Quick and dirty database dump to S3 via Node.js

We are implementing database dumping which is straightforward but can be tedious to setup. Here's our setup:

  1. Create AWS user for db backups (e.g. db-backups-{{app}})
    • Save credentials in a secure location
    • If adding db scrubbing, use a separate user (e.g db-scrubs-{{app}})
  2. Create bucket for S3 access logging (e.g. s3-access-log-{{app}})
  3. Create consistently named bucket for db dumps (e.g. db-backups-{{app}})
    • Enable logging to s3-access-log-{{app}} with prefix of db-backups-{{app}}
  4. Add IAM policy for bucket access
  • Select user -> Choose "Add inline policy"

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
