Definition of cloud computing: Cloud computing or computing clouds is an infrastructure where computing power and storage are managed by servers remotes where users connect via a link Internet safe. L ‘computer desktop or laptop, mobile phone, touch pad and other connected objects become access points to perform apps or consult data hosted on servers. The cloud is also characterized by its flexibility, allowing providers to automatically adapt storage capacity and computing power to users ’needs.

For the general public, cloud computing takes the form, in particular, of data storage and sharing services. digital data type Box, Dropbox, Microsoft OneDrive or Apple iCloud where users can store personal content (photos, videos, music, documents, etc.) and access it anywhere in the world from any connected device.

cloud computing services

There are several types of cloud services:

  • IaaS (Infrastruktura as a Service, in English): the operating system and applications are installed by clients on servers to which they connect to work as if it were a conventional computer.
  • PaaS (Platform as a Service, in English): In this mode, the cloud service provider manages the operating system and its tools. The customer can install their own applications as needed.
  • SaaS (Sofware as a Service,in English): applications are provided as turnkey services which users connect through software focused oa Navigator Internet. For the general public, this is an example electronic messaging kind GmailYahoo, Outlook.com or suites office automation such as Office 365 or Google Apps.

What is cloud computing?

Cloud computing or cloud computing consists of outsourcing computer data to remote servers. These services are primarily focused on businesses and official bodies. Customer data is sent via the Internet to remote servers located in secure, video-monitored storage centers with limited access.

The supplier is responsible for keeping the data of its customers in a safe place. Cloud computing is available in several service levels:

IAAS (Infrastructure As A Service): Only hardware infrastructure is outsourced.PAAS (Platform As A Service): Outsourcing involves hardware infrastructure, data and applications.SAAS (Software As A Service): All-inclusive which includes complete outsourcing, commissioning and maintenance. This is the most common formula.

Innovative solutions and technologies such asinternet of thingsThe 5G and the big data rely on cloud computing.

What does cloud computing use?

Cloud computing offers some huge advantages to companies, especially the SaaS mode. It allows them to move their hardware, data and applications to servers in specific spaces (the data centers).

By relying on these tasks with a trusted service provider, they save space in their area (no need to store servers) and time (architecture and data storage are taken care of by the supplier).

Another key feature that makes cloud computing meaningful is that the stored data can be accessed from anywhere by those with permission to access it. A boon in the context of collaborative work.

If your employees are based in Madrid, Beijing, New York and Kinshasa, they can all access gate of your company since their smart phone or their computer, enter their password and view the minutes of your last meeting, share their opinions and leave comments in real time. This great work of cloud computing gate a name: workstation synchronization.

How does cloud computing work?

You subscribe to a formula and sign an outsourcing contract for your IT architecture with a provider of cloud computing solutions (monthly or annual subscription). All of your company’s data is sent to remote servers in a storage center. To access it, you connect to the Internet from your computer or your smartphone (validation needed).

The operation and the services provided vary according to the type of service subscribed (IaaS, PaaS, SaaS). The virtual machines of the supplier that operates in clusters. Some security devices (in particular redundancy mechanisms) make it possible to avoid service interruptions that can lead to data loss.

Dedicating all of these tasks that require IT knowledge to a cloud professional offers companies the opportunity to fully dedicate themselves to their core business while guaranteeing maximum protection of their data and applications. (including messaging).
