due to taking a much narrowed approach while defining SOA, which could lead to failure of implementations. Also, the initial investment in SOA is high and will reap benefits slowly as the entire enterprise moves to it, which is a fairly long journey,”

Adopting SOA: More than just getting the software

In a recent article at CIO, Ty Anderson discuses how adopting SOA into the business is like buying a total home gym. Buying it doesn’t get the job done, it’s important to use the purchase continually in order to get the benefits the software can offer.

-- It’s important to audit existing applications. See what the processes are for your current business processes. Know what you’ve got so you can start in the right place.

-- Make the services as simple as possible

-- Work with your SOA tools every day. You’ve got to continually work towards the adoption, day in and day out to find out how the software truly works.

-- Keep working – Now that you’ve got SOA, it’s important to keep it current. Learn what’s new in the software and implement additional tools that are beneficial to your company.

And throughout the whole process, have someone there to keep you going in the right direction. A mentor can help you achieve your goals and keep you working towards the benefits of SOA.
