Case for Cisco Intercloud Services for Analytics…
 Cisco Security and Compliance requirements
• Workloads that deal with personally identifiable data and Cisco
confidential content cannot be uploaded to AWS. Cisco internal cloud
solution is a better fit.
 Customer journey beyond the enterprise
• Applications are hosted on AWS
• Partner systems hosted on AWS and other cloud providers
Presence in AWS and other cloud services required to support these
scenarios for end-end customer journey insights.
 Data virtualization integrated in the CIS Analytics Stack
• Connect data from multiple clouds and multiple big data platforms
 Integrated visualization toolset

CIS Analytics Platform

CIS Analytics Platform Requirements
Infra Provisioning
Deploy a virtual private cloud (VPC) on CIS with compute, storage and memory requirements comparable to the current
production system.
OpenStack
Icehouse OpenStack with Neutron, Nova, and Swift installed.
Big Data Ecosystem
Cloudera’s Hadoop distribution version CDH 5.1.3., ELK Stack, Apache Kafka and Apache Storm.
Data virtualization & Cloud Integration
Access to data services and data stores via Cisco Data Virtualization
Runtime Services
Foundational PaaS capabilities including SLAs for uptime, performance, latency, data retention, issue escalation and
support priorities, issue resolution, problem management, deployment process, patch management.
API Services
Provide both fine-grained and coarse-grained access to the all service layers of the CIS Analytics Platform. In the hybrid cloud
model it must support interoperability across platform service providers and promote the cloud concepts of extensibility and
flexibility.

AWS to CIS Migration – Success Criteria
 Successful synthesis of customer interaction data
 Successful automation of the end-end data process pipeline
 Build behavioral insight services
 Access to data and services via data discovery and visualization tools
 Meet the performance, scale and platform stability requirements
 Successful deployment of CiscoDV on CIS
 Connect HDFS and Hive DS with CiscoDV via Hive and Impala
 Build and expose insight services for consumption by limited users

PoC: Analytics with Spark on CIS
Existing code
 Made in Ruby with Wukong to run on Hadoop
 A history of changes and modifications
 Script-based, steps communicate via intermediary files
Goal
 Revise, rethink and reimplement with Spark on CIS
 Open for advanced cloud analytics
 Improve maintainability by moving away from aging Ruby on Hadoop

computation

cleansed
 Pre-process log records (‘cleanse’)
 Extract HTTP sessions (‘sessionize’)
 Extract user actions, such as ‘search’, ‘download
patch’, ‘open manual’, ‘open a bug’
Ruby: Scripts with temp files
 Each box on the figure is a script in a separate file
 They pipe Gb of data as input and output
 Random matching of nodes to data for sessionizing
 Lots of redundant shuffling
Ruby Flow
global sort in time
global group by IP

Main
computation

cleansed
 Same flow, but each box is a Java or Scala function
No intermediate temp files
 Steps are chained by Spark, often without any need for
intermediate data
 If still needed, the data is stored in memory and local
disk as much as possible
Local computation
 Cleansing is computed on nodes local to data blocks
(same as Ruby)
 Sessions are built per IP
 On separate nodes each handling a single IP range
 One copied to the node on partition the data remains
local
Spark Flow
global partition by IP
local sort in time

 Volumes
 Logs of a single day: 52 Gb
 Total of 110 mil records
 Where 53 mil records are kept after pre-filtering
 Producing over 1 mil user actions
 Cluster of 30 nodes
 Ruby
 Runtime 140 min
 Spark
 Runtime 7 min (20 times faster )
Runtime comparison

 Extracting sessions means sort in time and group by IP
 Ruby:
 sorting in time and per-IP grouping is performed across the whole cluster (very bad, lots of IO)
 Spark is good at dealing with partitions:
 per-IP groups are placed on different machines (partitions)
 global sort in time is replaced by many local per-IP sorts done on machines responsible for
extracting sessions for specific groups of IP addressed
 Other improvements
 Avoid redundant temp files, redundant (de)-serialization of objects (comes with Java/Scala), stages
keep data in memory when possible (comes with Spark)
 Cache results of user agent resolution that are heavy on regular expressions
Why?

Data Virtualization for Intercloud Analytics
Customer Benefits
 Discover data beyond the enterprise: Virtual integration that combines traditional
enterprise data, Big Data stores on CIS and AWS, cloud data from SaaS providers and,
Cisco Customers and Partners
 Seamless interoperability offers easy access to data across distributed data sources
in the intercloud analytics platform
 Universal data governance maximizes enforcement of data security rules
 Analytics Data Hubs: Deployment flexibility to build hybrid/virtual sandboxes that
enable nimble data discovery and rapid data analytics to support multiple LOBs
 Deliver data to any number of analytics tools.
