What is cloud computing?Cloud computing allows clients to access cloud services and data from remote servers, databases, and computers.

An internet connection connects the front, which is the accessing client device and browser with the backend, which consists databases, servers, and computers. The back end acts as a repository

and stores data that can be accessed by front end.A central server manages communications between the front end and back end. To facilitate data exchange, the central server uses protocols.

To manage connectivity between clients and cloud servers, the central server employs both middleware and software. Each application or workload typically has its own server.

Cloud computing is heavily dependent on virtualization, and automation technologies. Virtualization allows users to request and use services and underlying cloud systems by abstracting them into logical entities. With the orchestration capabilities, automation and associated automation capabilities, users can provide self-service to provision resources and connect services.

Who uses cloud computing?
Cloud computing is being used by organizations of all sizes and industries for many purposes, including data backup, disaster recovery and email. Healthcare companies use the cloud to create more customized treatments for their patients. The cloud is being used by financial services companies to enable fraud prevention and detection in real time. Video game developers are also using the cloud to distribute online games to millions around the globe.

Cloud computing services in different types
There are three types of cloud computing, or general service delivery categories for cloud computing.

IaaS. IaaS providers such as Amazon Web Services (AWS) provide a virtual server instance, storage, and application programming interfaces (APIs), which allow users to migrate workloads to virtual machines (VMs). The storage capacity is allocated to users. Users can access, modify, and stop the VM as well as access it. IaaS providers can offer small, medium, large and extra-large instances. They also have the ability to customize instances for different workloads. IaaS’s cloud model is closer to remote data centers for business users.
PaaS . Cloud providers host development tools on the infrastructures of their PaaS models. These tools can be accessed via APIs, web portals, or gateway software over the internet. PaaS can be used to develop general software. Many PaaS providers host the software once it has been developed. The most common PaaS products are Salesforce’s Lightning Platform and AWS Elastic Beanstalk.

Is a distribution model that delivers software over the internet. These applications are sometimes called web service . SaaS services and applications can be accessed from anywhere with an internet connection. SaaS allows users to access application software and databases. Microsoft 365 is a common SaaS application that provides productivity and email services.
