What is cloud hosting and why use it

-

Cloud hosting is the hottest trend in today’s web hosting world. This is a service that uses multiple servers in order to find load balance and availability optimization. You therefore have access to your website and applications through cloud resources that adapt to your needs. Indeed, you benefit from greater scalability and flexibility with hosting your site on a network of servers instead of a single local server. However, it is advisable to call on an expert in server outsourcing to ensure the proper functioning of this system. With cloud hosting, solutions can be controlled and automated through software, a web portal or a mobile application. The main advantages of this hosting service therefore include a greater emphasis on availability, information saved without risk of loss and ease of scaling with a dedicated IP address as well.

Choosing the architecture of your information system is an essential decision that depends on several issues, such as your budget, your internal expertise and your ambitions. It is also obvious that you are constantly adapting to the various technological developments.
In the case of cloud hosting, the centralized approach is used in a large majority of servers. It consists in associating several websites to a server. On the other hand, in such a system, if this server goes down, all the accounts it contains will also be inaccessible. This problem is often solved thanks to the distributed approach, which consists in distributing the resources on different locations or even several machines. In such a situation, your system will still be functional even if one of the servers is down. Social networking sites and search engines opt for this type of approach.

Cloud hosting is becoming more and more suitable. This technology offers many industries and companies the use of the power and storage capacity of several external servers. In an SME, the use of cloud hosting makes it possible to protect its data from any attack. In addition, this data remains available and easily accessible for all staff at all times. Choosing the cloud also reduces costs and increases agility. In particular, the Microsoft Azure solution offers great flexibility thanks to its hybrid nature.

Cloud hosting today offers three models of hosted services that adapt to different needs.

IaaS (Infrastructure as a service): This is the IT outsourcing of your hardware infrastructure. This service consists of supporting networks, file servers and the storage of your data by the supplier, without you needing to tie them to physical equipment. However, you manage your operating system, data and applications yourself.
PaaS (Platform as a service): This involves outsourcing your hardware infrastructure, data and applications. Indeed, in addition to the IaaS services, the provider offers you third-party software that automatically manages all the tools integrated into your site, such as the web server, the operating system and the database. This allows you greater flexibility.
SaaS (Software as a service): This is the formula that includes all services through a monthly subscription. Appreciated by the general public, your SaaS supplier installs, configures and puts your interface into service. He then takes care of any type of maintenance necessary in the event of a malfunction of your platform.
