  1. User experience for the customers using the tools
  2. Modernize applications technologies that integrate with the on-premises
  3. Agility and time to market for data products (like voice enabled BI etc.)

Solution Delivered to Meet Challenges

  1. We proposed Multi-tenant shared infrastructure application which ensures data isolation on multiple levels.
  2. We provided single sign-on functionality by integrating SAML based identity providers with AWS Cognito. Additionally, each user has a specific role along with certain permissions.
  3. Provided solution connects with each tenant/organization on-prem network using VPN connectivity through AWS Transit Gateway. Added security was provided by encrypting the traffic between application VPC and on-prem network.
  4. Using AWS Glue JDBC connector application connects with tenant’s on-prem Oracle and MSSQL database along with Rest API. It fetches the data and saves it on S3 in parquet format for further usage. AWS Glue was also used to process data from CSV which is uploaded by the end-user.
  5. Our solution encompass a UI tool that enables non-technical users to join multiple datasets into a new one using columns. Users can also apply filter, sorting, or grouping on the resulting dataset. Additionally the user can preview the resultset before saving it.
