  3. Cloud Storage Services Introduction

  4. Cloud Storage Services • Cloud Storage Services are public infrastructure for storage of large objects • Files / blobs / images / videos / etc. • Stored in Internet (in a public cloud) • Accessible through some API (REST / SDK / etc.) • May have front-end for end-user access • Could support access control list (ACL) • Could be free (with limits) or paid (on-demand) • Could support CDN delivery or not

  5. Cloud Storage Services – Examples • Amazon S3 • Google AppEngine Blobstore • Google Cloud Storage • Azure Blobs • Rackspace Cloud Files • Google Drive, Microsoft SkyDrive, Apple iCloud • Dropbox, Box.com, ADrive, Mozy, FlipDrive, SpiderOak, SugarSync

  6. Amazon S3 S3 == Simple Storage Service

  7. Amazon S3 • Amazon S3 == Simple Storage Service • On-demand file storage in the AWS cloud • Highly-reliable (99.999999999% durability and 99.99% availability) • Many APIs: RESTful / SOAP / C# / Java / others • Two modes: • Normal – more reliable, more expensive • Reduced redundancy – cheaper, but less reliable • Multiple locations: US, Europe, Asia
