The rising demand for fuel fuels this explosive growth.

What’s more?

• Remote work: As more people work from anywhere, cloud servers provide a secure and accessible platform for storing data and running applications.
• E-commerce boom: Online businesses rely heavily on cloud servers to handle high traffic volumes and ensure smooth customer experiences.
• Big data analytics: Businesses are turning to cloud servers to process and analyze massive datasets, gaining valuable insights for better decision-making.

How does a cloud server work?

Cloud servers provide access to computing resources, like storage and processing power, over the Internet. They offer scalability and flexibility at a potentially lower cost compared to physical servers that need maintenance.

How it works:

• Request for resources: You can specify your processing power, storage capacity, and memory requirements when contacting your chosen cloud service provider.
• Cloud provider infrastructure: The cloud provider operates large data centers housing multiple physical servers. A software layer, called a hypervisor, virtualizes these servers, dividing them into multiple isolated virtual machines (VMs).
• Provisioning your VM: Upon receiving your request, the provider will allocate resources from the available pool to create a new virtual machine on a physical server with the processing power, storage, and memory specifications you provided.
• Operating system and applications: You can install your preferred operating system, such as Windows or Linux, along with the necessary applications for your online store, such as database and shopping cart software.
• Secure remote access: The cloud provider provides secure remote access to your VM through the internet. This access typically requires a combination of a username, password, and multi-factor authentication for added security.
• User interaction: Customers can access your online store via a web browser. Requests are routed to the internet and then directed to your cloud server.
• Processing and response: Your virtual machine handles customer requests, retrieves data from storage, and generates web pages, which are then sent back to the customer’s browser, displaying your online store.
• Scaling on demand: If your website experiences a sudden increase in traffic, you can easily request additional resources from your cloud provider. This allows them to allocate more processing power or memory to your virtual machine on the fly, ensuring your online store remains responsive.
• Billing and management: You are billed based on actual usage (hourly or monthly) of allocated resources. The cloud provider manages infrastructure, including hardware, software, and security.

This simplified workflow shows the major aspects of how a cloud server works. We hope this workflow will help you to understand the entire process.

Cloud servers offer a compelling solution for businesses and individuals seeking a scalable, flexible, and potentially cost-effective computing environment. However, it’s important to weigh the advantages and disadvantages against your specific needs and priorities.

Types of cloud servers

Cloud servers offer a dynamic and scalable way to access computing resources. However, a “cloud server” contains various options catering to different needs. There are two major parts of a cloud server: the deployment model and the service model.

Let’s have a look:

a. Deployment model type

It means the location and accessibility of the cloud server’s infrastructure.

• Public cloud: These are the most common types. Major cloud service providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) own and operate public cloud servers. They offer on-demand, scalable resources accessible over the Internet to anyone with a credit card. Public cloud servers are a good option for businesses that need flexibility and cost-efficiency.
• Private Cloud: These are dedicated cloud servers designed for a single organization. A private cloud can be located on-premises or hosted by a service provider with dedicated infrastructure for that specific client. Private clouds offer greater security and control but come with higher costs and less scalability compared to public options.
• Hybrid Cloud: This combines elements of both public and private clouds. An organization might use a public cloud for non-critical workloads and a private cloud for sensitive data or applications requiring stricter control. Hybrid clouds offer a balance between security, flexibility, and cost.

b. Service model type

This type of cloud server means the kind of service it offers.

• Infrastructure-as-a-Service (IaaS): This provides the most basic level of service. With IaaS, you essentially rent virtualized computing resources like servers, storage, and networking. You have complete control over the operating system, applications, and data deployed on your virtual machines.
• Platform-as-a-Service (PaaS): PaaS goes a step further by providing a platform for developing, deploying, and managing applications. It includes the underlying infrastructure (servers, storage, and networking) as well as development tools and services. This allows developers to focus on building applications without worrying about managing the server infrastructure.
• Software-as-a-Service (SaaS): This offers on-demand access to software applications over the internet. The cloud provider manages everything—infrastructure, platform, and application—and users access the software through a web browser or API. SaaS is a popular choice for business applications like email, CRM, and project management software.

c. Others

• Community Cloud Servers: Community cloud servers are shared among several organizations with common concerns, such as regulatory compliance or industry-specific requirements.
• Dedicated Cloud Servers: Dedicated cloud servers are physical servers exclusively leased to a single client by a cloud provider.
• Managed Cloud Servers: Managed cloud servers are maintained and operated by a third-party provider, offering services such as monitoring, security, maintenance, and support.
• Serverless Computing: While not strictly servers in the traditional sense, serverless computing platforms (e.g., AWS Lambda, Azure Functions) allow developers to run code without provisioning or managing servers explicitly.

Each type of cloud server has its advantages and is suited to different use cases, depending on factors such as scalability requirements, security concerns, budget constraints, and regulatory compliance.
