what is Cloud computing

Cloud Computing is the concept of delivering on demand access to computer resources and data through the Internet. This means that users can pay only for what they use. As opposed to buying servers, software and hardware upfront then maintaining, upgrading and scaling it to meet increasing demands, cloud computing lets you scale up or down without changing anything else in the infrastructure. The cloud providers host the servers, storage, networks and application services related to the service. Users connect to the cloud using web browser based applications or APIs (application programming interfaces). Cloud computing offers several advantages over traditional forms of IT including scalability, flexibility, cost savings, and improved security. There are three types of clouds: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

There are three types of clouds: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

1. Cloud Computing

In recent years, cloud computing has become increasingly popular. Many users have realized that there are many advantages to using this type of service. One of the biggest benefits is the ability to access your data from anywhere. When you work at home, it’s inconvenient to carry files around with you. With cloud computing, you can store your data in the cloud and access it remotely (using mobile devices). Most cloud services offer both shared and dedicated plans as well as different storage capacities. There are even some free cloud accounts available.

2. SaaS/Software As A Service

With software as a service (SaaS), you pay only for what you use rather than paying for the whole thing upfront. This means that you don’t have to worry about maintenance and upgrades. You can install a program on multiple computers without worrying about compatibility issues. Most SaaS providers automatically update their programs so they are always compatible. You won’t have to spend time learning how to use the program.

3. PaaS/Platform as a Service

The platform as a service (PaaS) allows developers to create applications without having to learn the coding language used by the application. They can focus on writing code instead of trying to figure out how to operate the computer. The PaaS provider handles everything for the developer including operating costs. It hosts, supports, and maintains the server running the application.

4. IaaS/Infrastructure as a Service

Infrastructure as a service (IaaS) provides users with virtual servers where they can host their own websites, blogs, databases, email, etc. The user does not necessarily need any special skills to run the website; he or she pays only for the resources consumed. The provider offers a web space with enough disk space and RAM to handle all the traffic generated by the website. The provider then monitors the environment to ensure that it stays within the allotted limits.
