Capitolo 14. Progettare un servizio di accorciatori di URL

Abbiamo esplorato il concetto di DNS nel Capitolo 9, notando che è più facile ricordare l'URL di un sito web rispetto ai suoi indirizzi IP, ma che dire degli URL lunghi? È facile ricordare la parte principale dell'URL (ad esempio, learning.oreilly.com in https://learning.oreilly.com/library/view/system-design-on/9781098146887), ma è facile dimenticare l'URL lungo. Spesso inseriamo i link nel testo perché questo aumenta la leggibilità.
Un altro modo per condividere URL lunghi è accorciarli. Ad esempio, LinkedIn accorcia automaticamente qualsiasi URL che fa parte di un post perché ciò contribuisce ad aumentare la leggibilità del post e l'interazione con gli utenti. Nelle applicazioni di microblogging come Twitter (ora noto come X), c'è un limite al numero di caratteri di un singolo post, quindi per ridurre la lunghezza del testo puoi accorciare gli URL tramite un servizio di accorciatori di URL come TinyURL o Bitly e allegarli al post al posto delle versioni complete.
Questo capitolo esplora la progettazione di un servizio di accorciatore di URL e illustra come distribuire il sistema sul cloud AWS. Inizieremo la nostra discussione con la raccolta dei requisiti e le aspettative del sistema. In seguito, entreremo nei dettagli del sistema.
