IaaS

Infrastructure as a Service

IaaS (Infrastructure as a Service) is a cloud computing model in which basic IT infrastructures such as computing power, storage space, network resources and virtual machines are provided via the internet. Instead of buying and managing their own physical servers and hardware, companies can rent and scale the infrastructure they need from an IaaS provider as required.

Functions of IaaS

Virtual machines: Users can create and manage virtual servers that function like physical servers but based on the provider’s hardware.
Storage solutions: IaaS offers flexible storage options that scale as needed, from simple disk storage to complex data storage solutions.
Network resources: Users can manage network components such as firewalls, load balancers and IP addresses to deliver their applications securely and efficiently.
Computing power: IaaS providers make scalable computing resources available, enabling companies to adjust the required performance depending on the workload.

Advantages of IaaS

Cost efficiency: Companies do not have to make expensive investments in hardware and instead only pay for the resources they actually use.
Flexibility: IaaS enables companies to quickly adapt their infrastructure to changing requirements, whether by adding resources at peak times or reducing them when utilization is lower.
Scalability: IaaS platforms offer almost unlimited scalability, allowing companies to scale their infrastructure up or down as needed.
Maintenance-free: The IaaS provider takes over the maintenance and updating of the underlying hardware and infrastructure, which simplifies IT operations.

Examples of IaaS

The best-known IaaS providers include Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP). These platforms offer a wide range of infrastructure services that companies of different sizes and industries can use.

Use cases of IaaS

IaaS is ideal for companies that require flexible and scalable infrastructure solutions, e.g. for hosting websites, performing high-performance computing, storing large amounts of data or providing development and test environments.
