Best Container Networking Software

Container networking software creates a virtualized, defined network to facilitate container-to-container connectivity. These internally virtualized networks allow communication and integration between containers or applications powered by container sets. The networks create isolated regions to allow multiple containers to communicate with the same network independently. Companies utilize these solutions for increased scalability and data accessibility of applications. They provide a higher level of security and increased capability for service discovery, essentially powering the microservices industry through linked container applications. Container networking software can increase the functionality of container management software and container orchestration software solutions by connecting designated applications.

To qualify for inclusion in the Container Networking category, a product must:

  • Create isolated networks for container instances
  • Connect containers through designated networks
  • Provide security layers for application networks
  • Allow privileged external connectivity
  • Allow for IP address management

    NSX enables the creation of entire networks in software and embeds them in the hypervisor layer, abstracted from the underlying physical hardware.

    Big Cloud Fabric solution enables rapid innovation, ease of provisioning and management, while reducing overall costs.

    Canal is a community-driven initiative that aims to allow users to easily deploy Calico and flannel networking together as a unified networking solution - combining Calico’s industry-leading network policy enforcement with the rich superset of Calico and flannel overlay and non-overlay network connectivity options. Canal represents the best-of-breed policy-based networking solution for cloud native applications, supporting any orchestrator that support the CNI network plugin API (including Kubernetes, Mesos, and others).

    Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag).

    Warden manages isolated, ephemeral, and resource-controlled environments. The primary goal of Warden is to provide a simple API for managing isolated environments. These isolated environments, or containers, can be limited in terms of CPU usage, memory usage, disk usage, and network access. The only currently supported OS is Linux.

    Cumulus Networks unlocks the network stack so you do not have to rely on proprietary vendors. Build a network based on your needs and your budget, and scale with ease using a web-scale architecture. Cumulus Linux is a powerful open network operating system that allows you to automate, customize and scale using web-scale principles like the world's largest data centers. It accelerates networking functions on over 50 switch models (1G, 10G, 25G, 40G and 100G) from 9 different OEMs with your choice of optics and two silicons. Cumulus Linux was built for automation, scalability and flexibility, allowing you to build a data center network that ideally suits your business needs.

    Contiv unifies containers, VMs, and bare metal with a single networking fabric, allowing container networks to be addressable from VM and bare-metal networks.
