What is Cloud Hosting & How Does It Work?

More and more companies are migrating their IT infrastructure to cloud technologies. This service promises to replace virtual and dedicated servers over time. Let’s take a look at how cloud hosting works, what are its advantages, and for which projects it is worth using it.

What is Cloud Hosting?

Cloud host is a new type of web hosting that uses multiple servers to distribute loads and resources. Most clouds run on “cluster” technology. That is, the user connects to servers that use the resources of the centralized pool. As a result, even if one system fails, the user is connected to another server.

Using the cloud, you get a part of the cloud cluster. This is a fundamental difference from standard virtual hosting, where you get a certain amount of space on the server.

To put it simply, cloud hosting is a collection of related servers, each of which receives the same load. If one service fails, another is connected to its place, which allows ensuring the continuity of the system.

The cloud has features: for example, the fee is charged for the actually used resources, taking into account the load on the server. The technology also allows you to change the tariff used by increasing or decreasing disk space. This is very convenient for new sites, as well as projects with a periodic load and a pronounced seasonality of demand.

Cloud Hosting Structure

Forming a cloud server is different from setting up a regular web host. It is based on a distributed approach, which implies the distribution of one project over several locations. This is done to prevent the downtime that is common with a centralized approach. Many large sites are moving to this solution, as almost no server can handle huge databases without failures.

When ordering a cloud, a company will need to determine the required size of disk space, software, and applications. You can choose an individual cloud configuration, and, if necessary, change the tariff plan at any time.

Technology Advantages

Speaking about what cloud hosting is, one cannot but mention its advantages in relation to other IT solutions. Among the pluses are noted:

  • Constant availability: You will be able to access the sites 24 hours 7 days a week. In order for the service to fail, all the servers in use must fall, which is almost unrealistic.
  • Safety: Cloud servers are protected against DDoS attacks, and thanks to constant backups, there is no risk of data loss. In the event of an unforeseen situation, you can always recover your lost data.
  • Flexibility: Cloud hosting allows you to choose the optimal configuration of resources depending on your needs.
  • Low cost: You pay only for the resources actually used, so the price in most cases will be more profitable than using a dedicated server.

Comparison with Other Technologies

Let’s see what are the main differences and advantages of a cloud server in comparison with other popular technologies:

Shared Hosting and Cloud: VDS/VPS is a more powerful platform that is suitable for large projects. On such a host, you will be able to install any software and applications, make settings and completely customize the system “for yourself”. Cloud also allows for individual customization, but the possibilities are much less.

Shared hosting is the most affordable option for hosting a website. However, the functionality of such a solution is minimal, so a cloud host is preferable. Of course, Shared is suitable for relatively small projects, but it will not be able to ensure the operation of a large site. At high loads, it shows a significant deterioration in performance.

Dedicated server and Cloud: Physical hardware is more suitable for large projects that require a lot of RAM, disk space, and the use of various software. You can also install your own programs and applications on the cloud, but this solution is more suitable for small and medium sites. However, it is possible to combine dedicated hosting and cloud in the same infrastructure.

What sites is the cloud suitable for?

The types of web projects using cloud solutions are as varied as the resources used by regular web hosting.

Today, the cloud has become actively used for mission-critical web projects. The technology ensures their smooth operation, which avoids downtime and losses. Most often, the solution is chosen for:

  • Internet shops of household and electronic equipment.
  • Corporate websites.
  • Lead generation portals.
  • Projects with high daily traffic.

Cloud hosting is easily scalable, which makes it attractive for information portals. For example, with a sharp jump in attendance, you can always increase the resources used and, conversely, reduce them during downtime.

Ultimately, a cloud solution is a good choice for most projects. In terms of its functionality, the cloud can compete with the shared host and virtual services.

Cloud Hosting and IaaS, PaaS and SaaS

  • IaaS – Infrastructure as a Service – is one of the latest hosting business models. The procedure includes the provision of virtual machines for use through the cloud.
  • SaaS – “software as a service” – a technology for providing an interface using the cloud through an application or a web browser.
  • PaaS — Platform as a Service — is a solution used to deploy an environment for developers. Reduces time-to-market and provides greater flexibility in business processes.

All of these solutions are directly related to cloud hosting, as they use it to deliver their services.

The Future of Cloud Technologies

Cloud resources are becoming more and more important every year for the functioning of the IT infrastructure of various companies. This is due to the high reliability and scalability of the solution; in addition, the use of the cloud is a relatively inexpensive, affordable service. In the future, a scenario is likely in which almost 100% of business processes will move to cloud services.

Overseas, the popularity of the cloud has led most large companies to migrate part of their infrastructure to the cloud.

The position of such technology has not yet sufficiently strengthened, but large corporations have already paid attention to such a service.

Of course, it cannot be said that cloud hosting is a universal solution for any IT infrastructure. When choosing, take into account the pros and cons of the technology, the specifics of the project, the size of the databases, and other factors.
