… but enterprises are now facing it too … but
• Retail and web transaction data (to refine
enterprises are
recommendations, detect trends etc.) also facing it
• “Sensor” data: now
• GPS in mobile phones
• RFIDs
• NFC
• SmartMeters
• Etc.
• Log file monitoring and analysis
• Security monitoring

Utilities deploying smart meters?

4 V’s of Big Data

Defining Big Data

Volume: large
Velocity: high
Variety: complex

Value: variable signal-noise

Storage was the obvious problem
but Analysis is the important one

Storage is the first obvious “Big Data Is Not the
Created Content, nor Is
problem. It Even Its Consumption
Analysis is next. — It Is the Analysis of
All the Data
Surrounding or Swirling
Around It “

Emergence of Hadoop
To address Big Data challenges – storage and processing

 licensed under the Apache v2 license
 created by Doug Cutting and Michael J. Cafarella
 Based on papers by Google from 2004 (MapReduce and GFS)
 Key advances around distributed processing and distributed storage
 First Apache release: 2007
 Yahoo! Contributed all its code in 2009
 Current release (May. 2012): 1.0.3


Hadoop: commercial offering rapidly ramping

What does SOA have to do
with Big Data?


SOA Deployments Generate Big Data

 Big Data is not just in Social Networks or Science Projects
 SOA infrastructures are (quietly) handling increasingly
massive amount of transactions
 Transactions contain key business information:
purchases, inventory levels, package tracking information,
profile updates, etc.
 Multi-tenancy, private and public clouds are accelerating
data growth


SOA Big Data Example

Logistics Company

 Oracle SOA Suite customer Specific process data captured in star schema
 Millions of BPEL processes/day
for analytics

 Transaction systems involved
 analytics limited by a-priori decisions
 duplication of data
 5 terabytes of database
 Purge job every 4 hours


Typical Usage of Datastores by SOA Platforms
Today

XML MTOM

XA • headers
• timestamps
CSV
JSON
XML
• Etc. BLOB

Impact of Big Data:
New Integration Patterns


Pattern 1: Usage of MapReduce data

Async BPEL process
Data Query
 synchronous interaction not an
2. Wait for
option due to Hadoop typical 1. Start Job_done
latencies (minutes to hours) MapReduce job notification

 Getting data is not as simple as a
sync “select” SQL statement
 Split query: start job, wait for 3. Get Data
notification, get data
 Complex to implement for process
developer


Pattern 2: Query data (noSQL or HBase)

Data Query
 Synchronous query against 1. Scheduled
job initiates
NoSQL or HBase
 Getting data from batch-
processed Hadoop output 3. Sync query
of NoSQL
 Not operating on absolute latest
dataset
NoSQL
 Familiar pattern, easy to
2. Result set
implement for process designer loaded into
NoSQL


Pattern 2: Initiate process on data availability

Initiate process
1. Scheduled
 MapReduce job creates dataset job initiates
and drops it on filesystem (ex: 2. Result
set appears
in JSON format) as file in
given
 BPEL process + file adapter location
watches directory for new data
 BPEL process kicks in, parse
JSON and execute 3. File adapter
detects result
set and
initiates new
process


Fast Data
Get Ahead of the Curve


Working with Big Data: some challenges

1. Big data ≠ Infinite storage
Yes, storage is cheap but it helps to have
clean data, with context and less redundancy
2. Hadoop is batch-oriented and there is
inherent latency
"With the paths that go through Hadoop [at
Yahoo!], the latency is about fifteen minutes
[…] it will never be true real-time. " *
Raymie Stata, Yahoo! CTO
(June 2011)

minutes
*: http://www.theregister.co.uk/2011/06/30/yahoo_hadoop_and_realtime/


Get ahead of the curve

Use Event Processing techniques
Filter out,
correlate
1. Filter out noise (ex: data ticks with
no change), add context (by
correlating multiple sources),
increase relevance
2. Identify critical conditions as
you insert data in warehouse
(not after)
Move time-critical analysis
to front of process


Fast Data
Get Ahead of the Curve
Example:
Fast Data Big Data analysis of traffic
patterns and
ms minutes congestion times
for urban planning
Historical

shallow
depth:

Historical depth: deep
Example:
monitoring of traffic
cameras to ensure
given license plate
not in use on
multiple vehicles Add “depth” to your fast data by merging
output of MapReduce to stream processing


How Fast is Fast? DPI
equipment
IP allocation
servers
Fast enough to support explosion of
smartphones in largest markets

 Mobile provider usage <-> IP@ IP@ <-> user

 Billing smartphone data based on usage
 Using OEP to correlate users to packets
through dynamically allocated IP addresses
 Coherence as fast in-memory grid of user
<-> IP addresses
Usage <-> user
 Processes over 800,000 records/s

Conclusion

 Big Data has reached the enterprise
 SOA platforms are evolving to leverage Big Data technology
 Service developers need to understand how to insert and access
data in Hadoop
 Time-critical conditions can be detected as data is inserted in
Hadoop using event processing techniques – Fast Data
 Expect Big Data, Fast Data to become ubiquitous in SOA
environments – much like RDBMS are already
