Cloud computing means computers are staked together and then those staked computers are available online for everyone to use whenever they want. You can pay for whatever the resource that you use. You don’t need to pay more and less. You pay exactly for what you use. If you buy a computer and keep it in your office, you need to pay for whole hours if you don’t use it also. If you build the equivalent computer in cloud, you just need to pay whenever you use it.
Cloud computing is not only for building(Assembling) computers, its also available as specific services that usually done by physical computers in your premises. For example, If you want to share your voice, text or video with others online, you just need to have a web server which can serve voice, text and video. Instead of hosting those kind of servers in your premises, you can build a simple web server with the specification that are required in cloud.
Cloud computing is to deliver the various computing services such as Servers, Databases, storage, Software, Networking, analytics and many more over internet. Companies who offers these kind of services are called as cloud service providers. They typically charge for cloud services based on your usage which is similar to how we are billed for the water and electricity.
Cloud computing uses
You may be already using cloud computing without your awareness. For example, we have been using email services since long time. We are sending and reeving emails with the help of email servers which work behind the scenes. Similarly, you may be using file sharing services to store your important data within cloud accounts(ex: iCloud, Googe drive…etc). Now, the services are increased exponentially and proving all the kinds of services that are provided by physical computers earlier.
If you want to develop a new application or an app, you need to have certain server with certain configuration. If you don’t have the required configuration in your personal laptop, you can create a powerful computer or server in few minutes using cloud services. You can launch the instance to use it for 1-2 hours. You will be billed only for 2 hours. Rest of the time, the instance can be shutdown. You won’t be billed when your instance in in shutdown mode. This is one the main advantage with cloud computing.
Here are some of the things you can do with the cloud computing:
- Create new apps and services
- Store, back up and recover data
- Host websites and blogs
- Stream audio and video
- Deliver software on demand
- Analyse data for patterns and make predictions
Cloud computing – Top benefits
- Global scale
There are 3 types of cloud services, they are are
- Infrastructure as a service
- Software as a service
- Platform as a service
