Everything you need to Know about Cloud Computing

Cloud computing is among the disruptive technologies that continues to reign the world. The advent of Covid-19 pandemic saw the increased demand for cloud services. Cloud computing gravitates around the storage of programs and data over the internet.

Traditionally, data and programs used to be majorly stored in the computer’s local disk and accessed whenever demanded. But currently technology has taken over for safety reasons and sensitive and important data is no longer stored in the local hard disk.

Cloud computing involves the delivery of on-demand computer services that range from applications to processing and storage over the internet (cloud) and on a pay as you go basis. Cloud service providers, such as Google Cloud, Microsoft Azure and Amazon Web services (AWS) Cloud, rent access to applications, processes and storage.

The benefit of cloud computing is that they reduce the cost and complexity of owning a computing infrastructure or data center, and instead companies pay for what they use and when they use it. Cloud providers, in turn, benefit from significant economies of scale by offering the same services to a variety of clients.

Apart from storage and processing power, other services offered by cloud computing include artificial intelligence (AI) and natural language processing. With cloud computing, services that require users to be closer to the computer hardware resources are availed to them irrespective of their locality.

Examples of Cloud computing is depicted in cloud back-up of photos in smartphones, video streaming services in Netflix and mobile or desktop applications over the internet.

Cloud computing is classified basing on three models: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-Sevice (SaaS).
