In this template, we use S3 as the data source. Technologies. This CloudFormation template will set up an Amazon Redshift cluster, CloudWatch alarms, AWS Glue Data Catalog, an Amazon Redshift IAM role and required configuration. Using three different CloudFormation stacks instead of one nested stack gives you additional flexibility. This template becomes the single source of truth for your infrastructure. This CloudFormation template will create a VPC, subnets, route tables, internet gateway, NAT gateway, Amazon S3 gateway endpoint, and other networking components. We use a condition called “SingleNode” that checks if we have just one node. Redshift is a really powerful data warehousing tool that makes it fast and simple to analyze your data and glean insights that can help your business. Redshift introduced Automatic WLM to solve this queuing problem. A CloudFormation template to set up an Amazon Linux bastion host in an Auto Scaling group to connect to the Amazon Redshift cluster. For the workload management (WLM) configuration, you must supply all the name-value pairs in the wlm_json_configuration parameter. Tags. Option 2 is incorrect since it will be too costly and inefficient to use Lambda. “MasterUserPassword”: This is also a parameter for setting the master password. Stack creation takes a few minutes. I recommend using public subnets for external-facing resources and private subnets for internal resources to reduce the risk of data exfiltration. When I load the template into Cloudformation Designer I get an error when I try to convert it to JSON: 4/15/2019, 4:47:17 PM – Cannot convert the template because of an error:: duplicated mapping key at line 8, column 28: Type: AWS::EC2::VPC::Id ^. Please note that the code snippet below is simplified for demonstration purposes and doesn’t yet match the code we provided in the overall template above. It’s configured as a standalone ingress rule, because CloudFormation resources can’t reference themselves within their own properties. You can also create different rules based on your needs and choose different actions (abort or hop or log). The VPC CloudFormation template takes care of the following: The Amazon Linux bastion host CloudFormation template takes care of the following: The Amazon Redshift cluster template takes care of the following: This creates a custom workload management queue (WLM) with the following configuration: Auto WLM: Amazon Redshift manages query concurrency and memory allocation automatically, as per workload. The following instructions assume that you use a Linux computer and use an SSH client to connect to the bastion host. By completing this process you will be launching a paid EC2 instance that will be the coordinator node for Dremio. Like we mentioned prior, there are a few more Redshift properties that we’ve included in our overall template that we’ll explain in a later section titled “More Redshift cluster properties”.
