AWS Direct connect

 AWS Direct connect: is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Using AWS direct connect, you can establish private connectivity between AWS and your data center, office, or colocation environment - which, in many cases, can reduce your network costs, increase bandwidth throughput, and provides a more consistent network experience than internet- based connections.
