Company Overview

A Central American-based telecommunications company provides fixed and mobile services in 12 countries with commercial operations in Africa and Latin America and corporate offices in Europe and the USA. This particular branch located in Central America works with three other corporate network operators to combine mobile voice, 3G and 4G networks, and cable broadband. The company is one of the leading fixed-mobile operators in the country and has more than 4 million customers on its 4G LTE network.


The company wanted to improve efficiency and conduct more advanced detecting and tracking of cybercrime in its data environment. With large volumes of data being stored and ingested every day, the customer wanted to find a better way to manage and control their data while staying compliant with regulatory requirements. Additionally, the customer wanted to reduce costs across the board, improve data security, and resolve the pain points of their current data supply chain.


Due to their technical expertise and project experience with other branches of the company, Zaloni® became the solution of choice. Using Zaloni®’s DataOps platform, Arena, the customer built an AWS-based data lake to enhance and improve the efficiency of cybercrime detection and tracking applications. With the Arena platform, Call Detail Records (CDR) from the telecom mediation system and customer data from an Oracle on-premises database were ingested into an AWS data lake. Additionally, Arena’s ability to create a transient cluster for EMR allowed for agile, on-demand cloud infrastructure to reduce costs and provide flexibility. This flexibility helped leverage more resources (i.e. compute and storage) on an as-needed basis and provided the much-needed elasticity to process and scale more records.


This branch was the first network provider location within the company to utilize AWS, making tremendous progress in their digital transformation goals and marking the beginning of a new cloud-based environment for their data. With Zaloni®’s Professional Services team leading the project, the Arena platform and its governed DataOps capabilities enabled the customer to process approximately 20 billion records in their data lake. In addition, Arena’s end-to-end capabilities for data migration, management, and governance ultimately ensured regulatory compliance, secured user access, and aggregated high-quality data for reporting.
