DESCRIPTION
Big Data Visualization Problem in IT Management Serge Mankovski, Research Staff member at CA Technologies January 22nd 2014 Big Data exposes and amplifies need for understanding big picture of what data tells you without loosing track of minute details. This need manifests in different aspects of Big Data from data processing and management to visual analytics and insight. This problem clearly manifests in management of very large IT infrastructures. CA Labs, as a part of CA Technologies, is focusing on the problem of visualization of Big Data in context of traditional IT management problems of root cause analysis, impact analysis, and change management. We will demonstrate examples of the Big Data Visualization problem as we see it and try to somehow outline this area of research problems.

Big Data Visualization in IT Management Environment
Problem as we see it
— Data is more complex than ever before − Three Vs of Big Data − Mushup of structured, semi structured, and unstructured − Longer time frames
— and we are eager to use long term data more than ever before − Big promise of Big Data
— Existing visualization techniques mostly built for less complex data
— Time constraints for interactive visualization remain as before
— It is clear in IT management that new techniques are needed to accomplish common use cases
Problematic Use Cases In IT MGMT
Elements of interest − Single element • Server
• Router
• Database
− Groups • Service • Network • Location
Relationship • Server A hosts Virtual Machine B
• Application A uses Database B
• Service A is contains Application B
3
− Datacenter • Multiple datacenters @ 20,000+ servers each with
several hundred items
− Mainframe • Single LPAR can have 30,000+ items
− Cloud Connected Enterprise • All of the above plus partially transparent cloud
deployments

This problem exists in many places
The Dilemma
5
Access to detail
Reduce screen complexity
6
Our approach to resolving the dilemma
— Common Approach − Show as much as possible − Use various layouts − Use overview and zooming
— Our Approach − Show as little as possible − Use simple layout − Use semantic zooming and
layered overview
Map of IT Environment
— A map of the user’s workspace, where elements of the IT environment are assigned to a layered structure that allows the user to quickly recognize dependencies between areas of the network

Definition of Layers
We define a layer in terms of:
− A set of elements (or aggregations) we want
to visualize on the layer
− The resources these elements share
8
Defining Hierarchical Layers Step 1 – Assign elements to the layer
1. Select subset of elements we want to visualize
2. Assign elements to layer
Services layer

Defining Hierarchical Layers Step 2 – Select related resources
1. Select type of resource dependencies to visualize
2. Select relevant relations between layer element and related resources
Services layer
11
Defining Hierarchical Layers Step 3 – Detect and draw dependencies
1. Identify layer elements with shared resources
2. Draw layer elements to represent overlapping of resources

Getting to What is Important
Start with a complex IT environment
Use simple filters to create an abstract representation of IT
infrastructure
Open areas of interest in context using traditional
visualization tools
