- The High-Level Architecture of the project
- The Logical Architecture of the project
- Building Product Service
- Writing Integration Tests using Test Containers

[@ProgrammingTechie]

The tutorial series and the upcoming parts includes some changes below compared to the previous Microservices Series: - Spring Boot 3 - Integration Tests using Latest Testing Techniques - Spring Cloud Feign for inter service communication - API Gateway implementation using Spring Cloud Gateway MVC instead of Spring Cloud Gateway with Webflux - Add Circuit Breaker Logic in API Gateway - Security using latest Keycloak - Distributed Tracing using Grafana Stack instead of Slueth - Deployment using Kubernetes Link to Written Tutorial: programmingtechie.com/2024/03/28/spring-boot-microservices-tutorial/

[@user-ez6pm6hi8z]

Sir, will the entire tutorial be free

When part 2 is coming?

[@defrankline]

Kindly implement oauth2.0 jwt authorization instead of keyclock this time around

[@nailtagiyev6340]

Cool. Thanks for the course!

[@raghavanaliassaravananm1546]

Lovely. Thank you for the series Sai.

[@ruhuseyn]

I am very excited about this tutorial. Your explanation is awesome. Good luck

[@shrutisharma3469]

One word::- Wow....such an amazing course.

[@hugofernando846]

Thank you man! Very good explanation! Keep going. :D

[@ugveydev]

Course is very good brother I was learning from the old series also was good but this one is really great I think

[@NaTa-qn4yv]

Good. Thanks for the tutorial!

[@darkdragon5307]

finally, a new tutorial. I will skip this until full episodes are downloaded, though

[@user-ql4nt3te6r]

excited for playlist

[@hrsatsangi]

Eagerly waiting for this series thank you Sai for such a great effort Love From AGRA ❤❤

Can we pls connect, From Agra too. Lets build a project together.

thanks bro!

[@BiswajitSamalOdisha]

Thank you

[@karthikr3259]

Thank you for the videos, Could you please also cover Microservices design patterns and principles

[@HaniDaddy]

Wow that's a great tutorial, can you please add frontend frameworks like React or Angular for this series.

[@rubbish9231]

Nice

[@davidontiveros2895]

Appreciate all the new content. Question, how is this different from the current playlist you have ? The one you posted a year ago ? Trying to figure out if I should just start with this one or keep watching the old one.

[@ProgrammingTechie]

This is the more relevant playlist and more detailed, check the pinned comment

[@davidontiveros2895]

@@ProgrammingTechieappreciate it. Didn’t see the comment 🤦🏻‍♂️. Your content is very helpful.

[@tabrezshaikh7705]

Thanks a lot! I was waiting for this. Any idea, by when will all the episodes of this tutorial be released? Also, what is the total watch time of this complete series?

[@ProgrammingTechie]

Hey, it will take 2 more weeks to release the whole course, I don't know the total watch time, but it will be greater than 6 hours

[@szymonnizioek3810]

Very helpful video! I have one question about your model class: why is it anomic (consisting of a setter, getter, such as a value object) instead of being a rich business entity class (which contains some state, behavior, and validations)?

[@ProgrammingTechie]

I want to keep this simple :) , in this tutorial, I am mainly concentrating on the surrounding technologies instead of each individual project.

[@srikarsharma9628]

can this project be developed on a macbook Air..looking at so many software components that were used ?

[@gerardsegismundo8931]

thank you. can you pls do or add aws to it?

[@ProgrammingTechie]

I will not be covering this in this series. Deploying Kubernetes to AWS EKS is first of all not covered in the free tier. You will be charged for the usage of AWS. In my paid course I will be covering deployment to cloud with the deployment to GCP.

[@joelravanely8914]

regarding the paid course, will there be a frontend? like Angular?@@ProgrammingTechie

[@poornima.dpreethi4546]

Why Eureka is used when client side server zookeeper is present

[@youssefzahi3418]

Can you implement oauth2.0 jwt authorization instead of keyclock this time around

[@ProgrammingTechie]

Can you explain more about what you mean ? If you want to use OAuth2 then you have to use any authorization server like Keycloak/Auth0/Okta You cannot implement OAuth2 without it. If you want to just have JWT Authentication and Authorization without using Keycloak, then I have to tell you that's not a standard practice in the real world. JWT auth is used only when you are using monolithic apps.

@ProgrammingTechie Your training is awesome, why cant you make udemy course?

[@anandlshinde]

@PragrammingTechie Thanks for creating this series I followed the same steps for docker. same configuration was added in docker-compose file but still I am facing the below error while executing docker compose up -d command. can anyone guide me here to resolve this issue? Thank in advance! `version` is obsolete" error during connect: this error may indicate that the docker daemon is not running

[@BrainRainGoAway]

is you docker client running in background ?

[@Sebastian-zs8cp]

In 8:06 why you don't take the cloud lib and why u use maven not gradle becous it is faster as maven?

[@ProgrammingTechie]

I don't know if Maven is faster than Gradle, for me I am more used to Maven, and I see no reason to switch to Gradle.

[@mohammedabbutalha2793]

Hi, Am getting AuthenticationFailed for the MongoDB even though I have given the correct entries in the docker-compose.yml and the right connection string in the application.properties. Can you please help me

[@saujan6289]

I am getting the same error, Can't get over it.

[@saujan6289]

I found the problem in my case, I had local instance of mongodb If you have mongodb installed locally uninstall it.

[@azamatshauenbekov6319]

[@ritheasenn]

@@saujan6289 so I need to uninstall the mongodb locally one in my computer and using only the mongodb in docker instead ?

[@anotherOne12342]

Had the same issue with an already running instance from the tutorial before. Either stop the old one, or use another port. (Change docker-compose.yml --> port: - "27018:27017" (Host 27018 mapped to 27017 within docker container port))

hi, your graphic is wrong 3:50 and special your arrows for sync. comm and unsync. comm. it make me confius. sync. comm = and unsync. comm = ->....can you straighten that out?

[@mustafaadel9703]

Can you explain why did you use mongo with the product service ?

[@faixan13]

because product data is usually unstructured means every product can have different attributes as we dont need rigid schema for that or proper relationships.

[@alexanderay2585]

Hello, will you create frontend for this project? thanks

[@ProgrammingTechie]

Frontend is not planned for this series

[@user-dp1xb9pl5x]

where can I get the source code of the course

[@prashlovessamosa]

Sai sir what are the prerequisite to start with this i can build a rest api with Spring Boot but hav no exp with k8s should i learn that first ?

[@ProgrammingTechie]

No need I will start with basics of k8s

[@prashlovessamosa]

[@Coolpratik10]

Which one should i continue sir ji .. The previous one that you posted a year back "Apr 23, 2022 Spring Boot Microservices Full Course" or this one ? @ProgrammingTechie

HI Sir, Is this series is free?? Or we need to take subscription. How many upcoming classes are there??

how ide authomatic write code? do tutor, please)

Nice video. But the font size is very small, and watching on the laptop is very difficult, please increase the font size in future videos.

[@ProgrammingTechie]

I increased the font size in the latest 2 videos, got a new monitor recently that messed up the recording resolution 😔

[@sumanta8504]

@@ProgrammingTechie I used my big monitor to watch the video and the laptop screen for IntelliJ. Normally, I do it the other way around, but I switched because of the font size. Anyway, it's not a big problem when you have great content :)

[@Shopme-ty2wv]

Very good Explanation. when the next part be released?

[@shouryakhujneri5132]

Did Anyone face any issues with integration tests ? while writing the test case for shouldCreateProduct method, it is asking me to typecast it to ResponseAwareMatcher) like this : - .body("id", (ResponseAwareMatcher) Matchers.notNullValue()) .body("name", (ResponseAwareMatcher) Matchers.equalTo("iphone 15")) Can someone please help with this ? @ProgrammingTechie
