Cloud computing has revolutionized the way technology is used to share information and resources for consistency, relevance, and economies of scale. These three factors are of great importance today when people and companies need to be at the forefront of their activities and achieve profits and income while controlling expenses.
This type of computing is the Internet-based computing method or model that provides on-demand processing capabilities as well as data to computers and other devices on a network through a shared set of resources, such as applications and services, networks, servers. and storage. devices, which can be ordered and used with minimal effort. Cloud computing allows businesses and users to store and process vital data in third-party data centers.
In simple terms, cloud computing means storing and accessing information and applications over the Internet instead of leaving them on local hard drives or internal servers. The information being accessed is not ‘physically close’ and the ‘cloud’ metaphor harkens back to the days of flow charts, graphs and presentations where server infrastructure was depicted as a ‘puffy white cumulus cloud’ storing and distribute information.
Cloud computing or ‘the cloud’ as it is commonly known, allows for a ‘pay as you go model’. The availability of low-cost computers and devices, high-capacity networks, and storage devices, as well as complementary factors such as service-oriented architecture, the adoption of hardware visualization, and utility computing, have all contributed to the success of computing in the cloud in a very important way.
cloud computing architecture
The five specific factors that define cloud computing are:
• Wide network access
• On demand self-service
• Pooling of resources
• Metered service
• Rapid elasticity or expansion
In general terms, that sums up the essence of this type of computing. However, there are several loosely coupled components and subcomponents that are essential for computing to work. These are divided into two sections: the front-end and the back-end that connect to each other through the Internet.
The Front End is the physically visible interfaces that customers encounter when using their web-enabled devices. Not all computer systems use the same interfaces.
The back-end includes all the resources that provide cloud computing services. These are essentially virtual machines, data storage facilities, security mechanisms, etc. which together provide a deployment model and are responsible for providing the ‘cloud’ part of the computing service.
Benefits
Computer science exponents are quick to praise it citing the many advantages and benefits it offers. Among the many benefits, the main ones are:
• Allows you to scale up and down computing needs
• Allows companies to avoid infrastructure costs
• Enables businesses to make applications run faster and faster
• Improves manageability and adjustment of IT resources to meet fluctuating business demands
• Reduce maintenance
The high demand for cloud computing is reinforced by the advantages of cheap service costs, high computing power, higher performance and scalability, and easier accessibility and availability.
