is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation often referred to as microservices, wherein a large application is split into small independent services that communicate with each other via APIs using lightweight protocols like HTTP. Microservices applications application traffic for security purposes as the port is utilized for a wide range of messages across services. An additional challenge is the ability to provide accurate visibility as traditional systems are
