51. Internet-Scale Application 2007 stats: +20 petabytes of data processed / day by +100K MapReduce jobs 1 petabyte sort took ~6 hours on ~4K servers replicated onto ~48K disks +200 GFS clusters, each at 1-5K nodes, handling +5 petabytes of storage ~40 GB/sec aggregate read/write throughput across the cluster +500 servers for each search query &lt; 500ms Scaling the process: MapReduce: parallel processing framework BigTable: structured hash database Google File System: massively scalable distributed storage

52. Internet-Scale Application 2009 stats: +200B pageviews/month &gt;3.9T feed actions/day +300M active users &gt;1B chat mesgs/day 100M search queries/day &gt;6B minutes spent/day (ranked #2 on Internet) +20B photos, +2B/month growth 600,000 photos served / sec 25TB log data / day processed thru Scribe 120M queries /sec on memcache Scaling the “relational” data: Keeps data normalized, randomly distributed, accessed at high volumes Uses “shared nothing” architecture

54. Service-oriented composition

55. Eventual consistency

57. Federated identity

59. Aware of application lifecycles

61. Logical partitioning

62. Distributed in-memory cache

64. Parallel & distributed processing

65. Asynchronous distributed communication

66. Idempotent (handle duplicity)
