Containers are here. And it doesn’t mater whether or not containers are a transitional technology (they are, as our JP Morgenthal covered in Containers are designed for an antiquate application architecture) until all applications are designed for cloud and web-scale, containers will be part of the cloud and virtualization scene. Right now, containers are white hot. And as you’ve seen here in the past month, containerization was an editorial focus for us throughout March.
To give you an idea of how popular containers are right now, consider…
Why would you ever put Docker in dev and test and not take it through to production? It absolutely defeats the purpose of Docker, and you would be deploying a completely different stack than you test.
Docker containers still have security issues… this is the reason why it’s not ready for productions in many cases, in some cases you can use use a workaround and host them inside a VM to solve the security issues partially, but in this case you lose the original promise of density and flexibility benefits.
George, thanks for the article. This topic is really important for the IT industry these days. I would recommend to take a look at the another option about secure containers. http://blog.odin.com/serviceprovider/2014/12/12/parallels-containers-and-the-dockerrocket-conundrum. The industry needs a better solution for containers isolation and security compare to the containers virtualization provided by Docker by default. And this solution exists already and used by many hosting service providers during the last 14 years. It should be just adapted for enterprises by somebody big in the enterprise world, from my point of view.
