Today, with everything happening so quickly online, cloud computing is playing an essential role in transforming many sectors. It has altered how various groups, persons and organizations save, retrieve and control their information. With cloud computing, people can easily share documents or run and manage more involved applications on a flexible and budget-friendly platform.
What does Cloud Computing refer to?
Through cloud computing, computing services like servers, storage, databases, networking, software, analytics and intelligence are provided online (“the cloud”) to help users accomplish things faster, access what they need easily and save on costs. Enterprises can use anything from software applications to internet storage by renting it from a cloud provider, rather than investing in their own computers and servers.
In other words, rather than saving data and programs on your computer’s hard drive, you do it through the Internet.
Types of Cloud Computing
There are three main types of cloud computing, each suited to different business needs:
| Type | Description | Examples |
| IaaS | Infrastructure as a Service. Provides virtualized computing resources over the internet. | Amazon Web Services (AWS), Microsoft Azure |
| PaaS | Platform as a Service. Offers hardware and software tools over the internet. | Google App Engine, Heroku |
| SaaS | Software as a Service. Delivers software applications over the internet on a subscription basis. | Gmail, Dropbox, Salesforce |
Ways to Set Up Cloud Services
Companies can use cloud services in numerous ways, based on their requirements.
- Public Cloud offers services accessible over the internet to all users (for example, AWS or Microsoft Azure).
- A Private Cloud is created solely for an organization to use. Provides more control and extra security.
- On a Hybrid Cloud, public and private clouds are merged, so data and applications can be moved from one to the other.
