Simply put, cloud computing is 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. You typically pay only for the cloud services you use, which helps you lower operating costs, run your infrastructure more efficiently, and scale as your business needs change.(Video) What is the cloud? An introduction to cloud computing with Microsoft Azure.
The main advantages of cloud computing
Cloud computing is a big shift from the traditional way businesses think about IT resources. Here are seven common reasons why organizations turn to cloud computing services:
Moving to the cloud helps companies optimizeThat costs money. That's because cloud computing eliminates the capital cost of buying hardware and software and setting up and running on-site data centers—racks of servers, 24-hour electricity for power and cooling, and IT professionals to manage the infrastructure. It adds up quickly.
Most cloud computing services are self-service and on-demand, so even massive amounts of computing resources can be provisioned in minutes, usually with just a few mouse clicks, giving companies a lot of flexibility and reducing pressure on capacity planning.
The benefits of cloud computing services include the ability to scale elastically. When talking about the cloud, this means delivering the right amount of IT resources - for example, more or less computing power, storage, bandwidth - exactly when they are needed and on the right sidegeographical location.
On-premises data centers typically require a lot of "stacking and stacking"—hardware deployment, software patching, and other time-consuming IT management tasks. Cloud computing removes the need for many of these tasks, so IT teams can spend time on more important business goals.
The largest cloud computing services operate on a worldwide network of secure data centers, which are regularly upgraded with the latest generation of fast and efficient computing hardware. This offers several advantages over a single corporate data center, including reduced network latency for applications and greater economies of scale.
Cloud computing makes a backup copy of data,disaster recovery, and business continuity is easier and cheaper because data can be mirrored to multiple redundant locations on the cloud service provider's network.
Many cloud providers offer a broad set of policies, technologies, and controls that collectively strengthen your security posture, helping to protect your data, applications, and infrastructure from potential threats.
Types of cloud computing
Not all clouds are the same, and no one type of cloud computing is right for everyone. Several different models, types and services have been developed to offer the right solution for your needs.
You must first determine the type of cloud deployment or cloud computing architecture on which your cloud services will be deployed. There are three different ways to deploy cloud services: on a public cloud, a private cloud, or a hybrid cloud.Learn more about public, private and hybrid clouds.
Public cloudsare owned and operated by a third partycloud service providers, which deliver computing resources such as 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.
Aprivate cloudrefers to cloud computing resources used exclusively by one company or organization. A private cloud can be physically located in a company's on-site data center. Some companies also pay third-party service providers to host their private cloud. A private cloud is one where services and infrastructure are hosted on a private network.
Hybrid cloudsthey combine public and private clouds, connected by technology that allows 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 and more deployment options, and helps optimize your 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). These are sometimes referred to as "stacks" of cloud computing because they build on each other. Knowing what they are and how they differ will make it easier for you to achieve your business goals.
The most basic category of cloud computing services. WITHinfrastructure as a service (IaaS), you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from cloud providers on a pay-as-you-go basis.
Platform as a Service (PaaS)refers to cloud computing services that provide an on-demand 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 server, storage, network and database infrastructure required for development.
Software as a Service (SaaS)is a method for delivering software applications over the Internet, on demand and usually on a subscription basis. With SaaS, cloud service providers host and manage the software application and underlying infrastructure, and handle all maintenance, such as software upgrades and security patches. Users connect to the app over the Internet, usually through a web browser on their phone, tablet, or computer.
Overlap with PaaS,serverless computingit focuses on building application functionality without spending time constantly managing the servers and infrastructure required to do so. The cloud service provider handles deployment, capacity planning and server management for you. Serverless architectures are highly scalable and event-driven, using resources only when a specific function or trigger occurs.
Using cloud computing
You're probably using cloud computing right now, even if you're not aware of it. If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it's likely that cloud computing makes it all possible behind the scenes. Various organizations - from small startups to global corporations, government agencies to non-profit organizations - have embraced cloud computing technology for a variety of reasons.
Here are some examples of what is possible with cloud services from cloud providers:
Create cloud-native applications
Quickly build, deploy, and scale applications—web, mobile, and API. Leverage cloud-native technologies and approaches such as containers,Kubernetes, microservices architecture, API-driven communication, and DevOps.
Store, backup and recover data
Protect your data more cost-effectively—and at scale—by transferring your data over the Internet to an external cloud storage system that's accessible from any location and any device.
Stream audio i video
Connect with your audience anywhere, anytime, on any device with high-definition video and audio with global distribution.
Delivery of software on demand
Also known as software as a service (SaaS), software on demand allows you to offer customers the latest software versions and updates – whenever they need it, wherever they are.
Test and build applications
Reduce application development costs and time by using cloud infrastructures that can easily scale up or down.
Analyze the data
Consolidate your data across teams, departments and locations in the cloud. Then use cloud services, such as machine learning and artificial intelligence, to uncover insights to make more informed decisions.
Build in intelligence
Use intelligent models to engage customers and provide valuable insights from collected data.

The cloud is a large network of remote servers around the world. These servers store and manage data, run applications, and deliver content and services such as streaming video, webmail, and office productivity software over the Internet. Storing your files and data in the cloud frees you from relying on local computers and servers. Instead, you can access your data online from any internet-capable device, whenever and wherever you want.
Multicloud computing refers to the use of multiple cloud computing services from more than one cloud service provider for the same type of IT solution or workload. A multicloud strategy—which can include both private and public clouds—helps organizations reduce risk and offers increased workload flexibility. Choosing the different offerings and capabilities of more than one cloud service provider allows organizations to build solutions that best suit their specific IT needs.
In general, cloud computing does not require technical IT experience. Cloud computing simply refers to the delivery of computing services over the Internet, including storage, databases, software, and analytics. Whether you have a basic understanding of computing concepts and terminology or are a more technical worker, you can apply the local computing knowledge and skills you currently have to the cloud.
Cloud service providers typically use a pay-as-you-go pricing model, meaning organizations only pay for the cloud services they use.
