Adapting the network for the rise of containers
They say necessity is the mother of invention. That statement has been true in networking for decades now, as many of the innovations in the network have been driven by changes in compute.For example, Ethernet became the de facto standard to consolidate all of the various LAN protocols that once existed. Another example is the virtual switch. That was invented to solve the hair pinning problem associated with moving traffic between two virtual machines on the same host.+ Also on Network World: Which is cheaper: Containers or virtual machines? + There’s another major compute shift going on that will drive the need for network evolution, and that’s the rise of containers. If you’re not familiar with containers, think of them as a lightweight runtime environment that includes an application and all of its dependencies, including configuration files, binaries and libraries. Containers are similar to virtual machines except they share a single operating system and kernel, so it’s much lighter weight. A VM can be a few to tens of gigabytes in size,where a container is likely to be just a few megabytes.To read this article in full or to leave a comment, please click here
