Geocoding

• Given a feed of page view log objects in JSON format with 3 fields:
  • path (string)
  • time (unix timestamp, integer)
  • ip (string)
• Objects show up in a Amazon SQS message queue http://aws.amazon.com/sqs/
• Task: implememnt a service which geolocates the IP address and adds lat and long to the object then sends the new objects to a second queue.

Incoming object:

{page: "/users", time: 1411615161, ip: "12.130.117.132"}

Outgoing object:

{page: "/users", time: 1411615161, ip: "12.130.117.132", lat: 40.3908, long: -74.1116}

Requirements:

• Any technology/language (there is no penalty for using PHP :-) )
• Use 2 SQS queues (one for incoming, one for geolocated data)
• Cache already geolocated IPs for 24 hours
