Cloud computing is spreading around the world, as it is an increasingly popular technology. The reasons are simple: it allows greater productivity and security in all jobs. However, did you know that there are different types of cloud computing? In this article, we will tell you everything you need to know about it, including what each one is for.


Types of Cloud Computing you need to know about

First and foremost, it should be noted that there are 4 types of Cloud Computing. We could say that they are the following: public clouds, private clouds, hybrid clouds, and multi-clouds. Similarly, it is essential to point out that there are 3 types of Cloud Computing services: Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS).

But what are the similarities between each? They all extract, pool, and share computing resources on a network. All clouds enable cloud computing, which is a system that runs workloads. Therefore, they usually include an operating system, a management platform, virtualization, or automation, among other elements.

However, there are also several differences. Let us tell you about them:


Public clouds

According to TechTarget, public clouds are usually created from an IT infrastructure external to the end-user. For example, some well-known providers are Google Cloud, Amazon Web Services (AWS), and IBM Cloud. Until some time ago, public clouds were run off-site.

However, today’s public cloud providers started offering these services in their customers’ on-premise data centers. So when do clouds become “public”? When environments are partitioned and become distributed among multiple users.


Private clouds

As for private clouds, they consist of cloud systems that are specifically targeted toward an end-user but can also be a group of them. This means that many clouds can become private clouds in cases where the IT infrastructure is intended only for one customer, in isolation.

However, it should also be noted that companies are now designing private clouds in third-party, off-premise data centers. In other words, private clouds no longer need to come from an on-premise IT infrastructure. And did you know that there are two subtypes corresponding to these clouds? They are:

  • Exclusive clouds. It is a cloud within a cloud. You can have an exclusive cloud in a public cloud, but also a private cloud. This happens in large enterprises. For example, the accounting department can have a dedicated cloud within the corporate private cloud.
  • Managed private clouds. In this case, customers create and use a private cloud that is managed by an external provider. This type is perfect for those companies that do not have the resources or skills necessary for companies to self-manage, as they rely on a specialized company.

Hybrid clouds

In this case, it is a mix of both of the above options. Google defines hybrid clouds as IT environments that are created in multiple environments and are connected via local area networks (LANs), wide area networks (WANs), APIs, or virtual private networks (VPNs).

And what are the characteristics of these clouds? Well, they are usually the most complex. A hybrid cloud, similarly to other hybrid models, is made up of a mix of elements. In this case, it usually has at least one private cloud and one public cloud. It is also possible to have two or more private clouds, two or more public clouds, and a virtual environment connected to a cloud, usually with an operating system.

This allows us to understand that IT systems are transformed into hybrid clouds when applications are moved to different environments. All these digital environments need to be managed as a single environment, through a platform that is integrated into the organization and management.



Finally, there are also multi-clouds. This is a specific type that consists of at least two cloud services. In this sense, at least two public or private cloud providers are provided. And it is important to clarify one thing: all hybrid clouds are multi-clouds, but not all multi-clouds are hybrid.

Only, they become hybrid when several clouds are connected through some integration. The digital multi-cloud environment can be created on purpose. One case occurs when sensitive data needs to be controlled. They can also be generated randomly, after using software not approved by the company.

So, you have seen that there are different cloud computing systems. No cloud is “better than another”, but it will always depend on what is needed in a company. In other words, all of them can be useful, depending on the different contexts. For this reason, it is key that you know what your intentions are when hiring this software. In short, we have analyzed the different types of cloud computing and what you need to take into consideration when opting for one of them. Keep this article handy for when you need to implement the cloud in your company!
