Mule 4: API Gateway and Auto Discovery

[@jacekbiaecki8076]

Your videos are fantastic. I really like the way how you explain things (course of thoughts, detailed and concise). There is a lot of Mulesoft-related channels on YT but yours is unique. Thanks!

[@coolguyrbh]

As others have echoed, such concise and clear explanation. Thank you. I see the videos have dried up on your channel, we would massively benefit if you resume again bro. Thanks again!

I'm new to mulesoft, can someone please say what is the difference between implementation layer and orchestration layer ?? as per my understanding implementation layer is what we do in anypoint studio ( develop the api) and orchestration layer is where we deploy to the cloudhub ??

[@Vishwasp13]

Orchestration layer and Implementation both are part of Mule runtime. In earlier version of Mule 3.8.x and before the API Gateway (Orchestration Layer) was separate runtime later may be from 3.9.x it was embedded into the Mule runtime. So Mule Runtime = Implementation Layer + Orchestration Layer (API Gateway). Also, Anypoint studio is where you develop apps, runtime is where you deploy your developed apps to run. Anypoint Studio comes with an embedded mule runtime hence you can run your apps in studio as well.

[@samalmanoranjan]

Well articulated...

[@mayuria2447]

Hi vishwas ,thanks for providing so much information to us ,can we know what the most important policies in interview point of view that they ask

[@mayuria2447]

Sir what is the difference between API gateway version 1.0 and 2.0

[@manikantaadabala3122]

Nice explanation vishwas....please do one video on CI/CD pipeline

[@Vishwasp13]

Sure, I'll try to post a video on CICD.

[@TheAQUADEEP]

Excellent video . Vishwas if you could kindly explain how we can achieve a multiple Implementation API against a single API gateway that would be great.

[@Vishwasp13]

Implement a proxy and configure routing to the implementations in the proxy API, that's the best option I believe.

[@abhijith501]

Hi Vishwas that is really a good video.i am learning mulesoft and wanted to implement oAuth this is really helpful. One question i see you have added client_id,secret from access management once and also in exchange. What is the difference between both. And another question lets say if i want my application to be invoked by end users instead of we giving the client id and secret can they create their own client id and secret and invoke the application that is just created. And last question do we need to create new applications everytime and assign instance id to the new project created and request access for client_id and client_credentials

[@khadarshaik8012]

please do a video on Proxy VS Gateway

[@lopintipriya3510]

Thank you for the woderful explanation Vishwas. Im beginer to mulesoft , so sorry for the silly doubts .. Ok now, u mentioned about API gateway as the placeholder for configuring the Non - functional requirements, So is this Gateway has to be configured seperately , or gets automatically created , when you create policies [clientId,Enforcemen, Ratelimiting etc] on API manager ? and second one , you have created ClientId Enforcement policy on API manager , i guessed that you would pass this information in the request header with two seperate parameters , but you created basic authentication and added them as username and password. so is that the way we need to send those details or can i pass that information as part of header too. plz give me some infor abt it

[@Vishwasp13]

Thanks for appreciating my work. Doubt 1: The Mule runtime comes embedded with Gateway (Orchestration Layer as shown in video), which means its already there you need not configure it separately. The runtime has 2 layers Orchestration and Implementation, Orchestration layer is where the policies that you configure in the API Manager gets applied, the implementation layer hosts your mule code. Doubt 2: There are multiple ways to configure client Id enforcement policy, you can configure it by using the Credentials Orgin option available in API manager, it gives you two options 1. HTTP Basic Authentication Header In this case you need not configure anything, it automatically detects the client ID secret sent as Authroization Header with Basic Base64 encoded Username & password 2. Custom Expression Here you can give you own format like reding from query params, headers or maybe payload, using expressions like #[attributes.queryParams['client_id']] #[attributes.queryParams['client_secret']] Recommend you to do some hands-on that will give you much more clarity. Finally, feel free to ask your doubts no matter how silly you might think it to be and I'll try my best to answer it. When you ask doubt, it means you're learning things. Asking doubt not only helps you but it also helps me and may be others who read this comment.
