Data processing in a cloud: Cloud computing

Cloud computing is the provision of various services via the Internet, such as storage space, software, databases, networks and analytics. It enables users to securely access a shared pool of resources from anywhere in the world.

The term "cloud" refers to the environment in which cloud computing operates. The network architecture is Internet-based. It can be used in its own IT network (private cloud).

However, there is also the option to outsource IT infrastructure and operation to an external cloud provider (cloud services). Greater IT resources than in-house IT expansion (self-service) are promptly offered by the public cloud.

Unlike decentralised edge computing, cloud computing is often outsourced to a central server. In addition to the conventional types of cloud computing, there can, however, also be a hybrid solution consisting of both network structures (hybrid cloud).

How does cloud computing work?

With cloud computing, companies can store their resources on remote servers instead of on local computers or hardware. These remote servers are part of a network known as the "cloud".

Data for users and software applications are stored and managed via cloud storage. In the case of an external data centre from third-party providers, the data is hosted in its own access-restricted networks.

In this way, companies can manage their data from any device connected to the Internet. Special software applications do not necessarily have to be installed on every device. Often, just a simple Internet browser is sufficient.


What advantages does cloud computing offer?

For companies, cloud computing offers more flexibilityscalabilitycost savings and increased security. Companies can store large amounts of data without investing in hardware or IT infrastructure. 

It also allows users to access files from any location with Internet access. Among other things, this can improve opportunities for collaboration over long distances.

Where is the cloud used?

Companies use cloud computing for a variety of applications. This includes, for example: 

  • File storage and sharing
  • Web hosting
  • Database management
  • Analytical tools
  • Virtual machines

Numerous industries have decided to move their operations to the cloud. The aim is to reduce costs and increase efficiency. Private individuals also use cloud-based services such as music and video streaming, online games and social networks.
