Key differences between Cloud Computing and Big Data

Cloud Computing

Cloud Computing is a transformative computing paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the internet. This model allows users and enterprises to use applications without installation and access their personal files on any computer with internet access. It relies on sharing of resources to achieve coherence and economies of scale, akin to a utility (like the electricity grid) over a network. Key characteristics include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Cloud services typically fall into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), offering varying levels of abstraction and management. This flexibility supports a wide range of applications, from web-based email to data analytics and software development, making cloud computing a central element in modern IT infrastructure and digital transformation strategies.

Functions of Cloud Computing:
