Containers and virtual machines can help improve operational efficiency by allowing multiple programs to run concurrently on a single server and keeping those resources separate. This allows for more efficient usage of the system’s resources, as well as high stability through the preservation of state which would otherwise be lost when shutting down or rebooting.
Virtual machines isolate an entire operating system and the resources it requires to function.
Containers isolate an application and its dependencies from other applications running on a host system, allowing for streamlined distribution of applications across systems without conflicts or requiring multiple versions of an Operating System. This allows for greater portability across different environments, where any one program might be required to run in several different places.
Virtual Machines (VMs) are very useful when it comes to protecting your data and making sure that the different programs running on one computer do not interfere with each other. With a VM, you can have an entire operating system — Windows, macOS, or Linux — running within a window on your computer.
Virtual Machines are very useful for testing purposes, but they are also great when you want to get out of the house and work somewhere else without losing access to your programs or data, since all of it is safely stored in the virtual machine’s memory. Virtual Machines make it easy to migrate data from one computer to another without having to go through the tedious process of transferring data onto an external hard drive first.
A container is a method of running one or more applications on top of an operating system (OS) while sharing the OS’s kernel. While virtual machines (VMs) are generally used to create a completely isolated environment, containers are designed to be more lightweight and share resources between different applications. Containers allow for greater portability across different environments, where any one program might be required to run in several different places.
