Understanding what influences data lakes costs

Across both real-time and batch processing, data flows through different stages. For each stage, there is an option to use managed services from AWS or to use compute, storage, or network services from AWS with third-party or open source software installed on top it.

In the case of managed services, AWS provides service features like high availability, backups, and management of underlying infrastructure at additional cost. In some cases, the managed services are on-demand serverless based solutions, where the customer is charged only when the service is used.

In case of third-party or open source software, the user pays AWS for infrastructure components being used and does the management and administration work themselves (in addition to license cost, if applicable).
