Event-Driven Microservices: Spring Boot, Kafka and Elastic (Udemy.com)

One of the best courses available online on java microservices . What a course , i am truly spellbound. Top of that , instructor is readily replying back for any issue ,this is what its make it great course. I am truly enjoying it. One has to go video by video carefully and try to do in their own local system hands on, and rest assured its worth it.

This Course is a comprehensive and hands-on experience for Spring Boot developers looking to dive into event-driven microservices with a focus on Kafka, Elasticsearch, and Event-Driven Microservices. The incorporation of various technologies such as Kafka Streams, CQRS, and Twitter-to-Kafka event streaming adds depth to the learning experience. The provided agenda and exercises are well-structured, covering key aspects of the technology stack. The Course Agenda is practical and contributes to a deeper understanding of real-world challenges in Microservices development. This Course is not only a learning resource but also a practical guide for building and deploying such systems in development and production environment. Overall, this Course is a fantastic resource for developers interested in building event-driven Microservices with Spring Boot, Kafka, and Elasticsearch. Thank you, Ali Gelenler for this super practical, interesting and challenging Course!

- This course is a great example of creating a product consisting of a few microservices. - I spent 28 hours (breaks included) to finish the course. I often paused the video, browsed through the code, and tried changing small things. - This course looked like one of the most technical ones regarding microservices/event-driven architecture. What you will not learn: - How to efficiently separate the app into multiple repositories - Independent deployment of particular services - Services versioning - Writing tests (the tutor does not write any tests for time reasons) Recommendations: - The most issues were with setting up a Keycloak connected to a local Postgres database. Next time I would go through this section very briefly and try to disable security in all microservices. - Do not try to use Twitter production data but use the mocked option. It works well enough, and you don't need to wait for Twitter API key approval (mine wasn't approved even after two weeks of waiting). - Downloading the resources in zip files isn't very convenient. It would be better to have one public repo and just switch the tag/branch for every lesson.

The course's content is absolutely good content and very much the best practices. One thing to note before taking the course is if you want to "do by learning" I do not think you can with this course because it is heavily loaded with content and the lecturer goes through most of the content very fast so you would need to play it at 0.7x speed to make it through. Note that the course is around 13-14 hours but trust me it will take more than 40-50 hours to complete, at least that is what worked for me. Hours of writing code, debugging, and last but definitely not least loads of learning throughout the course. Also the lecturer, Ali is very helpful and answers within 24-to-48 hours if you ask a question. The only reason I am not giving the course a 5-star rating is because it is pretty fast paced even though I do not know the reason because this course could've been easily 25 hours if things would go a bit more slower but other than that the course is top notch!!

The project example is ammaaazing, really cool, the way Ali setting the project itself is also really cool, seems like a really best practice in Spring world. In some concept, the explanation is good, but in some other concept like kafka, the explanation is still lacking, but it's fine. The IDE though, is still often not zoomed in, so it's hard to read the code, but everything else is great!

Extremely difficult course to follow .The trainer should slow down at first,the configuration server and all the refactoring cannot be understood in a single flow.No doubt the instructor is extremely talented but in between lectures i cannot understand much of the workflow .There are many annotation and many configuration changes and much more refactoring but its difficult .I have completed the couse but like the keycloak configuration ,clients,mapping,credentials,roles and authorize all these things take huge time and also the outh2 and openId connect takes time.I can get a feel of the code but the workflow seems really difficult to be comprehended.I did not any language problem using captions

The course is difficult to follow, it is the course that took me longer to finish based on the total hour (11 hours -> 1 month of my time), and I have attended over 30 courses on Udemy. I can say the content is great, so I have still found time to finish it and create a better repository on GitHub for those who need help, there is the latest version and to run everything you just need to follow the README:: https://github.com/Armando1514/Event-Driven-Microservices Due to the fact that the security part is almost copy and paste, I have added an explanation of what is happening behind the scene: https://github.com/Armando1514/Event-Driven-Microservices/blob/main/doc/SECURITY.md A star is appreciated.

I have purchased many bestselling courses related to Spring on this platform, but this course is, by far, the best investment I have ever made. I'm amazed at the amount of knowledge I've accumulated since I started it. IMPORTANT: This course focuses primarily on how to create a complex, real-world application to help people in their day-to-day work. It assumes that you have experience as a Spring developer. It uses modern and widely used technologies and teaches you how to put them together to create an application that has the same robustness as what is done in the industry. ㅤ For beginners with minimal knowledge: This course is difficult, but is the best experience you can have if you take it as a guide, as it will show you precisely what you need to learn to create a complete application (see my advice below*). For others: just take it. It's a gold mine. Not only will you improve your skills, but you will also be up to date as the teacher is constantly adding updates on a dedicated section to migrate the whole app to the latest version. ㅤ The final built project is incredibly (!) dense. It's so dense that it can be used as an inspiration to build any personal project you want. That's what makes this course unique: it doesn't teach you through snippets like the vast majority of courses. It's pure practice, like an internship in a real company. Also, sometimes you may find some parts difficult to follow, too fast, or feel the need to research additional information/courses, but at the end of the day, your efforts will be rewarded. It is important to understand that this course is not a course that teaches you every aspect of every technology used (otherwise it would be a 100 hour course), but rather a course that allows you to learn best practices and shows you how an experienced developer builds a complete and robust application, so you can replicate the steps. ㅤ *Advice to beginners: I started this course with minimal knowledge of Spring, gathered through a few best-selling courses on Udemy. If you take this course, keep in mind that its main objective is to show you the complete process of how a professional developer builds a complete and complex application, with the guarantee that the implementation will be done correctly and be up-to-date. So whenever you feel lost, pause the videos, search for external resources/courses, then come back. This is what I did, and the progress I made was phenomenal because I knew exactly what to learn as I moved forward. I strongly advise you to take it as a guide, so you can see what a real application looks like (unlike most demos that can be found on the internet, that are just snippets).

This was one of the best courses I have ever attended and here is why. It contains really good coverage of Spring framework and it's security in addition of SSO (single sign-on) system using OAuth2. Also, this course covers Kafka and Elasticsearch so you will learn how to handle and transform streams of data and understand processes happening underneath the hood. You will also learn how to use Docker to containerize all the microservices you will be building along with Ali. On top of everything, you will also create graphs and metrics to monitor your services, and aggregate logs with Spring technologies. There is a lot of work here, but it all pays of at the end. This is also an invaluable source of knowledge material for everyone studying microservice architecture, plus I really have to recommend Ali as knowledgeable, responsive and responsible tutor. I have recommended this course to my work collagues. Best regards, Filip P.S. Follow the exact same versions of dependencies as given in the course videos, and update later, to save yourselves a lot of trouble :) Also, if you find videos to fast, just set them to 0.75x speed, it will be perfect :)

It's impressive the work that the instructor have achieved, and it's so awesome to learn about driven event systems even though is super hard to follow the whole tutorial because of the complexity. In my personal opinion I would recommend the instructor the next changes: 1.- Avoid spring security or move it to the last chapters. 2.- Try to void Avro till the last chapters. 3.- Avoid lombok because cause instability in eclipse newest versions. You really should to break this training in two courses at least with beginner and advance. I have seen some bad reviews and I totally understand the frustration trying to understand this topics without the necessary experience
