Importance of cloud computing in IT sector

1. Importance of cloud computing in IT sector The cloud architecture generates digital spaces accessible from the Internet and equipped with on- demand computing resources to be rented and paid for based on use (pay-as-you-go).Each “cloud” can be considered a virtual data centre, therefore a space containing the servers, the storage capacity, the databases and various computing tools. A space that can be used simultaneously by several users and that remains “separate” from the local computer: the computation takes place entirely on the “cloud” via the Internet, and no data is saved on the computer or the connected device but a remote server.Meta Business Suite connected to the Internet is enough to access the IT resources needed 24 hours a day. How does cloud computing work? The Meta Business Suite Dashboard can be divided into the front end and back end, the user’s side of the computer and the side of the “cloud”, connected to each other by the Internet. The front end, what the user “sees”, is made up of the computer or network of computers used and the application/interface used to access the cloud. Sometimes, as in the case of e-mail programs, the interface is a simple Internet browser. The back end is instead made up of the actual cloud system: the servers, computers and storage systems that “support” the online service.The architecture of cloud computing is, in fact, generally centralized, with well-defined client-server roles: the computers that connect from the front end are “clients”. They require services from the back-end system that acts as a “server” and provides.Meta Business Suite Ads The Internet connection allows you to access the cloud from any device through the interface, but apart from particular configurations, cloud computing is not a distributed, horizontal, but vertical architecture. The back end can be composed of several remote central servers for each application: the servers manage and order requests through middleware software, which operates between the operating system and applications and make the client and server communicate with each other.

2. Types of cloud computing Private cloud The private cloud is an architecture dedicated to a single user or organization, with complete remote access and a high level of personalization and control of resources.The private cloud can be stored in a dedicated structure, in the local data centre, in the supplier’s data centre or in an external data centre, but the connection/access takes place via a private network (VPN / LAN) to ensure maximum privacy and security. Public cloud The public cloud is an architecture in which all the back end is owned by the provider, who manages and takes responsibility for it. Hardware, software, and infrastructures belong and are the responsibility of the supplier, who rents them to the user/organization through subscriptions/licenses on use.The resources are then shared with Facebook Marketing and made available “on-demand” according to needs. Hybrid cloud A hybrid cloud is a mix of a public and private cloud: it combines the services of the two cloud modes according to the user’s needs.The resources are then moved at any time from the company to the “cloud” and vice versa. Community cloud The community cloud is available to multiple parties with activities or businesses in common: it is generally a private cloud managed by the community with shared access.
