what in the cloud computing
Keituber.com – Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to deliver rapid innovation, flexible resources, and economies of scale. You pay only for the cloud services you typically use, reducing your operating costs, running your infrastructure more efficiently, and at the scale your business needs.
The biggest benefits of cloud computing
Cloud computing is a big shift from the traditional way businesses think about IT resources. Here are seven common reasons organizations turn to cloud computing services:
Cost
Cloud computing eliminates the capital costs of purchasing hardware and software and setting up and running on-site datacenters—racks of servers, around-the-clock electricity for power and cooling, and IT professionals to manage the infrastructure. It adds up quickly.
Speed
Most cloud computing services are self-service and on-demand, so even massive amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses more flexibility and relieving the burden of capacity planning.
International scale
Advantages of cloud computing services include flexibility. In cloud terms, that means delivering the right amount of IT resources — for example, more or less computing power, storage, bandwidth — when you need it and from the right geographic location.
Productivity
On-site datacenters require a lot of “stacking and stacking”—hardware setup, software maintenance, and other time-consuming IT management tasks. Cloud computing eliminates the need for many of these tasks, so IT teams can spend time achieving more important business goals.
Performance
The largest cloud computing services operate a global network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This provides several advantages over a single corporate data center, including reduced network latency and greater economy for applications.
Reliability
Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored across multiple redundant sites on the cloud provider’s network.
Security
Many cloud providers offer a wide range of policies, technologies and controls to help protect your data, applications and infrastructure from potential threats.
Types of cloud computing
Not all clouds are the same and one type of cloud computing is not for everyone. Various models, types and services have been developed to help provide the right solution for your needs.
First, you need to determine the cloud deployment or cloud computing architecture on which your cloud services will be implemented. There are three different ways to deploy cloud services: public cloud, private cloud or hybrid cloud. Learn more about public, private and hybrid clouds.
Public cloud
Public clouds are owned and implemented by third-party cloud service providers, who deliver their computing resources, such as servers and storage, over the Internet. Microsoft Azure is an example of a public cloud. In a public cloud, all hardware, software, and other supporting infrastructure are owned and controlled by the cloud provider. You access these services and manage your account using a web browser. Learn more about public cloud.
Private cloud
A private cloud refers to cloud computing resources that are used exclusively by a business or organization. A private cloud can be physically located at a company’s on-site data center. Some companies pay third-party service providers to host their private cloud. A private cloud is where the services and infrastructure reside on a private network. Learn more about private cloud.
Mixed cloud
Hybrid clouds combine public and private clouds, enabling technology-linked data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business more flexibility, more deployment options, and helps optimize existing infrastructure, security and compliance.

Types of cloud services: IaaS, PaaS, Serverless and SaaS
Most cloud computing services fall into four broad categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Serverless, and Software as a Service (SaaS). Because these build on top of each other, they are sometimes called cloud computing “stacks.” Knowing what they are and how they differ will make achieving your business goals easier.
Infrastructure as a Service (IaaS)
The most basic category of cloud computing services. With IaaS, you rent IT infrastructure—servers and virtual machines (VMS), storage, networks, operating systems—from the cloud provider on a pay-as-you-go basis.

Platform as a Service (PaaS)
Platform as a Service refers to cloud computing services that provide an environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it easy for developers to quickly create web or mobile applications without having to worry about setting up or managing the underlying infrastructure of servers, storage, networking and databases required for development.

Overlapping with PaaS, serverless computing focuses on building application functionality without spending time. The cloud provider handles the configuration, capacity planning and server management for you. Serverless architectures are highly scalable and event-driven, consuming resources only when a specific task or trigger occurs.

Software as a Service (SaaS)
Software as a service is a method of delivering software applications over the Internet, on demand and typically by subscription. With SaaS, cloud providers host and manage the software applications and underlying infrastructure, and handle any maintenance, such as software updates and security patches. Users connect to the Internet, often through a web browser on their phone, tablet, or PC.

Even if you don’t know it, you may be using cloud computing right now. Whether you use an online service to send email, edit documents, watch movies or TV, listen to music, play games, or store images and other files, cloud computing is probably doing everything behind the scenes. The first cloud…
