Containers are lightweight alternative by taking up less space (MBs) and can be provisioning rapidly (milliseconds) as opposed to VM’s slow boot time (minutes) and more storage space requirements (GBs). On the other hand, containers share the same operating system kernel with collocated containers each one running as isolated processes. virtual machine manager).Įven though virtual machines bring us great deal of advantages such as running different operating systems or versions, VMs can consume a lot of system resources and also take longer boot time. In cloud computing, physical hardware on a bare metal server are virtualized and shared between virtual machines running on a host machine in a data center by the help of hypervisor (i.e.
#Use of docker and kubernetes full
Virtual machines allow you to run a full copy of an operating system on top of virtualized hardware as if it is a separate machine. The Benefits and Limitations of Virtual Machines Since VMs existed long before containers, you may wonder what the need is for containers and why they have become so popular.
At the same time, however, virtual machines (VM) as computing resources have reached their peak use in virtualized data centers. It’s unsurprising then, that container technologies, which make application deployment and management easier for teams of all sizes, have risen dramatically in recent years. The need to deploy applications from one computing environment to another quickly, easily, and reliably has become a critical part of enterprise’s business requirements and DevOps team’s daily workflow.
