Characteristics of Scalable Architectures on AWS
Scalable architectures on AWS (Amazon Web Services) are designed to handle increasing amounts of work efficiently or to be easily expanded to accommodate growth. These architectures exhibit several key characteristics:
- Elasticity:
- Auto Scaling: Automatically adjusts the number of active servers based on demand. AWS services like EC2 Auto Scaling and AWS Lambda provide this capability.
- Load Balancing: Distributes incoming application traffic across multiple targets, such as EC2 instances. AWS Elastic Load Balancing (ELB) helps achieve high availability by spreading the load.
- Cost Efficiency:
- Pay-as-You-Go: Only pay for the compute power, storage, and other resources used. AWS pricing models (on-demand, reserved instances, and spot instances) help optimize costs.
- Resource Utilization: Efficient use of resources through right-sizing and reserved instance purchasing strategies.
- Resilience and High Availability:
- Redundancy: Deploy resources across multiple Availability Zones (AZs) to ensure high availability and fault tolerance.
- Backup and Recovery: Regular backups and disaster recovery plans using services like Amazon S3, AWS Backup, and Amazon RDS snapshots.
- Scalability:
- Horizontal Scaling: Adding more instances or nodes to handle increased load. Services like Amazon RDS Read Replicas and DynamoDB allow horizontal scaling.
- Vertical Scaling: Increasing the size of an instance or its resources (CPU, memory). This is more limited than horizontal scaling but can be useful in certain scenarios.
- Decoupling:
- Loose Coupling: Designing components so that they can operate independently. AWS services like Amazon SQS (Simple Queue Service) and Amazon SNS (Simple Notification Service) facilitate decoupling.
- Microservices Architecture: Breaking down applications into smaller, independent services that communicate over a network, often using APIs.
