REST Vs SOAP - What is the difference? | Tech Primers

[Music] welcome to tech primers in this video we are going to see what is so and how is it different from rest and we are going to compare soap and rest and see which is better so if you are familiar with soap so soap is a simple object access protocol so you can transfer soap objects in terms of XML format over HTTP protocol and then you can use those objects and formulate those objects and then do whatever you want with that so why do you need soap right it is important to create a application which is which your it which you are able to communicate over the Internet so that is when soap started so initially when soap started people wanted to transport data from one website to another or they wanted to ship data from one place to another over the Internet so that is when soap was invented okay and so what it did is it wrapped around lots of stuff inside it and then it was shipped over the HTTP protocol so basically soap has lots of building blocks basically if you notice here this is the skeleton of a soap message so you can see an envelope you can see Heather's body you can see some data inside that called fault okay so in general soap has a specific type of format like you have to have a name spazio to have differents type attribute so for example you see here there are different types of attic attributes and stuff like that so you need to have all those things but in terms of the rest you don't have to do any of those so if you notice here this is a typical dressed message so you have a successful success which is false and payload you have some data and then there is a error code touch it so that is the rest is as simple as that so rest is nothing but representational state transfer so so how are they different right so how what is the difference between soap interest both are in HTML HTTP transaction over HTTP protocol but still how is it different right so if you notice this particular a column so it clearly shows the difference between the soap and the rest protocol so soap is basically xml-based a message protocol however rest is a architectural style protocol so we will see in depth about rest in in few moments so let us come back to soap right soap use something called a blaze diem format for communicating between the producer and the consumer okay so however rest with rest you can do whatever you want so you can even use XML or you can use JSON so whatever data we saw here this is JSON data so this is nothing but JavaScript object notation okay so that is an imitation if you want to transact examines you can do that as well interest okay also smoke soap invokes the services by calling the remote procedure calls however rest is all like URL path okay so soap if you notice your soaps responses are not that much readable so it takes a while to understand it has so colon envelop so cone body and stuff like that however rest in terms of looking at it it is easy for us to understand since the okay error has code and message something like that okay so that is a difference in the india readable format okay also the transfer of soap is over HTTP most mostly the rest is always HTTP you can use as some TP FTP etc and so also those another thing is a JavaScript can easily call the soap but it is difficult to implement however interest rate so you can easily call the rest message or you can easily call the HTTP endpoint and get that message in JavaScript very quickly because if you are using JSON it is very easy so Jason is nothing but JavaScript object notation so okay so the performance is not great compared to the sole and soap if you see it's heavy bite it can notice a soap message it is heavy very tight so you are just sending a price and you have to write so much of code for that your you are having basically lots of ceremonies which we don't require however in terms of thrust all gone you just concentrate on whatever data you want okay so that is why rest is always having better performance than soap so if you notice the Martin Fowler he has proposed a he has created a blog post on the Richardson maturity model so Richardson is a person who had created different levels based on the rest approach okay if you notice here he has created a different approaches or levels basically called as level one level two level three okay that's what we are going to see what is this level one level two level three all right so before that we have something called level zero as well so he has a name for that level zero but if you notice by default soap is level zero so basically whatever you transact over the HTTP protocol okay so that is all level zero so soap is you can come sector data by HTTP so soap is level zero okay so that is what is mentioned here so I'm not going to go in detail of what is what but I will just brush up so that you can easily understand so our other easy way to understand soap and rust is consider and envelopes right so soap is like an envelope so you have an you have a cover and then you put something you use soap you put your paper inside the envelope and then pack it and send it over so soap is something like that however rest is like a postcard so if you see a postcard you it's all open right so what about content you have it's all open so that is like rest of something similar so it is not that much secured but you can make it secured internally in application however soap if you see it is much secured and it is like not everybody will able be able to take hold it quickly you need a WSDL to decode stuff and something - ok so that that is the basic difference between soap and rest so in terms of understanding right so the next one is the level one or so so level one is like what - I said there what mm Richardson says is that you need to have a resource basically so resources in the things you need to have rest endpoints in terms of resources for exam instead of having a big resource you have a you introduce any cultural sources instead of having a big recent point you have instead of having a single rest endpoint you have resources basically for example if you notice in this particular example it says dr. slash and Jones and then you have slots one two three four so you have different rest endpoints so basically these are different resources rather than having our single rest endpoint you can easily query based on a particular source so you can say slots one two three four and then you can get that particular data for that particular resource so those are called resources so rest is majorly concentrated on resources so that he can easily update those reserves for example I can notice here you on that particular resource you can do something so you can do a post for example on the particular associate or doing an appointment so on that particular slaughtering an appointment so so you can do operations on that particular resource so that is the level one too so the next one is the verbosity so in HTTP for us try TB you can create URLs in terms of verbose so you can you can have a resource path in terms of creating verbal communication like the for example if you notice here these are like dr. /m Joan slash law so this clearly shows that this particular this point is specific to M Joan's slot and he is a doctor again if you notice here the other one under the slots there is a number one two three four so you can control the one two three four slot number one two three four a separately so if you notice here the location is also four incisors law says one two three four slash appointment so you can do you can cancel the appointment or create upon mother stuff like that you can do all right and and if you notice here the names are all Nick Bobo's so I'm not saying get slots or I'm not saying get M Jones slots or something like that okay so that is the level 2 that is what Richardson says the last one would be is the hyper media control so you have something called hey TOS so hypertext as the engine of application state so base you have links within lennick so if you notice this particular response right you have response and internally inside the response you have a link to another rest endpoint basically so I'm saying that okay for the dr. M Jones the link for the slot ID one two three four is this so basically you have you can access another restrain point from this restrain point so that is what the hyperlink the 11:3 says the hyper text or they have the media control so you can have hey tio is implemented as well so you don't have to worry about linking the data within the same response so you can use that as well so that is another major change over in Vegas right so these are the different differences between soap and rest so if you notice arrest is very lightweight and you have lots of control over wrist it is all verbose you can do hypermedia controls as well so that's where rest is popular now if you if you personally ask me a rest is better than soap I would say you add yeah there is a security concern and so but however in ended rest actually but you can have controls in the application using like if you see the latest of spring security in spring MVC right so you have lots of security options inside spring MVC you cannot think security and control your secure your first ten points based on authentication and authorization of different mechanism so it is it is lightweight and it is good so rest is lightweight and indirect is good so P on the other hand is it is heavy weight and and it is outdated if you ask me personally so so that that is the difference between the soap and that is hope you understood what is the basic criteria between soap and rest so choose your protocol wisely okay so until then make you again in the next video until then see you you
