Cloud Server

What is a Cloud Server?

 

A cloud server is a centralized, pooled server resource that is hosted and deployed on a network (typically the Internet) and accessed on demand by multiple users. Cloud servers can perform the same functions as a traditional physical server and offer processing power, storage and applications. 

Cloud servers can be located anywhere in the world and provide services remotely through a cloud computing environment. In contrast, traditional dedicated server hardware is typically configured on-premises and used exclusively by a business.

How does a cloud server work?

Cloud servers are the result of virtualization. Management software, called a hypervisor, is installed on physical servers in order to connect and virtualize them; the hypervisor abstracts their combined resources and aggregates them to create virtual servers. These virtual resources are then automated and deployed in the cloud, and their use is shared within an enterprise or across multiple enterprises.

This approach is known as the infrastructure-as-a-service (IaaS) model. Businesses using IaaS don't have to manage and own their own hardware; they can provision it from third parties that provide on-demand resources through a public cloud. Here's a common example of a cloud server: using a public cloud for temporary, occasional, or variable workloads that need to scale vertically and quickly when needed.

However, in some cases it is also possible to configure cloud servers as dedicated servers by a cloud provider. In this configuration, sometimes referred to as a bare metal server, the provider dedicates physical cloud servers to a customer who has specific performance and storage requirements.

Why is it called a cloud server?

When a computing resource is said to be “on the Cloud”, it means that it is deployed on a network such as the Internet, unlike resources located on premise and accessible directly. The cloud server is one of the best-known examples of cloud computing resources, alongside cloud storage, databases, networks and software.
 

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

“The Cloud” has gradually become synonymous with the Internet in general. In reality, there are many clouds, whether public or private. They are made up of a set of connected servers that deploy computing resources over a network.

 

A cloud server differs from a classic dedicated server. While the resources of a cloud server can be shared by multiple users, a dedicated server is designed to be used exclusively by a company. It must be configured and managed by said company, while a cloud server can be owned and managed by a third party.
 

What is the best cloud server?

Businesses large and small have just as many choices when it comes to selecting the right cloud server solution. The best cloud servers are optimized to meet specific needs and budgets. What is suitable for a global company may not be suitable for a medium-sized company.

 

Cloud servers are deployable through three main types of cloud:

 

Public cloud  : Cloud servers are most often deployed through the public cloud. In this scenario, a third-party provider owns and manages the servers and other infrastructure, then provides its customers with access to on-demand computing services.

 

private cloud  : A company can host its own Cloud servers privately and retain control over their management and maintenance. These server resources are not shared with other companies, but since they are in the cloud, they can be accessed remotely by any employee, typically via the company intranet or VPN.

 

Hybrid cloud  : Public and private clouds can be combined with on-premise cloud servers and off-site cloud servers working together. Thanks to this hybrid cloud environment, companies benefit from greater flexibility to maintain control and guarantee the security of their data if necessary. They also leverage public clouds when they need to scale quickly to meet an increase in demand.
 

What are the benefits of a cloud server?

Cloud servers have revolutionized the IT industry. Countless companies have abandoned traditional, centralized infrastructure and server configurations to take advantage of this revolutionary technology. Four key benefits are driving this change:

• Accessibility: Using cloud servers managed by third-party providers is much less expensive for a company than buying and managing its own infrastructure. Sharing server resources with other organizations allows companies to realize great savings. Plus, they only pay for the resources they use.
  
  
• Convenience: Public cloud resources are often provisionable in minutes, and easily managed through a single control panel or API. When IT teams no longer need to maintain complex on-premises infrastructures, resources are freed up for other tasks. Users have access to data wherever they are.
  
  
• Scalability: Cloud servers scale up or down to meet demand if changes are needed in computing and data storage.
  
  
• Reliability: Cloud servers demonstrate the same performance as dedicated servers. Because the cloud runs on multiple servers in a shared environment, service delivery can continue even if one component fails.

Advantages and disadvantages of a cloud server

When it comes to using cloud servers, the advantages (cost effectiveness, scalability and flexibility) far outweigh the disadvantages. However, cloud servers may not meet all of a company's needs.

 

The lack of control can be a challenge, since a company using a public cloud does not manage its own infrastructure internally. If a public cloud experiences an outage or slowdown due to unexpected demand from other customers, users should wait for the provider to resolve the issue.

 

It is for this reason that some companies prefer to deploy both a cloud infrastructure and an on-premises infrastructure. Companies can dedicate the latter to mission-critical or high-security workloads to keep them under control.
 

How many cloud servers are there?

When it comes to server hosting equipment and solutions, companies have the choice of the king. Hundreds of cloud providers offer to deploy services. The number of cloud servers continues to grow as data centers and server farms grow around the world. Several hundred million servers could be needed very soon to satisfy the growing demand for computers and connected terminals.
