What is cloud computing, or cloud computing? It is a set of computers that work as if they were a single computer. Understand this concept!

 If you use common web applications such as social networks and webmail, you are already enjoying the benefits of cloud computing. A cloud services platform provides quick access to IT resources, both to support an operation in your company and to run a website that shares photos with millions of users. Let’s see more about what cloud computing is.

What is cloud computing?

Cloud computing – also called cloud computing – is a technique for sharing resources between computers, which are interconnected over the internet. There are several computers working together in an integrated way, but when you use it, it seems to be on a single machine.

So, when you access a photo stored on a cloud server, you may be using resources from multiple machines. It may be that even the file is being “assembled” with parts coming from different servers.

Cloud computing service is usually offered by specialized hosts. Thus, small and medium-sized companies do not need to know in depth what cloud computing is, invest in servers, or waste time on hardware maintenance and management.

By hiring cloud hosting, you acquire computing resources as needed for your application or for the functioning of your company. And the most interesting thing, you only pay for what you need, and you can change the amount of resources to more or less whenever you want.

How does cloud computing work?

The most important thing is to know that the cloud provides an easy way to access servers, storage, databases, and applications over the internet. See in this video a very nice explanation about what cloud computing is.

Cloud types

As you can imagine, the architecture of cloud computing is very flexible. Basically, we can implement and use three types of cloud computing. Let’s find out what they are:

Cloud (cloud)

The “normal” cloud is the one we hire from hosting providers such as Google, Amazon, or Microsoft. The cloud that we hire in this way is not allocated in our company, but in a data center in some (or several) place(s) in the world.

Through the internet, we can manage the entire environment through the control panel, increase or decrease the processing and storage capacity, etc.

But we don’t know where our accommodation is. This can be a security risk when storing important data. However, this model has the best cost-benefit, as you don’t need to invest in hardware, maintenance, or staff… and you still pay for exactly what you’re going to use.

Private cloud (private cloud)

A company can build its private cloud, using servers from its own park. Thus, in addition to total control over the infrastructure on which it is based, company policies (such as security) can also be considered. In fact, the security of sensitive data is one of the reasons why companies create their on-premises cloud instead of hiring one.

As it requires the acquisition of equipment, software, and staff training, the private cloud has a high cost. Microsoft, IBM, and HP are some companies that offer solutions for creating private clouds.

Hybrid cloud (hybrid cloud)

In the hybrid cloud, you have to work with the on-premises and “public” cloud together. In this case, companies store important data in local clouds, and what is publicly accessible in “public” clouds.

Hybrid clouds allow you to use the best of each of the private and “public” clouds. Therefore, this model is successful in companies.

In the case of a temporary need, for example, the hybrid cloud will help to unburden without the need for investment in hardware and services. But, here’s the tip: your performance is highly related to the quality of your implementation. Therefore, pay attention so that there are no problems passing data between one cloud and another.

What is the difference between a cloud server and cloud computing?

Despite the similar names, hiring a cloud computing is not the same as hiring a cloud server service. They are different things, and each one has its objective.

But do you know what the difference is?

The cloud server, as we explained earlier, is a form of hosting in which web applications are stored in a cloud computing environment. Therefore, the cloud server uses virtual machines to provide services in the cloud.

Cloud computing, on the other hand, is the set of technologies that make it possible to run applications distributed on different servers, sharing their resources (such as memory and processing). In other words, cloud computing technologies allow the existence of services such as the cloud server.

Here are some differences between them:

  • Cloud computing requires large processing and storage capacity. Cloud server, on the other hand, uses more space.
  • Cloud computing is typically used by large companies to process large amounts of data. Cloud servers, on the other hand, can be used by companies or individuals.
  • Cloud server has the main purpose of providing file storage and availability, while cloud computing mainly provides processing power (eg Big Data applications).

Hire hosting with those who understand the scratch

If you are looking for a good dedicated or shared server, we have a suggestion. Hostgator! _ It is a company with a tradition in hosting services, present all over the world. That is, the guys are aware of the subject.

And the infrastructure? There is no equal: There are several data centers those are always ready to host your application.

In short

We explain in this short post what cloud computing is. Also known as cloud computing, it is a technique where several different computers work together in an integrated way. But when you use it, it appears to be a single machine. We have also seen that cloud computing can be public, private or hybrid.
