As per my knowledge these are key upsides of Calico: Network policy model: good tools for network traffic control and access controls based on IP address, ports and protocols and application layer security or mesh traffic control 2.Performance : This network approach delivered excellent performance for workloads in our Kubernetws and Docker environment 3.Simplicity : The best one which I like is this simplicity because of api model which is used to integrate with our orchestration tools 4.Open source 5.Compatibilty: we can use this in various cloud envs, on prem env and data centers

The platform is easy to use but still powerful for all our needs. Any questions I had were quickly and expertly answered by customer support. Great to have them as a manufacturing partner.
