A domain and a VPS are the two foundations that let a website operate on the internet. The domain gives customers a memorable address; the VPS provides the resources to store the source code and database and to process requests.
Choosing correctly from the start keeps the website stable, easy to expand, and saves you from migrating providers later. Below is a process for beginners, from picking a domain name to receiving your server details.
What is a domain?
A domain is the address a user types into a browser to reach a website. The DNS system translates that name into the server's IP address. A good domain should be short, easy to read, easy to type and directly connected to the brand.
- Prefer the brand name or your main identifying keyword.
- Avoid hyphens, hard-to-remember numbers and easily confused characters.
- Check the domain's history and trademark status before buying.
- Enable auto-renewal and two-factor authentication on the domain management account.
The domain purchase process
- 01
Find an available name
Enter the name you want in the registrar's search tool. Compare .com, .vn or whichever extension suits your target market.
- 02
Register the owner details
Enter your name, email, phone number and legal details accurately. This data is used to verify ownership of the domain.
- 03
Pay and secure the account
Complete the payment, verify the email, enable 2FA and note the renewal details. Never share domain admin credentials in a public chat.
What is a VPS and when should you use one?
A VPS is a virtual server with its own CPU, RAM, storage and operating system. Compared with shared hosting, a VPS gives you far more control over the application environment and lets you install the services you need.
A VPS suits websites that run background tasks, cron jobs, queues or APIs, or whose traffic is growing. In exchange, you have to care about OS updates, the firewall, backups and resource monitoring.
How to choose a VPS configuration
- CPU: start from 2 vCPU for a database-backed website and upgrade as the load grows.
- RAM: 2–4 GB suits most new websites; you need more when running several services at once.
- Disk: prefer SSD/NVMe and pick a size with headroom for logs, backups and images.
- Server location: choose one close to your main audience to reduce latency.
- Backups: prefer a provider with snapshots or automated backups, but still keep one copy outside the VPS.
Note: Start with a plan that is just enough and choose a provider that allows flexible upgrades. Do not pick a configuration on lowest price alone.
Buying and receiving a VPS
- 01
Create a provider account
Use an email you check regularly, enable 2FA and store the recovery codes somewhere safe.
- 02
Choose the plan and operating system
Pick a configuration that matches your needs, a suitable data centre and an OS supported by whoever deploys the website.
- 03
Receive the server details
After payment, the provider sends the IP, the account and connection instructions. Change the initial password before putting it into use.
- 04
Point the domain at the VPS
Create the DNS records as instructed, install SSL and wait for DNS to propagate before testing the site on the real domain.
A checklist before going live
- Change admin passwords and disable logins you do not need.
- Configure HTTPS, the firewall and operating system updates.
- Set up automated backups and test that you can restore them.
- Monitor CPU, RAM, disk space and uptime.
- Keep invoices and the renewal dates of the domain and VPS in one place.
