A multi-cloud service networking platform to connect and secure services across any runtime platform and public or private cloud. Real-time health and location information of all services. Progressive delivery and zero trust security with less overhead. Receive peace of mind that all HCP connections are secured out of the box. Gain insight into service health and performance metrics with built-in visualization directly in the Consul UI or by exporting metrics to a third-party solution. Many modern applications have migrated towards decentralized architectures as opposed to traditional monolithic architectures. This is especially true with microservices. Since applications are composed of many inter-dependent services, there's a need to have a topological view of the services and their dependencies. Furthermore, there is a desire to have insight into health and performance metrics for the different services.
