Over the last few years, cloud computing has transformed the way businesses operate and manage their IT resources. For novices, the concept can seem daunting. This guide aims to clarify cloud computing by explaining its basic concepts, its benefits and the different types of services available.
What is cloud computing?
Cloud computing refers to the provision of IT services via the Internet, such as storage, databases, networks and software. Microsoft Azure explains that this technology enables companies to access and manage their data remotely, avoiding the need for physical infrastructure on site.
IBM adds that cloud computing allows businesses to benefit from high computing power without investing in major hardware, creating economies of scale and improving efficiency.
Key features of cloud computing
Cloud computing is defined by several key attributes:
- Self-service on demand Access to IT resources without human intervention.
- Wide area network access Accessibility via various devices such as laptops, tablets and smartphones.
- Pooling resources Shared resources serve several users, ensuring scalability and efficiency.
- Rapid elasticity Ability to quickly adjust resources as needed.
- Measured service Automatic control and optimisation of resources via a measurement system.
Advantages of cloud computing
Benefits for businesses include:
- Cost efficiency Reduced hardware, software and maintenance costs. The pay-as-you-go model enables better budget management.
- Scalability Easy adjustment of resources according to demand, ideal for start-ups and companies with variable costs.
- Accessibility Access to data and applications from anywhere, facilitating collaboration and remote working.
- Recovery and backup : Backup and disaster recovery solutions, guaranteeing data security.
Automatic updates Vendor-managed maintenance, enabling companies to concentrate on their core business. Hewlett Packard Enterprise stresses that this helps companies to free themselves from the constraints of IT management.
Types of cloud services
There are three main models of cloud computing:
Infrastructure as a Service (IaaS)
Provides virtualised computing resources. Users can rent servers and storage on demand, with maximum control over the infrastructure.
Platform as a Service (PaaS)
Provides a platform that allows developers to create, deploy and manage applications without worrying about the underlying infrastructure.
Software as a Service (SaaS)
Offers software applications on the Internet, accessible from any device. Examples: Google Workspace, Microsoft 365 and Salesforce.
