What is cloud storage?

Cloud storage means a data storage method where information is kept online through a cloud computing service. The great advantage of this approach is to provide each employee with a reliable tool in order toaccess data anytime, anywhere by simply connecting to an online space.

Promoting teamwork in real time via the corporate document sharing, making it possible to avoid data loss and ensuring optimal data protection, cloud storage combines the benefits.

How do you choose the best cloud services?

To choose the best cloud service, you need to consider 5 criteria:

• The type of service: IAAS (Infrastructure as a Service) is suitable if you need infrastructure (servers, storage, network) and want to manage applications and operating systems yourself. PAAS (Platform as a Service) is ideal for developers who want to focus on development without worrying about the underlying infrastructure. Finally, for end users who need ready-to-use applications, choose SAAS (Software as a Service).
• Cost and pricing : Compare pricing structures (on demand, monthly/annual subscriptions, etc.) and assess hidden or additional costs (storage, data transfers, support)
• Security and compliance: Ensure that the provider meets the security and compliance standards relevant to your industry (ISO, GDPR, HIPAA, etc.). Review options for encrypting data in transit and at rest.
• Scalability and flexibility: Verify the ability of the service to evolve with your needs (adding resources, managing the load) .Make sure that the service can easily integrate with other systems and tools that you use.
• Ease of use: Test the user interface to see if it's intuitive and easy to use. Check to see if the provider offers free trials or demo versions.

How does cloud file storage work?

Cloud file storage makes it possible to group various types of content (text, images, videos) in a dedicated space. Data is protected by private encryption, which ensures its security. For the rest, the main advantage of file storage in the cloud lies in the fact that you can access data anywhere and under any circumstances, while avoiding the risks of data loss.

Cloud file storage works by hosting data on remote servers that can be accessed via the Internet. Here are the key steps in the process:

1. Uploading Files : The user uploads files from their device (computer, smartphone, etc.) to a cloud storage service such as Google Drive, Dropbox or OneDrive.
2. Remote servers : The files are stored on servers managed by the cloud service provider. These servers may be located in data centers around the world.
3. Replication and redundancy : To ensure data security and availability, files are often replicated and stored in several different locations. This protects against data loss due to hardware failures or disasters.
4. Access and Sharing : Users can access their files by logging into their cloud account from any device connected to the Internet. They can also share files with other users by giving them specific access rights.
5. Security and Encryption : Cloud service providers use encryption techniques to protect data in transit (while downloading and downloading) and at rest (when stored on servers).

This storage model offers great flexibility, allows easy and shared access to data, and reduces physical storage requirements on personal devices.
