What is VPS hosting?

VPS in one paragraph

A virtual private server is a slice of a powerful physical server that behaves like a separate computer. Special software called a hypervisor divides the physical machine's processors, memory and storage into several virtual machines. Each one runs its own operating system, has its own IP address and gets a fixed allocation of resources. You can install what you like, restart it on your own, and other customers on the same physical server cannot see your files or use your share of RAM.

That sits between shared hosting, where many customers use one server's software together with fixed limits, and a dedicated server, where you rent a whole physical machine.

How virtualisation works

Virtualisation is a mature technology used in almost every data centre. In simple terms:

1. The physical host is a server with many CPU cores, a large amount of RAM and fast storage.
2. The hypervisor runs on the host. Common examples are KVM on Linux and Microsoft Hyper-V on Windows Server.
3. Virtual machines are created on top. Each is given a number of virtual CPU cores (vCores), an amount of RAM and a virtual disk.
4. Each VPS boots its own operating system, such as a Linux distribution or Windows Server, as if it were a real computer.

The hypervisor keeps virtual machines isolated from each other. A crash or a security problem in one VPS should not affect the others, and a neighbour's busy website cannot take your allocated memory.

One caveat: virtual machines on the same host still share the physical hardware underneath. If a host is heavily loaded, CPU and disk performance can vary. That is why a VPS sits between shared hosting and a dedicated server on isolation as well as price.

What you control on a VPS

On shared hosting the provider decides the software. On a VPS you decide. Typically you can:

• Choose and configure the software stack: web server (Nginx, Apache, IIS), language runtimes (PHP, Python, Node.js, .NET), databases and caches.
• Run background services, such as queue workers, scheduled jobs and websockets.
• Open custom ports and run non web services such as an API or an internal tool.
• Install system packages your application needs.
• Restart the server or individual services when you choose.

How much of this you can do depends on the level of access the provider gives you. On most VPS products sold without a management service, you get full administrative access: root on Linux or the Administrator account on Windows. Some providers offer a managed option where they handle updates and security for you. Always confirm which applies before you order.

ODHOST note: The ODHOST VPS plan pages list a control panel but do not name it, and do not state access level, operating system choices or whether the VPS is managed. Confirm these with ODHOST by ticket before ordering if your project depends on them.

What you are responsible for

Control comes with duties. On a typical VPS you or your developer are responsible for:

• Operating system updates and security patches.
• Firewall rules and closing services you do not use.
• Strong authentication, for example SSH keys instead of passwords on Linux.
• Backups of your files and databases, unless your plan includes a backup service.
• Monitoring disk space, memory and uptime.
• Software updates for the web server, PHP or .NET, and the database.

If nobody in your business can do this, budget for a developer or administrator, or stay on shared hosting where the provider handles the server. Our help article on connecting to a VPS with SSH shows the first step for Linux.

When you need a VPS

A VPS is the right move when at least one of these is true:

• Your application needs software shared hosting does not allow, such as Node.js or Python services, Docker, Redis or a specific database version.
• You need reserved resources. A shop running promotions, or an application with many logged in users, should not compete for CPU with hundreds of other sites.
• Your site regularly hits shared hosting resource limits, even after caching and optimisation.
• You need a dedicated IP address or custom server configuration.
• You are an agency hosting many client sites and want one environment you control.

You probably do not need a VPS for a brochure site, a blog or a small shop that runs well on shared hosting. The shared vs VPS comparison lists clear signals for when to switch.

Linux VPS vs Windows VPS

	Linux VPS	Windows VPS
Typical software	PHP, Python, Node.js, Ruby, Java, MySQL, PostgreSQL, Nginx, Apache, Docker	Classic ASP.NET (.NET Framework), IIS, Windows only desktop or server software
How you connect	SSH from a terminal	Remote Desktop (RDP), typically
Cost	Lower, as most distributions are free	Higher, as the price usually covers a Windows Server licence
Resource use	Light; a small VPS runs a web stack comfortably	Windows itself uses more RAM, so size up
Who uses it	Most web developers, startups, agencies	Businesses with Windows specific applications

ASP.NET Core runs on Linux as well, so a modern .NET application does not automatically need Windows. Choose Windows when your software genuinely requires it. The Linux vs Windows hosting comparison explains this in more detail.

ODHOST VPS plans

ODHOST's VPS plans run on servers located in India, use Intel Xeon processors, include one dedicated IPv4 address and list an uplink of up to 1 Gbps with unmetered bandwidth under fair use. Billing is monthly or yearly, with yearly at 12 times the monthly price. Applicable taxes are shown at checkout.

Plan	RAM	vCores	Storage	Monthly
Nano	2 GB	1	40 GB	₹699
Micro	4 GB	2	80 GB	₹1,349
Standard	8 GB	4	160 GB	₹2,699
Performance	16 GB	6	320 GB	₹4,999

Details and ordering are on the VPS hosting page. If your application needs a Windows server, contact ODHOST with your requirements before ordering.

VPS vs dedicated server

If a large VPS is still not enough, or you need a physical machine for isolation or compliance reasons, the next step is a dedicated server. Our guide on what a dedicated server is and the VPS vs dedicated comparison cover that decision.
