Should enterprises run containers in VMs or bare metal?

The article discusses the critical decision enterprises face regarding whether to run containerized applications on virtual machines (VMs) or directly on bare metal. It emphasizes that both approaches have their own advantages and disadvantages, shaping the performance, scalability, and management of applications in a cloud-native environment.

One key advantage of utilizing VMs is the inherent isolation and security they provide. This allows teams to effectively manage resources without the risks associated with running multiple containers directly on a single host. However, this added layer can introduce overhead, leading to potential performance bottlenecks.

On the other hand, running containers on bare metal can significantly enhance performance. With direct access to hardware, applications can benefit from lower latency and increased throughput. The article suggests that for high-demand applications where performance is a critical factor, bare metal might be the preferable option, despite possible drawbacks in resource management and flexibility.

Ultimately, the choice between VMs and bare metal should be driven by the specific needs of the organization, the workload characteristics, and the skill set of the DevOps team. The article also highlights that hybrid solutions may serve as an effective compromise, leveraging the strengths of both approaches while minimizing their weaknesses.
