A virtual machines is a part of IaaS and allows the user to provision any machine running on the cloud; the user can remotely connect to that machine and do whatever they want. With virtual machines, you can also manage resources such as CPU, memory, and disks (HDD or SSD), and all are quite easy to set up using the cloud portal. Similar to virtual machines, Microsoft has also introduced the concept of containers. Containers are light-weight application hosts, which refers to virtualized resources such as filesystem, windows registry, and others. Containers run on top of virtual machines to sandbox any application running inside it. We can set up a Linux virtual machine and set up a container, which runs ASP.NET Core, on top of it. Containers are now only supported on the Linux platform but Microsoft is working on it being supported on Windows as well. Moreover, containers are cheaper than virtual machines in terms of cost.
