This document discusses total cost of ownership considerations for Hadoop implementations. It outlines different deployment methods like on-premise Hadoop, Hadoop appliances, and Hadoop as a service through cloud providers. For on-premise implementations, it identifies key cost categories and provides a sample TCO calculation over 36 months. It also discusses factors for managing implementation risks from vendors and internal IT. The document concludes by outlining scenarios for when on-premise or Hadoop as a service may be preferable based on organizational needs and IT resources.

2. Part 1 – Estimating TCO

3. Iceberg
Estimating TCO is hard.
Like an iceberg, many
costs are hidden.
Example :
integration of Big Data
within the existing
ecosystem.

4. Hadoop Implementations
Hadoop deployment methods
Sample Vendors
Hortonworks IBM, EMC AWS EMR
Cloudera Oracle, Teradata Rackspace Altiscale
MAPR VMware Gogrid Quoble
On Premise
Hadoop
Appliance

Hosting
Hadoop as a
service
Bare Metal Cloud

5. On-Premise Cost Categories
Cost Group Item
Hardware/Infrastructure Costs Servers , Peripherals, Network

Testing(Performance, Capacity, Security etc.)
Management Costs Hardware & software upgrades , Hardware &
software administration, Legal Cost
Support Costs Support staff, Staff training, Travel, Support
contracts, Overhead labor, High Availability Cost
Disaster Recovery Cost, Ticketing & Trouble
Shooting Cost, Monitoring Cost, Internal Audit Cost

12. Part 2 - Deployment
Considerations

13. On-Premise Implementation – When?
• Well-defined use cases with a demonstrated ROI
• Developed and tuned Hadoop applications
• IT team with experience and bandwidth to
manage/maintain Hadoop and integrated
hardware/software stack - as well as troubleshoot job
problems
• Sufficient # of Nodes to Support:
o Growth in Data Sets
o “Bursty” Nature of Jobs

14. On-Premise Implementation – Company Profile
• Large enterprise with a strategic need for Big Data
Analytics
• Moved from an exploratory stage to enterprise
adoption
• Committed IT resources to support Hadoop
hardware/software stack

15. Hadoop as a Service – The Continuum
• Vendors manage the hardware
• Vendors install hadoop
• Vendors manage hadoop

16. Vendors Manage The Hardware
For Organizations that:
• Want to create a small cluster for a relatively
short period of time, for training and software
development purposes.
• Have a short-term processing need and no
internal capacity to support it.
• Do not have an IT organization that can install,
manage, maintain and operate the Hadoop
hardware/software stack, and can fix “broken”
jobs.

17. Vendors Install Hadoop
For Organizations that:
• Have a short-term need or small-scale Hadoop
requirement.
• Have Hadoop applications that are “bursty.”
• Have an IT organization that can operate the
Hadoop hardware/software stack, can manage
scaling the cluster, and can fix “broken” jobs.
• Do not need to tailor the hardware to their
specific requirements.

18. Vendors Manage Hadoop
For Organizations that:
• Do not have the IT organization that can install,
manage, maintain and operate the Hadoop
hardware/software stack, and fix “broken” jobs.
• Do not have the IT hardware infrastructure that’s
required.
• May need an “always on” Hadoop environment.
• Need service providers that:
• Can handle all aspects of the IT support for Hadoop.
• Can provide comprehensive SLAs.
• May offer hardware optimized for Hadoop.
