Department/Project Description
The project has the aim to develop AI Infrastructure (AII) is built atop Amazon Web Services resources with a particular focus on Redshift, SNS/SQS, CloudWatch, CloudFormation, Apache Airflow, as well as processing applications running on EC2 and other compute resources in the cloud. Software is developed in Python; the AWS Redshift database implements the Postgres API.

 

The first area will be developing, deploying, and designing monitoring for a large number of new data feeds that will be ingested into the Redshift database from internal and external data streams. The technology involved will be SNS/SQS, EC2 autoscaling cluster, AWS Redshift, CloudWatch. The code will be writing in Python, and CloudFormation will be used for deployment. Extensive unit and integrated testing, and continuous deployment will need to be improved or developed. The second area will focus on developing Airflow/Python script-driven SQL and Spark workflows that will utilize data stored in Redshift to generate appropriate downstream BI. The project will involve extensive SQL query optimizations, spinning up EMR clusters, exporting and importing data from Spark clustering, data cleaning, and validation. The final area will focus on improving continuous testing and deployment of our tools, and improving security in the AWS account
