ENERGY TRANSITION IN PROGRESS2

3

● rise of renewable energy sources

● regulation & market demands

● competition & increased costs

● intelligent devices in the home or along the utilities infrastructure (“Internet of Things”)

● two-way flow of information instead of one-way

● increase of consumption

4

1. increasing density brings increasing data quality problems

2. strict regulations for safeguarding user privacy

3. redistribution of economic power and energy demand

4. rising competition between distributed and central

5. innovation outpaces regulation

Big Data Challenges at Google

17

Google's mission to "organize the world’s information" presents new challenges.

18

Big Data technologies invented at Google

2012 20132002 2004 2006 2008 2010

GFS

MapReduce

Bigtable Colossus

Dremel Flume

Millwheel

How do we … ?

20

… build a 100TB+ filesystem?

Need: Google was building enormous data sets, and needed an abstracted way to store and access at scale.

21



Solution: GFS (replaced by higher-scale Colossus in 2010)

22



Solution: GFS (replaced by higher-scale Colossus in 2010)

Google Cloud Storage

23

Need: Massive data index files took weeks to rebuild. We needed random read/write access.

… build a petabyte database?

24


Solution: Bigtable (internal service launched 2006)


25


Solution: Bigtable (internal service launched 2006)

Google Cloud Bigtable


26

Need: Ad hoc queries over massive quantities of data, in just seconds.

… query a trillion rows in seconds?

27


Solution: Dremel


28


Solution: Dremel

Google BigQuery


29

Need: Process petabytes of static and streaming data, quickly.

… build data-processing at Google scale?

Years of engineering to...

Teach Bigtable to configure itself

Isolate performance from “noisy neighbors”

React automatically to new patterns, splitting and balancing

Cloud Bigtable

44

Google has had an internal cloud for over a decade

The same engineering that has made our internal services better makes our Cloud better:

Simpler control planes Multi-tenancy Adapts to large, new patterns
