I wonder If anyone has a hosting/server company which uses Docker rather than traditional virtualization? And what would be the pros/cons of both systems for you?
just read up on docker issue tracker to get a feel or what could go wrong and decide https://github.com/docker/docker/issues At networking level https://github.com/docker/docker/issues?q=is:issue+ispen+label:group/networkingAs DevOps matures enterprises have a need to put critical applications running on Docker Containers into production. Security folks currently have a hard time to decide if their Docker use case is ready to be operationalized. Is it a “go”, a “no go” or do they need to implement additional controls before putting it into operation?
The answer depends on how you define security. If security for you is a measure of segregation capabilities then containers are not quite there yet. If you take a step back and look at the bigger picture and consider the many pockets where security must usually go, then you come to interesting insights!
Applications deployed in containers are more secure than applications deployed on the bare OS
In short, despite the challenges, Gartner believes that one of the biggest benefits of containers is security. Gartner asserts that applications deployed in containers are more secure than applications deployed on the bare OS and, arguably, on a VM. Although containers will not prevent applications from being compromised, they greatly limit the damage of a successful compromise because applications and users are isolated on a per-container basis so that they cannot compromise other containers or the host OS — as long as a kernel privilege escalation vulnerability does not exist on the host OS.
