Introducing Spring Cloud EUREKA | HOW TO DISCOVER MICROSERVICES ? Service Discovery | SPRING BOOT #6

The nuts and bolts of Spring cloud Eureka discovery server, Let’s cover it in this extended lesson. In this video we will learn to implement spring cloud Netflix eureka in our microservices. The services that we usually write should be container friendly , hence will be having dynamic url’s . In that case, communication between different microservices will be tricky as all the service url’s changes every time. Service discovery and service registry is a pattern which comes for rescue. We made all our microservices , a client to a discovery server which keeps tracks of all the service urls.
When a microserivce wants to connect to another , it reaches to the discovery service and asks for the url of the destined Microservices. Once the discovery service returns back the url info, the calling microservice makes a call to the destined Microservices using the service url.
So as we understand, we need to build couple of things. The step 1 is to build a discovery service where my services will be registered. The spring cloud in collaboration with Netflix eureka gives us a powerful discovery server called spring cloud Netflix eureka which works seamlessly to help discovering all our microservices.
The step 2 will be, adding the Netflix eureka client dependency in our microservices which helps our microservices to register with the discovery service when they bootstrap.Let’s say if we have a hundreds and thousands of microservices , we will make all these services a client to the discovery server so that they can register themselves with the discovery server.
Let’s learn this concept step by step. Implement, do discovery service configuration and learn all the foundation that you need to work in a microservice environment.

I am just wondering to see the no.of views are very less. This course is one of the GEM. and this channel deserves all the credit.

[@SeleniumExpress]

Thank you!

[@santhoshchandran6952]

Exactly

[@JohnDoe-ej6vm]

Microservices are not for beginners that's why :)

[@JohnDoe-ej6vm]

No doubt, best content.

[@kunalmahale2230]

The word "Selenium" somehow misleads one to think more of a testing than Development. If named something with Spring suffix / prefix would help. "Spring Express" maybe. Course Content is really good Great work

[@aprajitakasyhap8430]

That's great to hear! 6 years ago, I learned the Spring framework from your channel and successfully aced my interview. Today, I'm here to delve into microservices. Your course offers a clear understanding of the concepts and a practical approach that I find very beneficial. Great Job Abhilash.

[@tusharmusician]

I watch your videos everyday for 3-4 hour , thank you for providing best content without any cost

[@SeleniumExpress]

My pleasure ❤️

Hi. I have one question . How you have createt two microservices in address-service? Thanks

[@santhoshchandran6952]

Thank once again

[@SeleniumExpress]

Welcome, Santosh!

[@supriyavangeti8127]

Hi, I just watched your video. It was nice , but I didn't got which dependencies u have add in the beginning of the code. So, Can you please say it ?

[@amiyarout217]

feeling great

[@ucgiangnguyen8009]

can you please explain the difference between eureka discovery and api gateway?

[@rovinsingh681]

Hi, Abhilash thank you for uploading such videos. great tutorials. I have one doubt. what will happen in the case of the below configuration server.port=8084 spring.application.name=discovery-server eureka.client.fetch-registry=false will discovery-server trigger peer requests in every 30 seconds?. For me it is doing . but as per my understanding, it should not as we declaring "eureka.client.fetch-registry=false" configuration.

[@srigakolapuatchuthasai5929]

Thanks abhi ❤️

[@SeleniumExpress]

[@truecompiler]

Hi Abhilash, is it possible to create the discovery service inside the employee service or address service application or every time we have to create a different application for discovery service? Thank U from Delhiites

[@arvindnigam3134]

How many hours of episode are left please reply i am about to start this series

[@khushalijiyani6310]

Hello Abhilash hope you are doing well, whenever someone from the class is asking any question to you it's not audible clearly, so can you please add text for that time while you are uploading video? It would be very helpful. Thanks in advance.

[@letvarconst]

Yes, you're right, Abhilash pls consider this

[@damilola_adegunwa]

@SeleniumExpress, is it reasonable to have multiple disc-services on the same server? also, in case of multiple disc-service on the same server, do they do leadership selection? (or would every disc-service be calling every other disc-service to get update)

[@digvijay1228]

Can we run the discovery server without having the eureka client dependency i.e by excluding the eureka client dependency from eureka server dependency.

[@satyaranjannayak6283]

Nice course sir, expecting faster video upload

[@SeleniumExpress]

Hi Satya ! There are few more videos to come. Will wrap up in couple of weeks. Next video will be on Saturday, this week.

[@satyaranjannayak6283]

Nice sir

[@SeleniumExpress]

Thanks, Satya !
