RPC is basically a method call interface that many developers understand. The basic unit of these types of services is the WSDL operation. It is not loosely coupled, though, it is used by mapping services directly to specific method calls. THis is not the easiest one to understand, though, and not very reliable.
SOA, or service oriented architecture is where the message is the basic unit of communication, not the operation. It is also called "message oriented" services. Most big software companies and industry analysts use SOA. It uses loose coupling because it focuses on the contract that the WSDL provides and not the implementation details that are underlying.
REST, or representational state transfer is using HTTP by stopping the interface to a set of well known, normal operations. It focuses on interaction with stateful resources instead of messages and operations. It uses WSDL. You can use SOAP with REST or not, it is really up to you.
Most web services that are not REST are often complicated and hard to use. Most SOAP toolkits have made it very easy to define new interface for interaction remotely and also use introspection to get WSDL. It can often be brittle because of this. There are also concerns with the performance because web service uses XML as a message format and HTTP and SOAP are used with sending but XML technologies are becoming better every day.
Any company that wants to succeed uses business and technology to satisfy their customers. It will help the business operate better when they want to use the latest technology, like the internet and mobile. It has really helped new business models become designed. The main business is the e commerce or e business. These businesses do their business solely on the internet.
Because most businesses do their selling on the internet primarily, web services are now very important. Basically, it sets up how the transaction is handled when a customer wants to buy your product. It tells the website how to process the payment and transaction. It is actually hugely important to most businesses because it sets up how easy it will be for the customer to buy your products.
If you have your own company on the internet then you may want to think about getting some advice before you decide which web service to use. You will really want to pick one that is easy for you and the customer but is also very reliable and fast.
