VPS: Complete Guide to Speed, Security and Optimal Performance

Reading Time: 4 minutes

A VPS (Virtual Private Server) it is a virtual machine that runs independently within a physical server.

About this physical server there are multiple VPS, that is, more “virtual machines”, which they share the same infrastructure, but each one has its own resources allocated separately, such as CPU, RAM, and disk space.

A customer who has a VPS can use its dedicated resources, just like with a dedicated server: ha your own CPU, your own RAM, your own disks. Furthermore, it can install any operating system within the VPS (usually those without a graphical interface are used, because they use less RAM).

I main advantages of the VPS are:

• Scalability and flexibility: they can change the VPS resources at any time, based on needs.
• Lower costs: there are no purchase and maintenance costs for a dedicated physical server.

When it comes to hosting, one of the most versatile and powerful tools available to companies and professionals is the VPS (Virtual Private Server). This solution represents a perfect balance between performance, autonomy and safety, positioning itself between shared hosting and the dedicated server.

Why choose a VPS?

Constant and optimized performance

With a VPS you don’t share resources with other users. Your CPU, RAM and disk space are always available for your project. Result? Faster loading times, even in the presence of traffic peaks.

Greater security

Isolation between VPS protects you from problems that can occur on other virtual environments. Furthermore, you can configure customized security systems and independently manage access, firewall and backup.

Flexibility and scalability

Do you need more resources? With VPS you can increase CPU, RAM or disk space at any time, without interruptions. Perfect for evolving projects.

Maximum control

With full root access, you can install specific software, choose the most suitable operating system (even lightweight versions, without a graphical interface) and customize the server environment according to your needs.

When is the right time to upgrade to a VPS?

And VPS is the ideal solution with:

• your website or e-commerce has growing traffic,
• manage multiple web projects at the same time,
• develop complex applications,
• you want technical and infrastructural autonomy.

We talked about in one of our latest articles Shared Hosting. As you have seen, the differences compared to one VPS There are. However, this does not mean that one solution is worse than the other, but simply that it adapts to different contexts.

Below is a table that compares three types: shared hosting, VPS and dedicated hosting. This way you will be able to see the real differences and start understanding the solution that might be best for you.

Characteristic	Shared Hosting	VPS (Virtual Private Server)	Dedicated Hosting
Resources available	Resources shared with other users on the same server	Dedicated resources (CPU, RAM, disk space) in an isolated virtual environment	Hardware resources totally dedicated to a single user
Performance	Limited and influenced by the traffic of other sites on the server	High and stable thanks to resources allocated exclusively to the VPS	Maximum performance guaranteed, independent of other users
Safety	Low separation between users	Isolation between VPS. Greater security than shared	Complete isolation and manageable security at the hardware/software level
Scalability	Limited	High. Resources can be increased easily	Scalability possible, but less flexible than VPS
Access and control	No root access. Limited management	Root/admin access available	Full root access and total control
Cost	Economic	Intermediate	High
Maintenance	Managed by the provider	Managed by the provider (Managed) or by the user (Unmanaged)	Generally managed by the user or with a dedicated Managed service
Software customization	Limited	High freedom	Total freedom
Ideal for	Blogs, small sites, low traffic projects	E-commerce, corporate sites, agencies, developers	Mission-critical projects, large portals, complex enterprise systems

What needs to be done with a VPS to ensure optimal speed, security and performance?

Below we show some steps to follow to maximize the performance of your VPS.

Speed ​​optimization

To obtain the best performance in terms of speed, it is important:

• Choose a lightweight and up-to-date operating system: Many choose Linux distributions without a graphical interface to save resources (RAM and CPU).
• Use high-performance server software: for example, Nginx or LiteSpeed instead of Apache in high-traffic contexts.
• Configure the cache correctly:
  • Lato server cache (es. OPcache, Redis, Varnish).
  • Application level caching (e.g. caching plugins for CMS like WordPress).
• Optimize databases (e.g. MySQL or MariaDB), regularly executing:
  • Correct indices.
  • Cleaning up slow queries.
  • Tuning of configuration parameters (buffer, thread, pool).
• Monitor resource usage (RAM, CPU, disk) to avoid bottlenecks.
• Use fast storage (preferably SSD or NVMe disks).

Strengthen security

To protect your VPS from vulnerabilities, attacks and intrusions, it is essential:

• Configure firewall and access rules (is. UFW, iptables, CSF).
• Restrict SSH logins:
  • Change the default SSH port.
  • Disable direct root access.
  • Use authentication with chiave SSH instead of the password.
• Install and update all packages and services regularly.
• Configure an IDS/IPS system (Intrusion Detection/Prevention System).
• Monitor system logs to identify suspicious activity.
• Use SSL/TLS certificates to protect data transmission.
• Make regular, automated backups to ensure recovery in the event of an accident.
• Protect web applications with tools like Fail2Ban, ModSecurity, etc.

Improve overall performance

In addition to speed, overall performance depends on:

• Proper allocation of VPS resources (RAM, CPU, disk) based on the actual load.
• Tuning the operating system and the web serverto better manage requests.
• Competition management: For example, configure correctly workers/processes to support multiple users at the same time.
• Use a Content Delivery Network (CDN) to lighten the load on your VPS and serve static content faster around the world.
• Monitor in real time the use of resources
• Eliminate unnecessary or unused services to free up resources.
• Periodically update software and configurations to keep the system always efficient.

Discover the power of your new infrastructure
