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.

This post describes how to make the MIMIC-III dataset available in Athena and provide automated access to an analysis environment for MIMIC-III on AWS. We also compare a MIMIC-III reference bioinformatics study using a traditional database to that same study using Athena.

In this post, you will learn how to use the metadata search capabilities of Lake Formation. By defining specific user permissions, Lake Formation allows you to grant and revoke access to metadata in the Data Catalog as well as the underlying data stored in S3.

In this post, you will create and edit your first data lake using the Lake Formation. You will use the service to secure and ingest data into an S3 data lake, catalog the data, and customize the metadata of the data sources. In part 2 of this series, we will show you how to discover your data by using the metadata search capabilities of Lake Formation.

AWS Lake Formation enables you to set up a secure data lake. A data lake is a centralized, curated, and secured repository storing all your structured and unstructured data, at any scale. You can store your data as-is, without having first to structure it. And you can run different types of analytics to better guide […]

AWS Lake Formation FindMatches is a new machine learning (ML) transform that enables you to match records across different datasets as well as identify and remove duplicate records, with little to no human intervention. FindMatches is part of Lake Formation, a new AWS service that helps you build a secure data lake in a few simple steps.

To use FindMatches, you don’t have to write code or know how ML works. Your data doesn’t have to include a unique identifier, nor must fields match exactly.

A data lake is a centralized store of a variety of data types for analysis by multiple analytics approaches and groups. Many organizations are moving their data into a data lake. In this post, we explore how you can use AWS Lake Formation to build, secure, and manage data lakes.

This post presents a simple approach to aggregating AWS WAF logs into a central data lake repository, which lets teams better analyze and understand their organization’s security posture. I walk through the steps to aggregate regional AWS WAF logs into a dedicated S3 bucket. I follow that up by demonstrating how you can use Amazon ES to visualize the log data. I also present an option to offload and process historical data using AWS Glue ETL. With the data collected in one place, I finally show you how you can use Amazon Athena and Amazon QuickSight to query historical data and extract business insights.

Amazon always works backwards from the customer’s needs. Customers have made strong requests that they want stored procedures in Amazon Redshift, to make it easier to migrate their existing workloads from legacy, on-premises data warehouses.

With that primary goal in mind, AWS chose to implement PL/pqSQL stored procedure to maximize compatibility with existing procedures and simplify migrations. In this post, we discuss how and where to use stored procedures to improve operational efficiency and security. We also explain how to use stored procedures with AWS Schema Conversion Tool.
