Beyond Shared Hosting: Multi-Site VPS Hosting Demystified

Before hosting my site into VPS, I was using shared hosting. Over time, I discovered I couldn’t do many things in my shared hosting, for example, installing object cache and many other things.

I realize moving on to dedicated servers is expensive and unnecessary for small and personal websites. Then I found VPS and decided to move on, which offers a balance between shared hosting and dedicated servers.

What comes with a VPS? In a nutshell, a VPS is a partitioned portion of a physical server with its own operating system, storage, and bandwidth, providing you with greater control and flexibility than shared hosting.

This makes a VPS an attractive option for hosting multiple websites, especially for small businesses and developers.

The goal of this blog post is to share experiences and talk about the pros and cons of running multiple sites on a single VPS, as well as the security measures that must be taken.

Why VPS and Not Shared Hosting?

When you’re just starting out with a small website or blog, shared hosting can be a good option. However, as your site grows, you might face challenges because of the limitations of shared hosting.

So when you are using shared hosting, you are actually sharing the server resources with many other websites on the same server. This can lead to performance issues if other sites on the server experience heavy traffic. You also have little control over the server setup, which could be a problem if you need to use specific technologies and tools for your site.

A VPS, on the other hand, gives you your own dedicated portion of a server’s resources. This means better performance and more flexibility. You can configure the server the way you want, and you won’t be affected by traffic surges on other sites.

And when I decided to launch other sites, I didn’t need to purchase different hosting for my new sites instead, I’m using my existing VPS to host my other websites. So, VPS can be a cost-effective solution if you manage several sites.

Risks and Downsides

While there are clear advantages, there are also potential downsides and risks associated with hosting multiple sites on the same VPS:

Resource Sharing: Each website hosted on the VPS will share the server’s resources, such as CPU, RAM, and storage. If one website sees a surge in traffic, it could consume more resources, potentially slowing down other sites on the same server.

Security Risks: If one of the websites on the VPS is hacked, it could put other websites on the same server at risk. For example, an attacker could use a vulnerability on one site to get access to others.

Actionable Steps to Secure Multiple Sites in VPS

While using VPS, you should take care of many things by yourself, including the security of the VPS. Securing your VPS server might not be as hard as it seems. Here are a few recommendations:

Regular Updates

For security, it’s important to keep your server’s operating system, and software should be up-to-date. Updates often include patches for known security vulnerabilities that attackers could exploit. Also, if you’re using a CMS like WordPress for your sites, ensure you regularly update it along with its themes and plugins.

Separate User Accounts

Even though your sites are on the same server, using different user accounts for each website is a good idea. This protects other sites even if one site is compromised.

Server Hardening

This includes steps such as setting up a firewall, disabling unnecessary services, using SSH keys for authentication, and keeping your server software minimal and up-to-date.

Use of Security Plugins

If you’re using WordPress, several excellent security plugins are available. These plugins can help protect your sites from common attacks such as brute force login attempts and SQL injection attacks.

Regular Backups

No matter how secure your server is, there’s always a risk that something will go wrong. Regular backups prevent data loss in case of a security breach. Be sure to keep multiple versions of your backups and store them in a secure, off-site location.

SEO Considerations for Multiple Websites on a Single VPS

If SEO is important, you should consider the potential SEO issues when hosting multiple sites on a single VPS. A common question is whether sharing an IP address across multiple sites can impact your SEO.

According to Google’s algorithm, sharing an IP address among multiple sites doesn’t inherently affect your search rankings. However, if one of the sites engages in spammy behavior that leads to the IP address being blacklisted, it could potentially impact all sites associated with that IP.

To ensure the best SEO results for your sites, follow these tips:

  • Maintain Fast Load Times: Overcrowding your VPS could slow down your websites, which can affect user experience and SEO. Monitor your server resources and upgrade as needed to ensure optimal performance.

  • Use Reliable Hosting: Uptime is a very important part of SEO. Make sure your VPS provider has a strong reputation for reliability.

  • Secure Your Sites: Google may penalize sites that are insecure or compromised. Follow the security practices outlined earlier to keep your sites safe.

  • Implement SSL: Google gives a ranking boost to HTTPS sites. Ensure every site hosted on your VPS uses SSL.

Wrapping Up: Is VPS the Right Choice for You?

Hosting multiple websites on a single VPS offers several advantages, including cost-effectiveness, flexibility, and greater control over your hosting environment. However, it does come with its share of risks, such as potential resource sharing issues and increased security vulnerabilities.

By implementing robust security measures and best SEO practices, you can effectively mitigate these risks and maximize your VPS. Whether you’re a small business owner, a developer, or a blogger, a VPS could be the perfect solution for managing multiple websites efficiently.

We hope this article provides valuable insights into the considerations for hosting multiple websites on a single VPS.
