This […]

Part 1 of this multi-post series discusses design best practices for building scalable ETL (extract, transform, load) and ELT (extract, load, transform) data processing pipelines using both primary and short-lived Amazon Redshift clusters. You also learn about related use cases for some key Amazon Redshift features such as Amazon Redshift Spectrum, Concurrency Scaling, and recent […]

Amazon Redshift is the most popular and the fastest cloud data warehouse. It includes a console for administrators to create, configure, and manage Amazon Redshift clusters. The new Amazon Redshift console modernizes the user interface and adds several features to improve managing your clusters and workloads running on clusters. The new Amazon Redshift console provides visibility to the health and performance of clusters from a unified dashboard, simplified management of clusters by streamlining several screens and flows, improved mean-time-to-diagnose query performance issues by adding capabilities to monitor user queries and correlate with cluster performance metrics, as well as the ability for non-admin users to use Query Editor.

In this post, I show how to use AWS Step Functions and AWS Glue Python Shell to orchestrate tasks for those Amazon Redshift-based ETL workflows in a completely serverless fashion. AWS Glue Python Shell is a Python runtime environment for running small to medium-sized ETL tasks, such as submitting SQL queries and waiting for a response. Step Functions lets you coordinate multiple AWS services into workflows so you can easily run and monitor a series of ETL tasks. Both AWS Glue Python Shell and Step Functions are serverless, allowing you to automatically run and scale them in response to events you define, rather than requiring you to provision, scale, and manage servers.

This post focuses on active security for Amazon Redshift, in particular DataSunrise’s capabilities for masking and access control of personally identifiable information (PII), which you can back with DataSunrise’s passive security offerings such as auditing access of sensitive information. This post discusses DataSunrise security for Amazon Redshift, how it works, and how to get started.

In this post, I explain how to automate the deployment of an Amazon Redshift cluster in an AWS account. AWS best practices for security and high availability drive the cluster’s configuration, and you can create it quickly by using AWS CloudFormation. I walk you through a set of sample CloudFormation templates, which you can customize as per your needs.

In this article, we explain how this customer performed a large-scale data warehouse migration from IBM Netezza to Amazon Redshift without downtime, by following a thoroughly planned migration process, and leveraging AWS Schema Conversion Tool (SCT) and Amazon Redshift best practices.
