VPS and VPN are two concepts that are often easily confused because they are both quite similar acronyms. However, these are two completely separate concepts and are used for different purposes. VinaHost will help you distinguish the differences between these two services through this article. Let’s find out!

1. Overview of Virtual Private Server(VPS)

1.1. What is a VPS?

VPS stands for “Virtual Private Server”. This is a form of web hosting where a physical server is divided into multiple independent virtual servers, each of which runs the same operating system and software as a separate server.

Each virtual server has its own resources, including memory, CPU, storage and bandwidth, helping to ensure that users are not affected by other servers on the same system. Administrators have root (or admin) access and complete control over their virtual server.

VPS is often used to deploy and manage web applications, websites, databases and many other purposes, being an intermediate choice between shared hosting services and private servers.

1.2. How does a VPS work?

Virtual private servers (VPS) use virtualization technology to divide a physical server into multiple virtual servers. Each virtual server operates independently, just like a dedicated physical server. Here’s how VPS works:

Physical server: This is a powerful server with many resources such as CPU, RAM, storage capacity and network bandwidth.
Hypervisor: Is a software called hypervisor or Virtual Machine Monitor (VMM), running on a physical server. Hypervisor creates and manages virtual servers, ensuring they operate independently of each other. Popular hypervisors are VMware, KVM, Hyper-V, and Xen.
Virtual Server (VPS): Each VPS is a separate virtual environment created by the hypervisor. It has its own share of resources from the physical server (CPU, RAM, disk space, etc.). Even though they share physical hardware, these virtual servers are still completely separate and do not affect each other.
Operating system: Each VPS runs its own operating system, which may be different from the host operating system or other VPSs on the same physical server. This allows users to have root access and configure the server as desired, install software and host websites or applications.
Resource Allocation: Hypervisor allocates specific amounts of CPU, RAM, storage, and network bandwidth to each VPS. This allocation ensures each VPS has its fair share of resources and can be adjusted as needed.
Management and control: Users can manage their VPS via control panel or command line interface. They can start, stop, restart, and configure their VPS as they would manage a physical server.

1.3. Types of VPS Hosting?

VPS hosting can be classified based on factors such as management level, virtualization technology, and specific use cases. Here are the main types of VPS hosting:

Linux VPS Hosting

Features: Runs on the Linux operating system, famous for its flexibility, security and reasonable cost. Supports many distributions such as Ubuntu, CentOS, Debian and Fedora.

1.4. Pros of VPS Hosting

Virtual servers bring many advantages to users, including:

High performance: Each virtual server has separate resources such as CPU, RAM, SSD to help increase performance compared to shared hosting services.
Maximum control: Users have root (or administrator) access on the virtual server, which provides complete control over the operating system and configuration.
Flexibility: VPS allows users to customize the system configuration to their specific needs and install their own applications and software.
Secure and private: Since each virtual server operates independently of the others, it provides a more secure and private environment than shared hosting.
Scalability: Users can easily expand resources such as CPU, RAM, and storage as needed without affecting other servers.
Cost savings: VPS is a more cost-effective option than traditional physical servers. This is because users only need to pay for the resources they use.
Good support: Many virtual server providers provide professional and fast technical support, helping users solve problems effectively.

1.5. Cons of VPS Hosting

VPS service is not perfect in all aspects. In fact, you should only consider using a virtual server when you want to upgrade from shared hosting. At that time, you will have more space and flexibility to manage (websites, for example). Below are some disadvantages when using VPS.

Cost: Compared to shared hosting services, virtual servers can be more expensive and require more technical knowledge, which can increase cost and difficulty for beginners.
Management and maintenance: Due to the high level of control, virtual server management requires extensive technical knowledge. Users need to know how to manage the operating system, install and update software, and handle security issues.
Storage capacity: Although resources can be expanded, VPS storage capacity is often limited compared to physical servers. This can become a limitation for large projects with massive storage needs.
Shared performance: Although each VPS has its own resources, it still shares physical resources with other virtual servers on the same server. If one VPS overuses resources, it can affect the performance of other VPSes.
Depends on the provider: VPS performance and service quality depends heavily on the provider. If the provider has infrastructure or technical support problems, users may encounter difficulties.
High technical requirements: To take full advantage of virtual servers, users need to have enough technical knowledge to manage and optimize their system. This can be challenging for beginners.

2. Overview of Virtual Private Network(VPN)

2.1. What is a VPN?

VPN stands for “Virtual Private Network”. This is a technology designed to create a secure and private connection on the internet, allowing users to securely access and send data over a public network such as the internet.

When connecting via a virtual private network, data is encrypted, helping to protect personal information and prevent outside tracking. VPN creates a secure “tunnel” between the user’s device and the VPN server, through which information can be transmitted safely without worrying about the risk of loss or outside interference.

Common applications of virtual private networks include protecting internet privacy, avoiding surveillance, and allowing access to information sources or services that may otherwise be geographically restricted.

2.2. How does a VPN work?

A virtual private network (VPN) creates a secure and encrypted connection between your device and a remote server. This helps hide your IP address and encrypt your internet traffic, ensuring privacy and security. Here’s a simple explanation of how a VPN works:

VPN Software: You install the VPN software on your device (computer, phone, tablet). This software establishes and manages VPN connections.
Connect to a VPN Server: When you open the software and connect to a VPN, the software connects to a VPN server, usually in a different location.
Data Encryption: VPN software encrypts your internet traffic before it leaves the device. This encryption turns data into an unreadable form, helping to protect your information.
Create a Secure Tunnel: Encrypted data is sent through a secure tunnel to the VPN server. This tunnel uses protocols such as OpenVPN, L2TP/IPsec or WireGuard to ensure a secure connection.
VPN Server: When the data reaches the VPN server, it will be decrypted. The VPN server then forwards your traffic to the website or service you want to access using the VPN server’s IP address.
Hide Your IP Address: Because traffic is forwarded through the VPN server, the website or service you visit only sees the VPN server’s IP address, not the actual IP address your. This hides your real location and identity.
Data Return: When a website or service sends data back (like a web page or file), the data goes to the VPN server first. The VPN server encrypts the data and sends it back through a secure tunnel to your device, where the VPN software decrypts it so you can view or use it.

2.3. Types of VPN?

There are different types of VPNs designed to serve different purposes and use cases:

Remote Access VPN (Remote Access VPN)

Allows individual users to remotely connect to a private network and access the network’s internal resources. Commonly used for remote employees to securely connect to the company’s internal network.

Site-to-Site VPN (Or Router-to-Router VPN)

Connect the entire network of offices or branches together securely via the internet. Used by businesses to connect offices and branches safely and effectively.

VPN Client-to-Site

Allows personal devices to remotely connect to a specific server on the network. Typically used when a user wants to remotely connect to a specific server instead of accessing the entire network.

VPN L2TP (Layer 2 Tunneling Protocol)

Uses layer 2 tunneling protocol to create a secure connection between client and server. Often combined with IPsec to provide security for data transmitted through the tunnel.

VPN IPsec (Internet Protocol Security)

Use the IPsec protocol suite to secure information transmitted over the Internet Protocol (IP). Often widely used to protect remote and site-to-site connections.

SSL VPN (Secure Socket Layer VPN)

Use SSL or TLS protocol to create a secure and encrypted connection between client and server. Typically used for remote access via a web browser without the need for special client software.

VPN PPTP (Point-to-Point Tunneling Protocol)

Uses a point-to-point tunneling protocol to create a secure connection. However, due to security holes, it is no longer recommended for use in modern solutions.

OpenVPN

Is an open source VPN protocol that uses custom security protocols based on SSL/TLS for key exchange. Famous for its security, reliability and high configurability.

WireGuard

Modern VPN protocol, designed for simplicity and improved performance compared to other traditional protocols like OpenVPN.

Mobile VPN

Optimized for mobile devices, helping to maintain a continuous and secure connection when the mobile device switches networks or changes IP addresses.

Each type of VPN has unique characteristics and is suitable for different usage needs.

2.4. Pros of VPN

The outstanding advantage of a virtual private network is that it meets the high security needs of users. In addition, virtual private networks have many other advantages such as:

Data security: Virtual private networks encrypt data between your computer or device and the server, making it difficult for attackers to read or understand information transmitted over the network.
Protects privacy: VPNs help keep your online activity protected and hidden from those who want to track you, including your ISP (Internet Service Provider).
Access most content, such as geo-restricted content: You can access websites and online services that may be geo-restricted, because a VPN allows you to connect from another virtual location.
Stay safe when using public Wi-Fi: When using public Wi-Fi, a virtual private network helps protect personal information from being stolen.
Avoid geo-targeted advertising: Virtual private networks help you “switch geolocation” and view online content from other areas, which can avoid geo-targeted advertising.
Secure remote work: Enables remote workers to securely connect to the corporate network and access internal resources without worrying about security.
Avoid surveillance tools: Virtual private networks help prevent online surveillance and tracking tools, protecting user privacy.

2.5. Cons of VPN

Using a virtual private network is an ideal choice for users accessing the Internet. However, virtual private networks also have some limitations.

Slow in use: Data encryption and decryption can cause connection speeds to decrease, especially when using free VPN services.
Limited by capacity and speed: Free VPN services often limit capacity and speed, which can affect the usage experience.
Sometimes not safe: Some untrusted virtual private network services may store and share your personal information, posing information security risks.
Likely to be blocked: Some organizations and websites may detect and block users from using VPNs to access content.
Dependence on third-party services: Dependence on a virtual private network service can increase risk, especially if that service crashes or stops working.
IP address spoofing: VPNs can be used to spoof IP addresses, which could lead to abusive use or legal liability.
Must pay if you want to use advanced services: If you want to use a quality and full-featured virtual private network service, you may need to pay a fee, which increases the cost of using a virtual private network.

2.6. When to Choose a VPN

You should be able to apply a virtual private network in the following cases

When using public Wi-Fi: Public Wi-Fi is often not secure and your data can be stolen. A VPN will help protect your data from being stolen or eavesdropped.
When working remotely: A VPN will allow you to securely access your company’s intranet remotely.
When using highly secure online applications or services: A VPN will help protect your data when you are using highly secure online applications or services, such as online banking online or pay online.
When you want to protect your privacy: A VPN will help hide your IP address, helping you browse the web anonymously.
Access geo-restricted content: If you want to access geo-restricted online content or services (e.g. international TV content), a VPN can help you bypass restrictions.
When you want to avoid blocking or censorship: If you are in a country or network where access to certain websites or services is blocked, a VPN can help you avoid this censorship.
When you need to ensure safe content downloads: When downloading content from the internet, a virtual private network can help protect your computer from cyber threats and increase safety.
