AWS dominates the cloud space for several reasons — it’s been around the longest, offers the most services (over 200!), and has an unmatched global presence. Their infrastructure is rock-solid, and they’re constantly innovating with new tools like SageMaker for AI and ECS for container management. Another big reason is trust — top companies like Netflix, Airbnb, and Spotify rely on AWS daily. Plus, AWS gives users flexible pricing, strong security, and the ability to scale instantly. It’s not just about technology — it’s the ecosystem of developers, learning resources, and community support that keeps AWS ahead of the competition.
