Overview NSX ALB (previously known as Avi) offers rich capabilities for L4-L7 load balancing across different clouds and for different workloads. NSX ALB can be configured to L4-L7 load balance across containers workloads by means of deploying an ingress controller which is known as AKO (Avi Kubernetes Operator) and leverage the standard Ingress API in […]

Key day two operations for an enterprise running Tanzu and/or Kubernetes clusters would typically include automated discovery, monitoring and troubleshooting of management and workload clusters. With the radical and exponential increase in the amount of traffic, interconnected flows and relationships between containerised workloads, the need of powerful and insightful monitoring tools is greater than ever. […]

In this blog post we will be exploring how vRealize Network Insight can be used to monitor Tanzu and kubernetes clusters running NSX Container Plugin (NCP) as CNI. NCP is used in Supervisor Clusters deployed by Workload Management services (WCP) in vSphere and TKGi and can also be used in Openshift and upstream kubernetes. Running […]

In this blog post we will be exploring how vRealize Network Insight can be used for Day0 and Day2 kubernetes operations. Using Network Insight we can gain insights into containers traffic, security requirements, utilisation and capacity planning. Lab Inventory For software versions I used the following: VMware ESXi 7.0.2.17867351 vCenter server version 7.0U3 NSX-T 3.2.0.1 […]

In part two in this blog post series, we will be integrating our kubernetes cluster which is running Antrea as CNI with NSX and will be using NSX to configure centralised security policies for container workloads running on our kubernetes cluster. Lab Inventory For software versions I used the following: VMware ESXi 7.0.2.17867351 vCenter server […]

Overview In this two parts blog post I am going to demonstrate how to setup kubernetes clusters using VMware Antrea CNI (Container Network Interface) and using NSX 3.2.x as centralised security policy manager for pods workloads running on a kubernetes cluster. In part one, I am going to introduce to fundamentals of kubernetes and kubernetes […]
