There is controversy around whether bare metal will vanquish virtualized servers over the long term and running containers on bare metal is still far from mainstream.
Bare metal server vs vm vs container.
The simplest and most efficient way to run containers is to run them on bare metal machines rather than virtualized machines.
Containers can of course be run on virtualized servers and often are.
There are plenty of advantages to running containers on bare metal servers.
A container is an application execution environment that runs on top of a container engine which sits on an os.
When deciding on bare metal vs.
If the apps you want to run require bare metal access then it s best to run those apps on a bare metal server.
Or you could run your apps inside containers on bare metal to get the best of both worlds.
Containers are an os level isolation technology while vms isolate applications each with a separate os.
Vm deployment keep in mind that container architecture differs from vms.
Containers running on bare metal utilize system resources more efficiently than vm based containers.
As you can see from the results sample below the copying operations rate was at around 125mb s on the vm in comparison to around 165mb s.
By their very nature containers have all the resources they need to run including their own filesystems and network stacks which allows many.
The performance advantage of bare metal apps with the portability traditionally available only from virtual machines.
As shown below the performance of containers running on bare metal was 25 30 better compared to running the same workloads on vms in both cpu and io operations.
In this respect bare metal containers give you the best of both worlds.
