Full transcript

1. 0:00Google builds and maintains one of the
2. 0:02world's foremost networks of data
3. 0:03centers their design and Engineering
4. 0:05approaches have created a large and
5. 0:06highly scalable data center network over
6. 0:08the next few minutes we're going to get
7. 0:10an exclusive inside look at how Google
8. 0:12works to secure and protect the data
9. 0:13that is stored in their Data Centers
10. 0:16inside of a Google data center there are
11. 0:17thousands upon thousands of machines
12. 0:19carrying out the business of Google and
13. 0:20its customers the machines are
14. 0:22custombuilt by Google to their own
15. 0:23specifications Google builds thousands
16. 0:25of servers every year but all of them
17. 0:27are built exclusively to run in these
18. 0:29data centers only the necessary
19. 0:31operating system services and Hardware
20. 0:32are installed this helps provide a
21. 0:34Computing environment that is much less
22. 0:36prone to
23. 0:38vulnerabilities access to Google data
24. 0:40centers is tightly controlled it's in
25. 0:42Google's policy not to allow Public
26. 0:43tours or site
27. 0:45visits security Personnel are on duty 24
28. 0:47hours a day 7 days a week Google data
29. 0:50centers are watched by a comprehensive
30. 0:52set of video monitoring cameras once
31. 0:54granted access to the facility
32. 0:55authorized personnel must check in at a
33. 0:57reception
34. 0:58area Google takes great measures to
35. 1:00protect his customer's data and the
36. 1:02security and protection of that data is
37. 1:04Paramount Google's customer data is
38. 1:06stored in multiple locations to help
39. 1:07ensure reliability the files that store
40. 1:09the data are given random file names and
41. 1:11are not stored in clear text so they're
42. 1:13not humanly readable for each hard drive
43. 1:15that is received in one of our data
44. 1:16centers Google rigorously Tracks its
45. 1:18location and status when a hard drive
46. 1:20fails or begins to exhibit performance
47. 1:22problems it's brought to this area or
48. 1:24it's reformatted and retested if the
49. 1:25hard drive does not pass these tests
50. 1:27it's removed from the rotation the data
51. 1:29on the hard drive is then overwritten to
52. 1:30help ensure that no customer data
53. 1:32remains on it the data override is then
54. 1:34verified with a complete disre this
55. 1:36process helps ensure that there's no
56. 1:38trace of customer data remaining on the
57. 1:39hard drive for hard drives that have
58. 1:41reached the end of their life Google has
59. 1:42a destruction process that is designed
60. 1:44to further ensure that none of the data
61. 1:45on that drive can ever be accessed the
62. 1:48drives are destroyed in a multi-step
63. 1:49process one device that is used to
64. 1:51destroy old hard drives is known as The
65. 1:53Crusher and is shown here a steel piston
66. 1:55is pushed through the center of the
67. 1:56drive and the platters are deformed
68. 1:58making them unreadable another step in
69. 2:00the process is the drive Shredder shown
70. 2:02here as you can see no one will be
71. 2:04likely to get any of Google's customers
72. 2:05data from these drives after the
73. 2:07crushing process the remains are sent to
74. 2:09recycling centers Google maintains an
75. 2:11extra backup of the data in the data
76. 2:13center that is stored on these tapes
77. 2:14shown here this provides a level of
78. 2:16redundancy to help Safeguard its
79. 2:18customer data Google data centers are
80. 2:20connected to the internet via high-speed
81. 2:22fiber optic cable in each data center
82. 2:25there are multiple redundant connections
83. 2:26to protect against the possibility of a
84. 2:28failure from a single connection
85. 2:31in addition to operating data centers
86. 2:32designed for security and data
87. 2:33protection Google data centers are
88. 2:35designed for sustainability and Energy
89. 2:37Efficiency this is Central to Google's
90. 2:39commitment to being a carbon neutral
91. 2:40company in 2009 Google announced that
92. 2:43its data centers currently met Energy
93. 2:45Efficiency levels that the US
94. 2:46Environmental Protection Agency
95. 2:48projected only the most state-of-the-art
96. 2:49data centers would possibly meet by the
97. 2:51year 2011
