Calico is a versatile networking and security solution that features a plugable dataplane architecture, supporting various technologies including Iptables, eBPF, Host Network Service (HNS for Windows), and Vector Packet Processing (VPP) for containers, virtual machines, and bare-metal workloads. Datadog's Calico integration provides granular detail into traffic between Kubernetes resources and other workloads, enabling users to ensure that their network policies are properly filtering traffic. The integration allows users to track network policies, restrict traffic to host endpoints and workload endpoints, monitor errors in iptables and ipsets, leverage Datadog's Kubernetes integration to get rich context around Calico performance, and monitor dataplane and ipsets logs. By using the integration, users can prevent connectivity issues from disrupting their end-user experience, secure their workloads from malicious actors when sensitive data has been compromised, and troubleshoot issues more effectively.
