Virtual container technology options for management, security

Virtual containers are all the rage, but do they live up to the hype? Find out the latest on container management tools and strategies for the best security.


Containers are not just for development and testing. Companies such as Docker, Amazon, Google and Microsoft offer some compelling and full-featured virtual container products aimed specifically at enterprise IT production environments. But are these offerings a sign that containers are ready for enterprise deployments, or are businesses not ready to make the necessary changes to switch to containers?

Use this guide to learn about the current virtual container choices and technologies, proper tools for management, and the level of security achievable for different container options. Not sure what some of the lingo means? Head down to the glossary section to brush up on key container terms.
