In this, we will learn about Direct Connect (DX).

SOA-C01 exam is updated to AWS Certified SysOps Administrator – Associate (SOA-C02).

USe of Direct Connect (DX):

• DX or Direct Connect makes it easy to establish a dedicated network connection from your premises to AWS
• Using DX, you can establish private connectivity between AWs and your data center, office or collocation environment
• Requires a dedicated line such as MPLS, or other circuit ran from tel-co.
• From this line, you would have a cross connect from your on-premises device direct to AWS data centers
• Using DX, can reduce network costs, increase bandwidth throughput and provide a more consistent network experience then internet based connections
• Lets you establish a dedicated network connection between your network and one of the AWS DX locations
• Uses industry standard 802.1Q VLANs
• Dedicated connections can partitioned into multiple virtual interfaces
• Same connection can 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 reconfigure at any time to meet changing needs
• Offers more bandwidth and a more consistent network experience over using VPN based solutions
• VPC VPN connections utilize IPSec to establish encrypted network connectivity between your intranet and your AWS VPC over the internet
• VPN connections can configure in minutes and are a good solution if you have an immediate need
• DX does NOT involve the internet, instead, it uses dedicated private network connections between your intranet and AWS VPC
