Cloud computing has revolutionized the way technology is used to share information and resources to ensure consistency, relevance and economies of scale. These three factors are extremely important nowadays, when individuals and businesses need to be at the forefront of their operations and to earn profits and revenues while controlling their expenses.
This type of computing is the method or model of computing over the Internet that provides on-demand processing capabilities as well as data to computers and other devices on a network through a shared pool of resources such as applications and devices. services, networks, servers and storage. devices, which can be requested and used with minimal effort. Cloud computing enables businesses and users to store and process critical data in third-party data centers.
In simple terms, cloud computing refers to the storage and access to information and applications on the Internet instead of leaving them on local hard drives or internal servers. The information we have access to is not “physically close” and the “cloud” metaphor refers to the days of charts, graphs and presentations where the server infrastructure was described as a “white and inflated cumulus cloud” that stores and distributes information.
Cloud computing, or “cloud”, as it is commonly called, creates an “à la carte” model. The availability of low-cost computers and peripherals, high-capacity networks, and storage devices, as well as complementary factors such as service-oriented architecture, adoption of hardware visualization, and utility computing have largely contributed to the success of cloud computing.
Cloud computing architecture
The five specific factors that define cloud computing are:
• Broad access to the network
• Self service on demand
• Pooling resources
• Measured service
• fast elasticity or expansion
Basically, it sums up the essence of this type of computing. However, several weakly coupled components and subcomponents are essential for the proper functioning of computing. These are divided into two sections – the front and the back that connect to each other via the Internet.
The front-end server is the physically visible interface that clients encounter when using their web devices. Not all computer systems use the same interfaces.
The backend includes all the resources that provide cloud services. These are essentially virtual machines, data storage facilities, security mechanisms, and so on. which together constitute a deployment model and are responsible for providing the cloud part of the IT department.
Advantages
IT exhibitors are raving about the many benefits and benefits it offers. Among the many advantages, the main ones are:
• Increase and reduce IT needs
• Allows companies to avoid infrastructure costs
• Enables businesses to run their applications faster and faster
• Improves the manageability and adaptability of IT resources to meet the changing demands of the business.
• Reduces maintenance
The strong demand for cloud computing is reinforced by the benefits of lower service costs, higher computing power, higher performance and scalability, and easier access and availability.
