What is Docker?
  • There are two ways of looking at Docker. The
    first approach involves seeing Docker containers
    as really lightweight virtual machines, while the
    second approach is to see Docker as a software
    packaging and delivery platform. This latter
    approach has proven a lot more helpful to human
    developers and resulted in widespread adoption of
    the technology.

An Overview of Docker Containers
  • Traditionally, cloud service providers used
    virtual machines to isolate running applications
    from one another.
  • A hypervisor, or host operating system, provides
    virtual CPU, memory and other resources to many
    guest operating systems.
  • Each guest OS works as if it is running on an
    actual physical hardware and it is, ideally,
    unaware of other guests running on the same
    physical server.

  • However there are several problems with
    virtualization. First, the provisioning of
    resources takes time.
  • Each virtual disk image is large and bulky and
    getting a VM ready for use can take up to a
    minute.
  • Second and a more important issue system
    resources are used inefficiently.
  • OS kernels are control freaks that want to manage
    everything thats supposedly available to them.
    So when a guest OS thinks 2GB of memory is
    available to it, it takes control of that memory
    even if the applications running on that OS uses
    only half of it.

  • On the other hand, when we run containerized
    applications, we virtualize the operating system
    itself, not the hardware.
  • Now, instead of providing virtual hardware to a
    VM, you provide a virtual OS to your application.
  • You can run multiple applications and impose
    limitations on their resource utilization if you
    want, and each application will run oblivious to
    the hundreds of other containers it is running
    alongside.
