Understanding Contrail Networking

Contrail Networking provides dynamic end-to-end networking policy and control for any cloud, any workload, and any deployment, from a single user interface. It translates abstract workflows into specific policies, simplifying the orchestration of virtual overlay connectivity across all environments.

It unifies policy for network automation with seamless integrations for systems such as: Kubernetes, OpenShift, Mesos, OpenStack, VMware, a variety of popular DevOps tools like Ansible, and a variety of Linux operating systems with or without virtualization like KVM and Docker containers.

Contrail Networking is a fundamental building block of Contrail Enterprise Multicloud for enterprises. It manages your data center networking devices, such as QFX Series Switches, Data Center Interconnect (DCI) infrastructures, as well as public cloud gateways, extending the continuous connectivity from your on-premises to private and public clouds.

Contrail Networking reduces the friction of migrating to cloud by providing a virtual networking overlay layer that delivers virtual routing, bridging, and networking services (IPAM, NAT, security, load balancing, VPNs, etc.) over any existing physical or cloud IP network. It also provides multitenant structure and API compatibility with multitenant public clouds like Amazon Web Services (AWS) virtual private clouds (VPCs) for truly unifying policy semantics for hybrid cloud environments.

For service providers, Contrail Networking automates network resource provisioning and orchestration to dynamically create highly scalable virtual networks and to chain a rich set of Juniper Networks or third-party virtualized network functions (VNFs) and physical network functions (PNFs) to form differentiated service chains on demand.

Contrail Networking is also integrated with Contrail Cloud for service providers. It enables you to run high-performance Network Functions Virtualization (NFV) with always-on reliability so that you can deliver innovative services with greater agility.

Contrail Networking is equipped with always-on advanced analytics capabilities to provide deep insights into application and infrastructure performance for better visualization, easier diagnostics, rich reporting, custom application development, and machine automation. It also supports integration with other analytics platforms like Juniper Networks AppFormix and streaming analytics through technologies like Apache Kafka and its API.

Contrail Networking also provides a Graphical User Interface (GUI).This GUI is built entirely using the REST APIs.
