Cloud Hosting

Today, available compute options for cloud services go beyond just bare metalservers and cloud servers.Containersare becoming a default infrastructure choice for manycloud-nativeapplications. Platform-as-a-service (PaaS) offerings have an important niche of the applications market for developers who don't want to manage an OS or runtime environment. Andserverless computingis emerging as the model of choice for cloud purists.

But, when evaluating bare metal servers, users still gravitate toward the comparison to virtual servers. For most companies, the criteria for choice are application specific or workload specific. It's extremely common for a company to use a mix of bare metal servers along withvirtualizedresources across their cloud environment.

Virtual servers are the more common model of cloud computing because they offer greater resource density, faster provisioning times, and the ability to scale up and down quickly as needs dictate. But bare metalservers are the right fit for a few primary use cases that take advantage of the combination of attributes. These attributes are dedicated resources, greater processing power, and more consistent disk and network I/O performance.
