What Is Hosting? What Is It For, and What Types Are There?

Hosting, also called web hosting, is a service that stores a website’s files, images, databases, and other content on a server that is permanently connected to the Internet.

Simply put: if the domain is your website’s address, hosting is where its content lives.

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

That’s why you need two essential elements to publish a website: a domain, which identifies the site’s address, and a hosting service, which stores and serves its content.

What is hosting used for?

Hosting makes a website available on the Internet.

When you sign up for a hosting service, you get space and resources on a server to store your website’s files, databases, email, and other components needed for it to work.

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, management, and technical support.

Physical servers located in the datacenter. Website files are hosted there and delivered (“served”) to users (website visitors) through the hosting service.

How does hosting work?

When someone visits a website, their browser connects to the server where it’s 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 usually happens in a fraction of a second. That’s why server speed, connectivity, storage, and hosting configuration directly affect a website’s performance.

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

Rows of racks filled with web servers, always in cooled, 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, stable power, and strict physical security measures.

In addition to the physical environment, these centers have permanent Internet connectivity through high-speed redundant links, making it possible to access hosted websites from anywhere in the world, 24 hours a day, 365 days a year.
Together, these resources—infrastructure, connectivity, and environmental controls—ensure the stability, speed, and continuous availability of hosted websites.

What hardware does a hosting service use?

The server hardware plays a key role in hosting speed and stability. Components such as the CPU determine how many simultaneous visits a website can handle without performance degradation. For example, our servers use high-end processors such as AMD EPYC and Intel Xeon Gold, designed specifically for demanding web workloads.

What is the difference between a domain and hosting?

Domains and hosting serve different purposes, but they work together.

A domain is the address someone enters to access a website, for example, duplika.com.

Hosting is the service that stores a website’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 get hosting from another; the two are connected 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—you’re entering a URL (short for Uniform Resource Locator, the unique identifier used to locate a website on the Internet).

That URL acts like a digital set of coordinates: it tells the browser which server to connect to in order to retrieve the requested content. Your device—whether it’s a computer, cell phone, 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 features, and more.

This exchange happens in milliseconds. As the files download, the browser starts rendering—putting all the elements together and arranging them correctly on the screen—which means the page loads and is compiled progressively. If the server is efficient and the site is well optimized, all the content can appear in less than two seconds.

Behind that web address and its fast loading is an invisible but crucial infrastructure: the hosting service. Every online project has its own needs—a store with thousands of visitors is different from a personal blog—which is why there’s no one-size-fits-all solution.

A professional, transparent hosting company should help you choose a plan that fits your site’s technical profile: its actual resource requirements, hardware suited to its traffic volume, keeping software up to date, and other key factors that improve the browsing experience on your website.

And beyond the service itself, it’s also important to have tools that make it easier to manage your site day to day.

That’s why, to make things easier for our customers, Duplika includes the powerful cPanel in all its hosting plans. This management tool gives customers full control over their website, email accounts, backups, and many other essential features, making it quick, simple, and efficient to manage their hosting.

Web space in your hosting plan

We mentioned that hosting includes disk space as an essential feature. That’s no coincidence: hosting literally means “accommodation”—the physical place where your website’s files are stored.

This storage space can be based on two main technologies: HDDs (with mechanically spinning platters) and modern SSDs (solid-state drives). How are they different, and why does that matter for 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, allowing files to be accessed much faster.

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

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

The evolution of data storage

To understand how it works, imagine a vinyl record: the turntable spins, the needle reads the grooves in sequence, and the music plays. A hard drive works in much the same way: physical platters spin at high speed while a read/write head moves to read or write data.

An SSD, by contrast, has no moving parts. It’s more like an ultra-fast USB flash drive: it accesses data directly on memory chips, making it much faster, quieter, and more durable than a traditional HDD.

In hosting, this means faster-loading websites, shorter response times, and a better visitor experience. That’s why Duplika uses SSDs exclusively in all our plans.

HDD hosting remains a deeply established system because it came before SSDs and is much more affordable. But each generation of SSDs far outperforms the previous one, and the gap between the two technologies is now barely comparable.

You can immediately recognize a mechanical HDD in a desktop computer because it makes noise when reading or writing data: a faint mechanical rumble, as if tiny grains of rice were clattering together. An SSD is silent.

HDD hosting represents the traditional storage system. Its main advantage is still its low cost, making it an affordable option for those who prioritize budget over performance. However, even though modern models have improved rotational speed to boost performance, HDD technology faces an insurmountable physical limit: because it relies on moving mechanical parts—such as motors and read/write heads—it can’t compete with current SSD systems in speed or durability.

The relatively new SSD hosting is as different from HDD hosting as night is from day: SSDs use “solid-state” drives—circuit boards with no motors or spinning disks. There are no moving parts in an SSD; everything works like a large electronic memory. As a result, SSDs make no noise, benefit from a longer lifespan, and—just as importantly—can access multiple files at the same time, much like RAM.

For practical purposes, the difference between HDD and SSD is comparable to this:

→ With an HDD, to make a sandwich, you have to get up from the couch and walk to the kitchen, open the fridge, and find the ingredients one by one.
→ With an SSD, in a second we fly to the fridge, grab all the ingredients at the same time, and have a sandwich ready in 10% of the time it took in the previous example.
That’s how different these two technologies are.

Of course, this evolutionary leap comes at a cost. On average, storing the same amount of information on an SSD costs twice as much per megabyte of space as on an HDD.
That’s why most hosting providers still don’t offer solid-state drives in their plans. Duplika, on the other hand, uses SSDs exclusively across all its services.

Types of hosting

There are different types of hosting services, so the right choice depends on the features and needs of your project.

Shared hosting

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

In these environments, it’s essential for the provider to use technologies such as CloudLinux (as we do). CloudLinux isolates each account so that an issue with one account—including infections—doesn’t affect the other sites on the server.

Multi-account / Reseller plans

Reseller hosting plans let you create and manage multiple independent hosting accounts from a single platform. They’re especially useful for agencies, developers, and professionals who manage websites 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 cloud hosting, here the entire physical server is reserved exclusively for the customer, with no virtualization layer. It’s the most powerful and customizable option, designed for large-scale projects or those with very specific technical needs.

What is “WordPress hosting”?

WordPress hosting was created 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 optimized specifically for websites built with WordPress. This means providing enough memory, processing power, and connectivity, along with a software platform configured to help the site perform with maximum speed, security, and responsiveness.

What should you consider when choosing a hosting service?

Before signing up for hosting, pay special 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 arises.

Backups: check how they’re made and how long they’re kept.

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

Scalability: you should be able to add resources or change plans without having to rebuild your entire site.

Transparency: check the limits, renewal price, and included resources before signing up.
