What is Cloud Computing?

Cloud computing describes the provision of IT resources over the internet. Companies can thereby flexibly access storage, computing power, databases, and software applications without having to purchase and maintain local hardware. This outsourcing offers significant cost savings and enables rapid scaling as needed. Cloud computing thus provides access to a modern IT infrastructure that can be utilized with minimal effort.

Characteristics of Cloud Computing

On-demand self-service: Users can request and scale computing resources via APIs. This is often automated through various tools.
Broad network access: Cloud providers operate globally distributed servers that enable fast and location-independent delivery of services.
Resource pooling: Resources are dynamically distributed and shared. This allows multiple users to utilize the same hardware, ensuring optimal utilization.
Rapid elasticity: The infrastructure grows or shrinks dynamically to meet current requirements. This occurs automatically and ensures efficiency.
Measured service: Cloud services are often based on a usage-based billing model. This means customers only pay for the resources actually used, enabling transparency and control over costs.

Types of Cloud Deployment

Fundamentally, three types of cloud deployment are distinguished: public cloud, private cloud, and hybrid cloud:

In the public cloud, services are provided by providers such as AWS or Microsoft Azure (the so-called hyperscalers) over the internet. These providers operate all the necessary hardware and software.

Private clouds are exclusive to a single company. They offer higher security and can be hosted either on-premises or by a provider.

The hybrid cloud combines public and private cloud. It enables the storage of sensitive data in the private cloud while other services are provided in the public cloud.

Benefits of Cloud Computing

Cloud computing offers numerous benefits. Companies benefit from increased flexibility, as they can scale automatically and respond quickly to changing business requirements. Cloud computing also makes companies efficient and competitive, as they can leverage innovative technologies such as AI and data analytics. Additionally, the cloud enables companies to reduce IT costs while simultaneously increasing performance. It is therefore a key technology that helps companies modernize their IT infrastructure and establish a future-proof foundation.
