Deployment

  Started out with Amazon EC2  A little too early – very Beta back then

  Then S3  Much better – very stable

  Back to EC2 when it stabilised  Been very solid for some time now…

LocalSocial / Dial2Do

Motivations

  Ease of use / Speed of use   Experimentation   AMIs   Flexibility   Pricing

LocalSocial

  S3   Stores AMIs   Fedora 8 from AWS   Plus all our own stuff (RoR, Scripts, …)

  EC2   One “small instance” Server

  1.7 GB of memory, 1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit), 160 GB of instance storage, 32-bit platform

  Runs our AMI fulltime   Two domains right now

  gigmonkey.com   mylocalsocial.com

  And our VPN   EBS

  Connected to running EC2 Instance   Persistent Store for all mySQL DBs

LocalSocial

Heroku

Open Source

  A few words on it   Incredible in terms of potential for re-use, time

saving, cost saving, quality   Must have eyes fully open   License, support, TCOO   Need a house style / approach   Awareness of license types / styles   BlackDuck

Observations

  Great time (imho) for software development   Development and Deployment Tools   Costs   Re-use   Help   Routes to Markets   Speed / gratification (or failure)   Ability to test features, product quickly
