A cloud-based infrastructure has several key components, including, but not limited to a combination of:
- Network devices, and
- Storage resources
The traditional in-house file server is the central computing and storage hardware component that businesses have relied on for decades to run its everyday software applications. Cloud based file services are now available to replace the costly on site equipment with computing power in a service cloud where the file service resources of CPU and memory are now purchased as a service. The cloud file server cost is equivalent to the cost over time of an on site file server but without the need for expensive maintenance contracts, space and power needs. This allows computing power on demand without a high upfront cost. Business critical applications for every business are now available to run in the cloud. Even aged software programs can be virtualized to run in a file server environment in the cloud.
Network appliances such as firewalls, routers and switches are available to run under a virtual or cloud environment. This permits businesses to consolidate its file services and network appliances into a file server cluster for redundancy and economy of scale.
DNS can provide cloud services in its data centers or using one of its cloud partners.
