Cloud computing – Definition and meaning
What is Cloud computing? Find out what cloud computing is and what advantages it offers companies.
Types of cloud computing
Cloud computing can be categorised into different models:
- Infrastructure as a Service (IaaS): Provides basic IT resources such as virtual machines and storage space.
- Platform as a Service (PaaS): Provides a platform on which developers can create and deploy applications without having to worry about the underlying infrastructure.
- Software as a Service (SaaS): Provision of software applications via the internet that are hosted by a cloud provider.
Challenges of cloud computing
Despite the numerous benefits, there are also challenges associated with cloud computing:
- Data security: sensitive data is stored in the cloud, which brings with it potential security risks.
- Dependence on providers: Companies could become dependent on a particular provider, which can lead to difficulties when migrating to other services.
- Wi-Fi dependency: The quality and speed of access to cloud services depends heavily on the internet connection.
Illustrative example on the topic: Cloud computing
Imagine a small start-up has decided not to host its accounting software itself, but to use a cloud service instead. In the initial phase, the company could set up an account with a SaaS provider within minutes and start using the software immediately without having to invest in expensive server hardware. As the company grows and more employees are added, it can simply book additional user licences. In addition, the software always remains up to date as the provider carries out regular updates. However, if the company decides to host the accounting software itself, this could be costly and time-consuming and could even cause difficulties during rapid growth. In this way, the example demonstrates the flexibility and efficiency that cloud computing can offer an organisation.
Conclusion
Cloud computing is a revolutionary technology that has changed the way organisations use and deliver IT services. With the ability to scale resources on demand, save costs and ensure secure access to data, cloud computing is an important consideration for organisations of all sizes. However, the challenges should also be carefully considered when introducing it.

Frequently asked questions
Cloud computing refers to the provision of IT resources via the internet, allowing companies to access flexible and scalable solutions. Instead of operating their own servers and hardware, they use services from cloud providers who provide infrastructure, platforms or software. This technology makes it possible to save costs and adapt resources as required.
Cloud computing works by providing resources via the internet. Users can access virtual machines, storage and software provided by a cloud provider via web applications. The underlying infrastructure is managed by the provider, allowing companies to focus on their core competences without having to worry about hardware and maintenance.
Cloud computing is used in numerous areas, including data processing, software development, data storage and backup as well as for hosting services. Companies use it to host applications, analyse data or scale their IT infrastructure. This flexibility and accessibility help companies to work more efficiently and react quickly to market changes.
The advantages of cloud computing include cost savings, as companies only pay for the resources they actually use. It also enables high scalability, allowing companies to quickly adapt their IT resources. Accessibility from anywhere and at any time improves collaboration and supports remote working. Security is also an important benefit, as cloud providers invest in advanced security measures.
There are several challenges with cloud computing, such as data security, as sensitive information is stored in the cloud. Companies could also become dependent on a particular provider, which makes it difficult to migrate to other services. In addition, the quality of the internet connection is crucial, as slow connections can impair access to cloud services.
IaaS (Infrastructure as a Service) provides basic IT resources such as virtual machines and storage. PaaS (Platform as a Service) provides a development environment in which developers can create applications without having to worry about the infrastructure. SaaS (Software as a Service), on the other hand, offers fully developed software applications via the internet that are hosted by the provider.
