How did we get here?

Data Mining in the Cloud

Process of extracting structured information from unstructured or semi-structured web data sources

Data Mining in the Cloud

Benefits Good option to handle Big Data You only pay for DM tools he needs Faster deployment and value No maintenance of hardware or software Accessible anywhere and anytime (Web browser) Enables creating analytical sandboxes on demand

to optimize response to sudden market changes Offload expensive processing from overburdened

in house solutions

Data Mining in the Cloud

Challenges Terms of contract with vendors: SLAs and

contingency plans. Regular data transfers from the company to

the cloud over the internet. Security: Companies have no control of

their data beyond their firewalls Dependability on multiple systems:

Vendor’s servers, ISP uptime, etc.
