Hands On AWS - Massively Scalable Image Hosting Using S3 and CloudFront - Part 1

Mobycast

In this episode, we cover the following topics:

• A common feature for web apps is image upload. And we all know the "best practices" for how to build this feature. But getting it right can be tricky.
• We start off by discussing the problem space, and what we want to solve. A key goal is to have a solution that is massively scalable while being cost-effective.
• We outline the general architecture of the solution, with separate techniques for handling image uploading and downloading.
• We then dive deep into how to handle image uploading, highlighting various techniques for controlling access over who can perform uploads.
• Two common techniques for securing uploads when using AWS are presigned URLs and presigned POSTs. We discuss how each works and when to use one over the other.
• We finish up by putting everything together and detailing the steps involved with uploading an image.
