Abstraction Suggestions

Summary: use good/established messaging patterns like Enterprise Integration Patterns. Don't make up your own. Don't expose transport implementation details to your application.

Broker

As much as possible, I prefer to hide Rabbit's implementation details from my application. In .Net we have a Broker abstraction that can communicate through a lot of different transports (rabbit just happens to be our preferred one). The broker allows us to expose a very simple API which is basically:

• publish
• request
• start/stop subscription

A quick "how to" on what you need to do to both setup AND recover a single-server PostgreSQL database using WAL-E

• WAL-E: https://github.com/wal-e/wal-e
• Assuming Ubuntu 12.04 LTS ("Precise")
• We'll be using S3. Make sure you have an IAM in a group with GetObject, ListBucket and PutObject on the bucket you want to use (and that it's not public).

Setup:

1. These packages:

getify

var crypto, path, ca, default_cert, certs, file, files, fs, https, httpsServer;

crypto = require("crypto");
path = require("path");
http = require("http");
https = require("https");
http_proxy = require("http-proxy");
fs = require("fs");

files = ["EssentialSSLCA_2.crt", "ComodoUTNSGCCA.crt", "UTNAddTrustSGCCA.crt", "AddTrustExternalCARoot.crt"];
