Cloud computing describes the provision of IT resources over the Internet. This allows companies to 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 used with minimal effort.
Features of cloud computing
- On-demand self-service: Users can request and scale computing resources via APIs. This often happens automatically through various tools.
- Broad network access: Cloud providers operate globally distributed servers that enable fast and location-independent provision 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 happens automatically and ensures efficiency.
- Measured service: Cloud services often operate on a usage-based billing model. This means customers only pay for the resources they actually use, providing 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 over the Internet by providers such as AWS or Microsoft Azure (the so-called hyperscalers). 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 locally 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.
Advantages of cloud computing
Cloud computing offers numerous advantages. Companies benefit from increased flexibility as they can automatically scale and quickly respond to changing business requirements. Cloud computing also makes companies efficient and competitive by allowing them to use innovative technologies such as AI and data analytics. Additionally, the cloud enables companies to reduce IT costs while increasing performance. Thus, it is a key technology that helps companies modernize their IT infrastructure and position it for the future.
