CDN Basic Concept and Design – System Design 12

CDN is a group of proxy servers (Proxy Server) placed based on geographical location. Among them, the proxy server is an intermediate server between the client and the server, and the proxy server will also be placed at the network edge (Network Edge). Also because the edge of the network is close to the end user, the placement of the proxy server helps to quickly transmit the corresponding data to the user by reducing delays and saving bandwidth. In addition to serving as simple proxy servers, CDNs can also make them more efficient through some settings and operations.

Key-Value Store key-value data storage explanation – system design 11

Key-Value Store is a Distributed Hash Table, in which DHT is a decentralized storage method that provides hash table-like search and storage. Hash Table is also an Abstract Data Type (ADT). Its advantage is that it can usually complete the Search operation in a relatively fast time.

Data Partitioning What is data partitioning? – System Design 10

Data Partitioning is the process of dividing data in a database into smaller, more manageable sub-blocks. These sub-blocks are called partitions. Data segmentation can be based on a variety of factors, such as time, customer ID, or product category. Why do we need to partition data? For any system that does not scale, the amount of data will continue to grow, and the read and write traffic to the database will continue to increase.

How does Data Replication optimize the database? - System Design 09

Data Replication is an effective method to solve bottlenecks and improve the performance, scalability and availability of the database by replicating data on multiple nodes. This article will introduce the three main models of data replication: master-slave replication (Single-leader replication), multi-leader replication (Multi-leader replication) and point-to-point replication (Leaderless replication), and analyze their advantages and disadvantages.

Introduction to database basics – system design 08

What is a database? A database is an organized collection of structured information or data, usually stored electronically in a computer system. Databases are usually controlled by a database management system (DBMS). The data and DBMS together with its associated applications are called a database system, often referred to simply as a database.
Data in the most common types of databases running today are typically modeled as rows and columns in a series of tables to increase the efficiency of processing and querying of the data. Data can then be easily accessed, managed, modified, updated, controlled and organized. Most databases use Structured Query Language (SQL) to write and query data.

Load Balancer Explained – System Design 07

What is a Load Balancer? The load balancer mainly distributes all user requests to the corresponding servers based on the current server load. The advantage of this is to avoid server overload or crash. However, you can also think about it here. If the traffic of the current system is not high, about only a few thousand requests per second, then a load balancer may not be needed. After all, the more complex a system is, the more things need to be considered.

What is DNS? Introduction to Domain Name System – System Design 06

What is DNS? The Domain Name System (DNS) maps human-readable domain names to machine-readable IP addresses. For example, the corresponding IP for google.com is 142.250.191.78. When a user enters a domain name into the browser, the browser must convert the domain name into an IP address through DNS. Once the required IP address is obtained, the user's request is forwarded to the target server.

Introduction to System Design Components Building Block – System Design 05

System components are the basic building blocks of system design. They can be combined to construct complex software systems. Here we will also review the basic concepts of system design. System design is an important link in software engineering, which involves the overall architecture and design of the software system. A good system design can make software systems more reliable, scalable and easy to maintain.

Of course, if you want to use these components to design a system, you must first understand what design components there are? What does each design element represent? This article will introduce each system component, and the following chapters will explain the details and applications of each component in detail.
