What is Amazon Web Services (AWS)?

Amazon Web Services (AWS) is a leading public cloud platform by Amazon that provides IaaS, PaaS, and SaaS services under a pay-as-you-go model (consumption-based pricing). It supports application hosting, data storage, distributed systems, and AI workloads.

Key AWS services include virtual machines (EC2), object storage (S3), managed databases (RDS, DynamoDB), containers (EKS), analytics, and machine learning (SageMaker, Bedrock). The global infrastructure spans 39 geographic regions and 123 availability zones, offering automatic scaling, load balancing, and geo-redundancy for resilience. AWS ensures high availability through IAM (identity and access management), data encryption (at rest and in transit), auditing, monitoring, and multi-layered security. The platform is a leader in supporting enterprise-grade, high-load, and globally distributed internet services.
