What is cloud hosting

Much has been spoken about cloud hosting or hosting in the cloud, in recent years. It is true that the term confuses a lot of people, but we will explain in this article what is and how does a cloud hosting service.

Summary manner, we can say that the cloud hosting is a service that provides on the Internet one or more virtual servers are not located on a particular computer, but in a series of them. To distribute the resources of a single server between multiple computers, it is possible to lighten the load of each machine and win big in processing capacity. As the processing is distributed across multiple computers, you can even create supercomputers, with data processing capacity far greater than that which would be possible with a single server, even if it is a good dedicated server.

Now that we have an overview, we will better understand this concept, its benefits and how it works in practice.

Advantages of Cloud Hosting

In short, we can list the following advantages that the hosting cloud offers traditional hosting services:

  • Elasticity (increase or decrease) of resources
  • cost control (pay as you use)
  • processing capacity
  • Reduction of infrastructure costs

Let’s see in more detail each of the advantages which we have listed above.

Elasticity of resources 

One of the great benefits of hosting in the cloud is the ability to increase or decrease its resources, as they are needed. Imagine you have an online store, which has a constant traffic for most of the year, but has sudden increases in certain times, such as Black Friday or at the end of the year. If you use a traditional hosting service, your store may be off the air, if the server does not support some visits. To work around this, you need to upgrade or even hire a dedicated server, which will add a high fixed cost to its operation, and not necessarily will ensure the availability of your online store.

If you have a hosting cloud, you do not need to upgrade plan but sim expander the resources of their service, which is usually done in the hosting control panel itself. At the end of the era of high traffic, you can reduce the amount of resources it uses, returning to the previous level and also reducing service costs.

Cost control 

Besides the advantage of being able to expand and reduce the resources, the recovery in the cloud hosting is proportional to what is used. That is, you do not pay for more resources than necessary, as could happen on a dedicated server, for example.

In General, the hire service, you don’t hire a plan with a fixed price, as in a traditional hosting. Instead, you select an x amount of resources, such as memory, CPU, and disk space and pay by the hour, week or month, depending on the company. According to your demand, these resources can be increased or reduced, directly affecting costs.

Some companies differ in recovery model, and you can hire the hosting cloud as a prepaid or postpaid service. The prepaid model, you hire a given quantity of credits, which are consumed by the application when you use them. When the credits are over, you can choose to renew them automatically or manually. On postpaid, resources are being consumed and will be charged at the end of a predetermined fixed period (e.g., monthly). In both cases, you can track and manage to spend through the control panel of your hosting cloud.

Processing capacity

As mentioned at the beginning of the article, because it is a virtual computer that is distributed in various real computers, processing capacity and storage system can be expanded almost without limit. The advantages of this architecture are many, mainly for applications and systems that need to process a lot of information online.

To illustrate this capability, let us take as an example the Instagram app: when you publish a photograph, the image is sent and processed in a cloud server before being published for viewing of all. The same occurred with the comments and pickled in each photo. The system, therefore, depends on the processing “the cloud” for work. And this processing has to be done thousands of times a minute to meet the Instagram users, all over the world. Probably the Instagram wouldn’t work the way it is today if there were no cloud computing.

This same cloud processing logic is used in thousands of other applications, such as Gmail, Dropbox, online image editing programs, games and much more!

Cheapening IT infrastructure 

This is a little different from that mentioned above, but no less important. Many companies maintain on their servers to store data and systems of internal use and cannot be accessed by anyone outside the enterprise. An internal network (intranet), for example, works this way. This infrastructure of servers and networking equipment needs maintenance, is to keep the systems updated and running, is to make upgrades and equipment improvements. In this case, the company will need to contact professionals to maintain this network and internal servers. These professionals can be employees of the company or outsourced. Whatever the model, there will be a cost to keep professionals and equipment, which can be quite high, depending on the structure of the company.

On account of this high cost, many companies end up opting to migrate your internal systems for a private cloud, which is available on the internet, but can only be accessed using the business’s credentials. In this new scenario, the company reduces the cost of equipment, which will be borne by the hosting service provider cloud, and also reduces the cost of specialized professionals, for the maintenance and upgrade of the servers will also be made by the cloud provider. Of course, the company will continue looking for professionals to administer your new virtual infrastructure, but in the end, there will be savings.

Also, the company network can be accessed by employees who have located anywhere in the world, that they have the proper credentials to do so. This facet of cloud also allows the collaborative work is possible regardless of the location of employees. This last feature is very used in Office programs and editing of documents, such as the Google Drive and Dropbox, which allow multiple people to edit the same document simultaneously.
