What CNI solutions have you used in your Kubernetes projects?

In Kubernetes projects, various CNI (Container Network Interface) solutions are often used to organize network interaction between pods. Here are some popular options:

• Calico — provides network policy and routing, suitable for large clusters with high security requirements.
• Flannel — a simple overlay network solution, often used in small to medium clusters.
• Weave Net — supports automatic network configuration and traffic encryption.
• Cilium — uses eBPF for high performance and advanced network security features.

The choice depends on project requirements: scalability, security, performance, and ease of configuration.
