Assimilation System Management Suite

The Assimilation Suite discovers systems, services, network connections, configuration and dependencies, IP and MAC addresses. This all goes into a continually updated graph-based configuration management database (CMDB). This is then compared and scored against best practices, services and servers are monitored - all with near-zero configuration - in a way that scales to hundreds of thousands of servers. It also provides visualization tools, APIs for sending alerts to humans and other systems, and a variety of canned reports (queries) to aid in securing and managing systems, hooking into ChatOps, and creating plans for triaging your security issues

Docker

Docker uses LXC to create and manage native, sandboxed virtual containers. LXC containers acts like a separate OSes, can install their own packages without affecting anything else, and overall have almost the same flexibility of VMs but without any of the virtualization overhead! Docker adds a ton of features, like an elegant configuration file that automates many things (like port forwarding, disk/directory mounting, networking, etc), a way to create and share readymade images that can be distributed as appliances, etc.
