Colocation

Colocation (also known as Server Colocation) is a service that allows a business or individual to rent space (by the U or as a full Rack) in a professional data center facility to place their own Servers or network equipment.

Instead of investing in and operating a costly private server room, you get to leverage the Data Center's superior infrastructure, including power, cooling, high-speed internet connectivity, and physical security. In this model, the client retains full ownership and management of their equipment, while the service provider ensures the infrastructure operates with constant stability and security.

Technical Working Principle

The Server Colocation service operates on a clear model of shared responsibilities:

• Client Owns the Hardware: You have full ownership, choice of configuration, and responsibility for your server hardware, as well as the software and data within it.
• Provider Operates the Infrastructure: The service provider is responsible for ensuring the entire physical infrastructure of the Data Center (power, cooling, network, security) operates 24/7.
• Leveraging Shared Strength: You benefit from high-end infrastructure at a reasonable cost because the Data Center's operational expenses are shared among many clients.

Key Benefits of Server Colocation

Choosing a Colocation service offers numerous strategic advantages for your business:

• Investment & Operational Cost Savings: Completely eliminate the costs of building and maintaining a server room, including expenses for electricity, cooling, and infrastructure staff.
• Professional Datacenter Infrastructure: Your server is housed in a standard-compliant environment with N+1 backup power, standardized cooling and temperature systems, and automatic fire suppression.
• High-Speed & Stable Connectivity: Enjoy high-bandwidth, low-latency internet connectivity with redundancy from multiple different Internet Service Providers (ISPs).
• Strict Physical Security: Ensure the absolute safety of your physical assets with 24/7 security, surveillance cameras, and biometric access control.

Applications and Use Cases

Server Colocation is the ideal solution for a variety of needs and scales:

• Clients with Existing Physical Servers: Individuals or companies that have already purchased their own servers and need a professional environment to operate them instead of at home or in the office.
• Systems Requiring Specialized Hardware: Projects that demand specific server configurations, GPU cards, or network equipment not available in standard dedicated server rental services.
• Disaster Recovery (DR) & Backup: Establishing a secondary site to back up data and be ready to operate if the primary system fails.
• Web Hosting & Gaming Companies: Service providers who need a powerful, stable, and scalable infrastructure to serve their own customers.

1. What is Bandwidth?

Bandwidth is the maximum data transfer capacity of a network connection over a specific period, typically measured in Mbps (Megabits per second) or Gbps (Gigabits per second).

To make it easier to understand, you can think of bandwidth like the width of a highway. The wider the road, the more cars can travel at the same time. Similarly, the larger the bandwidth, the more data (images, videos, text) can be transferred between your website and your users per second.

2. Understanding Megabits (Mbps) vs. Megabytes (MB/s)

This is the most common point of confusion. Network service providers (including VietHosting) typically advertise bandwidth speed in Megabits per second (Mbps), but the file download speed in your browser is shown in Megabytes per second (MB/s).

The conversion rule is simple: 1 Megabyte = 8 Megabits.

• To calculate the theoretical maximum download speed (in MB/s), you simply divide the advertised speed (in Mbps) by 8.
• Example: A hosting plan with 100 Mbps bandwidth will have a theoretical maximum download speed of 100 / 8 = 12.5 MB/s. The actual speed might be slightly lower due to transmission overhead, which is why you might see speeds around 10-12 MB/s.

3. Domestic Bandwidth

This is the data transfer rate for network connections within Vietnam's territory. This bandwidth is optimized for high speed and extremely low latency, making it ideal for websites and applications primarily serving users in Vietnam.

4. International Bandwidth

This is the data transfer rate for connections from Vietnam to other countries and vice versa. Due to long geographical distances, international bandwidth typically has higher latency and lower committed speeds compared to domestic bandwidth.

5. Shared Bandwidth Policy at VietHosting

To provide services at a reasonable cost, we operate on a shared bandwidth model. This means the advertised network speed is the maximum port speed your service is connected to. If your project requires guaranteed network speeds or needs dedicated bandwidth, please contact us for a consultation on a suitable solution.

Yes, basic support for OS installation and server optimization is available for VietHosting's Colocation customers.

Additionally, we offer dedicated Server Management services for ongoing administration needs.

VietHosting operates on a shared bandwidth model for its services. Therefore, the advertised network speeds (e.g., Domestic Bandwidth 1 Gbps, International Bandwidth 32 Mbps) represent the maximum allowed speed that VietHosting's system sets and limits for your service on our shared network infrastructure. This is not the same as dedicated bandwidth reserved solely for each customer.

Because this bandwidth resource is shared among multiple users and the maximum speed is limited by the system, VietHosting does not guarantee that you will consistently achieve this maximum allowed speed. Actual speeds will depend on the overall network traffic at the time of use and our bandwidth management policies.

If you require stable network speeds or guaranteed dedicated bandwidth for your service, please contact VietHosting directly. We will provide detailed consultation and pricing for suitable dedicated bandwidth solutions.

As per the Refund Policy, Colocation and Dedicated Server services are not eligible for refunds.

Why is this the policy?

The Colocation service, by its nature, involves VietHosting reserving dedicated physical space, power, and committed network ports for you in the Data Center. This requires long-term investment and infrastructure resource planning on our part. Because these resources are reserved exclusively for you for the entire billing cycle, they cannot be re-allocated to another customer, and therefore, we cannot issue a refund for the unused time.

How do I stop the service renewal?

Although a refund is not possible, you have the full right to cancel the service renewal for the next cycle. To avoid unwanted charges, you must submit a cancellation request with the 'End of Billing Cycle' option through the client area at least 7 days before the service's expiration date.

For More Information

For more details, please refer to our full Refund Policy (Section 4).

CloudLinux OS is a commercial Linux-based operating system designed specifically for shared hosting environments. Its core technology is LVE (Lightweight Virtual Environment), which creates isolated virtual "containers" to partition and limit resources (like CPU, RAM, and I/O) for each account, significantly enhancing the stability and security of the entire server.

By isolating each account, CloudLinux OS has revolutionized the shared hosting industry, transforming a traditionally unstable environment into one that is as secure and reliable as a virtual private server (VPS), while providing maximum flexibility for end-users.

Technical Working Principle

CloudLinux OS operates on three core technologies working in concert:

• LVE (Lightweight Virtual Environment): The "heart" of CloudLinux, this technology creates separate containers to limit resources (CPU, RAM, I/O, Processes) for each account. If one account experiences a surge in usage, it will be throttled rather than crashing the entire server.
• CageFS (Virtualized File System): This creates a virtualized file system ("cage") for each user, completely isolating their data and preventing them from seeing sensitive information or the files of other users on the same server.
• PHP Selector: This allows each hosting account to freely choose its required PHP version (from legacy 5.x to the latest 8.x) and necessary extensions without affecting the server's global configuration.

Key Benefits of CloudLinux OS

Implementing CloudLinux OS on a server provides strategic benefits for both providers and end-users:

• Enhanced Stability & "Noisy Neighbor" Prevention: LVE completely solves the issue of one website using too many resources and impacting others. Each account is guaranteed its share of resources, ensuring consistent website performance.
• Superior Security & Absolute Isolation: CageFS effectively prevents privilege escalation and local attacks, two of the most common forms of attacks in shared hosting environments.
• Flexible PHP Version Selection: Users have full control to choose the most suitable PHP version for their website's source code, ensuring compatibility and allowing the use of the latest technologies.
• Optimized Performance & Server Density: Allows hosting providers to serve more customers on a single server safely and reliably, which in turn helps reduce the cost of the service.

Applications and Use Cases

CloudLinux OS is an essential solution for multi-user server environments, especially:

• Shared Hosting Providers: This is the primary audience. CloudLinux helps increase customer density per server, reduce support tickets, and improve service quality.
• Developers & Hosting Resellers: It provides a flexible and secure environment for their clients, allowing for easy customization of the PHP environment.
• Schools & Educational Organizations: Creates secure and isolated hosting environments for students or different departments on the same infrastructure.
• Any Server with Multiple Websites: Any server hosting multiple websites from different users should use CloudLinux to ensure stability and security.
