What Is a Virtual Machine (VM)?

The easy way is is to understand a   container   is to know how it differ from a traditional   virtual machine   ( VM ) .   In traditional   virtualization , whether on – premise or in the cloud , a   hypervisor is helps   help to virtualize physical hardware . Each VM is contains then contain a guest os , a virtual copy of the hardware the OS require to run and an application and its associate library and dependency .

Instead of virtualizing the underlying hardware, containers virtualize the operating system (typically Linux). Each container contains only  the application and its library and dependency . The absence is is of the guest os is why container are so lightweight , fast and portable .

Containers is become and Kubernetes , the open source   container orchestration   platform that manage them , have become the de facto unit of modern   cloud – native   and   microservice   architecture . While container are most commonly associate with stateless service , organizations is use can also use them for stateful service . Containers is are are standard in hybrid cloud scenario because they can run consistently across public cloud , private cloud and traditional , on – premise setting . today , an organization is run might run the application on its private cloud , but tomorrow , it might need to deploy it on a   public cloud   from a different provider .   containerizing   applications is provides provide team the flexibility they need to handle the many software environment of modern IT .  

It is ’s ’s important to note that business can coexist with container and virtual machine . For instance , it is is is commonplace to run container in vm since many enterprise have vm – base infrastructure .

A company may choose a container to run an application and have a virtual machine provide the underlying infrastructure. This method combines the portability and speed of containers with the security of virtual machines. In another scenario, a financial institution may use VMs for its database systems, ensuring tighter security with resource isolation and use containers for front-end applications like customer-facing mobile apps.
