    • 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

Domain to IP

Posted on by lechuck park

From Claude with some prompting
This image illustrates the process of converting a domain name to an IP address, which is the first step in web service operations. Here’s a breakdown of the image:

  1. Client System Internal Works:
    • Browser (application) Caching: The first level of caching occurs in the web browser.
    • OS Caching: The second level of caching is at the operating system level.
    • /etc/hosts Caching: The third level involves checking the local hosts file.
  2. DNS Service from the Internet:
    • Cache DNS: This is the first point of contact with external DNS services.
    • Root DNS: Manages top-level domains like “.com”.
    • Top Level Domain: Manages specific top-level domains (e.g., “.com”, “.org”).
    • Authoritative DNS: Provides the final, authoritative IP address for the specific domain.

The process follows a hierarchical order:

  1. Check Browser cache
  2. Check OS cache
  3. Check /etc/hosts file
  4. Query Cache DNS server
  5. If not found, Cache DNS queries Root DNS
  6. Then queries Top Level Domain
  7. Finally queries Authoritative DNS to get the IP address

The image also notes:

  • DNS caching uses TTL (Time To Live) for expiration.
  • The system uses a resolve.conf file to get the Cache DNS list.
  • It questions who is managing various levels of DNS (“.com”, “abc.com”, etc.)

This process ensures efficient and hierarchical resolution of domain names to IP addresses, utilizing various caching mechanisms to improve speed and reduce network load.

Web(HTTP) Service Inside

From Claude with some prompting
This image titled “Web Service Inside” illustrates the internal workings of a web service in 8 steps, from the browser to service design:

  1. <Domain> to <IP address>: Converts user-friendly domain names into computer-readable IP addresses. This process utilizes multi-level caching for efficiency and ultimately locates the desired web server.
  2. IP routing: Guides data packets to their destination via optimal paths based on the converted IP address. This ensures accurate and efficient information delivery across the complex network of the internet.
  3. HTTP REQ/RES: Defines the communication rules between clients and servers. It structures how clients make requests and how servers respond, providing a standardized method for exchanging information on the web.
  4. SSL/TLS & HTTP3: Enhances data transmission security and improves performance. It protects information through encryption and enables faster, more efficient communication using the latest protocols.
  5. HTTP Caching & CDN: Increases efficiency for repetitive data requests and delivers content to users faster. This plays a crucial role in reducing server load and improving user experience.
  6. Server Side Works: Involves the actual processing of requests and generation of responses on the server. It covers operating systems, network protocols, and resource management to provide an efficient and stable service foundation.
  7. Service Internal Works: Addresses the internal structure and data processing methods of web services. It covers database management, load balancing, and maintaining high availability to provide reliable service to large-scale user bases.
  8. Service Design: Encompasses the overall architecture and operational strategy of the web service. It involves creating optimal service structures considering user requirements, scalability, and maintainability, as well as establishing continuous improvement and monitoring plans.

Each of these stages is essential in creating a web service that efficiently and securely handles user requests, while building a system that is scalable and easy to maintain at a large scale.
