4 Answers. As the terms imply a Service Oriented Architecture is oriented at services, and a Resource Oriented Architecture is oriented at resources. In general differences between two things A and B are often best explained by defining the essence of A and B.

Difference Between API and Web Service. API and Web service serve as a means of communication. The only difference is that a Web service facilitates interaction between two machines over a network. An API acts as an interface between two different applications so that they can communicate with each other.

Restful Web Services is a stateless client-server architecture where web services are resources and can be identified by their URIs. REST Client applications can use HTTP GET/POST methods to invoke Restful web services. ... When compared to SOAP web services, these are lightweight and doesn't follow any standard.

AJAX is a set of (typically) client-sided web development techniques, while REST is an architecture style for sending and handling HTTP requests. So you can use AJAX to send RESTful requests. A REST API is typically not implemented using AJAX, but can be accessed by an AJAX client.

1 Answer. Webservice specifically refers to a SOAP implementation, and HTTP simply refers to any service that uses the HTTP protocol, the most popular being REST and SOAP. From there, they differ in how they are used. REST typically uses JSON, while SOAP uses XML with certain required formats.

RPC-based APIs are great for actions (that is, procedures or commands). REST-based APIs are great for modeling your domain (that is, resources or entities), making CRUD (create, read, update, delete) available for all of your data. REST is not only CRUD, but things are done through mainly CRUD-based operations.

Servlets are API which is simple and provides capabilities to write server side components. Web Service uses ServletContainer class which is again a Servlet class, which handles the request in clean and structured way. The REST stands for REpresentational STateless Protocol. Here the request won't store any data.

Basic and primary difference is, ASP.NET web service is designed to exchange SOAP messages over HTTP only while WCF Service can exchange message using any format (SOAP is default) over any transport protocol i.e. HTTP, TCP, MSMQ or NamedPipes etc. ... Web Services use XmlSerializer but WCF uses DataContractSerializer.

A Web service is a "call" to an application, a system, or a hub that asks a question, like: "Does this customer already exist?" By definition, a Web service uses the web to communicate its business question. SOA, on the other hand, is the architectural framework that enables a series of those Web services to occur.

SOAP API, on the other hand, has an official standard because it is a protocol. REST APIs uses multiple standards like HTTP, JSON, URL, and XML while SOAP APIs is largely based on HTTP and XML. ... SOAP API defines too many standards, and its implementer implements the things in a standard way only.

Wikipedia says "The Web Services Description Language is an XML-based language that provides a model for describing Web services". ... WSDL/SOAP uses multiple transport protocols, REST relies on only HTTP. Therefore WSDL/SOAP can be used like a RESTful way, however simple requests can be overly complicated/heavy weighted.

As opposed to SOAP, REST is not a protocol but an architectural style. ... It allows different messaging formats, such as HTML, JSON, XML, and plain text, while SOAP only allows XML. REST is also a more lightweight architecture, so RESTful web services have a better performance.

That's primarily the difference: SaaS offerings are applications that are fully formed end-user applications. Cloud Computing is computing infrastructure and services that you can rent. If you are in business, you will want to focus more on SaaS than cloud computing, unless your company develops software for a living.

As per difference in both, the applications come where, how to access the resources. In Client-Server, once the connection is made it will be in the state on connected, whereas in case of web testing HTTP protocol is stateless, then there comes logic of cookies, which is not in Client-Server.

Web Applications are meant for their human interactions through views whereas Web API aka Web Services are meant for system-to-system interactions (information exchange programatically ). They exchange data.

In an asynchronous interaction, a client sends a request to a service and waits until the service replies. ... Note the difference between this and responding from a synchronous BPEL process: a synchronous BPEL process uses a reply activity to respond to the client and an asynchronous service uses an invoke activity.

The difference between a process is that it manifests itself in an application that you directly interact with, like your web browser or your IM client. A service doesn't abide by the same rules, and it generally runs outside of your direct interaction — always-on antiviruses, your system clock, things like that.
