Cloud computing has become the backbone of modern digital infrastructure. From startups to global enterprises, organizations rely on cloud platforms to store data, run applications, and scale services efficiently. Among the many cloud service providers, Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) dominate the market.
This article provides a detailed comparison of AWS vs Azure vs Google Cloud, helping you understand their strengths, weaknesses, and ideal use cases.
What Is Cloud Computing?
Cloud computing delivers computing resourcesโsuch as servers, storage, databases, networking, software, and analyticsโover the internet. Instead of owning physical hardware, businesses rent resources on a pay-as-you-go basis, enabling flexibility, scalability, and cost efficiency.
Overview of the Big Three Cloud Providers
Amazon Web Services (AWS)
Launched in 2006, AWS is the pioneer and market leader in cloud computing. It offers the most comprehensive set of cloud services with a global infrastructure.
