Study Notes
Architectural Patterns and Their Suitability
- Independent Deployment: Microservices architecture supports independent deployment, enabling teams to develop, deploy, and scale services individually.
- Monolithic Architecture: Characterized by a single executable where all components are interconnected, making scaling and modifications challenging.
MVC Pattern Benefits
- Primary Advantage: Separation of concerns in the Model-View-Controller (MVC) pattern enhances organization by clearly defining roles for each component.
Pipe-and-Filter Pattern
- Data Processing: The Pipe-and-Filter architecture divides a system into independent filters that process data sequentially, improving modularity and maintainability.
Monolithic Architecture Disadvantages
- Scaling Challenges: As a system scales, a monolithic architecture can become difficult to test and manage due to tightly coupled components.
Decoupled Communication
- Asynchronous Communication: The Publisher-Subscriber pattern facilitates decoupling components through event-driven communication, allowing for more flexible system interactions.
Design Principles
- Modularity: Emphasizes breaking systems into smaller, independent parts to enhance maintainability and scalability.
- Encapsulation: In object-oriented design, encapsulation focuses on hiding internal implementations while promoting reusability.
Service-Oriented Architecture (SOA)
- Core Feature: SOA emphasizes modular design, where services are exposed as APIs, enabling better integration and flexibility.
Architectural Views
- Physical View: Concentrates on the physical deployment of components, including hardware specifics and network configurations.
Shared Data Architecture
- Centralized Data Management: A Shared Data architecture provides centralized data management, simplifying access and consistency of data.
Client-Server Advantages
- Centralized Control: Client-Server architecture offers centralized control, streamlining management and resource allocation in web applications.
Abstraction in Design
- Simplifying Complexity: Abstraction facilitates understanding by focusing on high-level concepts instead of detailed implementations.
Peer-to-Peer Characteristics
- Direct Communication: Peer-to-Peer architecture is defined by direct communication between peers, enhancing resource sharing and redundancy.
Disadvantages of Service-Oriented Architecture
- Increased Complexity: While offering flexibility, SOA can lead to increased system complexity, requiring careful management and orchestration.
Design Considerations
- Scalability Focus: Scalability addresses a system's capability to handle increasing workloads efficiently, ensuring performance remains optimal as demand grows.
Proxies in Distributed Systems
- API Gateway Role: Proxies, such as API Gateways, manage requests between clients and services, enhancing security and load balancing in distributed systems.
Event-Driven Architecture
- Decoupling via Events: Event-Driven Architecture focuses on the decoupling of components through the use of events, allowing for responsive and dynamic interactions.
Database Management Systems (DBMS)
- DBMS Examples: MySQL, PostgreSQL, and MongoDB are recognized as database management systems, while Apache Kafka is not primarily a DBMS.
Challenges in Distributed Systems
- Network Latency: One of the potential challenges in implementing distributed systems includes managing network latency, which can affect performance and reliability.
