When/how REST replaced SOAP

[GarciaPL]

Hello,

I am currently writing my thesis about IT technologies etc. etc. and I have one chapter where i compare REST and SOAP, but I can not find how and when (i mean some king of events in the past) REST started (mainly in Web) to replace SOAP as technology of web services.

I would like to show you a graph in Google Insights for Search Tool :

Google Insights for Search

As you can see in 2008 there was some king of intersection number of keywords searche for rest api and soap api. So, i would like to rely on some sources (of coures I do not have them) or events/facts why this intersection may occured... event in the recent past.

Do you get my point of view ? I know that could be quite unique approach to the topic, but i would like to explain of this soap and rest swap.

PS. Sorry that i put this topic to XML section, but i can not find any similar section related with topic

hm, IIRC SOAP and REST are not as compareable as you think. while SOAP (a protocol) is a remote service (something dynamic, you send data and get a result back), REST (a paradigm) is about states* (something static, you always get the same response out of a request).


* - remember, HTTP is state-less

[GarciaPL]

Yes, i know. But of you notice the web services in Web are generally built using REST and SOAP. So I am wondering which events have influenced the current state of affairs, I mean why there are so many REST services.

SOAP is a protocol and as such tied to its specification. REST is a paradigm, you can implement it however you like.

[GarciaPL]

Yes, I know about it ;)

But look at this page : http://www.infoq.com/news/2011/06/Is-REST-Successful

there are some statistics about REST and SOAP, right ? I am wondering, which events in the past give that REST is now mainly in use in Web ;)

[Dormilich]

isn’t that obvious from your source and my answer?

[GarciaPL]

Yes, you are right, but i mean which companies started to implement their servies using REST. When was the change in the attitude of companies, change in approach to developing Web services ;)
