Simply put, cloud computing is that the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the web (“the cloud”) to supply faster innovation, flexible resources, and economies of scale. you sometimes pay just for cloud services you employ , helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.
Top benefits of cloud computing
Cloud computing may be a big shift from the normal way businesses believe IT resources. Here are seven common reasons organisations are turning to cloud computing services:
Cloud computing eliminates the capital expense of shopping for hardware and software and fixing and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. It adds up fast.
Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources are often provisioned in minutes, typically with just a couple of mouse clicks, giving businesses tons of flexibility and taking the pressure off capacity planning.
The benefits of cloud computing services include the power to scale elastically. In cloud speak, meaning delivering the proper amount of IT resources—for example, more or less computing power, storage, bandwidth—right when it’s needed and from the proper geographic location.
On-site datacenters typically require tons of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. Cloud computing removes the necessity for several of those tasks, so IT teams can spend time on achieving more important business goals.
The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the newest generation of fast and efficient computing hardware. This offers several benefits over one corporate datacenter, including reduced network latency for applications and greater economies of scale.
Cloud computing makes data backup, disaster recovery and business continuity easier and fewer expensive because data are often mirrored at multiple redundant sites on the cloud provider’s network.
Many cloud providers offer a broad set of policies, technologies and controls that strengthen your security posture overall, helping protect your data, apps and infrastructure from potential threats.
Types of cloud computing
Not all clouds are an equivalent and not one sort of cloud computing is true for everybody . Several different models, types and services have evolved to assist offer the proper solution for your needs.
First, you would like to work out the sort of cloud deployment or cloud computing architecture, that your cloud services are going to be implemented on. There are three alternative ways to deploy cloud services: on a public cloud, private cloud or hybrid cloud. Learn more about public, private and hybrid clouds.
Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the web . 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 employing a browser . Learn more about the general public cloud.
A private cloud refers to cloud computing resources used exclusively by one business or organisation. a personal cloud are often physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud. a personal cloud is one during which the services and infrastructure are maintained on a personal network. Learn more about the private cloud.
Hybrid clouds combine public and personal clouds, bound together by technology that permits data and applications to be shared between them. By allowing data and applications to maneuver between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options and helps optimise your existing infrastructure, security and compliance.

Types of cloud services: IaaS, PaaS, serverless and SaaS
Most cloud computing services fall under four broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless and software as a service (SaaS). These are sometimes called the cloud computing stack because they repose on top of 1 another. Knowing what they’re and the way they’re different makes it easier to accomplish your business goals.
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 a 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 on-demand environment for developing, testing, delivering and managing software applications. PaaS is meant to form it easier for developers to quickly create web or mobile apps, without fear about fixing or managing the underlying infrastructure of servers, storage, network and databases needed for development.
Overlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to try to to so. The cloud provider handles the setup, capacity planning and server management for you. Serverless architectures are highly scalable and event-driven, only using resources when a selected function or trigger occurs.
Software as a service (SaaS)
Software as a service may be a method for delivering software applications over the web , on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users hook up with the appliance over the web , usually with an internet browser on their phone, tablet or PC.
Microsoft may be a leading global provider of cloud computing services for businesses of all sizes. to find out more about the Microsoft cloud platform, our Kubernetes on Azure offering, our serverless application platform and the way Microsoft Azure compares to other cloud providers, see what’s Azure? and Azure vs. AWS.
