What Is Hosting: What It Is Used For and What Types Exist

Hosting, also known as web hosting, is the service that allows a website's files, images, databases, and other content to be stored on a server permanently connected to the Internet.

Simply put: if the domain is your site's address, hosting is the place where its content lives.

When someone enters your domain in a browser, the hosting server receives the request and delivers the files needed to display the page.

That's why publishing a website requires two essential elements: a domain, which identifies the site's address, and a hosting service, which stores and serves its content.

What is hosting used for?

Hosting allows a website to be available on the Internet.

When you sign up for a hosting service, you get space and resources on a server to store your site's files, databases, emails, and other components required for it to function.

Without hosting, your website's files could exist on your computer, but no one would be able to access them over the Internet.

A good hosting service also provides resources related to performance, security, backups, administration, and technical support.

Physical servers located in the data center. This is where website files are hosted and delivered ("served") to users (site visitors) through the hosting service.

How does hosting work?

When someone visits a website, their browser connects to the server where it is hosted and requests the files needed to display the page.

The server processes the request and delivers HTML, images, stylesheets, scripts, and data to the visitor's device.

All of this normally happens in a fraction of a second. That's why the server's speed, connectivity, storage, and hosting configuration directly affect a website's performance.

Professional servers operate inside data centers equipped with redundant connectivity, backup power, cooling, and physical and digital security measures.

Racks filled with web servers, always kept in refrigerated and fire-resistant environments.

Web hosting is a service offered by specialized companies that provide server space to store and publish websites on the Internet. These servers—high-performance computers located in data centers—operate in controlled environments with constant cooling, stabilized power, and strict physical security measures.

In addition to the physical environment, these centers have permanent Internet connectivity through redundant high-speed links, allowing hosted websites to be accessible from anywhere in the world, 24 hours a day, 365 days a year.
This entire set of resources—infrastructure, connectivity, and environmental control—is what guarantees the stability, speed, and continuous availability of hosted websites.

What is the hardware of a hosting service like?

The server's hardware plays a fundamental role in the speed and stability of hosting. Components such as the CPU determine how many simultaneous visits a site can handle without degrading its performance. On our servers, for example, we use high-end processors such as AMD EPYC and Intel Xeon Gold, specifically designed for demanding web workloads.

What is the difference between a domain and hosting?

The domain and hosting serve different purposes, but they work together.

The domain is the address a person enters to access the site, for example duplika.com.

Hosting is the service that stores the site's files and data and delivers them when someone visits that address.

You can think of it this way: the domain is a house's address, and hosting is the house and the space where you keep all its contents.

You can register a domain with one company and purchase hosting from another; the two connect through DNS configuration.

What happens when we enter a web address

When you type a web address into the browser's address bar—for example, duplika.com—this means that you are entering a URL (short for Uniform Resource Locator, that is, the unique identifier that makes it possible to locate a site on the Internet).

That URL acts as a kind of digital coordinate: it tells the browser which server to connect to in order to retrieve the requested content. Your device—whether a computer, cellphone, or smart TV—then sends a request to the web server where the site is hosted, and the server responds by sending the files needed to display the page on your screen: text, images, stylesheets, scripts for special functionality, and so on.

This exchange takes place in milliseconds. While the files are downloading, the browser starts rendering—bringing together and correctly arranging all the elements on the screen—which results in the page loading and being progressively compiled. If the server is efficient and the site is well optimized, all the content can be displayed in less than two seconds.

However, behind that web address and its fast loading is an invisible but crucial infrastructure: the hosting service. Every online project has specific needs—a small online store with thousands of visitors is not the same as a personal blog—so there is no one-size-fits-all solution.

A professional and transparent hosting company should help you choose a plan suited to your site's technical profile: its actual resource requirements, hardware appropriate for its traffic volume, keeping updates current, and other key factors that improve the browsing experience for visitors to your site.

And, in addition to the service itself, it is also important to have tools that make daily site management easier.

That's why, and to make our customers' lives easier, Duplika includes the powerful cPanel in all its hosting plans. This administration tool gives customers full control over their website, email accounts, backups, and many other essential features for managing hosting quickly, simply, and efficiently.

Web space in your hosting

We mentioned that hosting involves disk space as its sine qua non feature. This is no coincidence: hosting literally means “accommodation,” that is, the physical place where your website's files are stored.

This storage space can be based on two major technologies: HDD drives (with mechanically rotating platters) and modern SSD drives (solid-state). How do they differ, and why is this important when it comes to speed?

What is the difference between HDD, SSD, and NVMe hosting?

Servers can use different storage technologies.

HDD uses mechanical disks and is the traditional technology. It offers high capacity at a low cost, but has longer access times.

SSD uses solid-state memory, with no moving parts, and provides much faster access to files.

NVMe is a solid-state storage technology designed to take advantage of higher-speed connections and further reduce latency.

For a modern website, SSD or NVMe provides a clear advantage in speed and responsiveness over a traditional HDD.

Evolution in data storage

To understand this, imagine a vinyl record: the turntable spins, the needle reads the grooves sequentially, and this reproduces the music. This mechanism is essentially similar to how an HDD works: physical platters spin at high speed while a head moves to read (or write) data.

By contrast, an SSD has no moving parts. It is more like an ultra-fast flash drive: it accesses data directly on memory chips, making it much faster, quieter, and more resistant to wear than a traditional HDD.

In the context of hosting, this translates into faster-loading websites, shorter response times, and a better experience for visitors. That's why at Duplika, we work exclusively with SSD drives in all our plans.

HDD hosting is still a deeply established system because it predates SSD and is much more affordable. But each generation of SSD far surpasses the previous one, making the gap between the two technologies barely comparable.

You can immediately identify a mechanical HDD in a desktop computer because it makes noise when reading or writing data: a faint mechanical hum, as if tiny grains of rice were bumping into one another. An SSD is silent.

HDD hosting represents the traditional storage system. Its main advantage remains its low cost, making it an affordable option for those who prioritize budget over performance. However, although modern versions have improved rotational speed to optimize performance, HDD technology faces an insurmountable physical limitation: because it depends on moving mechanical parts—such as motors and read/write heads—it cannot compete with current SSD systems in speed or durability.

The relatively new SSD hosting differs from HDD hosting like night and day: the former uses “solid-state” drives, devices with no motors or spinning disks. With SSDs, there are no moving parts: everything works like a large electronic memory. This means that they make no noise, benefit from a longer lifespan, and—no small advantage—can access multiple files at the same time, just like RAM.

For practical purposes, the difference between HDD and SSD can be compared to this:

→ With an HDD, to make a sandwich, you have to get up from the couch and walk to the kitchen, open the refrigerator, and look for the ingredients one at a time.
→ With an SSD, in one second we fly to the refrigerator, collect all the ingredients at the same time, and have a sandwich after taking 10% of the time required in the previous example.
That's how different these two technologies are.

Of course, this evolutionary leap comes at a price. Storing the same amount of information on an SSD costs, on average, twice as much as on an HDD per megabyte of space.
That's why most hosting providers still do not offer solid-state drives in their plans. At Duplika, on the other hand, we work exclusively with SSDs across all our services.

Types of Hosting

There are different types of hosting services, so the ideal choice will depend on the characteristics and needs of your project.

Shared hosting

This is the most common and affordable type of hosting. Several websites share the same physical server, sharing resources such as CPU, memory, and bandwidth. If the server is properly configured and the site is well optimized, it is an excellent option for starting a project.

In these environments, it is essential that the provider uses technologies such as CloudLinux (as we do). CloudLinux isolates each account to prevent an account malfunction—including infections—from affecting the other sites on the server.

Multi-account / Reseller plans

Reseller hosting plans allow you to create and manage multiple independent hosting accounts from a single platform. This is especially useful for agencies, developers, and professionals who manage sites for different clients.

VPS and Cloud servers

A VPS server uses virtualization, usually KVM or VMWare, to assign independent resources and configurations within a server infrastructure. It offers more control, scalability, and capacity than a shared hosting plan.

Dedicated servers

Unlike the cloud, here the entire physical server is reserved exclusively for the client, with no virtualization layers. It is the most powerful and customizable option, designed for large-scale projects or those with highly specific technical needs.

What is "WordPress Hosting"?

WordPress hosting emerged to support the enormous popularity of this content management system, which powers no less than 43.4% of all websites worldwide (according to W3Techs data). WordPress is software for creating and managing websites, and like all software, it needs a suitable hardware environment and technical configuration.

In this context, WordPress hosting is a hosting service specifically optimized for sites built with WordPress. This means providing sufficient memory, processing capacity, and connectivity, together with a software platform configured so that the site operates with maximum speed, security, and responsiveness.

What should you consider when choosing a hosting service?

Before purchasing hosting, pay particular attention to:

Performance: storage type, CPU, memory, and server technology.

Availability: look for a provider that clearly publishes its uptime commitment.

Technical support: make sure you can contact people who can help when a real problem occurs.

Backups: check how they are performed and how long they are retained.

Security: firewall, account isolation, malware protection, and updates.

Scalability: it should be possible to increase resources or change plans without having to rebuild the entire site.

Transparency: review limits, renewal pricing, and included resources before signing up.
