 As organizations embrace microservices with cloud-native applications, it enables them to develop more secure, scalable, resilient cloud-native applications with faster application release cycles. However, these benefits come at a cost with challenges and complexity when it comes to managing, monitoring, testing, and importantly, securing the communication between different microservices that make up the application. Red Hat OpenShift Service Mesh can overcome these challenges by providing OpenShift customers with consistent service networking and a uniform way to secure, connect, manage, and observe their containerized microservices-based applications. It is based on the leading Kubernetes Service Mesh project, Istio. OpenShift Service Mesh also leverages other leading-source projects, such as Kiali and Jager, to provide additional functionality such as an intuitive management interface and powerful monitoring. It also includes troubleshooting of microservices-based distributed systems. OpenShift Service Mesh is included in all Red Hat OpenShift subscriptions.
