What Is Cloud Computing?

what is cloud computing

People seeking hosting solutions want to know, “what is cloud computing? When we talk about cloud computing, we are talking about the case where computing resources is considered a service that is delivered using a connection through a network, which is normally the Internet.

Unlike the traditional method of using local hardware or software, cloud computing makes use of the sharing of a pool of resources —physical or virtual, or even both. Another term that can be used to refer to cloud computing is ‘utility computing’.

Both of them work by allowing users access to computing resources instead of having to use specific equipment necessary to generate what they need by themselves.


Private Cloud

Private clouds make use of pooled services along with infrastructure that are stored on a private network —which could be either physical or virtual. This network can only be accessed by a single client, which results in better security as well as control.

However, private clouds are relatively less cost-efficient, since the enterprise will have to shoulder the costs of owning/renting as well as the maintenance of all the software and hardware necessary.

Public Cloud

In a public cloud, the cloud provider hosts the services as well as the infrastructure off-site and allows the clients access using public networks like the internet.

Public clouds are more cost-efficient because of how it can make good use of economies of scale. However, the high level of accessibility also means that public clouds are much more vulnerable compared to private clouds.

Hybrid Cloud

Hybrid clouds are made from the elements of both private and public clouds. By combining the best of both worlds, companies will get the maximum efficiency out of hybrid clouds.

This is done by using the public set-up for the less important operations that don’t require much security, while the private cloud is used for the highly sensitive operations.

By doing this, companies are assured of having the computing set-up that’s best suited for their needs without having to shoulder the expenses of using unnecessary features.

What Is Cloud Computing - Three Models of Cloud Computing

The model of the cloud computing depends on the service it offers. In general, there are three different models: Software as a Service [SaaS], Infrastructure as a Service [IaaS], and Platform as a Service [PaaS].

Software as a Service [SaaS]

SaaS is the most common model of cloud computing. SaaS refers to the hosting of applications in order to make them available via network connections to the customers. Most people have used this model even if they didn’t realize it, since a lot of web applications use SaaS.

Infrastructure as a Service [IaaS]

Just like the other categories of cloud computing, IaaS talks about the offering of virtual computing resources as a service delivered across a network. Specifically, IaaS refers to delivering hardware as the service.

The IaaS offerings include network connections, IP addresses, storage space, and virtual server space. The provider has control over several data centers wherein the pool of servers is distributed.

The resources will be pulled from the servers and the client will be given access to them. IaaS is perfect for enterprises due to its enormous benefits regarding businesses.

Platform as a Service [PaaS]

PaaS aims to provide developers the environment they need for building applications using the internet. Aside from the computing resources from an IaaS offering, the software and configuration required by the client to create the platform they need to create their applications will also be included in a PaaS package.

The best part about PaaS is that each package can be customized in order to create the perfect package for the client’s needs, meaning you can just get the features you need, for maximum cost-efficiency.

Another benefit of PaaS for enterprise owners is the ability for development teams to be able to coordinate together seamlessly regardless of the distance between members.
