Best Container Networking Software

Researched and written by Adam Crivello

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

User Sentiment

Users like the product's high throughput, low latency, ability to handle large numbers of concurrent connections, advanced features like SSL termination, health checks, session persistence, and its flexibility to fit into many environments such as on-prem servers, VMs, containers, and Kubernetes setups. Reviewers noted that the configuration can be complex for beginners, advanced setups can become hard to read and debug, and teams that want a polished built-in GUI or simpler certificate automation may find it less convenient, and it requires careful tuning to avoid performance bottlenecks or misconfigurations.
