you earned a new follower, it was the first video that I watched in your channel but it was an amazing time, it helped me to implement an API gateway at my job. I proposed use one to create a scalable architecture but I was finding some problems to implement it using nodejs, so now it's more clear how to solve this challange. Thanks guy

Nice idea of presenting information with that glass board and luminescent markers, but for this kind of scenes Manual Focus mode on your camera would work much better - just set it once and don't touch =).

Man you are awesome and your studio style and lighting is awesome. It got me concentrating for the longest period. The only thing I would recommend is to turn off autofocus and manually adjust it once.

I really liked the content and the way you presented. Great Work! But you need to fix this auto-focus thing.

Dude these videos are awesome. No beating around the bush. I like it

Thanks Houssem, clear, perfect. Exactly what I needed!

Wow, one proper video about API gateway without beating the bush !! hard to find such clear explanation on this topic .

I absolutely loved this video and the simplicity. You created a fan brother!

You have done great job with the presentation. Keep up the good work !

Great video man, future videos perhaps consider turning the auto-focus off.

loved this - very articulate and exhaustive

Superb explanation . Worth watching and thanks a lot .

Excellent video man thanks keep them coming

Became a fan of your presentation, very clear and basic explanation. Just like someone has read whole chapter of an interesting book and giving concise gist of the content. Looking forward for more videos on this. Would you be able to get an tutorial on api gateway end to end.

Excellent video. That's how new solutions should be explained.

Thank you for this simple explanation.

Very helpful.thank you very much.need more videos from you.

great explanation appreciated your effort !

Great explanation, thumbs up

Wonderful and amazing explained with specific details. Thanks for sharing your knowledge.

The content is amazing!

Great explanation. I'd just like to add that a "single point of failure", in my opinion, is not really a drawback. Because if a monolithic application crashes, it's also a single point of failure. With microservices, there's a chance that only a service crashes and everything else keeps running.

Thanks for the video! Nice presentation and very useful information..

What a great explaination!

I love the way you explain...

Best explanation, thumbs up

Deserve way more views

Loved the explanation. Simple and to the point

I still get loss. I wasn’t fast in learning an automobile stick shift either. You just have to learn it. A lot of people grew with it. No experience.

thanks for this awesome and useful video.

Thank you so much! Your explanation was very clear!

Great job ! thanks , I like your manier to expose your explain

Explained really well. Only thing that's disturbing is the camera focus going haywire. If you are using DSLR, then adjust the camera to focus on a single plane, or if you are using phones to record, there's also an option to lock your focus. Videos are really helpful.. thank you :)

Great explanation! Thanks!

Great Video! For learning and understanding API Gateway, it is very useful to me. Thanks!

Thanks so much for this tutorial.

Thank you, sir, for such a nice video and knowledge.

greaaaat information :) Thanks Houssem

Great presentation thank you

amazing Hussam, Thank you

Great explanation. I loved it

Good explanation! Thanks.

thank you - nicely done

Great explanation !!

Wonderful explanation of Api Gateway Concept

its really nice video regarding API GW

Nice Presentation!!! 👍👍

Great explanation

Of course I liked it! Thank you man

Just Brilliant.

Great Job!!

thanks it helped to understand ,

Great content sir

this is really good

Amazing!

Thanks) It was very useful.

thank you. nice explanation.

it's such a great content and explanation, could you please post one example on how to build (design, coding) gateway like using (nodeJs)

Very cool. Thanks

que buena introducción!

Excellent!!

Great video that explains very easily the API Gateway purpose. However, I would strongly advise against implementing the Orchestration/Business Logic (BL) in the API Gateway, how much tempted you might be. Create a BL layer between the API GW and the different Microservices, in that way you cleanly encapsulate that functionality in a separate module (microservice) and let the GW strictly do GW stuff. It will also make the load balancing, and future maintenance, easier since that functionality resides elsewhere. Clean and neat separation of concerns and responsibilities; future proof solution. Trust me, thank me later. Keep up the good work 👍🏼👏🏼

i was also thinking the same, by having the api gateway implementing the aggregation logic it will make the system brittle and would require frequent changes at gw, and all in all it will result in resistance for the future of the application

Nice explanation and what ever you have explained is sync flow of API so can you please explain Async flow(message broker system) it will be helpful for audience and followers And one more small request , please explain those authentication and authorization over API ,it's token based authentication over API and TLS between Web GUI and API gateway , finally I'm appreciating your technical knowledge sharing attitude

good explanation Houssem. I wanted to have your suggestions on the API gateway. when it comes to optimising the gateway, normally there are several back and forth request and response transactions that tend to increase latency. instead if we did something like creating a lookup table at the the gateway and tokenised the IPs and stored them in the lookup table, just like how credit card tokenisation works in credit cards in eommcerce applications, that addresses both the security as well as the latency problem. do you think that is an advisable optimisation? and yes, ditch the autofocus next time? lol :):)

m3allem ! Great explanation

Thank you!

Thank you so much

is this the same logic for the aws api gateway?

great video. thank you. why not disable the auto focus?

A very unique way of presenting. Good work and it was really helpful. The video was going blur in between so you may want to check out to avoid this.

Now got clear understanding of API Gateway.. If you can create another video on security and Api monitoring will help

Thanks for your explanation. 'Request/Response Transformation' seems better naming instead of 'Query Transformation'

Hello friend. Excellent video, the concepts were very well explained. I have a question. You mentioned, at some time, that API gateway help you to eliminate the circuit break pattern from microservices. But, (maybe is my misunderstanding) circuit breaks were supposed to be applied on client level. Am i right? If so, thus the circuit break pattern was removed from your Web App, rather than microservices themselves.

So do you wrote it reverse, dude ?

Thanks man

Great content and novel delivery. The autofocus is really distracting though.

graet explanation

Thanks a lot, awesome content. I would like to recommend you to turn autofocus off on the recording device. I also have a question; what is the lifetime option in API Gateway, I guess it's scoped.

Thank you Houssem for the great video. In term of security, would you please explain more why API gateway improves security? To me, if the the single IP address of the gateway is exposed, the hacker can explore all microservices. W/o the Gateway, the hacker has to know the IP addresses of all the microservices to do the same.

Whole point of services is you want to allow them to consume but in a secured fashion.If all these services you want to expose w/o gateway, then you will need them to have public ips and each service will need to implement Auth. With gateways, you just need to implement Auth at gateways level and allow/reject at gateway level based on Auth flow

Great video. Btw, you should disable autofocus on your camera.

Such a great video. Crystal clear explanation. Great work buddy.

thanks so much

Great!!

Thanks for sharing the knowledge on how API Gateway works at a high level. My question is how the actual implementation of API Gateway happens, between client webapp and API Gateway.? There will be only on url call between client and API Gateway, and APIG will call the different microservices, then how the API gateway will understand to call different MS .? who is responsible to configure it and how the request and response objects will be configured in the API gateway.?

thanks :)

Actual information about API gateway starts at 4:36

Wonderfull

Could we have authentication and authorization also as a microservice rather than repeating code in each micro-service?

@HoussemDellai

Hi Anil :) Yes that is possible. What is recommended is to implement AuthN in the API Gateway to not replicate code and AuthZ in each microservice to have more granular role management.

@JamesSmith-cm7sg

@@HoussemDellai How will each microservice know the roles of an identity ? Isn't it better than the api gateway itself will check authorisation and the microservices can execute without needing to check?

Sometimes a service response is dependent on other service e.g. order is dependent over inventory so do u suggest to put all such business logic in gateway or do you advocate svc to svc internal connection as well ....If so authn &authz to delegate at bkend svc as well

This is an example of "just add another box or layer" without clearly understand or explain why. As other commenter said, it has the same "single point of failure" the mono application, then why do we need this? What happen if you combine the API Gateway with your Web application? it provides the same benefits, in this case you only expose the IP of your web, why do you need to expose the IPs of your services? One key element for microservices design is to provide partial operation, meaning if one service down, the app is still running, by your implementation, I see if 1 service down, the whole app down. It is a different story if you have a mobile application when the app is running on a "external" device. The the API Gateway makes sense, but normally, you can't reuse the same gateway you build for web.

Please use manual focus option on your camera.

@ 8:12 - I believe the API Gateway doesn't necessarily have to have a public IP address. Since the API Gateway should ONLY be accessible by the Web app. The Web App since it's public-facing, should have a Public IP, and contact securely using a Private IP to the API Gateway to access all of the microservices and dependencies therein.

you may want to expose your services to third party or open source

thanks

Kindly make this video with practical session with AWS with EC2 instance using Micro service.

7:50 Is the microservice from 1 to N lying on the company's internal network?

Nice

I am looking to deploy apim in the standard tier. I don’t want any public access therefore going to put an appgw infront of it for external access. Can I use a private endpoint for apim and then remove all public access? Then connect to the other components e.g dev portal through the PE?

Hmmm does the idea of such a service break the SRP? It looks like a service with a massive array of responsibilities and it also looks like it has to know a bunch of stuff about all the other microservices. I'm not sure cos I have no experience with the MSA, I'm just learning about it, but seems like maintenance of this API gateway may well turn into a sheer nightmare. Also, what if this service breaks, then the whole thing will stop functioning...

That's pretty amazing you can write backwards like that.

I am also an tutor, can you please help to let me know from where you bought this screen, please share the link. I am interested to explain on similar screen.
