Usage of Virtual Appliances in Microsoft Azure

When you place your resources in the cloud utilizing Microsoft as a provider of public cloud, your network which is situated in the cloud can be termed as a n Azure virtual network (Vnet). Your virtual network can be configured in a similar way as your internal on-premises network; i.e,

Top Ten Ways Not To Sink the Kubernetes Ship

Linux Academy

Kubernetes nodes rely on underlying virtual servers for both the master control plane and for worker nodes. It is important to use security tooling such as OpenSCAP, the open source version of the Security Content Automation Protocol, to harden virtual machine images prior to their deployment in virtual private clouds. Vulnerabilities at the operating system level may be exploited by rogue container workloads if not hardened.
