The platform dynamically packages it into an image, runs the image in a container, and (if needed) instantiates the underlying host OS and VM and the hardware required to run them."

A worm replicates through the network while a virus replicates, not necessarily to spread through the network.

Multiple policies, no policy reconciliation tools: Sequential traffic analysis (stateful inspection, application control, intrusion prevention system (IPS), anti-malware, etc.) in traditional data center security solutions requires a corresponding security policy or profile, often using multiple management tools. The result is that your security policies become convoluted as you build and manage a firewall policy with source, destination, user, port, and action; an application control policy with similar rules; and any other threat prevention rules required. Multiple security policies that mix positive (firewall) and negative (application control, IPS, and anti-malware) control models can cause security holes by missing traffic and/or not identifying
