1. Understanding What Is A Virtual Private Server
So, what is a VPS, exactly? Let’s dive into the core components of a Virtual Private Server to gain a clearer understanding:
- Server: Imagine a server as a robust computer that tirelessly stores all the essential data and files that constitute a website. When you input a domain name into your browser, this server promptly delivers the site to your screen, ensuring seamless accessibility.
- Virtual: Embracing virtualization technology involves ingeniously dividing a single, comprehensive server into multiple virtual machines. While it remains a unified physical hardware component, it adeptly functions as several independent servers, optimizing resource utilization.
- Private: The term “private” accurately conveys its essence. Your virtual server, along with all its virtual resources, is exclusively reserved for your use. This exclusivity cultivates a high-performance hosting environment, ensuring that vital resources like RAM, CPU power, and data remain unshared with other users.
A VPS offers a compelling advantage by providing the benefits of dedicated servers while avoiding the substantial costs associated with dedicated hosting. This makes it an appealing choice for businesses seeking enhanced performance without straining their budget.
2. Exploring How Does A VPS Work
VPS hosting utilizes virtualization technology, allowing you to simulate your own dedicated server while sharing a physical server.
Here’s how it operates:
Your hosting provider sets up a virtual layer on top of the server’s operating system. This layer divides the server into distinct sections for each user, creating virtual machines (VMs).
Inside each compartment, you can set up your chosen operating system, software, and other tools needed to host your website, such as Linux, MySQL, and a control panel like cPanel.
These virtual machines ensure you receive guaranteed resources. Unlike shared hosting, your server’s performance doesn’t depend on other websites’ resource usage on the same server.
In short, VPS gives you the feeling of having your own dedicated environment through virtualization. Your website lives in a private, isolated container with resources assigned only to you.
This means your website is in a safe container with ensured server resources like memory, disk space, and CPU cores. You don’t have to share any of it with others.
3. Weighing The Pros And Cons Of VPS Hosting
A virtual private server gives dedicated resources and greater control over server settings compared to shared hosting, at a lower cost than dedicated hosting. VPS finds a good balance of affordability, customization, and ensured performance for many growing websites and web applications.
3.1. Advantages of Using a VPS Server
- Cost-Effectiveness: VPS is cheaper than dedicated hosting but gives better performance than shared hosting. VPS is a budget-friendly choice for websites growing beyond shared servers.
- Customization and Control: VPS users can fully improve and change server settings, and set up software. This level of control is great for websites with specific setup needs.
- Scalability: It’s easy to scale VPS resources like CPU cores, RAM, and storage as website traffic increases. Websites can upgrade their VPS plan as needed to handle growth.
- Dedicated Resources: VPS gives ensured CPU, RAM, bandwidth, and disk space. Resources are not shared, ensuring full control and reliable performance.
- Enhanced Security: VPS isolates websites from each other for added security compared to shared hosting’s open environment.
- Support and Maintenance: Many VPS plans include technical support and management options to maintain the server.
3.2. Disadvantages of Using a VPS Server
- Technical Expertise Required: Managing and improving a VPS requires strong technical skills. Those without server admin experience may struggle.
- Resource Allocation Problems: Improper resource allocation by the hosting provider can impact VPS performance.
- Limited Hardware Control: Users don’t control the physical server since VPS virtualizes hardware.
4. VPS Compared With Shared Hosting and Dedicated Hosting
When selecting a web hosting plan, there are three main options: shared hosting, dedicated hosting, and VPS hosting. Let’s examine the key differences.
4.1. Shared Hosting
Shared hosting is the most common and the most cost-effective form of web hosting and works well for most new website owners. When you purchase a shared hosting plan, you’re sharing resources like CPU, RAM, and hard drive space with other website owners on that same server.
Consider shared hosting as multiple websites renting a single apartment in the same building. Each of you gets your own private bed, but you share the apartment with common spaces like the lobby, elevators, and utilities. In the case of websites, it’s CPU, RAM, and storage.
This offers multiple benefits, including lower costs, as the server costs are split among all the website owners. If one of the websites on your shared server has a huge spike in traffic, that could affect your website’s performance as well.
But when you’re just getting started, you are unlikely to notice the impact.
4.2. Dedicated Hosting
Dedicated hosting allocates an entire server to just your site. You have full control over resources and can customize them to meet your needs.
With dedicated hosting, you are no longer pooling resources (and sharing the costs) with other website owners.
Sounds great, right? The catch is that it’s much more expensive — but you get 100% control over your resources and can customize the software to meet your individual needs.
This type of hosting package is best for websites with robust technical demands. Some examples where dedicated hosting could be beneficial:
- Websites with high-traffic volume
- Sites handling large financial transactions
- Custom software requirements
- Need for specific operating system
Dedicated hosting is the optimal solution for sites that demand unparalleled performance and specificity.
4.3. VPS Hosting
VPS hosting provides a middle ground between shared and dedicated. When you choose VPS, other websites will be hosted on the same hardware as yours.
But now, your website is running on a virtual machine with its own dedicated resources. That means you get your own operating system, dedicated storage, powerful CPU, scalable RAM, and unlimited bandwidth.
Thinking of it from the apartment complex analogy, consider all apartment owners now have access to their private lobbies, elevators, and utilities. One person using the resource no longer impacts the rest.
This provides you with the double benefits of dedicated hosting, where you have complete control over the resources and lower costs because of the shared physical servers.
5. Recognizing When Should You Switch To VPS
If your website is growing, you may wonder: should you upgrade to VPS? Here are key signs that can indicate you’re now ready to make the switch.
5.1. Enhanced Security Needs
Shared hosting offers basic security, but VPS delivers if you need more advanced features like firewalls, SSL certificates, or daily backups. This is particularly true for sites that process payments or store sensitive data. VPS gives you top-notch security features for the complete safety of your website.
5.2. Experiencing High Traffic Volume
Shared hosting is great when you’re just starting out and have a low visitor count, but it can struggle and slow down when your site has large spikes in traffic. With VPS, you get dedicated resources (CPU, RAM, bandwidth, etc.) that can smoothly handle those traffic swells.
5.3. Consistent Website Slowdowns
On shared servers, you’re fighting for resources with other sites. As you add more content over time, you can max out limits for things like RAM. Suddenly, pages take forever to load.
A VPS gives you plenty of room to continue scaling your business without frustratingly slow load times.
5.4. Running An Online Store
The moment you plan on running an online store is the moment you should upgrade your hosting plan.
Why?
Because with VPS, you have a secure and dedicated virtual server where you are more likely to pass a PCI compliance test. The Payment Card Industry Data Security Standard was established by major credit card brands to protect against cardholder data theft.
If you are accepting credit cards on your website via a payment gateway, you want to do everything you can to ensure the safety of your consumers’ financial information.
Since VPS is more secure than shared hosting, it’s the better option for e-commerce websites.
5.5. Custom Software Installation
Shared hosting is great for website owners building their site with WordPress or other Content Management Systems. However, suppose you reach the point where you need to install custom software, engage in any other advanced programming, or use a custom server configuration. In that case, you’ll want a hosting option that affords you more control.
Similarly, several standard tax, billing, bookkeeping, and other integrative programs require around-the-clock server availability as well as high-speed internet. You’ll need a VPS or a dedicated hosting account to run these applications successfully.
If you operate on a shared server, you’ll only be frustrated when you learn advanced actions are forbidden, or that apps don’t have the support to function properly. Instead of dealing with this potential problem, upgrade to VPS hosting and immediately gain more control over your programming actions.
5.6. Frequent Server Errors
Do you often see 503 or internal server errors?
It’s highly likely your customers see those, too. These errors generally indicate that your server is experiencing difficulties serving the website.
While you can troubleshoot downtime issues, every minute of downtime costs money for your online business. Instead, upgrading your resources usually offers better time-to-value for your business.
5.7. Budget Considerations
While it’s true that a dedicated hosting package can address many of the problems on this list, it’s important to remember that a dedicated plan is a much pricier option. If you need to improve your bandwidth, increase your security, and get more RAM, then the most affordable option is to opt for VPS hosting.
5.8. Website Development for Clients
Shared hosting can be great for building personal or portfolio websites. It’s simpler to manage and offers lower costs. But when handling client websites, you do not want a slow server to impact them.
VPS hosting provides you with high-powered servers so you can host unlimited websites without worrying about performance.
6. Steps To Choose The Best VPS Hosting Plan For Your Website
Now, let’s understand how you can find the best web hosting provider and the perfect VPS hosting plan for your needs. Before you begin, you need to pick between self-managed and managed VPS servers.
6.1. Self-Managed Vs. Managed VPS Services
When selecting a VPS hosting, you will usually be presented with two options:
- Self-managed VPS service (sometimes called unmanaged VPS)
- Managed VPS service
With self-managed VPSs, you need to understand server administration, troubleshooting software, and managing apps and services installed on your VPS.
Managed VPSs, on the other hand, are an excellent choice when you are unfamiliar with these admin skills or you just want your hosting company to handle it for you.
All of DreamHost’s VPS plans are fully managed, meaning you can skip worrying about the intricate technical details and focus on what really matters: creating great content for your website.
If you’re looking for root access, consider opting for DreamHost’s cloud hosting.
Now, let’s understand other options you’ll be faced with when picking a VPS server.
6.2. Operating System
Most VPS hosts offer Linux-based operating systems. This could include Ubuntu, Debian, CentOS, or Red Hat Linux.
The reason? Linux is open-source, stable, secure, and flexible.
Windows VPS exists but is less common. You likely only need Windows if you use Windows-specific software. Linux VPS offers the most reliability, which is why most hosting providers only offer Linux VPS.
6.3. Reliability and Uptime
Your VPS host should guarantee an uptime of 99.5% or higher in their SLA. Anything less could result in unacceptable downtime and impact your business. Preferably, look for hosting providers that offer 100% uptime guarantees, load balancing, redundancy, and failover to deliver maximum reliability.
6.4. Hardware and Resources
Select a VPS host using modern hardware for optimal performance—SSD storage, abundant RAM and bandwidth, multi-core processors, etc. Scalability is also important to allow seamless upgrading of resources as your site grows. Make sure the VPS specs match your website’s resource needs.
6.5. 24/7 Customer Support
Even with managed services, website issues can occur unexpectedly. Ensure your VPS provider offers 24/7 customer support via phone, chat, and support ticketing in case you need immediate assistance. Prompt support is crucial for minimizing downtime.
6.6. Backup Service
Choose a host that includes automated daily or weekly backups to prevent data loss. Managed hosting providers generally handle backups in the background without any effort on your part. However, remember that you still need to check with the support on your backups’ frequency and retention period.
Generally speaking, the more frequently your website changes (like a community website where many people post every day), the more frequent your backups need to be.
