Study Notes
AWS Architecture Overview
- Cloud Computing Model: AWS follows the Infrastructure as a Service (IaaS) model.
-
Regions & Availability Zones:
- Global infrastructure divided into regions (geographic areas).
- Each region contains multiple availability zones (data centers) for redundancy and low latency.
Core Services
-
Compute Services:
- Amazon EC2: Scalable virtual servers with various instance types.
- AWS Lambda: Serverless computing service that runs code in response to events.
- Amazon ECS/EKS: Container orchestration services for Docker and Kubernetes.
-
Storage Services:
- Amazon S3: Object storage service for data backup, archiving, and analytics.
- Amazon EBS: Block storage for EC2 instances, providing persistent storage.
- Amazon Glacier: Low-cost archival storage for data that is infrequently accessed.
-
Database Services:
- Amazon RDS: Managed relational database service supporting multiple engines (e.g., MySQL, PostgreSQL).
- Amazon DynamoDB: Fully managed NoSQL database service with fast and predictable performance.
- Amazon Redshift: Data warehousing service for big data analytics.
-
Networking Services:
- Amazon VPC: Creates isolated network environments for AWS resources.
- AWS Direct Connect: Dedicated network connection from on-premise to AWS.
- Amazon Route 53: Scalable DNS and domain name registration service.
-
Security & Identity:
- AWS Identity and Access Management (IAM): Manages user access and permissions.
- AWS Key Management Service (KMS): Manages encryption keys for AWS services.
- AWS Shield & WAF: Protection against DDoS attacks and web application threats.
Management & Monitoring
- Amazon CloudWatch: Monitoring service for AWS resources and applications.
- AWS CloudTrail: Logs AWS account activity for governance and compliance.
- AWS Config: Tracks AWS resource configurations and compliance.
Architecture Best Practices
- Scalability: Design systems that can scale horizontally.
- Fault Tolerance: Implement redundancy and failover strategies across availability zones.
- Cost Efficiency: Use reserved instances and spot instances for cost savings.
- Security: Follow the principle of least privilege and regularly audit permissions.
Deployment & Automation
- AWS CloudFormation: Infrastructure as code for deploying resources in a predictable manner.
- AWS Elastic Beanstalk: Platform as a Service (PaaS) for deploying applications without managing infrastructure.
- AWS CodePipeline: Continuous integration and delivery service for automating release pipelines.
Additional Services
- Amazon SageMaker: Machine learning service for building, training, and deploying ML models.
- Amazon API Gateway: Creates, publishes, and maintains APIs at scale.
- AWS IoT Core: Connects Internet of Things (IoT) devices to the cloud.
Summary
- AWS offers a comprehensive suite of cloud services designed for scalability, security, and efficiency.
- Familiarity with core services and best practices is crucial for effective architecture design.
Cloud Computing Model
- AWS operates under the Infrastructure as a Service (IaaS) model, providing flexible computing resources over the internet.
Regions & Availability Zones
- Global infrastructure is divided into multiple geographic regions, each of which contains several availability zones.
- Availability zones consist of individual data centers, ensuring redundancy and minimizing latency.
