What Is Enhanced Vpc
If a vpc endpoint is unavailable amazon redshift routes the network traffic through an internet gateway nat instance or nat gateway.
What is enhanced vpc. Aws cloud9 is a cloud based integrated development environment ide that lets you write run and debug your code with just a browser. Amazon redshift enhanced vpc routing uses an available routing option prioritizing the most specific route for network traffic. 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.
Cloud9 is excited to offer enhanced vpc support for customers using the cloud9 ide. The advantages are obvious. In this article i am going to explain common types of port channels that you may come across under different scenarios.
When you use amazon redshift enhanced vpc routing amazon redshift forces all copy and unload traffic between your cluster and your data repositories through your amazon vpc. But before digging deeper let s do a quick review of traditional fex topologies. Enhanced vpc is a method that allows the connection of fex in an active active manner using vpc between the fex and upstream nexus switch and at the same time connection of a device to the fex host interfaces with a vpc.
Common types of port channels. Have you ever wondered about different types of port channels that can be configured. Enhanced vpc is technology that supports the topology that is shown in figure 6 1 where a cisco nexus 2000 fabric extender fex is dual homed to a pair of cisco nexus 5500 series devices while the hosts are also dual homed to a pair of fexs using a vpc.
The vpc endpoint is prioritized as the first route priority. 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.
