This course is designed for individuals with a foundational knowledge of command-line interfaces and a good understanding of software development and deployment concepts.

We also recommend our Microservices Seminar as all aspects of the course are around the terminology and practices in MSA.

Familiarity with the basics of networking and cloud computing will enhance the learning experience
