However, in a typical enterprise-grade microservices application, hundreds of microservices may need to interact securely with each other. Kubernetes serves as an excellent platform for hosting and orchestrating microservices. Nevertheless, the default communication between microservices is insecure, as they typically use plaintext HTTP. This may not meet your security requirements. To apply the same security principles to microservices as you would to a traditional enterprise monolith, you must ensure the following:
