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.
Picking the right container
A number of companies provide container services: Amazon Web Services (AWS), Microsoft's Azure Container, Google Container Engine and Kubernetes, Docker -- the list goes on. The stories below will give you a better idea about the choice between bare metal and VMs for Docker deployment, migration technologies, a way to try out Linux containers and more.
Understand the critical differences in how containers and VMs work in public, private and hybrid cloud environments before jumping on either technology. Continue Reading

4Virtual container security-
Are they or are they not secure?
Container security levels vary, depending on the type of virtual container and how the IT team implements containerization. Some experts say that Docker is less secure than CoreOS, while others tout its security options.
Flexibility is containerization's greatest strength over server virtualization, but it can leave IT workloads more open to attacks without proper management of daemon control access. Continue Reading
