This article mainly introduces "Spring Cloud micro-service security case analysis". In daily operation, I believe many people have doubts about Spring Cloud micro-service security case analysis. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "Spring Cloud micro-service security case analysis". Next, please follow the editor to study!

Using the popular micro-service architecture development, application access security will face more and more complex challenges, especially the three major issues that developers are most concerned about: authentication and authorization, usability and visualization. This course starts with simple API security, transitions to complex micro-service scenarios, solves the pain points of the above three problems, and gives corresponding solutions combined with practice. Help you form a systematic thinking on security issues, and develop a complete set of security programs that can be landed in small and medium-sized companies.

Suitable for the crowd

Hope to form a systematic understanding of micro-service security.
