What exactly is meant by cloud and what kind of services take advantage of this technology? In this article, What is cloud and how does it work?, we will delve into an increasingly timely topic and see what services fall under the definition of cloud.

To better understand what cloud is and how it works, we will not just give you a definition, but specifically go over practical applications ranging from cloud storage and hosting services to cloud gaming. To begin, let’s take a look at what cloud means and what kinds of services the term can be associated with.

What is “cloud” and how does it work?

Chances are you have already heard of cloud computing, cloud storage, and cloud services in general. But what is cloud? What is the meaning of this term?

The literal meaning of the word cloud is cloud, and by this term we refer to a global network of servers that can be used as one large system. Initially, the word cloud referred precisely to the servers and network that constituted the Internet and was represented precisely as a cloud.

Now the term cloud refers specifically to cloud computing, or computing services that are provided over the Internet.

What Is Cloud

In simple terms, the cloud represents everything that is accessible through the Internet, it can be files but also applications and programs, that can be accessed remotely.

Let’s see what is the meaning of three main applications of the cloud: cloud storage, cloud computing and cloud hosting, to better understand what the cloud is.

What does cloud storage mean?

One of the most well-known applications of the cloud is cloud storage or cloud archiving services. Services of this type offer cloud space available to users, and this space can be used to store photos, documents, and make real backups of one’s files.

So when we talk about data saved in the cloud, we are referring to data saved on a server and accessible from any device.

What Is Cloud Backup

An easy-to-understand example to better understand the cloud and its potential is email. The emails you access with services such as Gmail are stored in a server and can be accessed by computers and mobile devices, rather than being stored on a single device.

Benefits of cloud storage

Cloud data storage allows us to have access to files at any time without being constrained to using a single device.

This allows us, for example, to save photos from our smartphone in the cloud and be able to access them from any other device that has Internet access.

Storing files in the cloud also means we can share them with other people, and this allows us, for example, to collaborate with others by editing the same file.

Let’s not forget that cloud storage of data is not only useful for personal use, but is equally important for a business. Specifically, cloud storage makes it possible to share files without having to attach them via email, thereby also reducing problems due to attachment size limitations.

In addition to improving collaboration and productivity, cloud storage is mainly used to create reliable backup systems.

Disadvantages of cloud storage

The limitations of cloud storage are due to the nature of the service. In fact, the main limitation is that it depends on an Internet connection. Access to files depends solely on the connection.

Secondly, although rather than a limitation, we speak of a critical point, there is the issue related to data security. In light of the General Data Protection Regulation (GDPR) you need to make sure that the provider you choose to back up your website/company data is compliant with the regulation.

What does cloud computing mean?

Cloud computing refers to the distribution of computing power, software, analysis systems or resources devoted to storage, which is done through the Internet.

The power and innovation of cloud services comes precisely from what is called the scalability of this type of infrastructure. What does it mean? The greatest advantage of cloud services is precisely that of being able to have resources available as needed.

Being able to have more or less computing power or storage space means having greater flexibility and also having costs in accordance with the actual use of resources.

What does cloud hosting mean?

In this article we will discuss what cloud is and its applications in general. If you want to learn more about the benefits and applications of cloud hosting check out our articles on comparing Cloud hosting vs shared hosting and on the Cloud server hosting price.

Alongside Web hosting providers also make cloud hosting services available. On SupportHost for example, we offer solutions for VPS cloud hosting.

But what are the advantages of the cloud in hosting?

What Is Cloud Server

Choosing a cloud plan means being able to rely on a cluster of servers that is used to create virtual machines.

In addition to providing hardware redundancy and thus ensuring greater uptime, a cloud hosting solution is also more flexible. The advantage, in fact, is that hosting resources can be increased without having to wait for the time it takes to transfer files from one physical server to another.

The result is that a cloud hosting plan, in addition to offering more resources than a shared hosting or a semi-dedicated hosting, is also a more flexible solution.

What is the cloud for?

Now that we have clarified what the cloud is, let’s look at its uses specifically. The applications of a cloud infrastructure can be varied; here is a non-exhaustive list of some practical examples:

  • Data storage and management, often referred to as cloud storage or cloud archiving
  • website hosting
  • Content distribution: email services, streaming, cloud gaming
  • Tools and applications accessible by multiple users and from multiple devices
  • development environments
  • Data analysis systems and big data processing
  • database
  • internet of things
  • machine learning.

To better understand the cloud, what it is and how these services work specifically, let’s look at some real-world examples of cloud computing, storage, and cloud gaming.

Cloud computing services

To better understand the cloud, what it is and how it works, let us see what different types of cloud computing exist.

Types of cloud computing include: private cloud, public cloud, hybrid cloud, and multicloud. Public clouds are services provided by a company, the provider, to an end user.

What Is Cloud Microsoft Azure

Public cloud providers include Amazon AWS, Microsoft Azure, Google Cloud, IBM Cloud, Alibaba Cloud, and Oracle.

We speak of private clouds in reference to infrastructure reserved for a single end user. In this case, the infrastructure may also be managed, in other words, the configuration and management is outsourced to external providers. Somewhat like what happens with a web hosting provider when you choose a managed server.

Hybrid clouds are environments formed by private and public clouds connected to each other. When in addition to being formed by multiple cloud services, the infrastructure is provided by different providers, it is called multicloud.

Cloud storage services

Cloud storage systems keep down the costs that would be required to purchase, maintain and manage the hardware needed to store data.

The main application of cloud storage is precisely to back up data. Moreover, unlike a backup to a physical medium such as a backup to a hard disk, the advantage of cloud storage is precisely that it provides greater data security.

In fact, in this case, copies are stored in a different location than the original data.

At the same time, the greatest advantage is the availability of the data, which being in the cloud is therefore accessible at any time and from anywhere.

What Is Cloud Amazon Aws

Let’s look at some examples of cloud storage services, we will discuss some of the most popular storage services, but remember that there are also services designed for data backup and recovery (disaster recovery), running cloud applications and machine learning, such as Amazon S3, which is part of the services Amazon AWS.
