Azure Container Service (ACS) allows for the creation and management of a cluster of virtual machines that act as container hosts, together with other "master" machines for orchestrating application containers.
The ACS preview was just one piece of Azure news today.
Microsoft also kicked off the public preview of Azure Security Center on December 2. Azure Security Center, which Microsoft officials unveiled a couple weeks ago, allows users to monitor the security state of their Azure resources and control cloud security with policies for various configurations. The Azure Security Center also alerts users to threats detected using Microsoft's analytics and threat-monitoring systems.
