Web hosting is a technology service that stores a website's files, code, media, and data on internet-connected servers so people can access it through a browser. A web host provides the computing resources and network connection that keep a site available online. Hosting is separate from a domain name, although the two must be connected through DNS for a website to work.

What Is Web Hosting?
Web hosting stores a website's files, code, media, and data on internet-connected servers so people can access it in a browser. A host supplies the computing power, storage, and network connection needed to keep a website or web app online. Hosting differs from a domain name, such as example.com, which is its human-readable address.
How Web Hosting Works
Web hosting connects a domain name to software running on a server. DNS directs visitors to the host, and HTTPS encrypts data between the browser and application.
- Register a domain name and choose hosting.
- Point the domain's DNS records to the host.
- Deploy website files, code, databases, and configuration.
- A browser requests the domain over HTTPS.
- The server returns a static page or runs code to create a response.
Types of Web Hosting
The right type depends on the control, isolation, and operational help an application needs.
| Type | Resources and control | Best fit |
|---|---|---|
| Shared hosting | Resources shared with other sites, limited control | Simple, low-traffic websites |
| VPS hosting | Isolated virtual resources, more configuration control | Growing sites and custom apps |
| Dedicated hosting | One physical server, high control | Specialized or demanding workloads |
| Cloud hosting | Resources can scale across infrastructure | Variable traffic and resilient applications |
| Managed application hosting | Provider handles much of the platform maintenance | Teams focused on shipping software |
Benefits of Web Hosting
Hosting supports a live service, not just file storage.
- Provides public access to a website or web app around the clock.
- Supplies infrastructure for compute, databases, media, and network traffic.
- Can include monitoring, backups, security controls, and scaling.
- Lets teams deploy updates without operating physical servers.
Practical Limits and Responsibilities
Hosting reduces infrastructure work but does not remove application ownership.
- Shared plans can slow down when neighboring workloads use resources.
- Provider outages or incorrect DNS and server settings can make a site unreachable.
- Usage, renewal, storage, and bandwidth limits can affect long-term cost.
- Teams must protect secrets, manage access, apply updates, and test backup restoration.
How to Choose Web Hosting for a Website or Web App
Choose hosting based on the software's needs, not a headline feature list.
- Match the plan to static pages, database-driven apps, background jobs, or API traffic.
- Check deployment workflows, logs, monitoring, backup recovery, and support.
- Select regions close to users when latency matters.
- Review renewal terms and resource limits, not only introductory offers.
- Use free hosting for a static prototype when suitable, but confirm limits before production.
Web Hosting and Emergent
Hosting is the delivery layer after software is built and tested: an application must be deployed to a reachable environment before users can use it. An AI web app builder can help turn an idea into a full-stack application, while this guide explains how to build a website with AI. Launch hosted web apps with Emergent.
