Unless you've been hiding under a rock in a datacenter from the last century, chances are you've heard of Docker, the leading software container solution on the market. And if so, you've likely heard of its chief competitor CoreOS as well. Let's see how the two stack up in this comparison.
This is a clash of virtualization titans: one virtual machine, the other a containerization technology. In reality, both are complementary technologies—as hardware virtualization and containerization each have their distinct qualities and can be used in tandem for combinatorial benefits. Let’s take a look at each to find out how they stack up against each other, as well as how the two can be used in tandem for achieving maximum agility.
With the huge growth in virtualization and cloud computing, there has also been a correspondent increase in the average number of virtual machines (VM) that today’s admin has to manage. Manually creating a full VM on today’s virtualizers, like VMWare and Hyper-V, is a real pain because they have to take a snapshot of the entire machine config, and then replicate this to another machine. As you can imagine, VM images eat up a lot of space and time.
