Introduction2:37
Explore how a URL shortening service condenses long URLs into shortened links, generating a unique identifier appended to a base URL, with secure, scalable database mappings for fast redirects.
Requirements4:18
Design a reliable and scalable url shortening service that generates unique aliases and supports custom short urls. It provides seamless redirects, analytics, security, rate limiting, and auto scaling.
Use Cases3:23
Design a robust URL shortening service focused on shortening, redirection, analytics, and expiration. Ensure fast, reliable redirects, capture analytics for data driven decisions, and support time-limited links.

Capacity Estimation3:27
Estimate traffic, storage, and data transfer for a URL shortening service by calculating requests per second, URL metadata, and scaling considerations for fault tolerance and high availability.
Data Model3:46
Structure a url shortening database with separate tables for original urls, shortened urls, metadata, and analytics, linking by the shortened url for creation, expiration, and usage data.

Algorithms4:38
Evaluate link shortening algorithm options for system design, including base 62 encoding and hash functions, and propose a hybrid approach to balance length, collisions, and efficiency.
Algorithm Encoding4:18
Explore url shortening algorithms and encoding schemes to design concise, unique, readable urls. Compare base 62, base64, and custom encoding, balancing length, safety, and service needs.
Algorithm Hashing3:39
Explore hashing techniques for url shortening, using md5, sha-1, and sha-256 to generate compact, unique hashes, address collisions with timestamps or unique identifiers, and ensure secure, reliable shortened urls.
Algorithm Hybrid3:45
Design a URL shortening algorithm using SHA-256 hashing and base 62 encoding to generate concise, unique keys, with a database mapping and collision handling via appended identifiers or timestamps.
Algorithm - URL Length4:11
Explore the design trade-offs in url shortening, balancing shorter links with unique combinations using base 62 encoding, and compare six versus eight character lengths and sha 256 or md5 hashing.

Database4:15
Evaluate database choices for a url shortening service, including Cassandra, DynamoDB, and sharded relational databases, focusing on scalability, throughput, and tunable consistency. Weigh data consistency and fault tolerance.
API7:36
Design a clean, intuitive API for a URL shortening service, enabling clients to shorten, expand, and redirect URLs via RESTful endpoints, with authentication, analytics, and error handling.
Architecture3:56
Analyze the current URL shortening service architecture, including the API service, encoding service, and database, and explore drawbacks in hashing-based unique short URL generation and reliable redirection.

Key Generator4:12
Learn offline generation of six-letter url keys stored in a key vault with available and used tables, using transactions to ensure unique, scalable key assignment for url shortening.
Scalability6:13
Explore scaling a URL shortening service by deploying API instances behind a load balancer, applying database sharding and caching, and ensuring high concurrency in key generation with monitoring.
