Cloud hosting

This is a new type of hosting platform that allows customers a powerful, scalable and reliable hosting based on clustered servers with balanced load and billing of public services. A cloud-hosted website can be more reliable than alternatives, since other computers in the cloud can compensate when a single piece of hardware falls. In addition, local power outages or even natural disasters are less problematic for sites hosted in the cloud, since cloud hosting is decentralized. Cloud hosting also allows providers to charge users only for resources consumed by the user, rather than a flat rate for the amount the user expects to use, or an initial fixed-cost hardware investment. Alternatively, the lack of centralization can give users less control over where their data is located, which could be a problem for users with data security or privacy issues.

Cloud computing is the availability on demand of computer system resources, especially data storage and computing power without direct active management by the user. The term is generally used to describe the data centers available to many users over the Internet. Large, predominant clouds today often have functions distributed in multiple locations from central servers if the connection with the user is relatively close, a perimeter server can be designated.

Clouds may be limited to a single organization (business clouds, or be available to many organizations (public cloud).

Cloud computing is based on sharing resources to achieve consistency and reduce scale costs.

Public and hybrid cloud advocates point out that cloud computing allows companies to avoid or minimize initial IT infrastructure costs. Advocates also claim that cloud computing allows companies to run their applications faster, with improved management capacity and less maintenance, and that allows IT teams to adjust resources more quickly to meet fluctuating demand. and unpredictable.

The availability of high-capacity networks, low-cost computers and storage devices, as well as the widespread adoption of hardware virtualization, service-oriented architecture and autonomous computing and public services, have led to the growth in cloud computing. By 2019, Linux was the most widely used operating system, even in Microsoft offers and, therefore, is described as dominant. The cloud service provider (CSP) will examine, keep pace and collect data on firewalls, intrusion identification and / and contrary action frameworks and information flow within the network.
