This can be especially useful for businesses that need to scale quickly to meet changing demands. With cloud computing, users can rapidly scale up or down to match their needs, thanks to the ability to elastically provision and release resources. Cloud systems automatically control and optimize resource use, providing transparency for both the provider and consumer.

Some of the key features of cloud computing include:

These features enable users to access cloud data or upload data to the cloud from anywhere with an internet connection, using any device. This flexibility is made possible by the use of resource pooling, which allows multiple users to share the same physical resources while retaining privacy and security over their own data.

Cloud computing offers a significant advantage in terms of hardware and software elimination. With cloud computing, you no longer need to have your own server, cables, network switches, backup generators, redundant routers, and so on.

This can greatly reduce expenses, which is essential in any business model. Every cloud-based platform benefits from this factor alone.

By using cloud computing, you can avoid managing the underlying infrastructure, such as the network, servers, operating systems, or storage. This is particularly appealing to developers, startups, and users building their own apps, as it provides the basics needed to develop other software or media.

Purchasing resources from a vendor on a pay-as-you-go basis allows you to access them over a secure connection, without having to worry about software maintenance, planning, or resource procurement.

Cloud computing has several key characteristics that make it a powerful tool for businesses and individuals. One of the most significant advantages of cloud computing is its ability to provide on-demand self-service, allowing users to provision computing capabilities automatically without requiring human interaction with each service provider.

Self-service provisioning is a hallmark of cloud computing, enabling end users to spin up compute resources for almost any type of workload on demand. This eliminates the need for IT administrators to provision and manage compute resources, making it a more efficient and cost-effective option.

Cloud computing also offers elasticity, allowing companies to freely scale up as computing needs increase and scale down as demands decrease. This eliminates the need for massive investments in local infrastructure, which might not remain active.

Cloud services provide a measured service, automatically controlling and optimizing resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service. Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

In addition to these characteristics, cloud computing also offers broad network access, allowing users to access cloud data or upload data to the cloud from anywhere with an internet connection using any device. This is made possible by the use of standard mechanisms that promote use by heterogeneous thin or thick client platforms.

Cloud computing environments are infinitely scalable, allowing companies to increase or decrease their bandwidth to cope with varying demands. This means cloud infrastructure grows seamlessly with your operation – never holding you back.

Here are the essential characteristics of cloud computing, as identified by the National Institute of Standards and Technology (NIST):

These characteristics are the foundation of cloud computing, enabling businesses and individuals to take advantage of the many benefits that cloud computing has to offer.

Cloud computing is perfect for virtualized computer environments because cloud resources can be allocated instantly to support significant increases in demand so you never experience downtime again. With cloud computing, your business can expand its capabilities almost effortlessly to meet growing demands without increasing staff or capital expenditures.

Virtualization is a key technology in cloud computing, allowing IT organizations to create virtual instances of servers, storage, and other resources that can be run on a single physical server using software known as a hypervisor. This simplifies the abstraction and provisioning of cloud resources into logical entities, letting users easily request and use these resources.

A hypervisor runs the virtual machines as guests, and pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements. Linux containers run in isolated partitions of a single Linux kernel running directly on the physical hardware.

Virtualized computing environments can be managed and provisioned using automation and orchestration capabilities, which provide users with a high degree of self-service to provision resources, connect services, and deploy workloads without direct intervention from the cloud provider's IT staff.

Here are some benefits of virtualized computing environments:

Virtual desktop infrastructure (VDI) is another important use case for virtualized computing environments, allowing organizations to stream the desktop image remotely without coupling the desktop with the physical client device. This can be especially useful for remote worker productivity, as applications and services can be easily deployed to a remote client without any complex installation or configuration.

Cloud computing offers various types of services to cater to different needs. There are three major cloud computing services that make up the majority: infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS).

IaaS provides virtualized computing resources over the internet, allowing businesses to scale up or down as needed. This service model is ideal for companies that require a lot of customization and control over their infrastructure.

PaaS offers a platform for developing, running, and managing applications without the need for underlying infrastructure. With PaaS, businesses can focus on writing code rather than managing servers and infrastructure.

SaaS hosts software on cloud servers, giving customers access over the internet. This service model is suitable for companies looking for easy access, fast deployment, and ready-built software.

Cloud computing can also be classified into public, private, and hybrid deployment models. Private clouds are offered over a private IT network for the dedicated use of a single organization.

Hybrid clouds combine public cloud services and on-premises private clouds, allowing companies to run mission-critical workloads on the private cloud and use the public cloud to handle workload bursts or spikes in demand.

In a hybrid cloud model, companies can scale their on-premises infrastructure up to the public cloud to handle overflow, ensuring that no third-party data centers have access to their data.

Infrastructure as a Service (IaaS) is a type of cloud computing that provides users with virtualized computing resources over the internet. This model allows users to have control over the storage, operating systems, and deployed applications, but not the underlying cloud infrastructure.

IaaS providers, such as Amazon Web Services (AWS), supply virtual server instances and storage, as well as application programming interfaces (APIs) that let users migrate workloads to a virtual machine (VM). Users have an allocated storage capacity and can start, stop, access and configure the VM and storage as desired.

IaaS clouds often offer additional resources such as virtual-machine disk-image libraries, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. The NIST's definition of cloud computing describes IaaS as "where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications."

The use of containers offers higher performance than virtualization because there is no hypervisor overhead. IaaS providers supply resources on-demand from their large pools of equipment installed in data centers, and customers can use either the Internet or carrier clouds (dedicated virtual private networks) for wide-area connectivity.

Here are some key benefits of IaaS:
