Understanding What is Cloud Computing
Learn the basics of cloud computing, its benefits, and how you can get started as a beginner.
What exactly 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), Microsoft Azure, or Google Cloud Platform.
How does cloud computing work?
Cloud computing provides shared computing resources, software, and information to computers and other devices on demand. It works by using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. Cloud providers run these services in data centers around the world to ensure redundancy, reliability, and security.
What are the benefits of using cloud computing?
- Cost Savings: Cloud computing eliminates the capital expense of buying hardware and software, setting up and running on-site datacenters.
- Speed: Most cloud services are provided on-demand, so vast amounts of computing resources can be provisioned in minutes.
- Global Scale: The benefits of cloud computing services include the ability to scale elastically, delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when they are needed, and from the right geographic location.
- Performance: The largest cloud services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware.
- Reliability: Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network.
What are some common uses of cloud computing?
From email services to word processing and enterprise applications, cloud computing is used for everything from migrating existing applications to deploying new applications. Here are a few examples:
- Data Storage: Store, back up, and recover any amount of data at a cost-effective price.
- Streamlined Operations: Use cloud-based workflow and file sharing apps to help teams make updates in real time and gives them full visibility of their collaborations.
- Analytical Insights: Unify your data across teams, divisions, and locations in the cloud. Then you can use cloud services, such as machine learning and artificial intelligence, to uncover insights for more informed decisions.
How can a beginner get started with using cloud computing services?
To get started with cloud computing, beginners should focus on understanding the basic principles of cloud computing and what it can do. Choose a service model and a provider that offers tutorials and beginner-friendly platforms, and consider starting with a simple project, such as using cloud storage or joining a cloud-based office suite to understand the basic functionalities.
