VPC components can be interlinked only if they are present in the same AWS Region.

Correct rules for allowing outbound traffic through the subnet ensure that AWS Glue can establish network connectivity with all subnets in the VPC containing the data store, and therefore access the source or target data store. The security group rules and network ACLs associated with the subnet control network traffic through the subnet. The security groups specified in a connection’s properties are applied on each of the network interfaces. Doing this enables ETL jobs and crawlers to connect securely to the data store in the VPC.ĪWS Glue can create this elastic network interface setup if the VPC containing the data store is in the same account and AWS Region as the AWS Glue resources.

If the data store is located inside an Amazon VPC, AWS Glue uses the VPC subnet ID and security group ID connection properties to set up elastic network interfaces in the VPC containing the data store. These properties might include connection information such as user name and password, data store subnet IDs, and security groups. AWS Glue supports connections to Amazon Redshift, Amazon RDS, and JDBC data stores.Ī connection contains the properties needed by AWS Glue to access a data store. AWS Glue ETL jobs also use connections to connect to source and target data stores. AWS Glue connectionsĪWS Glue uses a connection to crawl and catalog a data store’s metadata in the AWS Glue Data Catalog, as the documentation describes.

In this blog post, we describe how to access data stores in an account or AWS Region different from the one where you have AWS Glue resources. AWS Glue uses connections to access certain types of source and target data stores, as described in the AWS Glue documentation.īy default, you can use AWS Glue to create connections to data stores in the same AWS account and AWS Region as the one where you have AWS Glue resources. If you deploy your lambda into your pubic subnets, it's gonna be harder to configure your Redshift Security group.AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load data for analytics. Be careful to deploy your Lambda into your private subnets (to be able to use NAT Gateway EIP) and be sure to have all your routes configured ( ). Then if you still want to use your way be careful of: You will then be able to remove the internet-facing of your Redshift Cluster and only use it with an internal way. Once your VPC peering has been made, you will be able to declare directly you Lambda Security Group to your Redshift Security group to allow inbound access. Be careful to follow all steps for route table. Bind you Lambda VPC to Redshift VPC using a VPC Peering ( ). So you will find below what I recommend to you:

closing Redshift to the public and making the query from an EC2 instance in the VPC where the Lambda function is (put EC2 ip in Redshift security group)Īny idea how to get lambda to use the elastic ip of the NAT or something along those lines? Does the NAT in the route table need to point to elastic ip of Redshift or to a CIDR block or something similar? What am I missing?Īs you said opening your Redshift to internet is really not the best answer, you should really consider using it only in an internet way.

taking lambda out of the VPC and opening Redshift to public (0.0.0.0) which is not ideal.

The NAT is in the route table pointing to Redshift Elastic ip. I added the NAT elastic ip to the security group of Redshift security group.

This is the VPC that the Lambda function is associated with. I have two subnets associated with the VPC and an internet gateway and NAT gateway are attached to the VPC. I have read most of the Stackoverflow questions and heaps of docs on the internet but for some reason can't get lambda to connect to Redshift when Redshift is in a different VPC and different AWS account.
