How to choose PrestaShop hosting

A complete guide on how to choose professional Prestashop hosting for optimal user experience and performance

Choose a service hosting for your PrestaShop site It's a crucial decision that can have a significant impact on the performance of your online store and, consequently, your business. In an increasingly competitive market, speed and security have become top priorities. In this article, we will explore the key factors to consider when choosing hosting for PrestaShop, with a particular focus on the importance of fast hosting, low Time to First Byte (TTFB), and an advanced software stack.

The importance of Fast Hosting and Low TTFB


A fast website is not just a matter of user experience; it is also a factor that can affect your search engine rankings. Google has made it clear that site speed is a ranking factor, and a low TTFB (Time to First Byte) is an indicator of a fast and responsive server. This parameter is fundamental because it represents the first contact between the user and your site; a high TTFB can lead to a negative user experience, increase abandonment rate, and ultimately negatively affect your ranking in search results.

TTFB is the time between the client's HTTP request and receiving the first byte of data from the server. In simple terms, it's how long it takes for the server to start sending data in response to a request. A low TTFB means that the server is able to respond to requests quickly, which is crucial for any online store, especially during peak traffic like Black Friday or the Christmas period. During these times, even a small delay in server response can result in lost sales and an unsatisfactory user experience.

But TTFB is just the tip of the iceberg when it comes to site performance. Other factors such as download speed, page load time, and network latency play a significant role in the overall user experience. That's why it's crucial to choose a hosting service that not only offers a low TTFB but also a full suite of performance optimizations, such as server-level caching, image optimization, and data compression.

Additionally, fast hosting with a low TTFB is often the result of a well-designed infrastructure, including high-quality hardware, an optimized network, and well-configured server software. These elements work together to ensure that every aspect of your site is optimized for speed, from the initial server response to the final page load.

An Advanced Software Stack

When it comes to hosting for PrestaShop, it is crucial to have a software stack optimized for performance. Here are some key components:

Webserver: NGINX

NGINX Banners

NGINX is known for its high performance and its ability to handle large numbers of simultaneous connections. It is faster and more efficient than other web servers like Apache. This efficiency is largely due to its asynchronous, event-based model, which allows it to successfully address the C10K problem, the challenge of managing tens of thousands of connections simultaneously. While servers like Apache use a thread- or process-based model, which can become inefficient and resource-expensive with a high number of connections, NGINX was designed to minimize CPU and memory usage, making it extremely scalable. This scalability is one reason why NGINX is used by web giants like Wikipedia, Facebook, Amazon, and Alibaba. It has become the reference standard for enterprise web servers and is used by the most important companies worldwide to guarantee performance, security and reliability.

PHP in FPM mode

PHP-FPM (FastCGI Process Manager) is an advanced, highly customizable mode for running PHP, designed for optimal performance and efficient resource management. Unlike traditional ways of running PHP, such as mod_php in Apache or CGI, PHP-FPM allows for more flexible and scalable handling of client requests.

One of the main features of PHP-FPM is its ability to manage pools of workers, which can be pre-started and kept waiting for requests. This eliminates the overhead associated with starting a new process or thread for each new request, as happens in other models. In practice, this translates into reduced latency and increased throughput, factors that are crucial for any high-performance web application, such as an online store on PrestaShop.

Additionally, PHP-FPM offers a number of configuration options that allow you to further optimize performance. For example, you can adjust the number of child processes, manage persistent connections, and configure worker pool behavior in detail. This flexibility makes PHP-FPM suitable for a wide range of scenarios, from small websites to large e-commerce sites with millions of users.

Another advantage of PHP-FPM is its compatibility with the most modern and high-performance web servers, such as NGINX. This combination is particularly powerful, as both are designed with an asynchronous and event-based architecture, allowing for extremely efficient and scalable resource management.

Full Page Cache: Varnish

Varnish Cache assistance

Varnish is a high-level HTTP accelerator that acts as a cache for your website, aiming to significantly reduce load on the backend server and dramatically improve page loading speed. It is especially useful for websites with a high volume of traffic and for applications that require very low latency.

One of Varnish's main strengths is its configurability. Using the Varnish Configuration Language (VCL), you can fine-tune how Varnish handles HTTP requests and responses. This gives you granular control over which items are cached and for how long, allowing you to optimize the cache based on the specific needs of your website or application.

Varnish is also designed to be extremely fast. It uses RAM memory to store data, meaning requests can be fulfilled almost instantaneously. This speed is especially valuable in scenarios where it is critical to serve a large number of users at once, such as during high-traffic sales events like Black Friday or the Christmas season.

Another key aspect of Varnish is its ability to scale horizontally. It can be easily integrated into more complex architectures, including those that use load balancers, making it easier to manage traffic spikes and expand as business needs.

In combination with other high-level components, such as NGINX and PHP-FPM, Varnish can offer an extremely performant and reliable environment. This combination is often considered a sort of ÔÇťsacred triadÔÇŁ for web performance, providing a comprehensive solution that improves not only page loading speed, but also resource efficiency and resilience to performance issues.

L3 and L7 DDOS protection

A good hosting service should offer DDoS protection at layers 3 (network) and 7 (application) to ensure your site is always accessible, even during a DDoS attack. Layer 3 DDoS protection focuses on blocking malicious traffic at the network level, filtering unwanted data packets before they reach your server. This is particularly effective against volumetric attacks that seek to overload the network with a huge amount of traffic.

On the other hand, layer 7 protection is designed to defend against more sophisticated attacks that target the application itself. These attacks can include attempts to exploit vulnerabilities in the application code or web server, and require a more advanced defense that goes beyond simple traffic filtering. Level 7 protection can include a variety of measures, such as rate limiting, HTTP request filtering, and behavioral analysis to identify and block suspicious activity.

Having both types of DDoS protection is critical to a 360-degree defense. While Layer 3 protection can block most malicious traffic, Layer 7 protection is necessary to defend against more targeted and sophisticated attacks that may evade network-level filters.

Additionally, a hosting service that offers comprehensive DDoS protection should also provide real-time monitoring and alerts to inform you of potential attacks. This allows you to react quickly and coordinate with the support team to mitigate the attack before it can cause significant damage.

Systems consultancy

Before making a choice, it is highly advisable to obtain systems consultancy. This phase is crucial for identifying critical issues, shortcomings and room for improvement. The consultancy must consider various factors such as:

  • Number of products
  • Maximum number of visitors in real time
  • High traffic times of the year
  • Origin of visitors
  • Need for an enterprise-class CDN for sites of international interest

Systems consulting is an in-depth process that takes various key factors into consideration. One of them is the number of products offered on your site. A larger catalog may require more system resources and greater capacity to handle a large number of database queries.

Another critical factor is the maximum number of real-time visitors. This data is essential to correctly size the infrastructure and to ensure that the site can handle traffic peaks without degrading performance.

Counseling will also need to consider high traffic times of the year, such as Black Friday or the Christmas period. These events can place a strain on server resources and require careful planning to avoid service interruptions.

The geographic origin of visitors is another aspect that must be taken into consideration. If your site appeals to an international audience, you may need to implement an enterprise-grade Content Delivery Network (CDN) to ensure fast load times and a consistent user experience around the world.

24 hour assistance and response time

system assistance


A support service available 24 hours a day, with a response time of less than 24 minutes for critical problems, is a huge advantage that goes far beyond simple convenience. In an online environment, where every minute of downtime can result in significant revenue losses and reputational damage, the speed and effectiveness of technical support is critical.

24-hour availability ensures that regardless of your time zone or working hours, there will always be a team of experts ready to assist you. This is especially important for online stores and platforms that serve a global audience, where problems can arise at any time of day or night.

A rapid response time, especially for critical issues such as server failures or DDoS attacks, is essential to minimize the negative impact on users and business. A response time of less than 15 minutes can mean the difference between a minor inconvenience and a full-scale crisis that could take hours or days to resolve, resulting in lost revenue and customer trust.

Additionally, high-quality support doesn't just fix problems once they've occurred; often also includes proactive monitoring to identify and prevent potential problems before they become critical. This type of proactive support can include everything from monitoring server performance to scanning for potential security vulnerabilities, providing an added layer of protection and peace of mind.

Backup and Disaster Recovery


Having remote geographic duplicate backups and a proven disaster recovery plan is essential to ensure business continuity and data protection. In an age where data is one of an organization's most valuable assets, its loss or corruption can have devastating consequences, both in financial and reputational terms.

Remote geographic dual copy backups offer an additional layer of security, ensuring that data is stored in more than one geographic location. This is especially useful in the event of catastrophic events such as fires, floods, or other natural disasters that could compromise an entire data center. Having a copy of your data in a geographically separate location can be the key to a quick and effective recovery.

A proven disaster recovery plan, on the other hand, is a set of procedures and policies designed to quickly restore operations and data in the event of a system failure or other type of disaster. A well-designed plan should be tested regularly to ensure it is effective and to identify any areas for improvement. It should also be flexible enough to adapt to various types of disaster scenarios, from simple hardware failures to large-scale outages.

Furthermore, compliance with the GDPR (General Data Protection Regulation) is a must for any company that processes personal data of European Union citizens. In addition to ensuring that data is treated securely and confidentially, the GDPR also requires that companies have procedures in place to notify the authorities and affected individuals in the event of a data breach. Having GDPR compliant backups and disaster recovery plans is not just good practice; it is also a legal necessity.


Choose a hosting for PrestaShop it's a process that requires careful consideration of various factors, from technical infrastructure to customer support. Fast hosting with a low TTFB and an advanced software stack will not only improve the performance of your site but also contribute to the success of your online business. Don't underestimate the importance of systems consultancy to make the most informed choice suited to your specific needs. With excellent support and a robust backup and disaster recovery plan, you will be well positioned to deliver a high-quality user experience and excel in an increasingly competitive online marketplace.
