In contrast, containers share the host hardware’s OS instead of creating a new version. The application’s libraries and dependenciesĪ version of the hardware’s OS (the guest OS) to run the application Traditionally, virtualization creates a virtual version of the physical machine, including: The main difference between the two lies in the virtualization process. But VMs and containers have many distinguishing features. Containers are often confused with virtual machines because they serve similar purposes. When researching virtual machines, you will likely encounter the term container. What is the difference between virtual machines and containers? You can use a virtual machine to simulate the previous OS and run the old application there. ![]() Since the application hasn’t been updated with your phone, it may no longer be compatible with your phone’s current operating system (OS). It hasn’t released an update in a few years, but your phone has updated several times since then. Suppose you have an old application on your phone. Running programs with incompatible hardware. The iCloud stores a virtual version of the phone, allowing users to transport their existing data onto a new device in the event of theft or damage.ĥ. For example, iPhone users regularly back up their data by syncing their devices with iCloud. This replication ensures that if the system is compromised, another version exists to replace it. You can use a virtual machine to replicate a system in a cloud environment. Instead of spreading to the rest of the infrastructure, a VM contains the malware for study.Ĥ. VMs enable malware researchers to test malicious programs in separate environments. Isolation allows developers to test software without impacting the rest of the system.ģ. These environments are useful because they’re isolated from the surrounding infrastructure. You can use virtual machines to create fully functional software development environments. Examples of cloud computing include Dropbox, Salesforce, and Google Drive.Ģ. Then, cloud computing distributes those virtualized resources via the internet. Virtualization technology creates virtual resources from physical hardware. Many applications for this technology exist. What are VMs used for?Ĭreating a simulated version of a computer system makes it possible to separate hardware resources from their physical infrastructure. With VM software, you can run programs and store data without using hardware. With VR, you can explore a new environment without leaving home. Instead of imitating video game functions, virtual machine software emulates computer system functions. Still, we can perform real-world functions in VR, such as exploring and interacting with objects. VR isn’t a physical space it’s a virtual imitation. ![]() It’s similar to how virtual reality (VR) environments replicate the real world. It’s a file that replicates the computing environment of a physical machine. What is a virtual machine (VM)?Ī virtual machine is not a physical machine. The following article examines the role virtual machines play in this process and how you can use them. Virtualization uses specialized software that can mimic hardware functionalities. A simple way to conceptualize virtualization is to think of it as software pretending to be hardware. Virtualization is the creation of a virtual version of something, like a storage device.
