Out of all the tech giants putting out educational videos, IBM has the most visually appealing videos.

An SDK is just a pre-packages set of code (for a specific language) that you don’t have to write yourself. Sometimes free and sometimes you have to,purchase them. In the case of this video, he is suggesting a “API-Interaction” SDK a developer would use. There are all sorts of other SDK’s out there including things like an SDK to simplify building a User Interface.

Even before I can concentrate on the subject he is explaining, my brain is lingering on the board and its depiction, it is so amazing

Prior to 2000 and there is a period of overlap, API was synonymous with function calls to external libraries exposed by other modules. It could be local, in memory, inter-process or remote libraries (or set of libraries SDK), whether it was binary or textual. API's around 2000 became synonymous with HTTP SOAP Web Services, and circa 2012 became synonymous with REST Web Services.

I'm impressed that you wrote all this backwards, and didn't even screw up

i think this is the most clear and easy to understand video i've watched about api and sdk . love it, keep it up!!

I do not understand why some people put a thumb down ?? This video is design to give an overview of technical concepts. It does an excellent job and reach it goal, it simplifies those technical notions without giving wrong info.

Summary : - API : enables a system to communicate with another (without having to understand the complexity of the other system) - SDK : enables you to use APIs easily

Thanks for the explanation! That is the first presentation I see from an IBM person that goes directly to the point. Great.

This was absolutely simplified! Thanks IBM and amazing instructor

Perfect. Was struggling with these terms. Helped me get a basic idea to build on.

A nice short video by Nathan, but which gives a good insight on what SDK and API are. Thanks mate for your effort

this is pretty good movie clip to get basic understanding of between both. It is really helpful.

This channel is famous to make easy concepts complicated, hats off to you guys & keep up the good work.

API is also the library of interfaces to a desktop application or program. For example, you can integrate a program to Excel by using its COM API Interface. API is basic, it's only an interface. An SDK is more complete as it can have library API interfaces AND Tools to work with a specific technology. For example, if you want to develop mobile apps from Windows, you will need an SDK for a mobile OS, which is a complete set of tools to compile the code to Native Mobile OS, a debugger, an IDE, etc. etc.

This video gives me light for a design project of an app. Thanks!

이렇게 좋은 영상에 한글자막을 해주셔서 너무 감사합니다

10/10 in actually getting the point of the video across, keep posting content plz!

Very nice video... The one I was looking for... This is the kind of demo I or I think common folks like me, look for when dealing with these software abbreviations littering the entire cloud development ecosystem. Keep posting great videos like these.

The style of this tutorial is awesome.

Never knew programming was this easy. You have really open my mind to endless ways of developing solutions to problems. Thanks Bro!

I've watched many content about APIs. This video is definitely the best. Great job.

i love your explanation! easy to digest :) thank you!

I have been using api and sdk without knowing the terms for them! Thank you for the enlightenment!

Great video, I think this helps remind us of what an API ‘actually’ is…I personally tend to use the term API when I should really be saying ‘SDK’. I think another important concept to mention is that an API requires the logic to be hosted on 3rd party hardware, whereas SDK entails assemblies that you absorb as local references to your project and publish along with your build.

Great video. Sound of that pen on glass though...uff shivering

thanks a lot for this klarification its really help me to understant the concept of communication of an app

I save you some time here: API is if you make the requests yiursefl to an url to get, post, put etc. json data. SDK is a sort of module written by the service provider which contains functions you can use to complete your task. Example would be: upload_image("cat.png")

i am wondering how he learned writing reverse

A nice explanation. And I loved the board.

Nicely explained!.. Thank you so much!

These is a crestal clear example. I really appreciate your effort and method of education. great thank you as I wish to see more and more of this videos.

Definitely loving these videos from IBM. Thank you for these!

great and clear introduction to the terms

Awesome video! You made it pretty clear and straightforward for us! Thanks

Dear IBM Cloud, you disturbed me with your creative board and the talented trainer. Due to the amazement, I could not concentrate on what he is teaching. You innovated a little more than what you need to.

Amazing Board technology and nice describing, easy telling story about mittens great job.. Brother

명확하게 정의해 주네. 이런 점 좋아요~

Amazingly explained 🔥

Very succint. As a brief intro, it shines! Thanks, man.

Whoa, this is a exceptional vídeo about API and SDK topics, my english needs a upgrade, but thanks was necessary!

great explanation👍

Very easy to understand API and SDK. Thanks

I’ve loved this board since day one.

Thank you Very simple and nice explanation

Very nice explanation!

Hi. i just discovered this video and it's great. Thanks for that. I have a question: once the tool box created, is there any best practice to maintain it please ?

A wonderful explication. Thank you.

Thanks for the video, the drawing is actually very helpful to understand between these two.

Amazing explanation

Very nicely articulated- I love it!

perfect explanation 😍😍😍😍thank you

That was so perfect. Thank you!!!

Thank you! amazing tutorial, clear and solid explanation.

Thanks ,a colorful presentation on api and sdk. very helpful.

I understand now what all this means, but sometimes you are just looking for simple definitions: API is a URL that does something (retrieve info, change something or perform an action). SDK is a file or files which have libraries that developers download and use in their proyects. Then it comes everything else that you brilliantly explained.

Good, clean explanation!

This is a good explanation. Thank you!

These IBM videos are NOTCHES above the google ones . Great stuff !!

This is one of the best videos I've ever seen on youtube!!!

Excellent explanation, thanks.

One quick question As per the details , the SDK is a tailored ones and the API's are the joining edges of that which will make a complete product (app/SW) development, right? Also I think that mostly API's can't be alterable. Correct me if my view is not appropriate

Great video & excellent explanation 🙂

Awesome explanation. I was struggling to understand it.

That screeching… I am dying here. Great content!

Thanks for making it so simple

Thanks for your helpful tips about SDK and API

great explanation

Great breakdown Nathan.

Without SDKs we would need to send API requests using low level HTTP commands in whatever language we use. For example: Wanna talk to the Stripe API to get customer info using PHP? Without an SDK you probably need Guzzle HTTP library to send several requests to the /customer/ endpoints while needing to pass authentication credentials each and every time in your code. With their PHP SDK you aunthenticate once within your scripts and use the Customer object to get customer related data. SDKs facilitate using an API but are not the API and are not guaranteed be offered by the service/company that published the API. On the other hand, consuming the API using lower level commands offers us more control depending on how deep the SDK was implemented or not. I highly recommend checking out Stripe’s APIs and SDK documentation to get a good example of amazing implementation.

Nice explanation

vary impressive way to teaching in remote by glass wall and inverse image filming.

Beautiful explanation

The down side of the SDK is its size. It has many funcrionality that one app might not use, also as SDK should be consistent over time, it should have the older versions which make them even larger over time. Also, as they run on our thread, they could have security issues, as well as malwares. It is better to make a good document for API vs an SDK. But big companies like to creare SDK to abscure data from developer. So never use an SDK unless it is open source.

Thank you,it helped me

The main difficulties of existing API multilevel systems are: 1.The difficulty of porting a program code from one API interface to another. 2.Loss of functionality upon jumping from lower layer to higher.

Wow, that is really simple straitforward explanation..

아주 재밌고 유익한 영상 잘보고갑니다 :) 앞으로 많이 많이 찾아봐야겠습니다 :)

Awesome explanation

Brilliant explanation

This guy is way ahead other explainers in youtube, nice charsima, speech and gestures, and nice looks

1min in the video, am like "gotta sub this channel". I love how calmly he explains things. Need more from this guy

Thank you for very useful videos guys! You're great!

Excellent - very helpful. 👍

Very nicely done! Informative…

So informative! Thanks so much

Cool video, explained beautifully 👍

Thank you, it helped but i had a little bit of problems. Good Tutorial

Thank you for the information!

I'm interested in they way you film this video. Is there any special equipment or just pure mirror and dark background

How the heck do you write like you write on a mirror...this guy is a genius!

It was superb how he wrote his explanations in reverse 👏🏻👏🏻👏🏻

Fantastic video, thank you!

Great explanation! Thanks! :)

Great presentation!!

Could there be more key differences eg. Sdk is responsibility of coder, etc? Is java API? I thought it was interchangeable in the past

This is an awesome video, but that is the doggiest cat I've ever seen.

in the java code above where would you mention the end points is it when we try to instantiate the visual recognition object somewhere before the code in the video?

this video blow my mind ,, great video

Hi, Thank you. It was great. please make more videos like this. best of luck.
