A short history
.cloud was one of the new generic top-level domains introduced in the 2010s, during the wide expansion that opened the naming system to words of every kind. The word itself describes the way computing has moved from local machines to remote data centres and online services. Technology projects adopted the zone early, and it has since become a familiar ending for cloud products and their documentation.
Who runs it
Generic zones such as .cloud are overseen by ICANN, the body that coordinates the global domain system. Each zone has a registry operator that holds a contract for it and maintains the database and the name servers. Customers buy names from registrars, who pass the orders on and handle renewals and changes.
Rules in practice
- Open zone: registration is generally open to individuals and companies, but the registry's own terms apply.
- Length: a name can reach 63 characters and uses only letters, digits and hyphens.
- DNS: you can point the name to any hosting platform, or use your own name servers.
- Renewal: keep the expiry date under review, especially for names that serve live applications.
Who uses .cloud
- Software-as-a-service products and online tools for businesses.
- Managed hosting, backup and storage providers.
- Developer documentation, status pages and API portals.
- Consultancies that help companies move their systems to remote infrastructure.
Strengths
- The ending explains the field of work immediately, which helps a technical product stand out in a crowded market.
- The word is short and modern, and it works well as part of a brand name.
- Because the zone is not tied to any country, it suits companies that operate across several markets.
Things to keep in mind
- The word cloud is used in many contexts, so a non-technical audience may not link it to a specific service.
- Strong names built from common words are often claimed early, so a short and distinctive name may be easier to find.
- The extension does not make a service more reliable, because uptime depends on the infrastructure behind the name.
- Trademark owners in the technology field may object to names that sit close to their products.
Tips before you register
- Use the same name in your product, documentation and social profiles.
- Set up a status page on a subdomain so that users can check service health.
- Protect the registrar account with two-factor authentication.
- Enable HTTPS on every page before you publish the first version.
- Turn on auto-renewal, because a lapsed name can break integrations that depend on it.
Frequently asked questions
Do I need a cloud product to register .cloud? No. Anyone can usually register the extension, although it fits technology projects most naturally.
Does the ending affect hosting quality? No. Speed and reliability depend on the infrastructure behind the name, not on the extension.
Can I use .cloud for a private company portal? Yes. A domain can host a restricted area with a login just as well as a public site.
