The Financial Times says it has reduced costs by 80% and the time taken to run a query to just six seconds after deploying Amazon's RedShift service.
The newspaper had been using an on-premise data warehousing system, which was preventing the organisation from leveraging the data that it collected.
"The system was inflexible; it had a limited feature set; it was spread out, making data analytics and warehousing time consuming and complicated for the IT team; and it was slow, and expensive," a spokesperson for the company said.
The FT, owned by Pearson, chose to implement Amazon Web Services' cloud-based data warehousing service, Amazon Redshift, after it became available in 2013.
The service has so far reduced query time from 27 seconds to just six and cost savings of 80%.
"The product provides a fast, fully managed, petabyte-scale data warehousing service that helps enterprise IT departments to automate labour intensive tasks," added the spokesperson.
"Use cases include, but are not limited to, setting up, operating and scaling a data warehouse cluster; capacity provision; cluster back up; as well as the ability to apply patches and upgrades easily."
Pearson's IT budget is expected to hit £231m this year, of which £58m would be allocated to internal development and maintenance, £39m to hardware, £36m to software and £30m to IT services.
