System Design Concepts: Messaging models
There are two fundamental messaging models in system design: message queues and the publish-subscribe model.
Communication in System Design
Effective communication in system design, plays a pivotal role in ensuring seamless interaction between system components.
System Design Concepts: Consistency Models
Consistency models are essential in managing the complexities of data synchronization across distributed nodes.
System Design Building Blocks: Cache
Cache is used in system design to store frequently accessed data, reducing access time and improving performance.
System Design Building Blocks: Domain Name System (DNS)
A Domain Name System acts like a phone book for the internet. When you type a website's domain name into your browser, your computer contacts a DNS server.
Types of Application Architectures
This article outlines various types of application architectures. Selection is critical for scalability, maintenance, and adaptability.
System Design Building Blocks: Forward and Reverse Proxy
Proxy servers act as mediators for clients and servers, are used for caching and security. They are divided into forward proxy and reverse proxy.
System Design Building Blocks: Blob Store
A blob store is a scalable, flat-structured system ideal for storing unstructured data, better than hierarchical storage in terms of speed.
System Design Building Blocks: Databases
Databases in system design handle storage and retrieval. Relational DBs use tables and schema, while NoSQL offers more flexibility with BASE.
