Study Notes
Cloud Architecture
Design Principles
- Scalability involves designing to scale horizontally by adding more resources or vertically by increasing resource capacity
- Flexibility involves designing to adapt to changing requirements
- Reliability involves designing to withstand failures and minimize downtime
- Performance involves designing to optimize resource utilization and minimize latency
- Security involves designing to protect data and applications
Architecture Patterns
- Monolithic Architecture involves a single, self-contained unit
- Microservices Architecture involves breaking down into smaller, independent services
- Event-Driven Architecture involves services communicating through events and messages
- Serverless Architecture involves focusing on application code, not infrastructure management
Cloud Architecture Best Practices
- Decoupling components involves using APIs, queues, or events to separate components
- Using managed services involves leveraging AWS services for scalability, reliability, and security
- Implementing loose coupling involves minimizing dependencies between components
- Designing for failure involves anticipating and planning for failures in the system
