With cloud computing, as compute energy and knowledge turned extra out there, machine studying (ML) is now making an affect throughout each business and is a core a part of each enterprise and business.
Amazon SageMaker Studio is the primary absolutely built-in ML growth surroundings (IDE) with a web-based visible interface. You possibly can carry out all ML growth steps and have full entry, management, and visibility into every step required to construct, practice, and deploy fashions.
Amazon Redshift is a totally managed, quick, safe, and scalable cloud knowledge warehouse. Organizations typically need to use SageMaker Studio to get predictions from knowledge saved in an information warehouse equivalent to Amazon Redshift.
As described within the AWS Well-Architected Framework, separating workloads throughout accounts permits your group to set widespread guardrails whereas isolating environments. This may be significantly helpful for sure safety necessities, in addition to to simplify value controls and monitoring between tasks and groups. Organizations with a multi-account structure sometimes have Amazon Redshift and SageMaker Studio in two separate AWS accounts. Additionally, Amazon Redshift and SageMaker Studio are sometimes configured in VPCs with personal subnets to enhance safety and cut back the danger of unauthorized entry as a greatest apply.
Amazon Redshift natively supports cross-account knowledge sharing when RA3 node sorts are used. Should you’re utilizing another Amazon Redshift node sorts, equivalent to DS2 or DC2, you should use VPC peering to determine a cross-account connection between Amazon Redshift and SageMaker Studio.
On this submit, we stroll by way of step-by-step directions to determine a cross-account connection to any Amazon Redshift node kind (RA3, DC2, DS2) by connecting the Amazon Redshift cluster positioned in a single AWS account to SageMaker Studio in one other AWS account in the identical Area utilizing VPC peering.
We begin with two AWS accounts: a producer account with the Amazon Redshift knowledge warehouse, and a shopper account for Amazon SageMaker ML use circumstances that has SageMaker Studio arrange. The next is a high-level overview of the workflow:
