a Multiuser
Apps Platform

3. Apigee
API Management
API Analytics
API Tools

4. Usergrid
Backend-as-a-
Service
& Open Source
Mobile and

5. App, Cloud, & HTTP

6. No Web Stack
Page
Templates
MVC Logic
Database

7. Just Apps and APIs
User Management! Datastore!
Analytics! Location!
Social Graph! Activity Streams!
Messaging!

8. What do we
really want in 2012?

9. /users
/groups
/users/me/followers

10. /restaurants
/products
/car-washes
/<whatever>

11. POST /devices/<id>

12. POST /events
{ “category” : “ads”,
“counters” : {
“ad_clicks” : 5
}
}

13. /users/bieber/friends/s
/users/ed/likes/foods/

14. GET /restaurants?
near=37.803, -
122.404

15. GET /restaurants?
ql=name contains
‘pizza’ and within
5m of 39.962,-
105.114

16. POST
/users/me/activities
{ “title”: “look”,
“location”: …}

17. GET /users/me/feed
[{ “title”: “Ed ate a
slice of pizza”,
“location”: …}]

18. postUserActivity(me,
activity)
[client
postUserActivity:
“me” activity:
activityObj]

19. /token?
grant_type=...
/auth/facebook?
fb_access_token=…

20. /users?
filter=facebook.first_n
eq 'john'

21. /users?ql=name eq
'john' and
facebook.education.
school.name
contains '...'

22. That’s what
Usergrid is.

23. Building a
Push-Button
Platform

24. Not about single
apps
Page
Templates
MVC Logic
Database

25. Not about single
apps
Page
Templates
MVC Logic
Database

26. Lots of Teams...
Team Team Team

27. Lots of Apps...
App App App
Team

28. And App Users...
App
Team

29. And data and
devices
App
Team

30. It’s really hard to
build for this...

31. It’s about seamless
data sharding...

32. and designing for
unpredicable API
traffic...

33. and it’s about doing
a lot of hard stuff so
other people don’t
have to.

34. So, what’s inside?
The usual stuff...

35. JVM
Java
Spring
Jersey
Jackson
Cassandra

36. JVM
Java
Spring
Jersey
Jackson
Cassandra ???

37. Cassandra should
be the only one that
gives you pause

38. What else could I
have used?
MySQL?
Oracle?
MongoDB?

39. Not so hot for this...
App App App App App App
Team Team Team

40. Schema Separate Database Shared Database
Shared
Lame Hmm
Separate
Schema
No Ugh

41. CREATE
DATABASE
ALTER
TABLE

42. Sharding SQL is too
much work.
Oracle is too much
money.

43. Most NoSQL works
at the wrong
abstraction level.

44. So Cassandra...

45. Cassandra sucks.
But you can teach it
great tricks.

46. Everything you hate
about Cassandra
I love

47. Build your own
indexes!

48. Build your own
query system!

49. Build your own
storage format!

50. Build your own
multi-tenancy
strategy!

51. Time to assemble:
2 months

52. Times I’ve regretted
doing this:
0

53. What else sucked?

54. 1. Consistency
2. API Design
3. Permissions
4. Built-In Logic
5. Operations

55. 1. Consistency
ZooKeeper and
Amazon
Whitepapers won’t
save you

56. 2. API Design

57. “Surrender to a
Higher Power
(whatever it might
be)”
All hail Roy Fielding

58. REST drove the
design

59. REST drove the
scalability

60. REST drove the
scalability
Access Model

61. REST drove the
scalability
Access Model
Query Model

62. REST drove the
scalability
Access Model
Query Model
Denormalization Strategy

63. 3. Permissions

64. 3. Permissions
OAuth
Token
Management
Per-request
Overhead

65. 4. Built-in Logic

66. 4. Built-in Logic
Sign-in Flows
Activity Streams
User/Group Management

67. 5. Operations

68. Keep it simple and
elastic
Tomcat
Tomcat
Tomcat
Tomcat
Tomcat Tomcat Tomcat
Cassandra Cluster

69. Running
with it.

70. Projects have
a will of their own

71. Counters

72. Logs

73. Admin UI

75. HyperMedia API

76. Sencha
jQuery
Backbone
PhoneGap
Tiggzi

77. What do we
want in 2013?

78. Take it for granted
and run with it.

79. Use the ideas
Use the code
Use the cloud

80. usergrid.com
git.io/usergrid

81. Mobile Client

82. Mobile Experience

83. API

84. Web Version

85. Building apps in
2005
was very different

86. LAMP
is not multi-tenant

87. LAMP
is not multi-server

88. LAMP
does too little

89. LAMP
does too much

90. Rails, Django, Node
don’t change the
overall architecture

91. NOSQL works at the
wrong abstraction
level.

92. PaaS is still the
same thing
(to some extent)
