Fastest way to
transmit 5MB of
data in 1956

Fast forward 60
years… transmit
100PB of data in 2016

Once upon a time, processors double in
speed every 18 months …
 The “Moore’s Law”
stopped 10 years ago.
 CPU, RAM and disk almost
stopped improving in
speed ever since.
7

Processor speed has been stagnant
 But data is being generated
at ever increasing speed.
 Hardware improvement
cannot keep up with data
generation.
 Multi-threaded systems,
distributed systems are the
must.

Distributed Systems are hard

 transmit
 collect
 store
 compute
Petabyte+ storage on
1000+ compute nodes?

GFS
 Master – slave architecture
 Separation of control plane and
data plane
 Low cost, commodity hardware
 Failures are norm, rather
than exceptions
 Balance availability and network
partition tolerance

MapReduce
 A very simple yet powerful
distributed programming model
 Share-nothing architecture
 Programmability
 Data-locality:
 ship compute to data, rather
than shipping data to compute
 Fault tolerance:
 Intermediate state is stored in
storage.
 Failed tasks can be restarted
easily.

Hadoop
 GFS, MapReduce inspired Hadoop
 Initially developed by Yahoo!
 Released in 2006.
 Used by most large enterprises
 Hadoop 3.0 beta 1!

Open source in infra & platform
20

Why open source?
 It’s free ($$$)
 No vendor lock-in.
 Faster development and faster adoption.
 A new approach to foster collaboration.
 Open source software is becoming the standard.
21

Sell open source software, really?
 Water is free, but bottled water is not.
 Cloudera sells the “bottle”
 Cloudera’s Distribution of Hadoop.
 The integration of software.
 The support and services.
 The management software is
proprietary. The OSS is free of charge.

Takeaway
If you only remember 3 things from this talk:
1.Data is the new Oil
2.Open source is the standard
3.Think big! Remember GFS:
failures are the norm rather
than the exception!
