Customers who uses NSX day-in, day-out would like to have a point-in time restore functionality of DFW firewall rules. Many customer have a large footprints in VMC and make changes to DFW quite often. This feature was missing for long time and we could see its included in recent versions . Let's see how DFW configuration roll back works  NSX DFW configuration has versioning, and it is stored in the NSX Manager.  Every time when someone update DFW configuration, NSX creates one more version but keep storing the previous ones. You can rollback for previous config but reapplying it once again.  You can find the options under Networking & Security tab , > Security > Distributed Firewall .

In this post we see the options to deploy the Virtual Container Hosts ( VCH) Ref:  https://github.com/rdjagadeesh/vic_homelab/ The previous post talks about vSphere Integrated Containers and their benefits. The VIC offers a robust solution that enables the vSphere environment to quickly get containers up and running in their current vSphere infrastructure. This environment can be useful for migrating current apps to containers or for in-house development. Architecture In a traditional container environment, containers run as threads within the container host. vSphere Integrated Containers leverage the native constructs of vSphere for provisioning container-based applications into its own container running its own very minimal Linux kernel with just enough code to run a Docker image, thus preventing any issue with containers being accessed from other containers by pushing isolation of the container down to the hypervisor layer that is much better at handling this type of isolat

What is VIC: VIC - vSphere Integrated Containers enable IT, teams, to seamlessly run traditional workloads and container workloads side-by-side on existing vSphere infrastructure. The solution is delivered in the form of an appliance just like any other VMware mgmt solution. The appliance comprises of,  vSphere Integrated Containers Engine , a container runtime for vSphere that allows you to provision containers as virtual machines, offering the same security and functionality of virtual machines in VMware ESXi™ hosts or vCenter Server® instances. vSphere Integrated Containers Plug-In for vSphere Client , that provides information about your vSphere Integrated Containers set up and allows you to deploy virtual container hosts directly from the vSphere Client. vSphere Integrated Containers Registry (Harbor) , an enterprise-class container registry server that stores and distributes container images. vSphere Integrated Containers Registry extends the Docker Distri
