What Is Enhanced Vpc Routing

Some housekeeping scripts are being developed using aws amazon web service.

What is enhanced vpc routing. To work with enhanced vpc routing your cluster must meet the following requirements and constraints. Your team has setup a testing environment using a vpc and ec2 instances. But before digging deeper let s do a quick review of traditional fex topologies.

You can now use amazon redshift s enhanced vpc routing to force all of your copy and unload traffic to go through your amazon virtual private cloud vpc. An application is being hosted on these instances. These include such operations as unload to amazon s3 in a.

Each aws vpc has a vpc router. Your cluster must be in a vpc. The vpc endpoint is prioritized as the first route priority.

If one switch fails the other one continues to operate. You might incur additional data transfer charges for certain operations. However when you enable amazon redshift enhanced vpc routing amazon redshift routes the network traffic through a vpc instead.

If enhanced vpc routing is not enabled amazon redshift routes traffic through the internet including traffic to other services within the aws network. Vpc s or virtual port channels are a cisco nexus technology. Enhanced vpc routing supports the use of standard vpc features such as vpc endpoints security groups network acls managed nat and internet gateways enabling you to tightly manage the flow of data between your amazon redshift cluster and all of your data sources.

Fortunately aws offers enhanced vpc routing which allows you to route traffic between s3 and redshift through your vpc meaning you can control all kinds of aspects of this data movement such as dns security groups acls traffic monitoring and loads more. There is no additional charge for using enhanced vpc routing. By using enhanced vpc routing you can use standard vpc features such as vpc security groups network access control lists acls vpc endpoints vpc endpoint policies internet gateways and domain name system dns servers as described in the amazon vpc user guide.
