Overview In the AWS ecosystem, managing the lifecycle of your data warehouse infrastructure is a critical FinOps discipline. A common source of hidden waste and risk is the continued use of outdated Amazon Redshift clusters running on legacy hardware. This issue arises when clusters, often provisioned years ago, are left on previous-generation nodes like the […]

Overview Amazon Redshift is a powerful, petabyte-scale data warehouse service that often holds an organization’s most sensitive analytical data, from financial records to customer information. A common and dangerous misconfiguration is leaving a Redshift cluster publicly accessible, meaning it can be reached directly from the internet.

Overview In the AWS ecosystem, network segmentation is the first line of defense against unauthorized access and data exfiltration. Amazon Redshift, a service that often houses an organization’s most sensitive analytical data, must be architecturally sound. A foundational element of this architecture is ensuring that every Redshift cluster operates within an Amazon Virtual Private Cloud […]
