    • Real World Example : PutPlace
      Launched in 2008
      Fully hosted in Amazon AWS
      Ported from Dedicated Hosting
      Full Break down of all Costs
      This is real data– Warts and All

    • Architecture

      3
    • Core Services
      S3 : Storage
      Blob Storage
      Read and write up to 5GB files
      Rest API/SOAP API
      POSIX semantics via EBS
      EC2 : Compute
      Virtual Instances
      Several Sizes
      Local storage is volatile
      Reserved Instances

    • Core Costs
      Resources
      Running Compute instances
      Stored Data
      Bandwidth
      Data in and out of Amazon
      Data between different Amazon regions
      Transactions
      Reads and Writes to S3

    • Compute Costs 2010 (USD)

    • Storage Costs
      $0.15 per GB Month in 2008
      $0.14 per GB Month in 2010
      $0.055 per GB for 5PB or more

    • Bandwidth Costs 2008
      Data In : $0.10 per GB
      Data Out : $0.15 per GB

    • Transactions 2008
      Writes : $0.01 per 1000 requests
      Reads : $0.01 per 10,000 requests
      Note : Only to S3

    • Cost Break Down

    • Dedicated Hosting Costs
      Co-Located Servers
      $16,000 (including local disk + B/W)
      But:
      Long lead times for additional servers
      1 year leases
      No durable storage

    • What would I do Today
      Same architecture
      Use a POSIX distributed file system on nodes
      Start will less redundancy
      Work will more smaller instances
      Look at Google App Engine for Web Pages/API
      Use MySQL rather than Postgres
      Worry less about scaling

    • What you should learn
      The mantra
      Compute
      Storage
      Bandwidth
      Transactions
      Know your costs, check your bills
      Code errors will now cost real money
