What is a cloud server?

A cloud server is a centralized resource hosted online, providing on-demand access to processing power, storage, and applications for multiple users. Unlike traditional servers, which are located on-site for one organization’s use, cloud servers can be accessed remotely from anywhere in the world.

How does a cloud server work?

Cloud servers use virtualization, where a hypervisor abstracts and pools physical server resources to create virtual servers. This is part of the IaaS model, allowing organizations to access on-demand resources without owning hardware. Cloud servers are ideal for scalable, temporary workloads, but can also be configured as dedicated servers (bare metal) for specific customer needs.

Why is it called a cloud server?

When a computing resource is said to be “in the cloud,” it means that it is delivered over a network like the Internet, as opposed to being located on-premises and accessed directly. A cloud server is one of the most prominent examples of a cloud computing resource, along with cloud storage, databases, networking and software.

What is the difference between a cloud server and a dedicated server?

“The cloud” has come to be synonymous with the Internet in general. But there are actually many clouds, both public and private, which are formed by any set of connected servers that deliver computing resources over a network.

A cloud server can be contrasted with a dedicated server. While a cloud server’s resources can be shared by many users, a dedicated server is designed for exclusive use by one company. It must be set up and managed by that organization, while a cloud server can be owned and managed by a third party.

Which is the best cloud server?

Companies large and small have multiple options when it comes to choosing the right cloud server option. The best cloud servers are optimized for specific needs and budgets. What works for a global enterprise might not be right for a mid-market company.

Cloud servers can be deployed in three primary types of clouds:

Public cloud: Cloud servers are most commonly deployed via the public cloud. In this scenario, a third-party provider owns and manages the servers and other infrastructure, and gives its customers access to on-demand computing services.
Private cloud: A company can host its own cloud servers privately and maintain control of their management and maintenance. These server resources are not shared with other organizations, but since they are in the cloud, they can be accessed remotely by any employee, typically through a company intranet or VPN.
Hybrid cloud: Public and private clouds can be combined with on-premises cloud servers and off-site cloud servers working together. This hybrid cloud environment gives companies more options and flexibility to maintain control and security when necessary. It also leverages public clouds when they must quickly expand to meet surges in demand.

What are the benefits of a cloud server?

Cloud servers have revolutionized the IT industry. Countless companies have moved away from dedicated servers, centralized servers, and infrastructure setups to take advantage of this game-changing technology.
Four primary benefits drive this shift:

Affordability: Using cloud servers managed by third-party providers is far less expensive for a company than purchasing and maintaining their own infrastructure. Companies benefit from economies of scale when sharing server resources with others, and they pay only for the resources they use.

Convenience: Public cloud resources can often be provisioned in a matter of minutes and easily managed through a single control panel or API. When IT teams no longer need to maintain complex infrastructures on-premises, their resources are freed up for other tasks. Users can access data from anywhere.

Scalability: As computing and data storage needs change, cloud servers can respond quickly, scaling up or down to meet demand.

Reliability: Cloud servers can deliver the same performance as dedicated servers. Since the cloud runs on multiple servers in a shared environment, service can continue even if a single component fails.

The pros and cons of a cloud server

The pros of using cloud servers—cost-effectiveness, scalability, and flexibility—far outweigh the cons. But for some organizations, cloud servers will not meet all their needs.
One of the challenges is having less control, since a company using a public cloud does not manage its own infrastructure in-house. If a public cloud experiences an outage or slows down due to unexpected demand from other customers, they must wait for the provider to fix the issue.
That is why some companies choose to deploy a mix of cloud and on-premises infrastructure. The latter can be dedicated to mission-critical or high-security workloads, keeping them under their own control.

How many cloud servers are there?

Companies have myriad choices for server equipment and hosting. They can choose from hundreds of cloud providers to deliver services. Cloud servers continue to grow as data centers and server farms expand worldwide. To meet the growing demands of computers and connected devices, several hundred million servers may be needed soon.
