31. H I G H L I G H T S
Massive scale
No table size limits. Unlimited storage.

32. H I G H L I G H T S
Seamless scale
Live repartitioning. Zero admin.

33. H I G H L I G H T S
Predictable performance
Provisioned throughput

34. H I G H L I G H T S
Durable and available
Consistent, disk-only writes

35. H I G H L I G H T S
Zero administration

36. What is provisioned
throughput?

37. Reserve required IOPS
Per table. Set at creation. Scale via API.

38. “ProvisionedThroughput”:
{ “ReadsPerSecond” : 500 },
{ “WritesPerSecond” : 1000 }

39. Scale at any time
No downtime

40. Pay for throughput

41. Per 1kb item:
$0.01 per hour for every 10 writes/second
$0.01 per hour for every 50 strongly
consistent reads/second

42. Per 1kb item:
$0.28 per million writes
$0.056 per million strongly consistent reads

43. Pay for storage
$1.00 per Gb per month of indexed storage

44. Data model

46. “ImageID” = “1”
“Date” =
“20100915”
“Title” = “flower”
“Tags” = “flower”,
“jasmine”, “white”

47. “ImageID” = “1” “ImageID” =”2” “ImageID” =”3”
“Date” = “Date” = “Date” =
“20100915” “20100916” “20100917”
“Title” = “flower” “Title” = “ferrari” “Title” = “coffee”
“Tags” = “flower”, “Tags” = “car”, “Tags” = “drink”,
“jasmine”, “white” “italian” “delicious”

48. Primary key

49. Composite key

53. Simple API
Only 12 operations.
Atomic increment/decrement on number attributes.

54. Automatic scaling

60. Consistency
Writes are always consistent.
Reads are consistent or eventually consistent.

61. Durability
Writes occur to disk, not memory.
Writes are acknowledged once they have been
made in two physical data centres.

62. Availability
Region specific (not AZ)
Continuously replicated across multiple AZs

63. Considerations
Limited index and query model
Throughput is provisioned in 1K operations
Maximum 64K item size
Backup and restore via Elastic MapReduce

64. Databases
Relational “NoSQL”
databases databases

65. SimpleDB
Zero maintenance, NoSQL datastore

66. Flexible queries
10Gb / 1 billion No native
attributes per tabel data sharding
SimpleDB
Zero maintenance, NoSQL datastore

67. Choose the right tool
for the job

68. DynamoDB free tier
5 writes/second
10 consistent reads/second
100Mb storage
