Despite all this there is still a lot of confusion about what exactly

Docker is, what it brings to the table over existing technologies, the reason for its success, and most importantly, why we need it and how it will change the way we develop, build, test and deploy our software applications.

Containers: a simple concept
Docker is, at its core, a successful attempt to standardize the Linux container technology we’ve enjoyed over the past few years. To explain what a software container is, Docker’s marketing team often uses the analogy of a shipping container. But given the profile of SG’s audience, perhaps another analogy is more familiar to all of us: the virtual machine. If we think of the operating system running inside a virtual machine as being “tricked” into thinking it’s running on its own hardware, then the analogy is simple. An application or uae phone number data process running inside a container is also being “tricked” into thinking it’s running on its own operating system. Just as with virtual machines, where the hardware the operating system “sees” may not necessarily be the same as the hardware that exists in reality, a container may “see” a different operating system than the operating system it’s running on. It is worth noting that, although there are similarities between the two, a container solves software bottlenecks, while a virtual machine solves hardware bottlenecks. Both are complementary, not exclusive.
