Cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytic, and more—over the cloud. Companies offering these hybrid computing services are called cloud providers and typically charge for cloud computing security services based on usage, similar to how you’re billed for water or electricity at home.
Cloud computing is a big shift from the traditional way businesses think about IT resources. What is it about cloud computing? Why is cloud computing so popular? Because it has 6 advantages including cost, speed, global scale, productivity, performance, reliability. It runs on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate data center, including reduced network latency for applications and greater economies of scale. Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive, because data can be mirrored at multiple redundant sites on the cloud provider’s network.
The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them. Most cloud computing services fall into three broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (Saas). These are sometimes called the cloud computing stack, because they build on top of one another. Knowing what they are and how they’re different makes it easier to accomplish your business goals, and it services all work a little differently, depending on the provider. But many provide a friendly, browser-based dashboard that makes it easier for IT professionals and developers to order resources and manage their accounts. Some cloud computing services are also designed to work with REST APIs and a command line interface (CLI), giving developers multiple options.
Types of cloud service are different, there are three ways to deploy cloud computing security service, such as, public cloud, private cloud and hybrid cloud. Public clouds are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet. Microsoft Azure is an example of a public cloud. With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. You access these services and manage your account using a web browser. Private clouds refer to cloud computing resources used exclusively by a single business or organization, which can be physically located on the company’s on-site data center, and some companies also pay third-party service providers to host their private cloud. It is one in which the services and infrastructure are maintained on a private network. Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them,and hybrid cloud gives businesses greater flexibility and more deployment options by allowing data and applications to move between private and public clouds.
