Thanks for your videos on Microservices communication, with Eureka, Fault Tolerance and API Gateway. I am sure it's gonna help me in my coming interviews.
Brilliant explanation and demo. It is such a noble work to give such useful resources on web for free. Eagerly waiting for your upcoming videos. Wishing you loads of luck.
Thanks Code Decode team, I got this channel while searching JAVA 8 video, I completed that and then MS series, waiting for more videos on MS, make video om Config server, Logging tech for MS, security handling and docker and openshift for deployment, it will be great help
I am a very big of your channel. Daily I am watching your videos for at least 1 to 2 hours. Could you add videos on microservice design patterns and architecture? Thanks in advance.
Thanks a lot ..U r a great teacher... but one doubt..Why did we have load balanced uri for both CITIZEN-SERVICE AND VACCINATION-CENTER-SERVICE in application.yml of API_GATEWAY? We need to load balance both these services as per the flow and both are handled by Eureka..In this point of view this is fine.. but We added LoadBalanced annotation only for VACCINATION-CENTER-SERVICE main app. Is this due to VACCINATION-CENTER-SERVICE consuming CITIZEN-SERVICE and reverse case ( CITIZEN-SERVICE as its not consuming any microservice hence not included loadBalanced annotation inside CITIZEN-SERVICE) ? Can you pls comment on this
I don't think @LoadBalanced is related to that lb propert of application.yml. The lb://CITIZEN-SERVICE tells the gateway to use Spring Cloud Load Balancer to resolve the actual instances of the CITIZEN-SERVICE. This means the gateway doesn't point to a static URL but instead leverages a service registry (e.g., Eureka, Consul) to dynamically discover service instances.
Thank you so much but do take care of your health 👍 A long awaited video. Hope you cover the rest of the topics in Microservices please like resilience4j, centralized logging, distributed tracing, RabbitMQ etc. before deploying into a cloud provider like AWS.
Thank you its wonderful explanation, now i clearly understood this gateway, One request could you make video of Kong gateway with oauth role based implementation please.
Thanks for the video, awesome explanation. can we have the video on the circuit breaker used for production? as you mentation hystrix is deprecated annotation now.
Thank you so much for giving this much explanation. This is very help full for me. Can you please share microservices example of this project for our better practice.
Since now api gateway is the only entry point into our backend application, it's very important to monitor it's health when it's deployed. It will provides valuable insights including the count of requests, total time taken, and maximum time taken for the API response. The above figures reflect the numbers. We already have a video on actuators. Do u need url for the same??
how can i dynamically change or update routes when application still running,b'cz right now if i need to add more services , i have to make changes in gateway yml file then rebuild and reploy the gateway application at the same time many request might drop , how can i avoid
Very nice explanation. Please help me with the below query: Suppose if we deploy our application in cloud, how does each microservice know where the eureka server is located ?
Very well organized content. Lucid explanation. Thanks for your efforts. Kindly complete the series with cloud config concept and other essential tools. To add more value can put video on deploying microservices in cloud.
Thank you for the video..👍👍 One suggestion, videos are not arranged jn playlist correctly. Please arrange in sequence, it's difficult to find and watch the videos in correct sequence for any topic.
Hi, Thanks for all your effort! Great help. For high school students can u teach Java? We are impressed the way you teach. Please help ! Will be of great help.
We would love to teach kids but we all are working IT professionals. It's very difficult to spare time and create videos only. But whenever in future we get some spare time we will let you know 🙂👍
This was the cleanest tutorial regarding the API gateway. But API gateway is kind of pointless without authentication and authorization right ? Would be greatful if you made some tutorials on how to achieve these, maybe using Oauth2 or something..
what if there are same url mapped to a method in different service? how api gateway will identify? Thank you very much for your efforts and sharing your knowledge.
why can't we just use service discovery itself? using service discovery too we are not remembering the port and host name for any backend Microservices right? so what exactly is the need for api gateway?
HI Chandu, U are not remembering host and port but u have to remember application name atleast to use Eureka / service discovery We don't want front end people to know any thing about our microservices. We just want them to call us using simple names in url and we will redirect them using simple English words to proper microservices. That work is done by gateway
But when I try to call from Front End http calls It will show up Cors. It is only working for Get api but others. I tried with Cors as well. But I did not get any solution
Thank you so much for your videos. I have couple questions could you please help me on this. I would like to know how API gateway application will monitoring, logging, authentication, Authorization . 1 . Logging menas ,Aussume that we are hitting vaccination end point from API gateway application once we received response from vaccination app we can print that response data in API gateway app , if it is possible how we will print. 2.Could you please create one small videos on how API gateway application will monitoring, logging, authentication, Authorization . 3 .what is the difference between Apache kafa vs API GATEWAY. Both are getting response from another microservices . a.in which scenario we will use API gateway and Apache Kafka. Could please help me on this . Thanks.
@@CodeDecode I implemented the vaccine citizen Microservice where citizen service is the fault tolerant one as I implemented the circuit breaker in vaccine service but how to make the vaccine service fault tolerant? In one video you told that Api gateway will help in that but how to write the fallback method in api gateway.
this is very good tutorial for fresher as well as experienced guys. please post these such informative videos ... Thanks a lot...
Thanks 😊

Good explanation mam
thanks
Thanks a lot. Really well explained. Waiting for upcoming videos. Are you coming up with cloud config video soon
sure sanjela we will create it soon
Thank you for this video.... I am not understanding why spring actuator dependency is added

It will provides valuable insights including the count of requests, total time taken, and maximum time taken for the API response. The above figures reflect the numbers.
We already have a video on actuators. Do u need url for the same??
It is amazing !! It will be more help full if you provide code base link.
how can i dynamically change or update routes when application still running,b'cz right now if i need to add more services , i have to make changes in gateway yml file then rebuild and reploy the gateway application at the same time many request might drop , how can i avoid
Thanks alot!! Really helpful
You're welcome Abhinav
Very nice explanation. Please help me with the below query:
Suppose if we deploy our application in cloud, how does each microservice know where the eureka server is located ?
Thnks long wait
Yeah we apologize for the delay Amit. Thanks for bearing with us 🙂👍
Very well organized content. Lucid explanation. Thanks for your efforts.
Kindly complete the series with cloud config concept and other essential tools.
To add more value can put video on deploying microservices in cloud.
Sure Vengatesh 🙂👍 we will do that
Kindly consider doing videos on logging testing and caching...it would be utmost helpful
Yesss we will do that sreeja 🙂👍
very nice explanation of Api Gateway .
Please upload video on cloud config.
Sure 😊
Nice explanation, please make a video on available clients for calling third party apis like restTemplate , web client, retrofit etc?
Thanks once again..done a great job..
Can you pls share the link for Cloud config tutorial which u mentioned at the end of this video
Mam pls make video on Role based Authentication and authorisation through API gateway for all micro services.
Amazing explanation. can you give the access to code base as well?
@Code Decode
Thank you for the video..👍👍
One suggestion, videos are not arranged jn playlist correctly. Please arrange in sequence, it's difficult to find and watch the videos in correct sequence for any topic.
Sure Sagar, we will surely work upon it 🙂👍
Hi,

@@CodeDecode 😊that’s ok. Thanks for ur time in replying. God bless u & family!🙏
Thank you good content..
This was the cleanest tutorial regarding the API gateway.
But API gateway is kind of pointless without authentication and authorization right ?
Would be greatful if you made some tutorials on how to achieve these, maybe using Oauth2 or something..
Yes we will integrate authentication and authorization in it soon 🙂👍
what if there are same url mapped to a method in different service? how api gateway will identify? Thank you very much for your efforts and sharing your knowledge.
Great tutorial thanks a lot.
I understand limitation of Zuul, but can you suggest why not recommended to use AWS or Azure api gatway,. ?
bcoz of its cost
please help me the query how to identify that request came from web or device and return the corresponding response?
why can't we just use service discovery itself? using service discovery too we are not remembering the port and host name for any backend Microservices right? so what exactly is the need for api gateway?
HI Chandu,

@@CodeDecode makes sense. Thanks a lot for clearing really appreciate it 🤝
Glad you asked your queries and didn't keep it to yourself. Much appreciated. It's the first step to learn
If you can share your git source code, then it will be more helpful for a lazy developer like me, Thanks for the nice summary on API gateway.
Here you go : github.com/codedecode25/Microservices_vaccination_citizen.git
@@CodeDecode Thanks Much
Anytime 🙂👍
Thank you so much.. Your explanation awesome. Please cover resilience4j as well.
Sure Praveen we will cover it soon 👍🙂
Hi could you please share the source code of the gateway you have given example of.

It will be very helpful. Thanks
Thank you so much for your videos.
I have couple questions could you please help me on this.
I would like to know how API gateway application will monitoring, logging, authentication, Authorization .
1 . Logging menas ,Aussume that we are hitting vaccination end point from API gateway application once we received response from vaccination app we can print that response data in API gateway app , if it is possible how we will print.
