From Claude with some prompting
focusing on the key technical aspects and operational considerations for designing a web service application.

Web Service [Server Inside] – Design and Operational Considerations

  1. Service Architecture Design: a. Multi-tier structure:
    • Gateway → Load Balancer → API Gateway → DB Proxy → Database
    • Each layer focuses on specific functions, improving maintainability and scalability b. Microservice Architecture:
    • Implemented through “Programmatic Control” at the API Gateway
    • Ensures service independence, increases development and deployment flexibility
  2. Scalability Design: a. Auto Scaling:
    • Applied at each layer (Load Balancer, API Gateway, DB Proxy)
    • Automatic resource adjustment based on traffic fluctuations for improved stability b. Resource Pooling:
    • “Protecting SVC” functionality for efficient resource management c. Load Balancing:
    • Gateway provides “Route with Load Balancing (2 More Resources)” functionality
  3. Performance Optimization: a. Static/Dynamic Data Separation:
    • Static Data Control: HTML/CSS/JS/IMAGES
    • Utilization of CDN services or On-Premise storage b. Database Optimization:
    • SQL, NoSQL, Hybrid options available
    • Connection management through DB Proxy for database load distribution
  4. Security Design: a. Multi-layered Security:
    • Authentication (OAuth2, etc.)
    • Encryption (SSL/TLS)
    • Firewall/WAF/IPS/IDS b. Request Limiting:
    • “Limiting Requests (Protect Domain Service)” at Gateway for DDoS protection
  5. Monitoring and Analysis: a. Comprehensive Monitoring:
    • Collection of Network, Server, and Application Metrics b. Analysis and Planning:
    • Maintenance & Scaling
    • Service Design Upgrade
    • Resource & Cost Optimization
  6. Error Handling:
    • Specification of 400, 500 series errors (Network Error, Service Unavailable, Server Internal, etc.)
    • Emphasis on Gateway-related errors (502 Bad Gateway, 504 Gateway Timeout)
  7. Network and Protocol:
    • “Protocol Converting” functionality provided at the Gateway
    • Separate management of Network Domain Control
  8. Operational Efficiency:
    • Automation: Minimized manual intervention through Auto Scaling, resource pooling, etc.
    • Flexibility: Possible combination of On-Premise and CDN services
    • Cost Optimization: Efficient resource usage, continuous analysis and improvement

Key Advantages of This Configuration:

  1. High Availability and Stability: Stable service provision through multiple layers and auto-scaling
  2. Excellent Scalability: Flexible response to traffic fluctuations
  3. Strong Security: Multi-layered security structure to address various threats
  4. Efficient Resource Management: Cost efficiency through automation and optimization
  5. Flexible Service Development and Deployment: Utilization of microservice architecture
  6. Comprehensive Monitoring and Analysis: Enables continuous service improvement

This design incorporates almost all essential elements required for modern, large-scale web services, enabling stable and scalable service operations. It reflects a thorough consideration of both technical and operational aspects, providing a robust foundation for complex web applications.

Facilities Data Collection Cases

Posted on by lechuck park

From DALL-E with some prompting
The image presents different data collection configurations in facility management systems:

  1. Direct Connection: Equipment directly sends data to the network without any intermediate device.
  2. Controller: Data is collected via a PLC (Programmable Logic Controller), DDC (Direct Digital Control), or Gateway from the equipment and then sent to the network.
  3. Dedicated Meter: Specialized meters are used to collect specific data, which is then transferred directly to the network.
  4. Dedicated Meter & Controller: A setup where dedicated meters work in conjunction with a PLC/DDC/Gateway for data collection and subsequent control before networking.
  5. Internal Control System: An integrated control system manages and monitors data internally before it connects to the network.
  6. Solution System: a Standalone system that is self-contained with full functionalities for a specific operation.

This depiction emphasizes the progression from direct data routing to more complex systems involving multiple stages of data handling and integration.
