Before moving workloads to Docker, you need to evaluate the Docker-specific security risks and make sure you can handle them. Yet Docker also creates new security challenges - such as the difficulty of monitoring so many moving pieces within a dynamic, large-scale Docker environment. Containers also make it easy to break your application into small parts, so that if one part is compromised, the rest is not necessarily affected. Docker can improve security in some ways by isolating applications from the host system and from each other. (You could also run a Web interface, which is easier to do, but then you have to run a Web server and your interface options will still be limited.) Practically speaking, Docker is not a good solution for applications that require rich interfaces. There are some tricks you can use (such as X11 forwarding) to make it possible to run a a graphical interface inside a Docker container, but this is clunky. Docker was designed as a solution for hosting applications that run on the command line.
#DOCKER FOR MAC LINUX CONTAINERS VS NATIVE CONTAINER PERFORMANCE COMPARISON WINDOWS#
In highly heterogeneous environments composed of both both Windows and Linux servers, this makes Docker less attractive. Virtual machines are not subject to this limitation. An application designed to run in a Docker container on Windows can’t run on Linux, and vice versa. The only way to get true bare-metal speed from an application is to run it directly on a bare-metal server, without using containers or virtual machines. Docker containers have less overhead than virtual machines. Run applications as fast as a bare-metal server.Here are examples of things Docker can’t do or can’t do well: Things Docker Can’t Do Wellīut that doesn’t mean that Docker containers are the perfect solution for every type of workload.
If you really want to understand how Docker is impacting the channel, you have to understand its limitations.ĭocker containers have become massively popular over the past several years because they start faster, scale more easily and consume fewer resources than virtual machines. But Docker containers are not a cure-all.
