  • Publication number: 20240414148
    Abstract: This disclosure relates to a context enforcement system that efficiently and securely protects tenant context information that travels across microservices in a multi-tenant distributed cloud computing system and protects against data leaks that often occur in conventional microservice management systems. For example, the context enforcement system ensures secure external and internal communications and context isolation by providing various shared library functions to microservices of a multi-tenant distributed cloud computing system. Additionally, the shared library provided by the context enforcement system improves the efficiency of the multi-tenant distributed cloud computing system by allowing microservices to focus on target operations rather than also maintaining and performing additional redundant functions.
