Cloud computing is a technology that allows users to access computing resources such as servers, storage, databases, networking, software, and analytics over the internet. Instead of maintaining physical infrastructure, individuals and businesses can utilize these resources on demand from a cloud service provider.

Organizations that migrate to the public cloud can achieve cost savings of 15% to 50% compared to traditional on-premises infrastructure. Additionally, cloud services provide improved security, increased performance, and greater control over resources, making them an attractive option for many enterprises.

As of 2022, the leading public cloud service providers include Amazon Web Services (AWS) with approximately 32% market share, Microsoft Azure with around 20%, and Google Cloud Platform (GCP) holding about 9%. These providers dominate the market and offer a wide range of cloud-based solutions.
