Lets Star basics idea of cloud computing

What is cloud computing?

Cloud computing is that the on-demand delivery of IT resources over the web with pay-as-you-go pricing. rather than buying, owning, and maintaining physical data centers and servers, you’ll access technology services, like computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services, Google GCP, Microsoft Azure, Salesforce, Etc.

 

 

Who is using cloud computing?

Organizations of each type, size, and industry are using the cloud for a good sort of use cases, like data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications. for instance , healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to power real-time fraud detection and prevention. And computer game makers are using the cloud to deliver online games to many players round the world.

Top benefits of cloud computing

Cloud computing may be a big shift from the normal way businesses believe in IT resources. Here are seven common reasons organizations are turning to cloud computing services:

Cost

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, and therefore the IT experts for managing the infrastructure. It adds up fast.

Speed

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.

Global scale

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 they’re needed, and from the proper geographic location.

Productivity

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.

Performance

The biggest cloud computing services run on a worldwide network of secure data centers, 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.


Reliability

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.

Security

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 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.

The three main sorts of cloud computing include Infrastructure as a Service, Platform as a Service, and Software as a Service. Each sort of cloud computing provides different levels of control, flexibility, and management in order that you’ll select the proper set of services 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.

Infrastructure as a Service (IaaS)

IaaS contains the essential building blocks for cloud IT. It typically provides access to networking features, computers (virtual or on dedicated hardware), and data space for storing. IaaS gives you the very best level of flexibility and internal control over your IT resources. it’s almost like the prevailing IT resources with which many IT departments and developers are familiar.

Platform as a Service (PaaS)

PaaS removes the necessity for you to manage underlying infrastructure (usually hardware and operating systems), and allows you to specialize in the deployment and management of your applications. This helps you be more efficient as you don’t get to worry about resource procurement, capacity planning, software maintenance, patching, or any of the opposite undifferentiated work involved in running your application.

Software as a Service (SaaS)

SaaS provides you with an entire product that’s run and managed by the service provider. In most cases, people pertaining to SaaS are pertaining to end-user applications (such as web-based email). With a SaaS offering, you don’t need to believe how the service is maintained or how the underlying infrastructure is managed. you simply got to believe how you’ll use that specific software.

Uses of cloud computing

You’re probably using cloud computing immediatelyalbeit you don’t know it. If you employ a web service to send an email, edit documents, watch movies or TV, hear music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes. the primary cloud computing services are barely a decade old, but already a spread of organizations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all kinds of reasons.

Here are a couple of samples of what’s possible today with cloud services from a cloud provider:

1. Create cloud-native applications

Quickly build, deploy, and scale applications—web, mobile, and API. cash in of cloud-native technologies and approaches, like containers, Kubernetes, microservices architecture, API-driven communication, and DevOps.

Test and build applications
Reduce application development cost and time by using cloud infrastructures which will easily be scaled up or down.

2. Store, back up, and recover data

Protect your data more cost-efficiently—and at a massive scale—by transferring your data over the web to an offsite cloud storage system that’s accessible from any location and any device.

3. Analyze data


Unify your data across teams, divisions, and locations within the cloud. Then use cloud services, like machine learning and AI, to uncover insights for more informed decisions.

4. Stream audio and video

Connect together with your audience anywhere, anytime, on any device with high-definition video and audio with global distribution.

5. Embed intelligence

Use intelligent models to assist engage customers and supply valuable insights from the info captured.

 

6. Deliver software on demand
Also referred to as software as a service (SaaS), on-demand software allows you to offer the newest software versions and updates around to customers—anytime they have,
