VPS Hosting: A Complete A-Z Guide for Beginners

Are you running your website on shared hosting but experiencing slow performance or being affected by “neighbors” on the same server? Or do you need a dedicated environment to run applications, install Docker, or set up a game server? Renting a VPS is the next logical step, but if you have never used one before, you probably have many questions.

This article will help you understand what VPS hosting is, when to rent one, which type to choose, and how to deploy it from start to finish.

What is VPS Hosting?

What is VPS? Simply put, VPS (Virtual Private Server) is a virtual server separated from a physical server. Each VPS has its own CPU, RAM, storage, and operating system, operating independently like a real server.

VPS hosting means you pay monthly (or yearly) to use a VPS from a provider, instead of buying and operating a physical server yourself.

Why not use shared hosting? Shared hosting shares resources among hundreds of websites. When another site on the same server is overloaded, your site is also affected, although currently high-end shared hosting services like Pro Platinum Hosting or Premium Business Hosting always minimize this situation. However, the biggest reason to use VPS is flexibility and support for specific needs, such as running OpenClaw, Docker, Coolify, or websites with high traffic…. If you are looking for cheap hosting for a small blog, shared hosting is still fine, but when traffic increases or you need custom installations, VPS is a better choice.

Why not rent a dedicated server? A dedicated server gives you the entire physical hardware, but prices range from several million to tens of millions per month, and if errors occur, reinstalling or troubleshooting takes more time and effort. Therefore, using VPS is the most balanced solution between cost, performance, and convenience.

Who Should Rent a VPS?

VPS is suitable for many users, not just technical people:

• Developers, freelancers: need dev/test environments, CI/CD, deploy Node.js, Python, Go applications
• Small businesses: company websites need stability, don’t want to be affected by other sites on shared hosting
• E-commerce: run WooCommerce, OpenCart or e-commerce platforms that need fast processing speed and stable resources
• Self-hosting apps: set up Nextcloud, n8n, Gitea, Mattermost, or any application that needs a dedicated server
• Game servers: host Minecraft, Mu Online, Ragnarok or private game servers

If you only run a small WordPress blog with a few hundred visits per day, hosting is still the most suitable choice. VPS becomes meaningful when you need more control or more resources.

Common Types of VPS

Classification by Virtualization Technology

KVM (Kernel-based Virtual Machine): most popular currently. Each VPS runs its own kernel, supports full operating systems (Linux, Windows). Resources are allocated real, not oversold. Most reputable providers use KVM.

OpenVZ: older technology, shares kernel between VPS instances. Advantages are lightweight, fast startup. Disadvantages are cannot install kernel modules, cannot run Docker (on old versions), and easily oversold resources. Currently few providers still use OpenVZ for new packages.

Cloud VPS (or called Cloud Server): VPS running on cloud infrastructure, data is usually replicated in multiple copies. When a physical node fails, VPS automatically switches to another node (failover). Suitable for workloads that need high uptime.

Managed vs Unmanaged

Some providers may mention this or not, but most current VPS services, especially cheap VPS, are Unmanaged VPS.

Unmanaged VPS: you manage everything yourself, from installing OS, configuring web server, security to backup. Cheaper, but requires basic Linux knowledge.

Managed VPS: provider handles the system part, security updates, installs control panel (cPanel, DirectAdmin). You only need to manage the website. Higher price but saves time, suitable for non-server specialists.

Criteria for Choosing a Reputable VPS Provider

There is no shortage of VPS providers in the market. The issue is choosing the right one. Below are important criteria:

Uptime commitment: minimum 99.9%. Ask clearly about SLA (Service Level Agreement) and compensation policy when downtime occurs.

Technical support: 24/7 support via livechat or tickets is the minimum standard. More important is response time and quality of handling. Some providers respond quickly but only give general answers without solving problems.

Data center: server location directly affects speed. If customers are mainly in Vietnam, choose VPS with data center in Vietnam or Southeast Asia region.

NVMe storage: prioritize VPS services that announce using NVMe storage because of very high speed, 3-5 times faster than SSD. You can still choose SSD if larger capacity is needed. Usually VPS when running will not exceed 200MB/s unless there are file processing tasks (compression, extraction,…) so don’t focus too much on this issue.

Backup: VPS services usually do not include backup, or charge extra for this feature. Therefore, if the provider has free backup integrated with VPS, it’s a plus point.

Pricing: VPS in Vietnam currently ranges from about 79,000 VND to several million VND per month depending on configuration. Don’t choose the cheapest package if RAM is only 512MB, because the operating system already takes up almost all. 1-2GB RAM package is a reasonable starting point for most use cases.

Vietnam VPS vs Foreign VPS

This is a common question. The answer depends on target customers and purpose of use.

Choose Vietnam VPS when:

• Customers are mainly in Vietnam (business websites, domestic e-commerce, Vietnamese blogs)
• Need fast domestic access speed (ping under 10ms)
• Need Vietnamese technical support, fast handling according to Vietnam time
• Data storage according to Vietnamese law regulations

Choose foreign VPS when:

• Customers are mainly abroad or global
• Need foreign IP (running tools, international SEO, VPN)
• Need data center at specific location (Singapore, US, EU)

Quick Comparison: Shared Hosting vs VPS vs Cloud Server vs Dedicated

Criteria	Shared Hosting	VPS	Cloud Server	Dedicated Server
Resources	Shared	Private (virtualized)	Private + HA	Private (physical)
Root access	No	Yes	Yes	Yes
Scalability	Limited	Upgrade package	Flexible, fast	Replace hardware
Uptime	Depends on server	99.9%+	99.99%+ (failover)	99.9%+
Price/month	29K – 200K	79K – 2 million+	99K – 3 million+	3 million – 30 million+
Management	No technical needed	Basic knowledge needed	Basic knowledge needed	Expert needed
Suitable for	Small blogs, landing pages	Medium websites, apps, dev	Enterprise, e-commerce	Large enterprise, gaming

For most users, VPS is the first jump from shared hosting. Cloud Server is suitable when you need higher uptime and auto-recovery capability when hardware failures occur.

VPS Hosting Process from A to Z

Step 1: Determine Your Needs

Before choosing a package, answer a few questions:

• What will you run on the VPS? (website, app, database, game server?)
• Expected traffic or concurrent users?
• What operating system needed? (Ubuntu, CentOS, AlmaLinux, Windows?)
• Need control panel? (cPanel, DirectAdmin, CyberPanel?)

Step 2: Choose Suitable Package

Some suggestions by use case:

• WordPress blog, small site: VPS with 1 vCPU, 1GB RAM is enough to start
• WooCommerce, e-commerce: from 2 vCPU, 2-4GB RAM and up
• Docker, multiple containers: 4GB RAM and up, prioritize NVMe
• Game server: need VPS with GPU or high RAM configuration

For example at AZDIGI, cheap VPS X-Platinum VPS packages start from 79,000 VND/month with 1 vCPU, 512MB RAM, 10GB NVMe. Pro VPS packages from 99,000 VND/month with 1 vCPU, 1GB RAM, 10GB SSD, suitable to start.

Step 3: Register and Payment

Registration process at most providers is quite similar:

1. Choose VPS package, choose payment cycle (monthly/quarterly/yearly)
2. Choose operating system (Ubuntu 22.04 or 24.04 are popular choices)
3. Choose data center location
4. Payment (bank transfer, e-wallet, international card)

After payment, you receive an email containing IP information, root account and password. Activation time is usually 1 to 5 minutes.

Step 4: Initial Configuration

SSH into the VPS and perform basic steps:

# SSH connection
ssh root@your-server-ip
# Update system
apt update && apt upgrade -y
# Create new user, don't use root directly
adduser myuser
usermod -aG sudo myuser

Step 5: Deploy Application

Depending on purpose, you can:

• Install LAMP/LEMP stack for websites
• Install Docker to run containers
• Install control panel (CyberPanel, HestiaCP free; cPanel, DirectAdmin licensed)
• Deploy applications via Git, Docker Compose, or automated scripts

Important Notes When Renting VPS for the First Time

Many people buy VPS and leave it with default settings. This is a way to “open the door” for hackers. Below are things to do immediately:

Backup immediately from start: don’t wait until you lose data to think about backup. Set up automatic backup (snapshot, rsync, or use provider backup). Keep at least 1 offsite backup (different server).

SSH security:

• Change default SSH port (22) to another port
• Disable password login, use SSH keys
• Disable root login via SSH

# In /etc/ssh/sshd_config
Port 2222
PermitRootLogin no
PasswordAuthentication no

Firewall: enable firewall, only open necessary ports. UFW on Ubuntu is the simplest choice.

ufw allow 2222/tcp   # New SSH port
ufw allow 80/tcp     # HTTP
ufw allow 443/tcp    # HTTPS
ufw enable

Monitoring: monitor resources (CPU, RAM, disk) to know when to upgrade. You can use htop, Netdata, or UptimeRobot to receive notifications when server is down.

Regular updates: run apt update && apt upgrade regularly. Enable unattended-upgrades for automatic security patches.

FAQ

How much does VPS hosting cost?

VPS in Vietnam costs from about 79,000 VND/month for basic package (1 vCPU, 512MB RAM). Most popular packages for websites usually range from 139,000 VND to 390,000 VND/month with 1-2 vCPU and 1-4GB RAM. Price increases based on configuration, CPU type (Intel Platinum, AMD EPYC) and storage type (SSD, NVMe).

Do I need to know Linux to rent VPS?

If you rent unmanaged VPS, then yes. You need to know SSH, software installation, web server configuration, basic troubleshooting. However, if you use control panels (cPanel, CyberPanel, HestiaCP), operations are through web interface, don’t need many commands. Some providers have managed VPS where technical teams help with installation and management.

Is Vietnam VPS or foreign VPS better?

There is no absolute answer. If customers are in Vietnam, Vietnam VPS gives faster access speed (low ping, domestic routing). If customers are abroad or you need international IP, foreign VPS (Singapore, US) is more suitable. For more details, read the article Vietnam or foreign VPS.

Should I rent VPS monthly or yearly?

Monthly rental is more flexible, easier to change packages or switch providers. Yearly rental usually gets 10-20% discount, suitable when you are sure about the provider and configuration package. Suggestion: start monthly, run stable for 2-3 months then switch to yearly payment to save.
