Pythian helps a telco giant reduce its costs in managing today’s explosion of unstructured data

Customer Success

Telco giant reduces costs managing unstructured data 

A telecommunications provider needed to establish best practices for the use of NoSQL and open-source databases that would result in cost savings. Pythian delivered the solution.


As a telecommunications provider with hundreds of millions of customers worldwide, our client has substantial needs in managing its data. Traditionally, the client has been able to rely on Oracle and Microsoft databases. However, today’s data is growing exponentially in volume and is increasingly unstructured. The client recognized that it was time to invest in the performance and cost-effectiveness of non-relational open-source databases. 

Pythian worked with the client to establish NoSQL reference architecture patterns, best practices, and appropriate databases for common use cases. To save the time and money involved in making existing hardware available, Pythian instead recommended Google Cloud Platform as the host for this project. 

What we did

  • Tested the feasibility of replacing Oracle for a specific time-series use case: aggregating billing events to generate invoices at a given cadence (30 to 60 days); to perform the test, Pythian delivered a time-series Cassandra PoC hosted on Google Cloud virtual machine instances
  • Selected Terraform to provision the virtual machines, and Puppet automated the installation of Apache Cassandra
  • Exported client’s billing events from their Oracle database as a CSV file, which was ingested via Apache Spark 

Technologies used

  • Google Cloud Platform
  • Apache Cassandra

Key Outcomes

The volume and complexity of today’s data calls for open-source, non-relational databases that operate in the cloud. Thanks to Pythian and their expertise in data and cloud, we now have a clear strategy for using that technology.
