About Judith Hurwitz
My name is Judith Hurwitz. I have been an infrastructure and enterprise software industry analyst and strategy consultant for several decades. The central focus of my writings is around the cloud. I take a pragmatic and holistic view of the cloud. So I apply my knowledge in service oriented architectures, service management, distributed architectures, systems and applications management, security, information management, collaborative computing, social networking to the cloud. My philosophy is that you simply can’t wall off components of technology if you really want to realistically understand the business value of software. So, I like to have a dialog with you — about how I see the market today and tomorrow I am pragmatic, skeptical, and curious. I have been writing long and short Dummies books for the last two years including the newly published Cloud Computing for Dummies, Service Oriented Architectures for Dummies, Information on Demand for Dummies, Service Management for Dummies (2009), and Collaboration for Dummies.

Hi
I am impressed with your work in SOA and related filed and wanted to know from your expert experience that if I have to transform a Java application which is currently running on client server mode (RMI communication between client and server) to SOA based architecture where at server side coarse grained services will be there and SOAP will be the communication protocol. Client still be Java Swing application as it is running right now. If I have a client side library which is talking to server on behalf of client that needs to be removed and any locally running logic needs to be maintained at server side coarse grained objects. Another thing I want to do with my system is that I want to make it more cohesive by splitting it in to several sub systems. Some core part of this system will remain as this system, other (say for an example 3 ) sub systems will be created from existing system.
Now If I have only total lines of all code known how can I estimate effort and schedule for this kind of exercise?
If you have worked on any such type of Java application migration to SOA based architecture reusing as much as possible from existing application (almost all) how much effort is required as percentage of existing code size.
Take an assumption that there are total 1500000 lines of code in which 900000 are Java lines. Remaining are SQL code, JSP, HTML, etc.
Cloud Computing has a place like SAAS, Managed Service etc and I don’t believe it is the ubiquitous solution for all. It also isn’t an entirely new concept, but rather a modified version of Bureau Service, Utility Computing …etc. All these provided computing services at a cost depending on the solutions required.
In addition, the real economics of Could Computing is not well understood and currently there is a fair bit of Hype and emotions attached to it.
To add to this, a lot of issues that are not easy to sort out for example, licenses, data security, intellectual property and the depended connectivity contracts and Service levels…etc could present some interesting challenges.
But, what bugs me most is the “Real economics of Cloud Computing” from the major infrastructure Vendors perspective as this would most definitely cannibalise their market, and what would drive them to support this as the ubiquitous solution?
I’m not against Cloud Computing but feel that some caution is required before we “throw the baby out with the bath water”
Thanks for your coverage in the space of cloud computing. I’m an ERP application guy, so you’re work is literally laying the groundwork for me.
