S3

  • By default all new buckets are private
  • You can have bucket policies and ACLs (ACL can go down to individual objects)
  • Read after write consistency for puts of new objects
  • Eventual consistency for overwrite PUTs and DELETEs
  • Storage classes
    • S3 standard (99.99 availability, 11 9s durability) can sustain loss of 2 facilities concurrently
    • S3-IA lower fee than S3 but you are charged a retrieval fee (99.9% availability)
    • S3 One Zone - IA lower cost option if you don't need multi AZ data resilience (99.5% availability)
  • S3 Intelligent Tiering

👑 Awesome one-liners you might find useful while coding.
// Inspired by https://twitter.com/coderitual/status/1112297299307384833 and https://tapajyoti-bose.medium.com/7-killer-one-liners-in-javascript-33db6798f5bf
// Remove any duplicates from an array of primitives.
const unique = [...new Set(arr)]
// Sleep in async functions. Use: await sleep(2000).
const sleep = (ms) => (new Promise(resolve => setTimeout(resolve, ms)));
// or
const sleep = util.promisify(setTimeout);
