Here we go with a bang on Saturday to learning revolution. Thank you for all the effort sir. Will be awaiting for the next Saturday also for the same Josh ful session.
Thank you so much Abhilash for sharing such an informative session for free. Really appreciate your efforts..!! Best explanation available on youtube for spring boot microservices :)
Thank you so much for explaining these concepts very easily. And love u so much sir❤ because you care for new learners. thank you so much for that. You are the best teacher❤
I learnt from your videos especially this series ,thank you soo much..i trying to learn microservices with my java knowledge but no udemy course help me to understand ...Thank you soo much when you providing any course online next ,please let us know ,i am interested to enroll
How often the cache is updated in discovery client, if another microservice portno got changed, it is updated in discovery service, but how the discovery client will get to know other portno got changed. As registry information was already pulled and updated in discovery client cache.
Hi Abhilash, I have doubt. I know whenever a request hits server it will use one thread from thread pool and process that request. Load balancer which we use in microservices is used to reduce load on one server and distribute our request equally in respective available server. My question is what if many request hits load balancer and it is out of threads. how this is handled?
Abhilash bro i have one question actually two 1.So when developing a distributed sysyem what should i choose client side or server side load balencing . Or both necessary but for me it lokks either of one is needed 2. This is about Discovery service in both client side and server side load balencing is the discovery service same i mean is it the same library or microservice. Is it the developer resposiblity to configurd that in both cases of load balencing Please if anyone know the answer pls reply ?
In one of the slide you mentioned all the services [either caller service(A) OR Target Service (B)] having information that how many total services[A+B] are running including Discovery Server but I think only Discovery Server know this thing and it handed over this information to caller Service i.e. A when it make a call to Service B - Please comment !
Hi Ajay. Thanks for posting a comment. If we talk about Eureka , as a discovery Server, all our microservices are client to eureka server. When all our microservices started, they try to connect to the discovery server and get the entire eureka registry and caches it . So when our service A, B starts, a background thread get the entire eureka registry and store it in the client side. so when A is making a call to b, A knows how many instance of B has, and call one of the instance in a load balanced way. B has nothing to do with it , it just accept the requests and serves it. but yes, B knows How many instances of A are running which it can use to communicate with A whenever needed. (It has nothing do with how many A servers are there and it just serves the current request) In our follow up lessons , we will have 2-3 hours practicals only on this things. You will find that internally all the eureka clients makes rest calls like eureka/apps to fetch all the registered apps and they make follow up delta calls to stay updated with Discovery service.
Appreciate the content. the way you described is really awesome. it is crisp and clear and I am awaiting for this whole series. nice work done by you. Kudos to you , hope you launching the series faster.
I really have to say this. The intro and outro bgm is damn good. Apart from the good technical content you have worked on video quality as well and it is clearly visible. Thank you so much for the efforts.
for example we are using angular for front end, from angular i need to call service A , so one festival time their are lot of hits to service A how do we need to handle the Service A which is connected with Front End server Sir can you please help to get some clarity ?
Thank you for detail explanation.! Could you please also explain what are the use case of server and client discovery and where to use which one and what are benefits of both on each other?
Hi Abhilash , my spring boot application is deployed to gcp , gcp has provided us one base url so event if the number of instances increase that base url doesn't change gcp automatically load balance it , do we still need service registry here ?
Is it correct, In Server-Side-Load-Balancing having 4 entities [Caller Service, Target Service, Load Balancer and Discovery Server] where as in Client-Side-Load-Balancing having 3 entities [Caller Service, Target Service and Discovery Server] as a primary difference ?
Correct ! in the client side, client only do the load balancing. In the server side, the client doesn't do anything, it just dispatch the request to LB and then load balancer does the rest of the work.
Hi Abhilash. Thanks for creating such awesome content. I have got a doubt. You said front load balancer/traditional load balancer is not good as there are call hops. We are calling load balancer then load balancer is calling service B. Isn't the same thing happening with service discovery as well in fact here load balance is doing an extra work by querying service discovery and getting server details . Then how come this is better than traditional one ? Please do answer.
Traditional load balancer is not good because it's not supporting run time server scalup or scale down ..in real time ms application always this scalup and scaldown is needed
Hi Abhilash. First Thanks for tutorials. My question is from 33.00 min how service discovery and registration works. Que 1) When Server details (IP address and port number ) cache from discover service into both client and servers ? ( When we starts server ? ) 2) what will happen if we de-register servers from discovery service after caching data on client and server side Thanks...
Hi Akshay! Thanks for posting this question. I have added a lesson today with practical examples in today's upload. Please check Lesson 8 of this series. Keep me posted if it doesn't answer your questions
My pleasure, Suneel! Next Saturday, we will get started with the service discovery and registration - coding. We will use spring cloud Netflix eureka library for all the things explained in this video.
Thank you for the great video Abhilash! When we have multiple microservices do we store them in one repository or do we create separate repositories for each microservice? Can you show us what is the best practice? Thank you in advance!!!
Hi In server side load balance, u mentioned that we need to add services manually to service discovery that we need extra man to do this work. What about the client side,?
