What is cloud hosting?

Cloud hosting: definition

With traditional hosting, a website runs on a specific server—shared with other customers or rented exclusively. With cloud hosting, computing power, memory, and storage come from a large network of servers. If one machine fails, another can take over.

The major providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud. There are also European providers such as Hetzner, IONOS, STACKIT, and OVHcloud, which operate data centers in Germany or the EU. The choice depends on data protection requirements, the services needed, and existing know-how, among other factors.

How cloud hosting works

Virtual servers, databases, and storage are provisioned via a management console or automatically via code. When the load increases, additional resources can be added automatically (autoscaling); when it decreases, they are released again.

Depending on the model, the provider takes on different levels of responsibility: with pure virtual servers, you take care of the operating system and updates yourself; with managed services, the provider handles part of that.

• IaaS: virtual servers, networks, and storage
• PaaS: managed platforms, e.g., for databases or containers
• Object storage for files, images, and backups
• Billing based on usage or at fixed monthly prices

Benefits and limitations of cloud hosting

Cloud hosting adapts to demand: an online store can handle traffic spikes—during promotions, for example—without expensive hardware having to be on standby permanently. Redundant systems and automated backups increase resilience.

However, costs can become hard to keep track of if resources aren't monitored. There are also questions about data protection and server location, especially with providers based outside the EU. And a cloud doesn't replace a security concept—configuring and updating your own application remains the operator's job.

• Scalable for traffic spikes and growth
• High availability thanks to redundant infrastructure
• Cost control and monitoring required
• Choose server location and data protection deliberately

Real-world example: moving to the cloud

A wholesaler runs its B2B portal on an old in-house server. Updates are laborious, and the portal slows down under heavy load. After moving to a cloud provider with a data center in Germany, the application and database run separately, backups happen automatically, and additional capacity is added when needed.

Whether cloud hosting makes sense depends on load, data protection requirements, and budget—sometimes a well-maintained single server is the leaner solution. Nano Concepts plans the right infrastructure, handles the migration, and, on request, takes care of monitoring and maintenance.
