Course Description

This is the most complete and high-performance gRPC course available for Java and Spring Boot developers. You will move far beyond simple Request/Response to master the advanced architecture, scaling, security, and low-latency techniques required for modern cloud-native systems.

If you are serious about becoming an Advanced Microservice Architect, this course is your blueprint.

What You Will Master: Core Skills & Performance

This curriculum is designed to teach production-grade gRPC by focusing on the unique and complex challenges of distributed systems:

  • Mastering All Four Streaming Patterns: Deep dive into Unary, Server Streaming, Client Streaming, and BiDirectional Flow. Learn to implement Flow Control and build interactive, real-time applications (including a hands-on game assignment).

  • Performance & Tuning: Optimize client connectivity with Channel Management and Client-Side Load Balancing. Understand server-side performance tuning through Netty Configuration.

  • Robust Architecture: Implement essential defensive coding practices, including Input Validation, full gRPC Error Handling and Deadline Management to guarantee reliability and prevent service outages.

  • Advanced Call Pipeline Control: Integrate Interceptors (Client & Server) to implement cross-cutting concerns like custom API Key Validation, dynamic Deadline Overrides, and Compression.

  • Enterprise Integration: Seamlessly integrate gRPC and all its advanced features into the Spring Boot ecosystem, building a complete service layer ready for deployment.

By the end of this course, you will have the knowledge to design, implement, and deploy high-performance, low-latency microservices that leverage the full power of gRPC, setting you apart as an expert in distributed systems architecture.

The course is easy to understand and comprehend, the explanations are good and clear. Unfortunately, the Spring stuff seems outdated (which was one of the reasons that I bought this course), because grpc support ist now part of rping boot 4 with package ("org.springframework.grpc:spring-grpc-spring-boot-starter").

By Trung Nguyen on 12/26/2025

Thanks, Vinoth, for an amazing journey on gRPC. The course content was really good, the final project was very real. The live coding was good but at the same time it also took students more time to go thru the videos. I suggested that you have the code ready for the videos so you can go thru it quickly. Again, thanks for the amazing journey.

i started the course and remember the voice that he is Vinoth selvaraj he is best,comprehensive , end to end what he teaches. extremerly like every course which he teaches

I was a complete beginner in gRPC, and this course helped me build a solid foundation. The instructor explained each concept clearly and used practical examples that made everything easy to follow. The hands-on approach really helped me gain confidence. Great learning experience overall!

Thanks, Vinoth Selvaraj, for providing great information on gRPC with Spring Boot. The content was great but there were a few time Vinoth was talking too fast that it's hard for me to understand. For this reason I gave a 3.5-star but I consider Spring Boot section was a bonus and so I gave 4-star on my final rating.

Great course on gRPC. Excellent explanation and with many examples. The course covers all the basic topics and goes in depth on many aspects. I reccommend it. I would have liked to see an example of gRPC communication between dockerized microservices to see the part of integration with a service discovery (Consul or others).

I have a case study, which I need to finish in 4 weeks and I have an urgent need to learn gRPC. When I bought this course, my expectations are very low tbh. Because most of the time, courses I bought in Udemy was total crap(no offence to good teachers). But this one is above my expectations, so detailed and he tries to give whatever he knows. Maybe some people may doubts like me or maybe even because of accent issues but trust me, its very understandable. I don't like to write reviews, but I think this guy deserves support from a developer that he just helped.

One of the best courses on grpc. Loved the teaching style (though slow, watching at 1.25x solved that problem) Only feedback: - Breaking the lessons to too small has a problem since for the next section/chapter udemy takes considerable amount of time (10-40 s - depending on network speed) and it is a little disturbing

By Mohan Kamaraj on 1/26/2021

This is one of the best course i have gone through in recent times, the instructor showed the proper examples on every concept he was trying to teach. In fact the hands on examples are really helpful and the same can be referred or used in real time applications. I would recommend this course if anyone wants to learn GRPC.

By Shanky Kalra on 11/21/2020

The joy is unprecedented when you start creating or developing your own APIs because you have always tested the developed APIs as a Tester. Thanks to Vinoth Selvaraj for introducing us to gRPC Based Architecture via his course. Undoubtedly, it turns out to be great learning in terms of 'Microservice Architecture' from a developer standpoint.
