Deployment Speed/Agility – Docker containers house the minimal requirements for running the application, enabling quick and lightweight deployment.Meanwhile, the Docker Enterprise business was acquired by Mirantis, the Kubernetes As A Service provider.įor both developers and operators, Docker offers the following high-level benefits, among others: Now on version 19.x, Docker now offers native support for Window, streamlining the management of Docker hosts and containers on Windows development machines. In the 0.9 release, Docker replaced LXC with its own libcontainer library written in Go, allowing for broader native support for different vendors. By using Linux kernel features such as namespacing and control groups to create containers on top of the host OS, application deployment can be automated and streamlined from development all the way to production. Containers, built from container images, make it possible to bundle an application up with all the required libraries, dependencies, and resources for easy deployment. Clearly-for DevOps and CI/CD initiatives-application portability and consistency are crucial needs that Docker fulfills quite nicely. The Docker project’s main intent is to allow developers to create, deploy, and run applications easier through the use of containers. Increasingly, enterprises are also embracing Docker as a potential VMware disrupter, but as we shall soon see- it doesn’t compete directly with VMware, despite taking the virtualization space by storm. Though an early virtualization pioneer, VMware is not the only show in town anymore: Microsoft Hyper-V, Citrix XenServer, and Oracle VirtualBox are also popular hypervisor technologies. Console operating system/service console.Once installed, it creates and runs its own microkernel consisting of 3 interfaces: ESXi runs directly on bare-metal server hardware-no pre-existing underlying operating system is required.

Hypervisors allow for multiple operating systems to live on a single host with their own set of dedicated resources, so each guest OS appears to have CPU, memory, and other system resources dedicated to its own use. The suite functions as a cloud computing virtualization OS of sorts, proving a virtual operating platform to guest operating systems such as Windows, *nix, and so forth.Īt the heart of the vSphere suite is ESXi: the main hypervisor technology that makes hardware virtualization possible. vSphere is VMware’s flagship virtualization suite consisting of a myriad of tools and services such as ESXi, vCenter Server, vSphere Client, VMFS, SDKs and more. This industry-leading virtualization software provider needs little introduction, as its products and solutions have paved the way for a generation of virtualization technologies.
