Cloud computing is an internet-based model providing on-demand access to shared pools of configurable computing resources, such as servers, storage, and applications, enabling rapid scaling and flexible resource management.
Cloud computing is a paradigm shift from traditional on-premises IT infrastructure to services delivered over the internet. It encompasses a broad range of services that offer businesses and individuals the ability to use software and hardware managed by third parties at remote locations. Common examples include document collaboration tools like Google Docs and customer relationship management services like Salesforce.
In a network context, the cloud's infrastructure allows for the decentralized placement of data centers, ensuring high availability and disaster recovery. Service models like IaaS, PaaS, and SaaS provide varying degrees of control, from infrastructure management to application development and use. Deployment models such as public, private, hybrid, and multi-cloud address different organizational needs around privacy, compliance, and flexibility.
Advanced networking services within the cloud, such as virtual networks and CDNs, are crucial for creating secure and efficient communication channels. The inherent scalability and elasticity of cloud services ensure that resources can be dynamically adjusted to meet varying workload demands, often with cost models that only charge for actual usage.
The cloud is instrumental in enabling digital transformation by offering a platform that supports the rapid deployment of applications and services, catering to the evolving needs of modern businesses and consumers.
