What Is Cloud Computing
Cloud computing is the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This technology allows organizations to scale their IT infrastructure on demand, pay only for the resources they use, and improve IT agility. The National Institute of Standards and Technology (NIST) defines cloud computing as:
“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This technology allows organizations to scale their IT infrastructure on demand, pay only for the resources they use ,and improve IT agility.” In simple terms, cloud computing means using someone else’s computer instead of your own. The “cloud” refers to the internet which connects you to these remote computers that store your data and run your applications .
When you are using cloud services , all you need is an internet connection – there is no need to install or download anything onto your own computer . There are three main types of cloud service : Infrastructure as a Service (IaaS) – this provides you with access to remote computers that can be used to store data or run applications.
An example of IaaS would be Amazon Web Services (AWS). Platform as a Service (PaaS) – this provides you with access to a platform that can be used to develop or run applications. An example of PaaS would be Google App Engine .
Software as a Service (SaaS) – this provides you with access to software that can be used over the internet . An example of SaaS would be Microsoft Office 365 .
What is Cloud Computing in Simple Terms?
Cloud computing is a type of internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This can be seen as an extension of the client–server model where the client still pays for the resources but does not need to own or maintain them themselves.
What is Cloud Computing Example?
Cloud computing can be defined as the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. For example, a company that needs to store large amounts of data may use Amazon Simple Storage Service (S3), which is an object storage service that offers industry-leading scalability, data availability, security, and performance. S3 enables companies to pay only for the storage they actually use.
There is no minimum fee and no setup cost. Users can access their data from anywhere in the world using the Amazon S3 API or via the AWS Management Console.
