    What is a Cloud Server?

    Cloud servers, also known as virtual servers or virtual private servers (VPS), allow access to computing resources like processing power, storage, and applications over the internet. Cloud servers are housed in remote data centers and are not hardware-dependent.

    Cloud servers divide a physical server into several virtual servers with specialized CPU, RAM, and storage. Users can access a fraction of the server's resources without expensive hardware or infrastructure. Businesses save money and have flexibility by scaling cloud servers up or down.

    Cloud servers let organizations store and analyze data on-demand and access apps from anywhere with an internet connection. They host websites, execute programs, and store data securely and scalable for enterprises of all sizes. 

    Why is it called a Cloud Server?

    Cloud servers get their name from the ubiquitous "cloud" icon for the web and other networks. The internet is often referred to as "the cloud" as a metaphor for its pervasiveness and breadth, just as clouds in the sky are often constant and spread out over wide areas. Computing resources such as processing power, storage space, and application software can be accessed via the internet from "cloud servers," a special form of a distant server. Like clouds, which can be seen from nearly anywhere on Earth, cloud servers are accessible from anywhere in the world because to the internet's role as a delivery mechanism. The term "cloud" can also allude to the fact that cloud servers' underlying physical infrastructure is hidden from the user, giving the impression that one can access computing resources from an immaterial, amorphous pool. 

    How Does a Cloud Server Work?

    • A cloud server is a computer system housed in the cloud and run by a third-party service provider. With virtual infrastructure, numerous physical servers are networked together and made to function as a single entity.  
    • Any time a user needs to connect to a server hosted in the cloud, the request goes through the provider's network. A cloud provider spins up a virtual computer by allocating computing, memory, and storage space.  
    • Depending on the OS and software being used, the user can then connect to the virtual machine or instance through the internet via a remote desktop protocol (RDP) or a secure shell (SSH) protocol.  
    • Servers in the cloud can be tailored to each user's needs by installing and configuring only the programmes, services, and settings they want. The user is only charged for their resources, as the cloud server can be scaled up or down as needed.  
    • The cloud service provider handles the hardware, software, and security updates behind the scenes. Users can stop worrying about managing the underlying infrastructure and instead concentrate on their data and apps.  
    • Cloud servers, in general, provide a convenient, scalable, and inexpensive way to tap into computer power whenever needed. 

    More technically,  
     A cloud server is, at its core, a VM hosted on top of a real server in a datacenter. A physical server is a powerful computer configured to accommodate numerous virtual servers. 

    A hypervisor, a type of software that controls virtual machine formation, deletion, and resource allocation, is often installed on the server to make this possible. The hypervisor acts as an intermediary between the underlying hardware and any virtual computers that may be installed on it.  

    When a server is formed in the cloud, the hypervisor copies the server's operating system and hardware components into a virtual computer. The hypervisor also provides the VM with a virtual network interface card (NIC) that facilitates its interactions with other VMs and the outside world.  

    The virtual machine then starts up and loads the operating system and any other programmes that have been loaded, just like a real computer. The virtual machine (VM) appears to the software installed on it as if it were a standalone computer with its own set of hardware and resources.  

    As far as the datacenter is concerned, however, the VM is merely one of many instances operating on the actual server. The hypervisor is responsible for allocating resources fairly among the virtual machines (VMs), and it can adapt to fluctuating demands in real time.  

    Cloud companies often employ a cluster of actual servers, each hosting many virtual machines, to guarantee high availability and fault tolerance. Without any downtime for end users, virtual machines can be immediately moved from one failing physical server to another in the cluster by the hypervisor.

    Storage arrays, network switches, and load balancers are all part of the datacenter's infrastructure that contributes to providing a dependable, high-performance setting for the virtual machines.

    In general, the cloud server concept eliminates the need for the management and upkeep of physical hardware while providing a flexible, scalable, and cost-effective means of providing computing resources to customers.

    Key Features of Cloud Servers

    Cloud servers have the following key characteristics:

    • Scalability: refers to the ability of cloud servers to easily scale up or down in response to changing demand. Users can avoid the costs associated with over-provisioning by paying for only the resources they require.
    • Flexibility: Cloud servers are highly configurable and can be tailored to specific needs. Users can create a server that meets their needs by selecting from a variety of operating systems, software applications, and configurations.
    • Cost-effectiveness: Cloud servers are typically less expensive than traditional physical servers because they do not require expensive hardware or maintenance. Users only pay for the resources they use, which helps to reduce overall IT costs.
    • Reliability: Cloud servers are built to be highly available and redundant, ensuring that applications remain accessible even if hardware fails. Many cloud service providers provide service level agreements (SLAs) that ensure uptime and availability.
    • Security: Because advanced security features such as firewalls, intrusion detection and prevention, and data encryption are available on cloud servers, they are typically more secure than traditional physical servers. To ensure the security of their infrastructure, cloud providers typically have dedicated security teams and resources.
    • Accessibility: Cloud servers are accessible via the internet from anywhere in the world, allowing users to work remotely and collaborate with team members in different locations.

    Overall, cloud servers are a highly flexible, cost-effective, and dependable way to access computing resources on demand.

    Cloud Server vs Traditional Server

    The infrastructure, scalability, cost structure, maintenance needs, availability, and reliability of cloud servers are not the same as those of conventional servers.

    Traditional servers are physical servers owned and maintained by an enterprise, while cloud servers are virtual servers hosted in a cloud computing environment. In contrast to traditional servers, which require manual upgrades and maintenance to scale, cloud servers can be quickly expanded or contracted in response to fluctuations in demand. Because they don't require any special hardware or ongoing maintenance, cloud servers are often more cost-effective than conventional ones. Unlike traditional servers, which must be maintained and updated by in-house IT staff, cloud servers are managed by the cloud provider. While using a cloud server, you don't need to be in the same physical place as the server to access its contents. While traditional servers may go down due to hardware failure or other difficulties, cloud servers are built to be highly available and provide redundancy.

    Cloud servers are a more flexible, scalable, and cost-effective alternative for many businesses, but traditional servers offer more control and protection.
