Web hosting:

Web hosting refers to the service that allows individuals and organizations to make their websites accessible via the World Wide Web. In essence, web hosting providers allocate space on a server that is owned or leased for use by clients, who can then store their website files, data, and other content on that server. When someone types in the domain name of a website into their web browser, the browser sends a request to the server where the website is hosted, and the server then delivers the requested web pages back to the user’s browser.

There are various types of web hosting services available, including:

Shared Hosting:

Multiple websites are hosted on a single server, sharing its resources like CPU, disk space, and memory. It’s a cost-effective option for small websites with moderate traffic.

Virtual Private Server (VPS) Hosting:

This type of hosting involves dividing a physical server into multiple virtual servers, each operating independently with its own operating system and resources. It offers more control and flexibility than shared hosting.

Dedicated Hosting:

In this setup, clients lease an entire physical server dedicated exclusively to their website(s). Dedicated hosting provides the highest level of performance, control, and security but is also the most expensive option.

Cloud Hosting:

Websites are hosted on a network of interconnected virtual and physical cloud servers. Cloud hosting offers scalability, flexibility, and reliability as resources can be dynamically allocated based on demand.

Managed WordPress Hosting:

Hosting specifically optimized for WordPress websites, offering features like automatic updates, enhanced security, and specialized support.

Reseller Hosting:

Users can resell web hosting services to their own clients, often under their own brand, while the actual hosting infrastructure is managed by a third-party provider.

When choosing a web hosting provider, it’s essential to consider factors such as reliability, uptime guarantee, security measures, customer support quality, scalability, pricing, and the specific needs of your website. Different hosting providers offer various packages tailored to different types of websites, ranging from personal blogs to large e-commerce platforms.

Typically, web hosting requires the following:

  • one or more servers to act as the host(s) for the sites; servers may be physical or virtual
  • colocation for the server(s), providing physical space, electricity, and Internet connectivity;
  • Domain Name System configuration to define name(s) for the sites and point them to the hosting server(s);
  • a web server running on the host;
  • for each site hosted on the server:
  • space on the server(s) to hold the files making up the site
    site-specific configuration
  • often, a database;
  • software and credentials allowing the client to access these, enabling them to create, configure, and modify the site;
  • email connectivity allowing the host and site to send email to the client.

Host management:

Host management typically refers to the processes and practices involved in overseeing and maintaining a group of hosts or servers within a networked environment. This includes tasks such as configuration, monitoring, security, and optimization to ensure that hosts are functioning effectively and efficiently.

This involves setting up and maintaining the configuration of hosts, including hardware settings, operating system configurations, and installed software. Hosts need to be monitored for performance metrics such as CPU usage, memory utilization, disk space, network traffic, etc. Monitoring tools are used to keep an eye on these metrics and identify any issues that may arise.

Security:

Because web hosting services host websites belonging to their customers, online security is an important concern. When a customer agrees to use a web hosting service, they are relinquishing control of the security of their site to the company that is hosting the site. The level of security that a web hosting service offers is extremely important to a prospective customer and can be a major factor when considering which provider a customer may choose.

Web hosting servers can be attacked by malicious users in different ways, including uploading malware or malicious code onto a hosted website. These attacks may be done for different reasons, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
