Direct Connect

DX or Direct Connect makes it easy to establish a dedicated network connection from premises to AWS
Using DX, you can establish private connectivity between AWs and data center, office or collocation environment
dedicated connection like MPLS is needed
From this line, you would have a cross connect from on-premises device direct to AWS data centers
DX can
- reduce network costs
- increase bandwidth throughput
- gives consistent network experience compared with internet based connections
Lets you establish a dedicated network connection between network and one of the AWS DX locations
Uses industry standard 802.1Q VLANs
multiple virtual interfaces can be made by dividing dedicated connections
Same connection can be used to access public resources such as objects stored in S3 using public IP’s and private resources such as EC2 instances running in a VPC using private IP’s, all while maintaining network separation between the public and private environments
Virtual interfaces can be reconfigured at any time to meet changing needs
More bandwidth is available with consistent network experience compared to a VPN based solution
VPC VPN connections utilize IPSec to establish encrypted network connectivity between intranet and AWS VPC over the internet
Configuration for VPN connections , requires little time
DX does NOT involve the internet, instead, it uses dedicated private network connections between intranet and AWS VPC
