What is Web Hosting – A Comprehensive Guide for Beginners

Web hosting is an essential service that allows you to publish your website or web application on the internet so that people can access it through their web browsers.

When you sign up for web hosting, you are essentially renting space on a physical server owned by the hosting provider to store all the files, databases, code, images, videos, etc. necessary for your website. The web hosting company ensures that your site remains accessible 24/7 and provides the infrastructure required to serve web pages to site visitors.

This comprehensive beginner’s guide will explain what web hosting is, how it works, different types of hosting services available, and what factors to consider when choosing a web hosting provider.

What is Web Hosting and How Does it Work?

Websites and web applications reside on servers – powerful computers that store all the necessary files and data.

When someone types your domain name (e.g. example.com) into the address bar of their browser, it triggers a request that gets routed to the DNS (Domain Name System) server. This server looks up the IP address mapped to your domain name in order to identify the location of the web server hosting your site.

The browser then sends a request to that web server asking for the files that need to be displayed as web pages. The web server locates these files from the server’s storage and transfers them back to the requesting browser, which assembles and displays them visually on the user’s screen.

This quick process is enabled by web hosting providers who offer the web servers, storage, bandwidth, security protections and 24/7 maintenance support required to host the files for a website and deliver them efficiently to site visitors.

In simpler terms:

• Web hosting stores all the website’s critical files on powerful server computers.
• When a user wants to access a website, their browser requests its files from the hosting server.
• The web host then delivers the files from the server to the user’s browser.

Without web hosting, it would not be possible for browsers to retrieve the webpages and display them for users to view and interact with.

Why Do You Need Web Hosting?

There are three main reasons every website owner needs web hosting services:

1. Website Storage

Web hosting provides the storage space necessary to contain all of a website’s elements – HTML documents, images, CSS stylesheets, JavaScript files, databases and more. This storage space resides on the hosting provider’s servers.

Without sufficient server disk space to hold these critical components, it would be impossible for web browsers to assemble the complete website for visitors.

2. Constant Uptime

In order for a website to be accessible on demand, the servers hosting its files need to be powered on and connected to the internet 24/7. If the servers were ever switched off or disconnected, the site would go offline and return 404 errors to visitors.

Web hosting services maintain constant uptime by keeping servers running in climate-controlled data centers with backup power generators. They monitor server performance round-the-clock to respond quickly to any outages.

3. Data Transfer Capacity

When browsers request a website’s files, significant data gets transferred between servers and internet connections. The volume of data that can be transferred reliably is called bandwidth.

Insufficient bandwidth would mean slow page loading speeds and interruptions for visitors trying to use the website. Web hosts supply ample bandwidth and data delivery infrastructure to smoothly satisfy simultaneous requests from many site users.

In summary, every website requires web hosting for server disk space, 24/7 uptime and bandwidth to make it reliably available to website visitors.

Types of Web Hosting

There are several types of hosting services that provide the infrastructure and support needed for hosting websites and web apps. The right hosting solution for you depends primarily on your unique requirements and budget.

Let’s go through the major web hosting options:

Shared Hosting

With shared hosting, a number of websites share space on a single server. It is an affordable, entry-level hosting solution ideal for personal websites and small business sites that do not expect heavy traffic volumes.

The server’s resources – disk space, RAM, CPU cores, and bandwidth, are shared by all accounts hosted on that server. Resources are usually allocated based on the hosting plan purchased.

pros:

• Inexpensive and beginner-friendly.
• Server setup and management handled by hosting provider.
• Allows you to host simple sites without requiring extensive technical expertise.

cons:

• Resources shared with other accounts on server, so activity spikes on other sites affects yours.
• Limited control and flexibility due to inability to customize the shared hosting environment.

VPS Hosting

VPS stands for Virtual Private Server. This type of hosting separates server resources into isolated virtual machines so that each website gets a portion of the resources allocated to it, along with what feels like a dedicated hosting environment.

VPS hosting plans are upgraded versions of shared hosting, suitable for medium-traffic websites with increasing visitors and complexity.

pros:

• Greater control over the virtual hosting environment.
• Dedicated resource allocation prevents activity on other accounts from impacting yours.
• Supports increased traffic and complexity better than shared hosting.

cons:

• Technical expertise needed to configure and customize virtual server.
• More expensive than shared hosting but cheaper than dedicated servers.

Cloud Hosting

With cloud hosting, instead of a single physical server, websites are hosted on a networked cluster of servers that work together as a system.

Websites and hosting accounts are migrated across servers in the cluster to balance performance and redundancy. Cloud hosting is extremely scalable and reliable, ideal even for bandwidth-intensive sites.

pros:

• Highly robust, distributed server infrastructure.
• Easy scalability to handle traffic spikes.
• High uptime due to redundancies across cluster of servers.

cons:

• Most expensive hosting option.
• Limited control compared to VPS and dedicated hosting.

Managed WordPress Hosting

Managed WordPress hosting is a tailored hosting solution optimized specifically for WordPress sites and blogs. It handles hardware capacity, security, caching and backups for WP sites out-of-the-box so you can focus on creating content.

pros:

• Makes managing a WordPress site easy, even without technical skills.
• Preconfigured optimization for top WP performance right off the bat.
• Expert support for WordPress issues from hosting provider.

cons:

• Only useful for WordPress sites, not other platforms.
• More expensive than basic shared hosting.

Dedicated Hosting

With dedicated hosting, you rent an entire server that is exclusively yours to use and configure however you wish. It offers complete control for maximum performance, security and customization.

Dedicated hosting is recommended only for large-scale, high-traffic websites due to the higher cost and complexity associated with managing your own server.

pros:

• Full control over a server and hosting environment.
• No noisy neighbors – resources are completely dedicated.
• Ultimate flexibility for customization and optimization.

cons:

• Most expensive hosting option.
• Requires advanced technical expertise.
• Account owner responsible for server’s upkeep and management.

How to Choose a Web Hosting Provider?

Not all web hosting providers are created equal. The hosting company you choose to host your website has a major impact on its eventual success or failure. Here are the key criteria to evaluate:

1. Reliability and Uptime

A hosting provider needs to offer reliable uptime of at least 99.9%, meaning your website should be accessible online to visitors almost 100% of the time. Anything less results in costly outages and loss of business.

Check reviews and company data to confirm that any web host you consider selecting offers excellent reliability in keeping sites online.

2. Speed and Performance

A fast, responsive website relies on a speedy hosting infrastructure. From server hardware and optimal software configurations to CDN integration for accelerating content delivery, the web host plays a big role.

Evaluate hosts based on the technology stacks they use, performance optimization features and bandwidth capabilities.

3. Security

Your hosting environment needs to be secured against external cyber threats using firewalls, access controls, backups, software patches and robust infrastructure.

Review the security standards, policies and site restoration capabilities before choosing any web host.

4. Technical Support

Even if you manage your own servers, you will inevitably need expert assistance at times from your web hosting provider’s technical team regarding issues like configuration, troubleshooting performance problems, managing DNS settings, etc.

Choose a web host that offers 24/7 customer support via phone, chat and help ticket systems staffed by qualified professionals.

5. Scalability Needs

As your site grows over time, you will likely require more server resources, storage space and data bandwidth from web hosting. Check if the host supports scaling vertically or upgrading hosting plans to meet higher needs down the road.

6. Budget Considerations

Carefully weigh the proposed value versus the monthly, annual or multi-year pricing terms offered across shortlisted web hosting providers. Factor in possibilities of renewals, upgrades and additional services over long timeframes.

A deal may not necessarily be the cheapest upfront but the greatest value over several years. Strike the right balance for your financial plan.

Use these 6 criteria – uptime, speed, security, support, scalability and budget – for evaluating multiple web hosting candidates before making a well-informed decision backed by facts.

Web Hosting vs Domain Registration

Web hosting and domain name registration are two essential aspects of creating an online presence. While they sound similar, their functions are quite distinct from one another.

Web Hosting

Web hosting, as described in detail earlier, stores and delivers all the files necessary to launch a website via browsers. It handles the storage space, servers, bandwidth and maintenance involved with hosting the files that comprise a website.

Without web hosting, the files that make up web pages would not be accessible to send to browsers requesting them.

Domain Names

A domain name is the human-readable address used to uniquely identify a website, like “example.com”. It points to the web host’s servers where the site’s files are stored.

Domain registration involves paying an annual fee to reserve exclusive rights to use that domain online for the duration of the term. This allows you to link your chosen domain name to your hosting account.

Think of the domain as the address that directs site visitors to the right building, while hosting stores the contents of what’s inside that location.

Many web hosting companies allow you register domain names during signup itself, but domains can also be purchased separately then pointed to host servers.

FAQs about Web Hosting

Q: Is web hosting necessary?

Yes, every single website requires web hosting in order to be visible online to the world. Without paying for hosting services to store and deliver your site’s critical files, browsers would not be able access it over the internet.

Q: Can I host my website for free?

Some providers offer extremely limited free web hosting, but this comes at a steep cost in performance, features and customizations. Free hosting is fickle and includes disruptive placements of provider ads or branding on your site.

For anything beyond basic personal sites, reliable paid hosting is strongly advised instead of free services. The small investment is well worth it.

Q: How much does website hosting cost?

Hosting costs can range from less than $5 a month for shared hosting supporting simple blogs and brochure sites, to over $100 monthly for dedicated hosting to run high-traffic ecommerce stores and web apps.

Managed WordPress hosting and VPS solutions fall somewhere in between, depending on configuration and features.

Cost depends chiefly on:

• Hosting type – Shared, VPS, Dedicated etc.
• Technical specs – Processing cores, RAM, storage capacity.
• Bandwidth limits
• Duration of plan – Monthly, annual or multi-year commitments.
• Support and security features.
• Value-added services – CDNs, backups, caching.

Evaluate these variables against providers to land the best hosting value for your needs and budget.
