Serverless Data Lakes on Amazon Web Services (AWS)

Loan Marketplace Harnesses Their Data Using Server-less Data Lakes

WCI Data Solutions was able to help the largest small business loan marketplace in the United States harness their data by designing and developing a serverless data lake service on Amazon Web Services (AWS) with Amazon S3 as the primary storage platform. 


Our customer is the largest small business loan marketplace in the United States. Small business owners utilize their free online service to find financing by browsing multiple loan products from a network of more than 75 lenders. The platform reviews metrics including the business's financial projections, use of funds, industry, and monthly revenue to find the right loan option for borrowers, helping traditionally underserved groups like women and minority-owned small businesses, mom and pop shops, and seasonal businesses. Their matching engine allows small business borrowers the opportunity to comparison shop across a broad range of lenders and loan products, decreasing their time and effort, and optimizing which lenders to send applications to.


Our customer came to us with an interest in the development and deployment of a Data Lake solution on Amazon Web Services. They wanted a system capable of supporting both analysis and reporting across the organization but also designed to accommodate future consumers, query methods, and new data sources. They wanted to begin this development with an internally developed system we’ll refer to as their “CRM”. The CRM application is also deployed in AWS and uses Aurora RDS as a backend. This will be the first data source used by the WCI developed solution, with other sources to follow. The data will be consumed by the organization using both Domo and Power BI.


The engagement required utilizing a broad array of services on AWS, including:

Amazon Elastic Compute Cloud (Amazon EC2), Amazon Relational Database Service (Amazon RDS), Amazon Glue, Amazon Athena, Amazon CloudWatch, Amazon Simple Queue Service (Amazon SQS), AWS Lambda, Amazon Virtual Private Cloud Peering (VPC-Peering), AWS Identity and Access Management (IAM) and Amazon Simple Storage Service (Amazon S3).

WCI assisted the customer in solving this problem by designing and building a serverless data lake service on AWS with Amazon S3 as the primary storage platform. Utilizing an Amazon S3-based data lake architecture allows our customer the means to have a centralized, secure, and highly durable cloud-based storage platform. AWS makes it easy to store data in any format, both securely and at a massive scale with Amazon S3. In an effort to reduce both complexity and cost of development, WCI decided to utilize Amazon Athena as a query service to produce views that could then be used, in conjunction with Domo, to provide valuable business metrics and insights from the CRM data.

With the use of WCI’s solution, our customer now has the ability to scale their data analytics platform as they continue to add data from new sources, regardless of whether it be structured or unstructured data. The new cost-efficient and cloud-based architecture provides business end-users a data analytics process that is both expedient and lends itself to being future proof. Using AWS native services like Athena, Glue and Lambda enables the ability to continue improving data analysis without the burden of maintaining infrastructure or complex ETL processes, and with WCI’s assistance, our customer now has a secured end-to-end framework for their data and analytics practice on AWS.


Our customer now has the ability to harness increased data from various sources and options for future integrations and for use in other business-critical functions. This gives them the capability to analyze their data using different analytics tools and services, which allows them to derive more insights and provide more value for their customers, suppliers, and partners. WCI's developed solution allows them the ability to gain deeper insights into their data in ways that traditional data silos cannot, which in turn helps them continue to support their customers better than any other lending platform.
