Insights
BB2, a startup financial firm based in London, had built a new digital bank on AWS using cloud-native technology, real-time streaming data feeds, and serverless components. Creativity and innovation have always been the cornerstone of BB2’s business model, and the bank is keen to reinforce this value through innovative digital and electronic banking services.
The client’s customer base is growing rapidly, generating enormous amounts of data and facing challenges in managing it. Colibri stepped in to help BB2 craft a data lake solution and support them on their cloud journey.
Aligning with the BB2 team’s goals, Colibri engineers designed and built the end solution using Lambda, S3, Athena, AWS Glue, Kinesis, DynamoDB, Amazon CloudWatch, and QuickSight.
Using Terraform as the infrastructure-as-code solution, along with GitLab for CI/CD, the team began by designing and building a strong foundation to form a serverless data lake, creating a safe, secure, and collaborative environment. CI/CD pipelines were developed to run in bespoke, pre-built Docker images for clean configuration and fast deployments.
Lambda functions were used to blend the data via Athena SQL for efficient processing, writing to partitioned tables in Glue and Athena. DynamoDB streams were then enabled to capture changes to source tables in real time, with Lambda functions used to process and blend this data in a cost-effective and scalable fashion. With the initial version deployed, we worked to create a data strategy to ingest data from multiple sources and make it accessible and visible to leadership teams in one place.
QuickSight dashboards were created for every source, supported by CI/CD, built using QuickSight APIs to enable the propagation of QuickSight objects between different environments, ensuring proper QA. The BI solution is entirely self-service, leveraging user management to grant varying permission levels to different user teams. This allows the business to access pre-prepared, clean data as well as design custom reports to be shared within their teams.
With our well-architected serverless data lake solution, the client can now capture all of their telematics and metrics, store them centrally, and structure them in a way that makes them easy to analyse. The flexibility of the infrastructure, allowing components to be swapped at low cost, is helping BB2 plan their scaling operations and make informed decisions about the next steps in their data journey.
The self-service, scalable BI tool means that users with no SQL experience can now build dashboards based on data relevant to their specific role and persona. This enables leadership to focus on growth and product development for the bank, with at-a-glance views of key metrics.
User access to read-only dashboards with custom permissions is helping teams across the organisation make quick and accurate decisions.
