Describe the scope of work in detail. Please include a summary of key deliverables.

Digitalis provided a managed service offering for Apache Cassandra, allowing the Blis engineering team to focus on the core application development rather than the day-to-day maintenance and optimization of the Cassandra infrastructure.
