If you’re wondering why some web services based in India or the Middle East hasn’t responded to your queries in a long time, don’t fret too much. It’s not that there was a sudden political censorship nor terrorist activity went on there. They are unable to connect to the Internet for a long time since the undersea cables in the Mediterranean got damaged.
There was disruption to 70% of the nationwide network in Egypt, and India suffered up to 60% disruption.
UK firms such as British Airways have told the BBC that call centres have been affected by the outage.
Industry experts said it could take up to one week to repair the damaged cables and resume full service.
International telephone calls, which have also been affected, are being rerouted to work around the problem.
Not to worry though as repairs are underway to return Internet connection to the affected countries in that region. The estimated time of service returning is within the week.
Many businesses have jumped onto the SOA bandwagon and with new technology and thinking, comes new problems that can have a negating effect compounding existing problems you were supposedly to solve. SOA might be fine for the services sector and other fields but for IT has been quite difficult for a survey by Business week has some 32 % of all companies who have jumped the bandwagon saying they are not fully meeting their set expectations. While a good 58% of all of those who implemented SOA say that they have indeed reached goals yet the high failures are quite alarming for it may need another revolution or a change of approach for the dream of a fully SOA driven business to take place.
RESTful is an attempt to emulate HTTP and the other protocols with the use of stateful resources rather than on messages or operations. Support for the said technology set is still quite weak such as in SDK�s or Software Development Kits which developers use to develop projects/programs for implementation on the web. Critics are truly after the technology set calling them too complex and biased towards large software vendors. The said technology is quite proprietary which goes against current trends of making these types of technologies more open sourced in hopes of bringing costs down. More complex projects that operate similar to the structure of RESTful are Cobra and Dcom along with XML-RPC are in the works but are still meeting opposition of many web gurus.
New technology has led to development of more robust messaging allowing confidentiality, integrity and authentication. Innovations and developments from companies like IBM have led to better implementation using opaque encryption keys to address many security issues related to the said framework in conjunction with other Web Service Protocols. Coined or called WS-Security the technology provides a set of mechanisms to help developers of web services to secure SOAP messaging exchanges through enhances security and handling. It also provides a general-purpose association of security ring tokens with messages but without specific type of security token which is defined by the developer.

Well, it means your company won’t need to get the most expensive computers on the planet to run applications that have resources and information stored over several locations giving each and every computer the ability to share secure information quickly and safer. In the past, branches say of banks had to do processing at the end of the day to send all data collected during the day for processing at the head offices mainframes. Now we can have the data processed in-house then send the processed data to the mainframe and other branches who do processing at the same time returning all relevant information to the respective branches for updating of customer�s information which they in turn can access through the branch server. Confused, less cost per gigabyte of data processed, less storage space needed for data, less powerful computers (which is one of the most expensive investment in most firms) and less manpower needed to manually transmit data to and from branches and head office for all processing is now done on-line in real time as it happens.
Is the most memory efficient random access parser in the world which is a suite of XML processing technologies defined as Virtual Token Descriptor. It can be viewed as any of the following; an XML Parser that is document centered, a file format that enhances text XML, an XML content modifier, an XML assembler/splitter/slicer, an eraser/editor or a way of hard-wiring XML technology on a chip. Better suited to Service Oriented Applications using java to which only minor modifications are needed. It eliminates the need for repetitive processing reducing the need for high power computers for distributed processing.
Web Services Description Language, provides a basic model of web services with it defining services as a collection of endpoints on the network. It employs XML based formats for use. It is mostly combined with SOAP and the XML schema where in the WSDL file is embedded with XML schema which is then used by the client through SOAP to do the actual work of calling the function listed in the WSDL file.
Xlang an extension that was developed for WSDL to describe an extension of a business process thus making it faster than the original format.
The days of software installation and re-installation in case some files get corrupted are gone and in are the next generation of software that are web-based. The internet’s infusion into all the corners of the world is the culprit for it allows users from all over the world to share and send information to one another. The problem was the software the millions upon millions of individual computers had installed in them which are sometimes non interoperable. A computer with word 97 cannot open a document created in office 2007 and other similar cases. Throw in the advent of the latest Mac and all the other software installed onto them plus the rise of Open sourced systems based on Linux and you have a ton of software that just won’t cooperate with each other. Distributed installations had people left to their own accord on whether they had all the necessary patches and updates installed. Lack of vigilance when it comes to keeping all files up to date leaves them very much vulnerable to attack form fast propagating malware, many of which can change signatures from computer to computer, making detection difficult. Installing the software at a central location and offering it to all the users of the internet makes everything easier, one machine to update, install on and maintain eliminating the need for bridging software which was usually needed to get documents created on a Mac red and edited on Linux and Windows. No more stored information regarding format conversions, and other necessary files just one central core to the whole web.
The move to accommodate all and we do mean all aspects of the diverse computing environment may be too much for the industry to handle. The flexibility it promises is outweighed by the resulting size of changes they say are necessary for the system to work. Detractors are crying foul in what they call is another large scale fiasco by big businesses who by promoting and using them drags the rest of us with them just so you can continue to use them. This might be a classic case similar to the hardware and software developer fiascos where chip makers release or delay their release of newer technology till big developers get around to using their computers and the trend works the other way round too. So the future of XML is looking bumpy as the debate goes on in the never ending quest to attain a perfectly stable yet flexible platform which could be the face of the internet in the years to come.
Web service defenders have to answer to detractors who say that the XML system they are developing has gotten just a bit too complicated and too vague that traditional methods might be better. That is the ongoing debate for as the XML standard is still in development and changes are being done to accommodate all platforms of implementation; many question its ability to deliver. Many have benefited from Web Services mostly in the banking and services sector but the IT industry who is promoting the new shift has been getting heat, burned by their desire for rapid change. SOA’s have been failing considerably and XML is expected to follow suit for even before they enter mainstream implementation problems have already surfaced.
