Integrating a full-fledged vRouter alongside the workloads provides CN2 the flexibility to support such as link and node failures. The Contrail controller reports and logs these events where appropriate and reconfigures the vRouter data plane as necessary. Although any single node can contain only

containerized applications within a Kubernetes cluster, that can survive the lifetime of a pod or the node it is running on. SUSE Rancher is a Kubernetes management platform that simplifies the cluster dynamic deployment, allowing you to scale storage and compute resources together or independently, one node at a time as per your requirements. • Shared platform for heterogeneous workloads The platform compute-only nodes. Figure 3. Logical architecture of RKE cluster In this example, each storage-only node includes two Intel Xeon Scalable 12-core processors, 224 GB RAM, and eight 1.92 TB SSDs. From the

all machines are managed as a cluster (or set of clusters, depending on the topology used). Node A logical machine unit (physical or virtual), which is part of a larger cluster on which you can vast cluster running a large number of nodes. When a container fails on a given node, it may be launched on a different node. How do you ensure that all other containers connecting to that failed container monitors the clusters at multiple levels. Heapster is used to aggregate vital metrics, while the kubelet node agent queries cAdvisor to fetch data from containers and provide to Heapster. The performance data
