Cloud Computing - Definition & Descriptions

According to Wikipedia?

Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each location being a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a "pay-as-you-go" model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users.

From <https://en.wikipedia.org/wiki/Cloud_computing>

According to IBM website?

Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.

Compared to traditional on-premises IT, and depending on the cloud services you select, cloud computing helps do the following:

·         Lower IT costs: Cloud lets you offload some or most of the costs and effort of purchasing, installing, configuring, and managing your own on-premises infrastructure. 

·         Improve agility and time-to-value: With cloud, your organization can start using enterprise applications in minutes, instead of waiting weeks or months for IT to respond to a request, purchase and configure supporting hardware, and install software. Cloud also lets you empower certain users—specifically developers and data scientists—to help themselves to software and support infrastructure.

·         Scale more easily and cost-effectively: Cloud provides elasticity—instead of purchasing excess capacity that sits unused during slow periods, you can scale capacity up and down in response to spikes and dips in traffic. You can also take advantage of your cloud provider’s global network to spread your applications closer to users around the world.

According to Microsoft website?

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 cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.

According to Google website? 

What is Cloud Computing? 

Understanding the types of cloud computing resources can be time-consuming and costly. Enterprises need to buy physical servers and other infrastructure through procurement processes that can take months, and support the architecture of cloud computing. The acquired systems require a physical space, typically a specialized room with sufficient power and cooling. After configuring and deploying the systems, enterprises need expert personnel to manage them. 

This long process is difficult to scale when demand spikes or business expands. Enterprises can acquire more computing resources than needed, ending up with low utilization numbers. 

Cloud computing addresses these issues by offering computing resources as scalable, on-demand services. Learn more about Google Cloud, a suite of cloud computing service models offered by Google.

According to Investopedia website? 

What Is Cloud Computing? 

Cloud computing is the delivery of different services through the Internet. These resources include tools and applications like data storage, servers, databases, networking, and software. 

Rather than keeping files on a proprietary hard drive or local storage device, cloud-based storage makes it possible to save them to a remote database. As long as an electronic device has access to the web, it has access to the data and the software programs to run it. 

Cloud computing is a popular option for people and businesses for a number of reasons including cost savings, increased productivity, speed and efficiency, performance, and security. 

KEY TAKEAWAYS

·         Cloud computing is the delivery of different services through the Internet, including data storage, servers, databases, networking, and software.

·         Cloud storage has grown increasingly popular among individuals who need larger storage space and for businesses seeking an efficient off-site data back-up solution.

·         Cloud-based storage makes it possible to save files to a remote database and retrieve them on demand.

·         Services can be both public and private—public services are provided online for a fee while private services are hosted on a network to specific clients.

·         Cloud security has become an increasingly important field in IT. 

Understanding Cloud Computing 

Cloud computing is named as such because the information being accessed is found remotely in the cloud or a virtual space. Companies that provide cloud services enable users to store files and applications on remote servers and then access all the data via the Internet. This means the user is not required to be in a specific place to gain access to it, allowing the user to work remotely. 

Cloud computing takes all the heavy lifting involved in crunching and processing data away from the device you carry around or sit and work at. It also moves all of that work to huge computer clusters far away in cyberspace. The Internet becomes the cloud, and voilĂ —your data, work, and applications are available from any device with which you can connect to the Internet, anywhere in the world. 

Cloud computing can be both public and private. Public cloud services provide their services over the Internet for a fee. Private cloud services, on the other hand, only provide services to a certain number of people. These services are a system of networks that supply hosted services. There is also a hybrid option, which combines elements of both the public and private services.

According to javatpoint website? 

What is Cloud Computing? 

The term cloud refers to a network or the internet. It is a technology that uses remote servers on the internet to store, manage, and access data online rather than local drives. The data can be anything such as files, images, documents, audio, video, and more. 

There are the following operations that we can do using cloud computing:

·         Developing new applications and services

·         Storage, back up, and recovery of data

·         Hosting blogs and websites

·         Delivery of software on demand

·         Analysis of data

·         Streaming videos and audios

Why Cloud Computing? 

Small as well as large IT companies, follow the traditional methods to provide the IT infrastructure. That means for any IT company, we need a Server Room that is the basic need of IT companies. 

In that server room, there should be a database server, mail server, networking, firewalls, routers, modem, switches, QPS (Query Per Second means how much queries or load will be handled by the server), configurable system, high net speed, and the maintenance engineers.

To establish such IT infrastructure, we need to spend lots of money. To overcome all these problems and to reduce the IT infrastructure cost, Cloud Computing comes into existence. 

From <https://www.javatpoint.com/cloud-computing-tutorial>

According to w3schools website? 

Cloud Computing has become the buzzing topic of today's technology, driving mainly by marketing and services offered by prominent corporate organizations like Google, IBM & Amazon. Cloud computing is the next stage to evolve the Internet. Though for some people, "Cloud Computing" is a big deal, it is not. In reality, cloud computing is something that we have been using for a long time; it is the internet facility, along with the associated standards that provide a set of web-services to users. When users draw the term 'Internet' as a "cloud", they represent the essential characteristics of cloud computing. 

From <https://w3schools.in/cloud-computing/>

Effect of Cloud on human lives 

·         The application became cheaper, easier to find, and use.

·         The new application becomes more comfortable to develop & create based on a standard modular part.

·         Cloud will provide new social services by connecting through social networks.

·         Lessen the usage of proprietary operating systems in our daily computing.

·         Connection to the cloud can be made whenever we want 

From <https://w3schools.in/cloud-computing/> 

Why this cloud technology? 

The small and extensive IT companies follow the old traditions of managing IT infrastructure, i.e., server room, to keep all the details and maintain that server. In a word, it is a server room consists of database servers, mail server, firewalls, routers, switches, QPS (Query per second) & Load handler, and other networking devices along with server engineers. To provide such IT infrastructure, a huge amount of money has to spend. So, to reduce the IT infrastructure cost, Cloud Computing technology came into play. 

From <https://w3schools.in/cloud-computing/> 

How cloud computing works? 

The cloud has to be divided into different layers. These layers are the front-end and back-end layers. The Front-end layer is that part of the cloud with which users can interact with. For example, when we log in to our Gmail account, we see the UI (user interface) where everything works on event-driven buttons and graphics. Similarly, the software also runs in the front end of the cloud. Again, the back-end comprises hardware as well as software that delivers the back-end data from the database to the front end.

According to Amazon website? 

What is cloud computing? 

Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS). 

From <https://aws.amazon.com/what-is-cloud-computing/>

According to Oracle website? 

What is cloud computing? 

Cloud computing and associated solutions provide access through the web to computing resources and products, including development tools, business applications, compute services, data storage, and networking solutions. These cloud services are hosted at a software vendor’s data center and managed by the cloud services provider or onsite at a customer's data center. 

From <https://www.oracle.com/au/cloud/what-is-cloud-computing/> 

Cloud computing defined 

In simple terms, cloud computing allows you to rent instead of buy your IT. Rather than investing heavily in databases, software, and hardware, companies opt to access their compute power via the internet, or the cloud, and pay for it as they use it. These cloud services now include, but are not limited to, servers, storage, databases, networking, software, analytics, and business intelligence. 

Cloud computing provides the speed, scalability, and flexibility that enables businesses to develop, innovate, and support business IT solutions. 

From <https://www.oracle.com/au/cloud/what-is-cloud-computing/> 

Cloud computing basics 

When a company chooses to “move to the cloud,” it means that its IT infrastructure is stored offsite, at a data center that is maintained by the cloud computing provider. An industry-leading cloud provider has the responsibility for managing the customer’s IT infrastructure, integrating applications, and developing new capabilities and functionality to keep pace with market demands. 

For customers, cloud computing offers more agility, scale, and flexibility. Instead of spending money and resources on legacy IT systems, customers are able to focus on more strategic tasks. Without making a large upfront investment, they can quickly access the computing resources they need—and pay only for what they use.

According to techtarget website? 

The name cloud computing was inspired by the cloud symbol that's often used to represent the internet in flowcharts and diagrams.

According to salesforce website? 

What is the cloud? 

Moving to the cloud. Running in the cloud. Stored in the cloud. Accessed from the cloud: these days is seeming like everything is happening “in the cloud”. But what exactly is this nebulous concept? 

The short answer is that it's somewhere at the other end of your internet connection – a place where you can access apps and services, and where your data can be stored securely. The cloud is a big deal for three reasons: 

1.      It doesn't need any effort on your part to maintain or manage it.

2.      It's effectively infinite in size, so you don't need to worry about it running out of capacity.

3.      You can access cloud-based applications and services from anywhere – all you need is a device with an internet connection. 

From <https://www.salesforce.com/in/learning-centre/tech/cloudcomputing/> 

How cloud computing works? 

With a cloud app, you just open a browser, log in, and start working. 

That means a field sales representative using cloud-based CRM can get all the information they need from their mobile device. Contact notes can be updated in real time so they are always fresh and complete and available to others – no more waiting to get back to the office to type it in. And sales managers know exactly which deals will close and when, from their desktop machines in their offices, or their tablets or phones when they are out and about.

According to sap website? 

Cloud computing has arrived, and everyone is interested in learning more. Your users and customers are used to their personal mobile applications, like Facebook and Google Docs, where they can interact and work anywhere, anytime. But there is much more behind cloud computing than just a modern web interface. Great response time, data storage, information access, reliability, and security are all vital to any business looking into a possible “move to the cloud.” More than likely your peers have told you of their success with cloud computing and how they have the most current technology, much more flexibility, or lower IT costs.
