Storage for VM and containers

Virtual Machine Storage & Container-Based Storage Solutions

To ensure an organization’s data security and scalability, we provide comprehensive storage management services, including the design and implementation of SAN/NAS/DAS/Backup solutions.

What is Containers?

  • Operating system (OS) virtualization has grown in popularity over the last decade to enable the software to run predictably and well when moved from one server environment to another. But containers provide a way to run these isolated systems on a single server or host OS.

  • Containers sit on top of a physical server and its host OS—for example, Linux or Windows. Each container shares the host OS kernel and, usually, the binaries and libraries, too. Shared components are read-only. Containers are thus exceptionally “light”—they are only megabytes in size and take just seconds to start, versus gigabytes and minutes for a VM.

  • Containers also reduce management overhead. Because they share a common operating system, only a single operating system needs care and feeding for bug fixes, patches, and so on. This concept is similar to what we experience with hypervisor hosts: fewer management points but slightly higher fault domain. In short, containers are lighter weight and more portable than VMs.

What is Virtual Machine (VM)?

  • Virtual machines (VMs) are technology for building virtualized computing environments. They have been around for quite a while and are considered the foundation of the first generation of cloud computing.

  • Simply put, a virtual machine is an emulation of a physical computer. VMs enable teams to run what appear to be multiple machines, with multiple operating systems, on a single computer. VMs interact with physical computers by using lightweight software layers called hypervisors. Hypervisors can separate VMs from one another and allocate processors, memory, and storage among them.

  • VMs are also known as virtual servers, virtual server instances, and virtual private servers.

    • Virtual machines and containers differ in several ways, but the primary difference is that containers provide a way to virtualize an OS so that multiple workloads can run on a single OS instance. With VMs, the hardware is being virtualized to run multiple OS instances. Containers’ speed, agility, and portability make them yet another tool to help streamline software development.
