Simple Object Access Protocol – SOAP: Methods, Concepts and Examples

SOAP imageSOAP (Simple Object Access Protocol) is a protocol for exchanging XML-based messages over computer networks, normally using HTTP/HTTPS. SOAP forms the foundation layer of the web services protocol stack providing a basic messaging framework upon which abstract layers can be built.

There are several different types of messaging patterns in SOAP, but by far the most common is the Remote Procedure Call (RPC) pattern, in which one network node (the client) sends a request message to another node (the server) and the server immediately sends a response message to the client. SOAP is the successor of XML-RPC, though it borrows its transport and interaction neutrality and the envelope/header/body from elsewhere, probably from WDDX.

REST (Representational State Transfer) and RESTful web services: Methods, Concepts and Examples

REST vs SOA; the Lego analogyRepresentational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. As such, it is not strictly only a method of building what are sometimes called “web services.” The terms “representational state transfer” and “REST” were introduced in 2000 in the doctoral dissertation of Roy Fielding,[1] one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification. The terms have since come into widespread use in the networking community.

REST strictly refers to a collection of network architecture principles which outline how resources are defined and addressed. The term is often used in a looser sense to describe any simple interface which transmits domain-specific data over HTTP without an additional messaging layer such as SOAP or session tracking via HTTP cookies. These two meanings can conflict as well as overlap. It is possible to design any large software system in accordance with Fielding’s REST architectural style without using HTTP and without interacting with the World Wide Web.[citation needed] It is also possible to design simple XML+HTTP interfaces which do not conform to REST principles, and instead follow a model of remote procedure call. The difference between the uses of the term “REST” therefore causes some confusion in technical discussions.

Amazon Web Services: Overview and Example with Java and PHP

Until 1 hour ago I had same problems with Wordpress, image and other functionality didn’t work. After done all the means in my power and ability, I decided to contact wordpress. Wordpress problem derived from Amazon Web Services dependencies! What’s that?

The Amazon Web Services (AWS) are a collection of remote computing services (also called web services) offered over the Internet by

Launched in July 2002, Amazon Web Services provide online services for other web sites or client-side applications. Most of these services are not exposed directly to end users, but instead offer functionality that other developers can use. In June 2007, Amazon claimed that more than 330,000 developers had signed up to use Amazon Web Services.
