Big Data Solution Requirements

Classes of Big Data Challenges

• Data that is naturally unstructured and/or rich in structure that require extensions of traditional data management tools

• Ability to create flexible analyses

• Ability to evolve analyses to meet future needs

• High velocity data that is increasingly being used in agile decision making

• Data set sizes that pose significant challenges to traditional data management infrastructure

• Peta Bytes, Zetta Bytes

Complexity

Velocity

Variety

Volume

Big Data Management

Fundamental Improvements

• Structural constraints to performing new analyses

Unconventional Analytics – Prediction & Sentiment Analysis

• Data volumes and velocity exceed processing capacity

Larger Data Volumes (petabytes)

•Relational data infrastructure is constrained in handling Unstructured & Rich Structured data

Analysis of Unstructured Data

• BI Capabilities optimized for traditional BI, not Big Data

Integrate and Leverage Existing BI

• Low cost Data Storage & Management Capacity

• Framework/platform driven high performance allowing creation of on-

demand analytic structures

• Software Managed Recovery & Graceful degradation

• Minimized data movement within the environment

• On-line Component Recovery

• Capture data in raw form and process to meet evolving integration &

analytic needs

• Ability to overcome relational database limitations to handle rich structure

• Data Science discipline helps meet business demands

• Extension of BICC framework to manage Big Data class of problems

Depending upon the enterprise and its requirements, the IT department will need to

develop capabilities and services in one or more of the Solution Stacks. The new

architectures are particularly demanding in a variety of ways:

• Skills Development

• Time to Market

• Disaster Recovery

• Operations and Maintenance

The Big Data Application Development Process

Assessing the Capabilities to Deliver New Analytics Applications

Page 8: The Executive View on Big Data Platform Hosting - Evaluating Hosting Services for Big Data Computing Cloud Expo 2013

Some applications are easily migrated to the cloud and others strain under remote network

conditions, multi-tenancy security risks, virtualization performance overhead, or other cloud

model characteristics. Some of these characteristics are particularly troublesome for big

data solutions, while others are particularly advantageous:

• Performance in the Cloud

• Security in the Cloud

• Data Growth in the Cloud

• Business Continuity in the Cloud

The Big Data Platform Environment

How Does Cloud Delivery Impact Big Data Applications?

• Governance in the Cloud

• Termination of Services in the

Cloud

• Costs & TCO

Depending upon the rigor and maturity of their IT processes, an enterprise may or may not

have the opportunity to formally present their requirements and to evaluate various

platform options. For those teams who are able to do so, they may follow a simple

evaluation process outline:

• State the Prioritized Requirements

• Measure the Options

• Weigh the Options in terms of time, cost, and organization impact

The ultimate choice of a Big Data architecture and its components will be dependent upon

the solution class, the infrastructure site, and the infrastructure platform . These choices

will impact the feasibility, cost, and the success of the Big Data application.
