Kubernetes works on the principle of assigning IP addresses to pods, called as “IP-per-pod” model. The IPAM (IP address management) task is left to third party solutions. Some of these solutions include Docker networking, Flannel, IPvlan, contive, OpenVswitch, GCE and others. The Kubernetes architecture consists of master node, replication controller..
First question that comes to mind is whether SDN and NFV are same or different or related technologies? SDN and NFV are independent technologies. SDN creates a separate management plane which sits a floor above the traditional control plane so as to get wider view of the network and orchestrate using network protocols like OpenFlow. So, with the SDN approach
Docker is a great technology which simplifies the development and deployment of distributed applications. While building dockerized applications, security at various points needs to be considered. Due to lack of CPU/Hypervisor, Docker security is fully implemented in Software. Let us look at all prominent security aspects of kernel and container applications
