What Is Cloud Computing?
In the simplest terms, cloud computing means storing and accessing data and programs on the internet instead of your computer’s hard drive. Cloud is just a metaphor for the Internet. It goes back in the days of flowcharts and presentations that represent the vast Internet-farm infrastructure of the Internet, but there is nothing other than a peep, white cumulus cloud, which accepts connections and floats information Pulls out.
Cloud Computing is not about what it is your hard drive. When you store or run data from a hard drive to the program, it is called local storage and computing. Everything you need is physically close to you, which means that it is fast and easy to access your data, either on a computer or on other local networks. Working off your hard drive How the computer industry works for decades; Some argue that it is still better than cloud computing, the reasons why I will soon understand.
The cloud is also not about a dedicated network attached storage (NAS) hardware or server space. Collecting data on a home or office network is not counted as the use of the cloud. (However, some NAS will allow you to remotely access things on the Internet, and there is at least one brand called Western Digital “My Cloud”, just to keep things confusing.
For this to consider “cloud computing“, you need to access your programs or your programs on the Internet, or at the very least, that data has been synced with other information on the web. In a big business, you can know what to know about the other side of the connection; As an individual user, you can never have an idea of what kind of data processing is being done at the other end. The end result’s the same: With an internet affiliation, cloud computing is done anyplace, anytime.
Consumer versus business
Let’s be clear here. We are talking about cloud computing because it affects individual consumers – those of us who sit back home or in small-to-medium offices and use the internet regularly.
When it comes to business, then there is a completely different “cloud”. Some businesses opt to implement Software-as-a-Service (SaaS), where the business subscribes to applications accessing the Internet. (Think Salesforce.com.) Is also Platform-as-a-Service (PaaS), where a business can create its own custom application for use by everyone in the company. And do not forget the powerful Infrastructure-as-a-Service (IaaS), where players like Amazon, Microsoft, Google, and Rackspace provide a backbone that can be “rented” by other companies. (For example, NetFlix provides you services because it is a customer of cloud services on Amazon.)
Of course, cloud computing is big business: the market produced $ 100 billion per year in 2012, which could be $ 127 billion by 2017 and $ 500 billion by 2020.
General cloud examples
Lines between local computing and cloud computing sometimes turn out very blurry. That’s because the cloud is part of almost everything on our computer these days. You can easily have a local piece of software (for example, Microsoft Office 365) which uses a form of cloud computing for storage (Microsoft OneDrive)
That said, Microsoft Web-based apps also provide a set of office online, which are only the only versions of the Internet, Word, Excel, PowerPoint and OneNote, without installing anything through your web browser. Are. This makes them a version of cloud computing (web-based = cloud).
Google Drive: This is a pure cloud computing service in which all storage is found online so it can work with the cloud app: Google Docs, Google Sheets, and Google Slides. The drive is also available only on desktop computers; You can use it on tablets like iPad or Smartphones, and there are also separate apps for Docs and Sheets. In fact, most of Google’s services can be considered cloud computing: Gmail, Google Calendar, Google Maps, and so on.
Apple iCloud: Apple’s cloud service is used primarily for the online storage, backup, and synchronization of your mail, contacts, calendar and more. All the data you need is available on your iOS, Mac OS or Windows device (Windows users must install the Icloud Control Panel). Naturally, Apple will not be able to overcome rivals: it provides a cloud-based version of its word processor (pages), spreadsheets (numbers), and presentations (kinauts) for use by any iCloud subscriber. Icloud is also the location where the iPhone users go for the use of my iPhone feature, which is all important when the handset disappears.
Amazon Cloud Drive: Storage on a large retailer is primarily for music, preferably the MP3s you buy from Amazon, and images – if you have Amazon Prime, you get unlimited image storage. Amazon Cloud Drive also keeps anything you buy for Kindle. This is essentially storage for digital in anything that is bought from Amazon, baked in all your products and services.
Hybrid services such as boxes, dropboxes, and fragrances say that they work in the cloud because they store a synced version of your files online, but they also sync those files with local storage. Synchronization is the cornerstone of the cloud computing experience, even if you access the file locally.
Similarly, this is considered cloud computing, if you have a community of people with different devices, who need the same data, then this work is for co-operation projects or only to keep the family in sync.
