How to securely store data in the cloud? Check what is the Internet cloud and how to use virtual disks!
Internet Cloud - Server

The digitization of many areas of life contributes to the increased demand for IT services. Collecting more and more data requires space to store it. Stationary private PCs or corporate servers are not always up to the task.

In addition, collections of documents, multimedia files and other such data are available to the user only from the computer on which they have been deposited. Both of these limitations are lifted by the cloud.

What is a cloud?

The cloud is defined in several ways. On the one hand, it is a service that is provided by the ISP or any third party. On the other hand, it is a virtual data storage that can be used by a company or a private client after creating an account and accessing the server. It is also a data processing model defined by the software provided by the service provider.

In each of these definitions, the cloud is an alternative to data carriers such as a hard drive, server or pen drive, with the difference that access to the information stored on it is possible from anywhere in the world.

It is enabled by the Internet, through which data is uploaded to the server, viewed and processed on it, as well as downloaded. For such actions to be possible, the user must access the files in the cloud by logging into the account.

How does the cloud work?

The principle of cloud computing is simple. Any company that has capacious and fast servers with access to high-quality Internet with adequate computing power can rent space on them to external customers.

In most cases, such a service is associated with e-mail or the operating system and includes specific service packages.

By creating an account in the cloud such as Dropbox, OneDrive by Microsoft or Google Drive, the customer receives a specific place that he can use for free.

If the cloud capacity is too small for him, the service provider usually offers the opportunity to buy additional space on the server. Fees in the form of a subscription are not high and amount to a few or several zlotys a month.

The advantage of using the cloud is access to data from anywhere in the world. You can log in to your account via any mobile device such as a smartphone, tablet, laptop or desktop computer.

At the same time, the user does not have to invest in and manage the infrastructure. Any failure or compromised data security are problems whose solution lies with the service provider. To store information in the cloud and be able to use it, the user only needs the appropriate software.

Types of internet clouds

IT clouds are created and made available by corporations or providers generally available to any interested user. This is the basic criterion for the division into types of clouds. They are currently divided into:

  • private clouds - created inside the corporation and intended for its employees,
  • public clouds - data storage space is provided in them by generally available providers such as Microsoft Azure, Google Cloud or Amazon Web Services. It is available to companies and individuals,
  • hybrid clouds - combining the principles of functioning of private and public clouds,
  • multicloud - allowing one user to use cloud services from different providers.

In addition to the types of computing clouds, there are also various models of them. In practice, this means a specific range of services and access to specific functions that users can use.

The simplest is the so-called collocation, which includes only renting a place in a server room with access to electricity and air conditioning. The person renting the space in the cloud pays for the maintenance of the equipment.

Other more advanced models include:

  • IaaS (Infrastructure as a Service) – infrastructure as a service, i.e. providing the client with hardware, software and servicing,
  • PaaS (Platform as a Service) - platform as a service, i.e. the sale of a set of applications without the need to purchase hardware or programs,
  • SaaS (Software as a Service) - software as a service, i.e. providing the client with selected program functions tailored to his needs,
  • CaaS (Communication as a Service) – communication as a service, i.e. access to a telecommunications platform,
  • IPaas (Integration Platform as a Service) – an integration platform as a service enabling the integration of various cloud services.

What is cloud data storage?

Storing information in the cloud is not much different from uploading it to an external hard drive. The difference, however, is that the user's cloud drive is virtual and not physically available. It is located on the server of the service provider, often located hundreds of kilometers away.

On the other hand, the data transfer itself takes place remotely, and only the Internet access and the appropriate application are needed for its implementation.

The client shares the server with other people, having a designated disk space at his disposal. It can save and store files, backup valuable data or use the functions available in the application.

How to store data in the cloud?

Working in the cloud has many advantages. Four of the most important are:

  • thanks to the cloud, you can free up space on your computer, especially if you collect large collections of films, photos or graphic designs,
  • by uploading data to the cloud, you can share it with other people without the need to physically burn it to discs or other data carriers. Only you and the people you assign it to have access to your files,
  • space in the cloud allows you to store data backups, thanks to which you will not lose them in the event of a network or computer failure,
  • you do not have to worry about the security of your data, because it is provided by the network operator.

The use of the cloud by company employees usually raises the question of whether the data stored in it is safe. This is important due to the current provisions of the GDPR. Although the administrators, by definition, ensure maximum security of information, it can also be encrypted.

As with any service, access to the cloud is regulated by a contract. Therefore, before starting cooperation with the operator, it is worth getting acquainted with the principles of data protection, the responsibility of the service provider in this regard or the technical side of setting up and using the account.

How to use cloud computing?

Although the concepts of cloud computing and Internet are often equated, in reality the two services are slightly different from each other.

The Internet cloud is a network that is mainly used to collect and store data, back up your data. On the other hand, cloud computing provides the potential necessary to process large amounts of data. The purpose of using such a service is to transfer most of the tasks related to IT support to an external server.

Since it takes the brunt of all operations, its computing power should be high. At the same time, the client computer does not have to meet high requirements. You can store the saved data in the cloud, check it, and share it from your smartphone.
