Amazon Web Services
Amazon Web Services (AWS) is a subsidiary of Amazon that provides scalable, reliable, and inexpensive cloud computing services. AWS was launched in 2006 as a way for developers to build and host applications in the cloud, utilizing Amazon's infrastructure. Here are key points about AWS:
History
- AWS was first announced in a press release in March 2006 with the launch of the Amazon Simple Storage Service (S3), followed by Elastic Compute Cloud (EC2) in August of the same year.
- The service started as an internal project to manage Amazon's own infrastructure needs but was then expanded to offer cloud computing services to the public.
Core Services
- Compute: Services like EC2, which allows users to rent virtual computers on which to run their own computer applications.
- Storage: S3 for object storage, EBS for block storage, and Glacier for archival.
- Databases: Options include RDS, DynamoDB, and Redshift.
- Analytics: Services like Athena, EMR, and Kinesis for big data processing and real-time analytics.
- Machine Learning: SageMaker provides tools for building, training, and deploying machine learning models.
- Security, Identity, & Compliance: Services like IAM (Identity and Access Management) and AWS Shield for protection against DDoS attacks.
Features and Advantages
- Scalability: Users can scale their computing resources up or down as needed, paying only for what they use.
- Flexibility: Offers a wide range of services that can be combined to meet almost any IT need.
- Reliability: AWS infrastructure is designed for high availability, with services like Route 53 for DNS.
- Cost-Effectiveness: Pay-as-you-go model reduces the need for large upfront capital investments in hardware.
- Global Reach: Data centers around the world, enabling companies to deploy applications closer to their users.
Innovations
- AWS Lambda allows running code without provisioning or managing servers, introducing the concept of serverless computing.
- Amazon Alexa and Echo devices use AWS for backend processing.
Community and Ecosystem
