This article provides a brief introduction to the two styles of web-services interaction and details the benefits and challenges associated with each one.
Cloud computing 21 concept of wsdl modelingVaibhav Khanna
WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint.

The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint.
A Web service (WS*-) is a software system designed to support interoperable machine-to-machine
interaction over a network (WSDL) i.e between a client and a service. It has an interface described in a
machine-processable format . Other systems interact with the Web service in a manner prescribed by its
description using SOAP messages which is a protocol define by world wide web consortium, typically
conveyed using HTTP with an XML serialization in conjunction with other Web-related standards. Windows
Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF,
you can send data as asynchronous messages from one service endpoint to another. A service endpoint can
be part of a continuously available service hosted by IIS, or it can be a service hosted in an application like
an .exe file. An endpoint can be a client of a service that requests data from a service endpoint. The messages
can be as simple as a single character or word sent as XML document, or as complex as a stream of binary
data. In this paper ,We gave the Adavantages that are Available by using wcf ,instead of webservices and
other.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

2. Basic Concept of WEB Services
6
• A Web service typically carries comprehensive business
logic, can be searched through the Web, and has to be
accessed through the Internet or Intranet environment.
Above all, a Web service is published in a standard language
and accessed through a standard protocol.
3. Basic Concept of WEB Services
• A Web service is a programmable module with standard
interface descriptions that provide universal accessibility
through standard communication protocols. The functions
offered by Web services can be implemented in different
programming languages on different platforms.
7
4. Basic Concept of WEB Services
The paradigm of Web Services is changing the Internet
from a repository of Web Content into a repository of
Services in Three Significant Ways:
1. First, by means of each organization exposing its business
applications as services on the Internet and making them
accessible via standard programmatic interfaces, this model
of Web services offers a promising way to facilitate
Business-to-Business B2B) collaboration within and across
enterprise boundaries
8
5. Basic Concept of Web Services
2. Second, the Web services technology provides a uniform
and loosely coupled integration framework to increase
cross-language and cross-platform interoperability for
distributed computing and resource sharing over the
Internet, inside or outside of firewall.
3. Third, the paradigm of Web services opens a new cost-
effective way of engineering software to quickly develop
and deploy Web applications, by dynamically integrating
other independently published Web service components
into new business processes.
9
6. Modeling a Web Service
The Web Services Description Language (WSDL) has
become an ad hoc industry standard for describing a Web
service
Simple Object Access Protocol (SOAP) has become an ad
hoc industry standard for accessing a Web service.
WSDL Version 2 and SOAP Version 1.2 are endorsed by the
World Wide Web Consortium (W3C).
10
7. Basic Concept of WSDL Modeling
WSDL is “an XML format for describing network services as a
set of endpoints operating on messages containing either
document-oriented or procedure-oriented information”
(http://www.wsdl.org).
It is created to define the public interface of a Web service,
including its functionalities and how to invoke them.
11
8. Basic Concept of WSDL Modeling
A WSDL document defines the protocol bindings and
message formats required to interact with the Web services
listed in its directory.
The supported operations and messages are described
abstractly, associated with a concrete network protocol and
message format.
12
9. WSDL and SOAP (Interface and
Protocol)
WSDL provides a notation to answer the following three
questions:
What is the service about?
Where does it reside?
How can it be invoked? (i.e., what, where, and how)
13
10. WSDL and SOAP (Interface and
Protocol)
WSDL is often used in combination with SOAP and XML
schema to define a Web service over the Internet.
A client program reads a WSDL document to understand
what it can do; data types used are embedded in the
WSDL file in the form of XML schema.
The client then uses SOAP to actually invoke the
functions listed in the WSDL document.
14
11. Basic Elements of WSDL
A Web service is defined as a set of
ports, each publishing a collection of
port types that bind to network
addresses using a common binding
mechanism.
Every port type is a published
operation that is accessible through
messages.
Messages are in turn categorized into
input messages containing incoming
data arguments and output messages
containing results.
Each message consists of data
elements; every data element must
belong to a data type, either an XML
Schema Definition (XSD) simple type
or a XSD complex type.
15
12. Sample Segment of a WSDL Document
The tag portType defines “productPrice” as
the name of a port, and “getPrice” as the
name of an operation.
The “getPrice” operation defines an input
message named “getPriceRequest” and an
output message “getPriceResponse.”
The tag message defines the parameters
and associated data types of the input
message and the output message.
Compared to traditional programming
language, “productPrice” maps to a
function library, “getPrice” maps to a
function with “getPriceRequest” as the
input parameters and “getPriceResponse”
as the return parameters.
<message name="getPriceRequest">
<part name="productid"
type="xs:string"/></message>
<message name="getPriceResponse">
<part name="value"
type="xs:string"/></message>
<portType name="productPrice">
<operation name="getPrice">
<input
message="getPriceRequest"/>
<output
message="getPriceResponse"/>
</operation>
</portType>
16
13. Operation Types Defined in WSDL
WSDL defines four types of operations: one-way, request-
response, solicit response, and notification.
The one-way operation receives a message but does not
return a response message.
The request-response operation receives a request and
returns a response.
The solicit-response operation sends a request for a
response.
The notification operation sends a message but does not
wait for a response.
The request-response type is the most frequently used
operation type.
17
14. Web Services Communication
Protocol: SOAP
SOAP is a simple and lightweight protocol for exchanging
structured and typed information among Web services.
In the core of the Web services model, SOAP acts as the
messaging protocol for transport with binding to existing
Internet protocols, such as Hypertext Transfer Protocol
(HTTP) and Simple Mail Transfer Protocol (SMTP) as
underlying communication protocols.
Defining a uniform way of passing XML-encoded data, SOAP
also enables a way of conducting Remote Procedure Calls
(RPCs) binding with HTTP.
18
15. Web Services Communication
Protocol: SOAP (Cont’d)
In short, SOAP provides a way to communicate between
applications running on different operating systems, with
different technologies, and programming languages.
SOAP is endorsed by W3C and key industry vendors such as
Sun Microsystems, IBM, Microsoft, etc.
Detailed information about SOAP can be found at the W3C
Web site at http://www.w3c.org/TR/SOAP.
19
17. Binding of WSDL to SOAP
A WSDL document defines how to access a service
operation using the element binding: the message format
and protocol details for each port.
The binding tag has two attributes: the name attribute and
the type attribute.
The name attribute defines the name of the binding, and
the type attribute points to the port for the binding, in
this case it is the “productPrice” port.
21
18. Binding of WSDL to SOAP
The tag soap:binding has two attributes: the style
attribute and the transport attribute. The style attribute
can be either “ RPC (Remote Procedure Call)” or
“document.”
The transport attribute defines the SOAP protocol to use,
in this example it is “HTTP.” The tag operation defines
each operation that the port exposes. For each
operation, the corresponding SOAP action needs to be
defined. One needs to specify how the input and output
messages are encoded.
22
20. Publishing a Web Service in Registry
Universal Description, Discovery, and Integration (UDDI) is
an ad hoc industry standard that provides a “meta service”
for publishing and locating Web services by enabling robust
queries against rich metadata.
The UDDI working group includes leading technology
vendors, such as IBM, HP, and Microsoft. Detailed
information about UDDI can be found at its official Web site
at http://www.uddi.org/.
