s3 bucket policy for presigned URLs generated by serverless lambda functions

AWS Presigned URLs

Presigned URLs are useful for fine-grained access control to resources on s3.

For example, if storing larger text blocks than DynamoDB might allow with its 400KB size limits s3 is a useful option.

Ignoring various ACL methods and using presigned URLs, it's possible to create lambda functions that can generate the required upload and download URLs.

Using the default IAM roles and lambda proxy configuration of serverless, lambdas are assigned an IAM role for the application (so that a logical group of functions can share resources - e.g. for a CRUD REST API). Each function then assumes the IAM role via its own function name.

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

serve HLS (HTTP Live Streaming) content from node.js

HLS streaming from node

Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.

loosely based on https://gist.github.com/bnerd/2011232

// loosely based on https://gist.github.com/bnerd/2011232
// requires node.js >= v0.10.0
// assumes that HLS segmenter filename base is 'out'
// and that the HLS playlist and .ts files are in the current directory
