gRPC is a new and modern framework for building scalable, modern and fast API. It is leveraged by many top tech companies such as Google, Square & Netflix and enables programmers to write micro-services in any language they want while keeping the ability to easily create communications between these services. It relies on Protocol Buffers for the transport mechanism and Service Definition language.

About the Author: Udemy
Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.
Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions
What are the prerequisites for enrolling in this course?
The course assumes a basic understanding of programming concepts and familiarity with Java, as it involves setting up Java Gradle projects and implementing APIs in Java. Knowledge of HTTP/2 and basic networking concepts will be beneficial, as these are covered in the context of gRPC API development.
What kind of projects will I build during the course?
Students will engage in hands-on projects such as setting up and implementing various types of gRPC APIs, including Unary, Server Streaming, Client Streaming, and Bi-Directional Streaming APIs. There are also practical exercises like creating a Blog Service using CRUD operations, which include setting up the server and client for operations like CreateBlog, ReadBlog, UpdateBlog, and DeleteBlog.
Who is the target audience for this course?
This course is designed for developers who wish to build scalable and modern APIs using gRPC technology. It is particularly suited for those who want to understand the differences between gRPC and REST, and for programmers interested in multi-language microservices communication, as the course covers language interoperability.
How does this course compare to other API development courses?
While many API development courses focus on REST, this course offers a deep dive into gRPC, covering its unique aspects such as Protocol Buffers, HTTP/2, and various streaming APIs. It also includes hands-on modules on SSL security and language interoperability, providing a comprehensive understanding of gRPC's role in modern API architecture.
What specific tools or platforms are used in this course?
The course utilizes Java with Gradle for project setup, and tools like MongoDB and Robo 3T for database operations. Additionally, the Evans CLI is used for testing CRUD operations. These tools help in demonstrating practical applications of gRPC in building microservices.
What topics are not covered in this course?
The course does not cover basic programming concepts or introduce Java as a language. It also doesn't delve into REST API development beyond comparing it with gRPC. Additionally, while it covers gRPC security aspects, it assumes prior understanding of SSL.
What is the expected time commitment for completing the course?
The course comprises 61 lessons, but the total runtime is not specified. Given the practical exercises and theoretical components, students should expect to dedicate several hours per week over a period of weeks to fully engage with the material and complete the hands-on projects.
