# Solution Structure
<a name="solution-structure"></a>

MDAA is a comprehensive solution built using a modular approach. Think of it as a sophisticated building kit for creating secure and scalable data infrastructure on AWS. Just as a building needs a foundation, walls, and utilities, MDAA provides all the necessary components to build your data/AI platform.

## The Module Concept
<a name="the-module-concept"></a>

Think of modules as specialized building blocks. For example:
+ If you want to deploy raw and transformation buckets for your data lake, there’s a datalake module that creates encrypted S3 buckets with proper access controls, sets up fine-grained lifecycle policies for cost optimization and configures bucket policies and cross-account access if needed
+ If you need to query data using Amazon Athena, there’s a module that sets up Athena workgroups with resource controls, configures query result locations, connects with your datalake and establishes necessary IAM permissions for query execution
+ If you want to add AWS Lake Formation settings to your tables, there’s a module that configures Lake Formation permissions and security settings, sets up database and table-level access controls, etc.

## How Modules Work Together
<a name="how-modules-work-together"></a>

Consider this practical scenario: You want to build a secure data lake for financial data.
+ Start with the roles module to create necessary IAM roles and policies
+ Add the datalake module to create encrypted storage
+ Add the Glue module to catalog your data
+ Implement Lake Formation module for compliance
+ Configure Athena module for analysts to query
+ Add audit modules for security
