Introduction

As your website grows, so do its hosting needs. Most small businesses start their websites off on a shared web hosting plan. However, there will come a time when your website outgrows a shared hosting solution. If shared hosting no longer meets your site’s demands but dedicated hosting seems out of reach, it may be time to consider VPS hosting.

VPS or Virtual Private Server hosting, strikes a balance between cost and performance by providing users with dedicated resources within a shared environment. This unique setup gives your site the power and flexibility it needs to handle increased traffic, custom applications and enhanced security.

To help you find the best hosting solution for your website, this guide will walk you through everything you need to know about VPS hosting. Whether you’re a business owner, developer or blogger, understanding VPS hosting can be the key to unlocking your site’s potential. Let’s dive in and explore the world of Virtual Private Servers and what they can do for you! 

What is VPS hosting?

VPS Hosting (Virtual Private Server Hosting) is a web hosting solution designed to offer a middle ground between shared and dedicated hosting. Utilizing virtualization technology, VPS hosting partitions a single physical server into multiple isolated virtual servers, each of which operates independently.

In this setup, each virtual private server (VPS) has its own allocated resources, including CPU, RAM, storage and often its own operating system, allowing it to function like a mini-dedicated server. This structure gives users more control over their hosting environment compared to shared hosting, where resources are pooled among many users.

Unlike shared hosting, where all websites share the same resources on a single server, VPS hosting provides each user with dedicated resources, ensuring that one VPS user’s activities do not impact others. This dedicated environment is particularly beneficial for websites with moderate to high traffic or those that require custom configurations and additional control over their hosting environment without the full expense of a dedicated server.

Because of its flexible nature, VPS hosting is ideal for growing websites and applications that have outgrown shared hosting but aren’t yet ready for a dedicated server’s capacity or cost. The virtualization aspect of VPS hosting creates a balance between cost and performance, giving users more control and stability over their resources.

Key components of VPS hosting 

• Virtual private server (VPS): A virtual machine that mimics a dedicated server within a shared hosting environment. It is the backbone of VPS hosting, allowing a single physical server to operate as multiple independent virtual servers. 
• Virtualization technology: Software that creates and manages virtual servers on a physical server. 
• Dedicated resources: Each VPS has its own CPU, RAM, disk space and bandwidth, allowing better performance and control over server resources. 
• Operating system choice: Users can choose their preferred OS, often between popular options like Linux and Windows.
• Root access: Full administrative access to the server, allowing complete control over configurations and installations. VPS hosting often includes root access, enabling users to install custom software, modify configurations and have greater control over their environment. 
• Physical server: The actual hardware that hosts multiple VPS instances. 

How VPS hosting works

VPS hosting uses virtualization technology to split one server into multiple virtual servers. 

Hosting companies use a hypervisor (or a virtual machine monitor, VMM), specialized software that simulates and creates different virtual machines (VMs), also called guests. 

The hypervisor splits a host server into separate virtual parts on top of its operating system (OS). This enables the server to support other guests — allowing them to install their own software and their own OS. 

In a nutshell, virtualization works to give users sharing one server the illusion of private space. Thus, the name “virtual private server.” 

VPS works differently from shared hosting.

Every time a website overuses the shared server’s resources, it negatively affects another website’s performance. But that’s not the case with the VPS servers. 

With VPS hosting, your virtual server has allocated specific resources such as CPU, RAM, and storage. While these resources are shared with other virtual servers on the same physical machine, your allocation allows for more consistent performance compared to shared hosting. This isolation helps ensure that your website’s performance is less affected by other users on the same server. 

Common use cases for VPS hosting 

VPS hosting caters to a wide range of applications, making it a versatile choice for various website types. Some of the common applications include: 

• eCommerce sites: These sites need high security and consistent uptime, which VPS hosting can provide. VPS hosting provides the necessary resources and security features to handle online transactions and manage product inventories efficiently. 
• Hight traffic blogs and content Sites: As traffic increases, VPS can handle more visitors with reliable performance. 
• Web applications: Applications with custom software requirements can benefit from the flexibility of VPS hosting. 
• SaaS platforms: Software as a Service (SaaS) platforms benefit from VPS hosting’s scalability and reliability, ensuring seamless service delivery to users. 
• Business sites requiring secure data handling: VPS’s dedicated resources offer better protection for sensitive business information. 
• Development and testing environments: VPS hosting offers isolated environments for developers to test new features, perform experiments and develop applications without affecting the live website. 

VPS hosting compared to other types of hosting providers

VPS hosting stands out among several hosting options, each with its own set of advantages and limitations. Let’s compare VPS hosting to some other common types of hosting to help you make an informed decision: 

Shared hosting vs. VPS hosting:

Shared hosting: In shared hosting, multiple websites operate on the same server, sharing resources like CPU, RAM, storage and bandwidth. This makes shared hosting one of the most budget-friendly options. However, because resources are shared, your website’s performance can be impacted by other sites on the server, especially if they experience high traffic spikes. This setup works well for smaller sites and personal blogs but may not support high-demand websites that need consistent speed and performance. 

VPS hosting: VPS hosting provides a dedicated virtual environment within a larger physical server. This isolation ensures your site has its own allocated resources, meaning your site’s performance is less likely to be affected by others on the server. This setup is an ideal next step for websites that have outgrown shared hosting but don’t yet need a full dedicated server. It offers greater performance, control and reliability than shared hosting at a moderate cost.

Dedicated hosting vs. VPS hosting:

Dedicated hosting: Dedicated hosting provides a complete physical server dedicated exclusively to your website or applications. This setup allows for top-notch performance, full control over the server and the highest level of security. It’s especially useful for high-traffic websites or complex applications where stability and security are non-negotiable. However, this comes at a premium price and may be excessive for smaller sites or those with lower traffic levels. 

VPS hosting: VPS hosting serves as a middle-ground solution, offering dedicated resources within a shared physical server through virtualization. While not as powerful as a dedicated server, VPS hosting provides a level of control and performance that’s significantly greater than shared hosting. For websites that require solid performance but aren’t quite ready to commit to the cost of a dedicated server, VPS hosting offers a balance of cost-effectiveness and resource allocation. 

Managed WordPress hosting vs. VPS hosting 

Managed WordPress hosting: Managed WordPress hosting is specifically optimized for WordPress websites, offering features like automated backups, updates, security enhancements and a tailored WordPress support team. This option is great for users who want to focus on their content or business without handling server management tasks. Managed WordPress hosting tends to be more streamlined and user-friendly, with performance tweaks specifically for WordPress, but it may lack the customization that more advanced users seek. 

VPS hosting: VPS hosting provides a customizable virtual environment that allows full control over server settings and software installations, making it an excellent option for advanced users or those with custom configurations. While VPS hosting can support WordPress, it requires more manual setup and maintenance compared to managed WordPress hosting. For those who prefer flexibility and control and are comfortable managing their own server configurations, VPS hosting offers a powerful solution. 

Cloud hosting vs. VPS hosting:  

Cloud hosting: Cloud hosting operates across a network of virtual servers that pull resources from multiple physical servers. This structure provides exceptional flexibility and scalability, making it perfect for websites with varying or unpredictable traffic. If one server in the network experiences issues, your site can seamlessly switch to another, minimizing downtime. Cloud hosting’s distributed nature allows it to scale resources up or down as needed, accommodating growth and maintaining performance during traffic surges.

VPS hosting: VPS offers customers their own virtual server environment, complete with their own operating system and full control over configurations and software installations. This offers you a stable and isolated environment that boosts site performance, which is ideal for websites with consistent traffic levels. On the other hand, cloud hosting stands out for its incredible flexibility because it allows resources to scale up or down instantly based on your site’s demand. This makes cloud hosting a perfect match for websites that experience frequent traffic fluctuations or have growing needs. It adapts quickly and efficiently and ensures smooth performance across different loads. Both options offer significant control and security, but cloud hosting’s ability to handle large-scale and rapid changes gives it an edge in dynamic scenarios.  Since Bluehost offers Cloud hosting, here’s an overview of the plans:  

What is VPS hosting used for?

VPS hosting is used for eCommerce websites, software-as-a-service (SaaS) providers, agencies, programmers and developers that build more than one website. Basically, you should consider VPS hosting if a shared hosting plan doesn’t give you the resources you need for your website.

Benefits of VPS hosting

Storage and bandwidth 

VPS hosting allocates a specific amount of storage and bandwidth per web server for each user. This ensures you’ll have enough resources to run your website.  

Server control 

In shared hosting plans, users typically have limited access to the server environment. This is because the hosting provider sets the conditions and parameters for the plan. For example, website owners on a shared plan cannot reconfigure their server settings.  

VPS hosting provides you with complete control over the server, allowing you to:  

1. Install custom software or applications.  
2. Configure the website infrastructure.  
3. Add security features.  
4. As a trade-off, you’re in charge of maintaining and upgrading resources if you go with an unmanaged VPS plan (more on that later).  

Customizable server environment 

A VPS allows users to install a preferred operating system and specific applications, giving full customization over the hosting environment. Whether you require unique server configurations or special software, VPS hosting can accommodate it, creating an optimal setup for your website’s needs. 

Root access and control panel options 

With VPS hosting, users gain root access to the server, offering complete administrative control over their hosting environment. This level of access is crucial for advanced users who need to configure server applications, manage files directly and install or remove software. Most VPS providers also offer control panels, such as cPanel or Plesk, for easier management. 

Control over server configuration 

With VPS hosting, you control your server configuration. This capability allows you to manage software updates, install applications and adjust server settings, which is ideal for advanced users requiring custom setups for specific applications or performance optimizations. 

Reliability 

VPS hosting rarely relies on a single server.  

Thanks to virtualization, servers are made up of multiple nodes. So, if one node crashes, there is still a backup. This is a great feature for eCommerce websites, as downtime can be costly.  

Using a virtual private server guarantees high performance by eliminating risks, such as suddenly running out of storage, which commonly happens when you use shared hosting.  

Resilience against high traffic and demand 

The infrastructure behind VPS hosting can handle high traffic and resource demand better than shared hosting environments. This resilience makes VPS ideal for websites expecting growth or seasonal traffic spikes, where stable performance and quick response times are critical. 

Better performance for high-traffic websites 

For websites experiencing higher traffic, VPS hosting offers reliable performance without the limitations of shared hosting. By having dedicated resources, your website can handle traffic spikes more effectively, ensuring a smooth experience for visitors and reducing bounce rates. 

Flexible hosting solutions 

VPS hosting suits various use cases, from eCommerce websites needing security and scalability to applications requiring custom server configurations. The flexibility of VPS hosting allows you to adapt your server setup according to your needs, making it a versatile choice for many industries. 

Privacy and security 

VPS hosting is more secure than standard shared hosting because of the virtual partitions that separate websites from each other. Users have less risk of “contamination” from compromised sites because the other websites are isolated from each other.  

With a VPS hosting provider, you have more control over your website’s security. However, some web hosting providers also offer essential security features or may assist with maintenance. For example, Bluehost includes free SSL certificates and DDoS protection on VPS plans. In addition, it also offers weekly offsite backups to protect your data against loss or corruption.  

Adaptable scalability 

Flexibility and scalability are some of the best benefits of VPS hosting.  

Whenever you need additional resources, you can easily add or borrow from another VPS if needed. This easy scalability is thanks to the hypervisor, which enables the host computer to support other servers and virtual machines by sharing its resources.  

Dedicated resources 

Each VPS provides dedicated resources, including CPU, RAM and disk space, unlike shared hosting, where resources are shared among users. This setup ensures that your website’s performance isn’t impacted by other sites on the same physical server, resulting in faster loading times and a more stable user experience. 

Isolation from other websites 

A VPS is isolated from other virtual servers, meaning your website operates in a dedicated environment. This reduces the risk of server errors caused by neighboring sites, a common issue in shared hosting. This isolation is critical for business websites where performance and security are priorities. 

Cost-efficiency compared to dedicated hosting   

While VPS hosting is more expensive than shared hosting, it remains more cost-effective than a dedicated server, where you pay for an entire physical server. VPS hosting strikes a balance by offering dedicated resources on a virtual machine at a fraction of the cost, making it an economical solution for those seeking greater control and performance without the high expense of dedicated servers. 

Enhanced technical support 

Most VPS hosting providers offer dedicated technical support for managed VPS plans, helping with server management and troubleshooting. For businesses without in-house technical expertise, managed VPS hosting is invaluable, as it includes maintenance and updates, allowing you to focus on growing your website.

Summing up: What is VPS hosting and how does it work?

VPS hosting plans are a great way to get more website security, storage, control and bandwidth without the hefty price tag of a dedicated server. But it’s crucial to choose the best VPS plan for your needs. 

If you’re pressed for time and would rather have a professional handle your server, choose a fully managed VPS plan.
