Hosting provider

A company that provides the infrastructure and computing resources required to host websites, applications, and data on the internet.

A hosting provider is an entity that maintains physical servers in data centers and leases their resources to clients. The provider is responsible for hardware maintenance, high-speed network connectivity, and ensuring the physical and digital security of the infrastructure.

How it works

Users select a service model—such as Shared, VPS, or Dedicated—and upload their application code or data to the provider's infrastructure. The provider manages hypervisors, hardware firmware updates, and environmental controls like cooling and power redundancy. Data is accessed via an IP address linked to a domain name through DNS records.

Hosting services are utilized for web applications, corporate email systems, database storage, and CI/CD pipelines. The selection of a provider is typically governed by a Service Level Agreement (SLA), which specifies the guaranteed uptime and support response times.

  • Shared hosting: Multiple users sharing the resources of a single physical server.
  • VPS (Virtual Private Server): Virtualized server environments with dedicated CPU and RAM allocations.
  • Dedicated Server: Full lease of a physical machine for high-load projects.

Standard availability for Tier III certified data centers is 99.982%, limiting unplanned downtime to approximately 1.6 hours per year.
